Pour 2 Tbs. of the chocolate syrup and 2 Tbs. of the club soda into each of 4 tall glasses. Stir to combine. Drop a 1/2-cup scoop of ice cream into each glass. Drizzle 2 Tbs. of the espresso and 2 Tbs. of the Kahlúa over each portion. Fill the remainder of each glass with club soda. Serve immediately with a straw and a long-handled spoon.
Put a 1/2-cup scoop of ice cream in each of 4 tall glasses. Drizzle 2 Tbs. Sambuca over each one and top off with club soda. Serve immediately with a straw and a long-handled spoon.
Position a rack in the center of the oven and heat the oven to 375°F.
In a medium bowl, stir together the chocolate wafer crumbs and 3 Tbs. granulated sugar. Mix in the melted butter until the crumbs are evenly moist and clump together slightly. Transfer the mixture to a 9-inch springform pan and press evenly onto the bottom and about 2 inches up the sides of the pan (to press, use plastic wrap or a flat-bottom measuring cup). Bake until the crust is fragrant and slightly darkened, 9 to 12 minutes. Let the pan cool on a rack. Lower the oven temperature to 300°F.
In a stand mixer fitted with the paddle attachment, beat the cream cheese, crème fraîche, flour, and a pinch of table salt on medium speed, scraping down the sides of the bowl and the paddle frequently, until very smooth and fluffy, about 5 minutes. Make sure the cheese has no lumps. Add the 1-1/4 cups granulated sugar and continue beating until well blended and smooth.
Add the vanilla and instant espresso powder and beat until blended, about 30 seconds. Add the eggs one at a time, beating just until blended. (Don’t overbeat once the eggs have been added or the cheesecake will puff too much and crack as it cools.) Pour the filling into the cooled crust and smooth the top.
Bake at 300°F until the center jiggles like Jell-O when nudged, 55 to 65 minutes. The cake will be slightly puffed around the edges, and the center will still look moist. Set on a rack and cool completely. Cover and refrigerate until well chilled, at least 8 hours and up to 3 days. The cake can also be frozen at this point for up to 1 month (see make-ahead tip, below).
Unclasp and remove the side of the springform pan and run a long, thin metal spatula under the bottom crust. Carefully slide the cake onto a flat serving plate.
Garnish with chocolate-covered espresso beans and serve immediately. To cut, run a thin knife under hot water, wipe it dry, and cut the cake into slices, heating and wiping the knife after every slice.
Lightly grease a 6-cup loaf pan. Line the pan with two pieces of overlapping plastic wrap, allowing the excess to hang over the edges of the pan.
In a bowl, combine the cream, espresso powder, and sugar. Whisk until the cream holds firm peaks. Spoon about two-thirds of the whipped cream into the prepared pan. Tap the pan firmly on the counter to even the cream and eliminate any air bubbles.
Starting at a short side of the pan, arrange 11 cookies in the cream, standing them on their edge in a row like dominoes. Gently squeeze the cookies together as you go. Do the same with a second row of cookies, slightly overlapping the cookies from the second row with the cookies in the first row. Continue with two more rows for a total of four rows.
Press down on the cookies gently. Cover them with the remaining cream. Smooth the cream with a spatula, gently pressing to make sure any gaps between the cookies are filled. Tap the pan on the counter several times to eliminate any air pockets.
Cover the cake with the excess plastic wrap and refrigerate at least 24 hours, preferably 2 days. When ready to serve, peel the plastic wrap from the top and gently tug on the plastic to loosen the cake from the sides of the pan. Set a cutting board on top of the pan and invert the cake onto the board. Lift the pan off and gently peel away the plastic wrap. Mix the hazelnuts with the cookie crumbs and sprinkle over the top of the cake. Slice carefully with a warm knife.
Line a baking sheet with kitchen parchment and spray the parchment with nonstick cooking spray or grease it lightly. In a medium heavy-based saucepan, combine the sugar and water. Heat over high heat, swirling the pot occasionally (don't stir it) for even color, until it turns light amber. Add the crushed espresso beans (don't worry if the sugar seems to foam), swirl them around in the caramel, and continue to cook until the caramel turns brown. Remove the pan from the heat. Carefully whisk in the butter and salt (the butter will sputter). Immediately pour the brittle onto the prepared baking sheet, quickly tilting the baking sheet to get the brittle to flow into a thin layer (be careful—the brittle is very hot). As it cools and slows down, use a metal spatula to spread it into an even thinner layer. Let cool. Chop two-thirds of the cooled brittle into small pieces by sealing it in a plastic bag and smashing it with a mallet or rolling pin. Sift the crumbs in a strainer if you don't want the powder. Break the remaining brittle into shards and use them to garnish bowls of the ice cream.
Heat the oven to 350°F. Using a stand mixer with the paddle attachment or a regular mixer with beaters, combine the flour, baking powder, salt, baking soda, 2/3 cup brown sugar, and the ground coffee beans. Add the butter and mix on low speed until the pieces of butter are the size of marbles. Add the cream, vanilla, and cold espresso and continue mixing until the dough just comes together. Pat the dough onto an ungreased baking sheet into a round about 6 inches in diameter. Mix the 1 tsp. brown sugar with the white sugar to make it "sprinkleable." Sprinkle the round lightly with the sugar and cut it into 8 triangles. Bake until firm but still springy, 40 to 50 minutes. Remove from the oven and cool. Cut into wedges along the lines.
Pour 2 Tbs. of the chocolate syrup and 2 Tbs. of the club soda into each of 4 tall glasses. Stir to combine. Drop a 1/2-cup scoop of ice cream into each glass. Drizzle 2 Tbs. of the espresso and 2 Tbs. of the Kahlúa over each portion. Fill the remainder of each glass with club soda. Serve immediately with a straw and a long-handled spoon.
Pulse the flour, sugar, and salt in a food processor just to blend. Add the butter and shortening and pulse several times until the mixture resembles coarse cornmeal, 8 to 10 pulses. Transfer the mixture to a medium bowl. Tossing and stirring quickly with a fork, gradually add enough cold water (2 to 4 Tbs.) that the dough just begins to come together. It should clump together easily if lightly squeezed but not feel wet or sticky. With your hands, gather the dough and form it into a ball. Flatten the ball into a disk and wrap it in plastic. Chill the dough for 2 hours or up to 2 days before rolling. The dough can also be frozen for up to 2 months; thaw it overnight in the refrigerator before using.
Remove the dough from the refrigerator and let it sit at room temperature until pliable, 10 to 15 minutes. On a lightly floured surface with a lightly floured rolling pin, roll the dough into a 1/8-inch-thick, 13-inch-diameter round. Be sure to pick up the dough several times and rotate it, reflouring the surface lightly to prevent sticking. I use a giant spatula or the bottom of a removable-bottom tart pan to move the dough around. Transfer the dough to a 9-inch Pyrex pie pan and trim the edges so there's a 1/2-inch overhang. Fold the overhang underneath itself to create a raised edge and then decoratively crimp or flute the edge. (Save the scraps for patching the shell later, if necessary). Chill until the dough firms up, at least 45 minutes in the refrigerator or 20 minutes in the freezer.
Position a rack in the center of the oven and heat the oven to 350°F. Line the pie shell with parchment and fill with dried beans or pie weights. Bake until the edges of the crust are light golden brown, 25 to 30 minutes. Carefully remove the parchment and beans or weights. If necessary, gently repair any cracks with a smear of the excess dough. Transfer the shell to a rack to cool.
Melt the chocolate and butter in the microwave or in a small metal bowl set in a skillet of barely simmering water, stirring with a rubber spatula until smooth.
In a medium mixing bowl, whisk the eggs, corn syrup, sugar, and salt. Dissolve the instant espresso in 1 Tbs. hot water and add to the egg mixture, along with the coffee liqueur and the melted chocolate and butter. Whisk to blend.
Evenly spread the toasted pecan pieces in the pie shell. To form a decorative border, arrange the pecan halves around the perimeter of the pie shell, on top of the pecan pieces, keeping the points of the pecans facing in and the backs just touching the crust. Carefully pour the filling over the pecans until the shell is three-quarters full. Pour the remaining filling into a liquid measuring cup or small pitcher. Transfer the pie to the oven and pour in the remaining filling. (The pecans will rise to the top as the pie bakes.)
Bake the pie until the filling puffs up, just starts to crack, and appears fairly set, 45 to 55 minutes. Transfer it to a rack and allow it to cool completely (at least 4 hours) before serving.
Lightly butter the face of a candy thermometer and set aside.
Put the sugar, cream, chocolate, corn syrup, instant coffee, and salt in a large (4-quart) heavy-duty saucepan and stir with a spoon or heatproof spatula until the ingredients are moistened and combined. Stirring gently and constantly, bring the mixture to a boil over medium heat, 7 to 12 minutes. Cover the saucepan and let the steam clean the sides of the pan for 2 minutes.
Clip the candy thermometer to the pot, being careful not to let the tip of the thermometer touch the bottom of the pot, or you might get a false reading. Let the mixture boil without stirring until it reaches 236°F to 238°F, 2 to 5 minutes. Take the pan off the heat and add the butter, but do not stir it into the mixture. Set the pan on a rack in a cool part of the kitchen. Don’t disturb the pan in any way until the mixture has cooled to 110°F, 1 to 1-1/2 hours.
Meanwhile, line the bottom and sides of an 8x8-inch baking pan with foil, leaving a 2-inch overhang on two opposite sides of the pan. Butter the foil. Set the pan aside.
Remove the thermometer from the fudge mixture. Using a hand mixer, beat the mixture on high speed until it is a few shades lighter in color and thickens enough that the beaters form trails that briefly expose the bottom of the pan as they pass through, 10 to 20 minutes. After beating the fudge, stir in 1/2 cup cocoa nibs. Pour the thickened fudge into the prepared pan, using a rubber spatula to help nudge it out of the pot. You can scrape the bottom of the pot but not the sides; any crystals that stick to the pot stay in the pot. Smooth the top of the fudge with the spatula. If you like, lightly score the fudge into 25 pieces and place a coffee bean in the center of each piece. Set the pan on a rack and let the fudge cool completely, about 2 hours. The fudge will be slightly soft the day it’s made but will firm up overnight.
Turn the fudge out onto a clean cutting board and peel off the foil. Turn the slab of fudge right side up and cut it into 25 equal pieces.
The fudge will keep for a week to 10 days stored in an airtight container at room temperature.
Heat the oven to 350°F. Line a rimmed sheet pan or jelly roll pan measuring 14x11 inches or 15x10 inches (or quite close to those measurements) with kitchen parchment. Using a stand mixer with its whisk attachment or an electric mixer, beat the egg yolks, 1/3 cup of the sugar, and the hot espresso on high until thick and voluminous, at least 6 minutes. In another bowl and with clean beaters, whisk the egg whites on medium speed. When they reach the soft-peak stage, slowly add the remaining 1/3 cup sugar with the mixer running. Increase the speed to medium high and beat until the whites are glossy and smooth with peaks that hold their shape without drooping, another 1 or 2 minutes. Fold one-third of the whites into the yolk mixture to lighten them, and then gently fold in the rest of the whites. Sift the flour and salt over the top of the mixture and fold it in gently. Spread the batter evenly on the prepared sheet pan. Bake until the center of the cake springs back when lightly pressed and the cake doesn't stick to your fingers, 12 to 14 minutes. Remove from the oven and cool for 5 minutes. Run a knife around the edge of the cake and invert it onto a cooling rack. Gently peel off the parchment and allow the cake to cool completely.
Set a pan of water to simmer and fill a large bowl with ice. In a medium stainless-steel bowl, whisk together the egg yolks, sugar, coffee liqueur, and salt. Set the bowl over, but not touching, the simmering water and whisk until the mixture thickens, the whisk leaves ribbons trailing off of it, and you can see the bottom of the bowl when you scrape the whisk along the bottom, 6 to 7 minutes. Cool the yolk mixture by setting the bowl on the ice bath and whisking the mixture occasionally. Meanwhile, whisk together the mascarpone and cream until it holds peaks. When the yolk mixture is cool, gently fold in the cream mixture until combined. Keep the mixture cool.
Divide the sponge cake into thirds (three rectangles about 4-1/2x11 or 5x10 inches). Lay one of the cake rectangles on the bottom of a rectangular pan (I use a Pyrex baking dish). Brush its top liberally with one-third of the hot espresso. Spread just under half of the mascarpone filling over the cake. Grate about one-third of the unsweetened chocolate on top of the mascarpone. Repeat with another layer of cake, espresso, mascarpone filling, and chocolate. Top with the last layer of cake, brush on the last of the coffee, spread on a very thin layer of mascarpone, and grate the rest of the chocolate on top. Refrigerate for several hours or overnight before serving. Slice and serve.
Line a baking sheet with kitchen parchment and spray the parchment with nonstick cooking spray or grease it lightly. In a medium heavy-based saucepan, combine the sugar and water. Heat over high heat, swirling the pot occasionally (don't stir it) for even color, until it turns light amber. Add the crushed espresso beans (don't worry if the sugar seems to foam), swirl them around in the caramel, and continue to cook until the caramel turns brown. Remove the pan from the heat. Carefully whisk in the butter and salt (the butter will sputter). Immediately pour the brittle onto the prepared baking sheet, quickly tilting the baking sheet to get the brittle to flow into a thin layer (be careful—the brittle is very hot). As it cools and slows down, use a metal spatula to spread it into an even thinner layer. Let cool. Chop two-thirds of the cooled brittle into small pieces by sealing it in a plastic bag and smashing it with a mallet or rolling pin. Sift the crumbs in a strainer if you don't want the powder. Break the remaining brittle into shards and use them to garnish bowls of the ice cream.
Combine the brown sugar and 2 Tbs. water in a 1-quart saucepan and stir over low heat until the sugar is just dissolved. You’ll have 1/4 cup of syrup; depending on how sweet you like your Irish coffee, you may not need it all.
Pour 1/2 cup of the coffee, 3 Tbs. of the whiskey, and 2 to 3 tsp. of the brown sugar syrup into each of 4 warmed 6-oz. glass Irish coffee mugs.
In a medium bowl, beat the cream with a whisk just until it’s frothy and slightly thickened but does not yet hold a peak, about 1 minute. With a soup spoon, float about 3/4 inch of the lightly whipped cream on top of each coffee and serve immediately.
Position racks in the upper and lower thirds of the oven and heat the oven to 350°F. Butter three 9x2-inch round cake pans and line the bottoms with parchment. Butter the parchment.
In a stand mixer fitted with the whisk attachment (or in a large bowl, using an electric hand-held mixer), briefly blend the flour, sugar, cocoa, baking powder, baking soda, and salt on low speed. Add the eggs, milk, oil, and vanilla and mix at low speed, scraping the bowl as necessary, until the mixture is thick and creamy, like chocolate frosting, about 5 minutes. With the mixer running, gradually add the hot coffee, mixing at low speed just until combined. The batter will be quite thin. Divide the batter equally among the pans.
Bake, switching positions and rotating the pans halfway through, until a tester inserted in the center of the cake comes out with only a few crumbs clinging to it and the center feels firm to the touch, 20 to 25 minutes. Let the cakes cool completely in the pans on racks.
Clean and chill the mixing bowl and whisk attachment. In a measuring cup, stir the instant espresso into the whiskey until completely dissolved. In the chilled bowl, whip the cream, brown sugar, and whiskey mixture on medium-high speed until medium peaks form, 2 to 3 minutes.
Run a thin knife around the inside edge of the cake pans and turn the cakes out onto a large cutting board; peel off the parchment.
Transfer one layer to a cake plate and spread a third of the whipped cream on top, leaving a 1/2-inch border; repeat with the second layer. Put the top layer in place and spread the remaining whipped cream out to the edge.
To make the chocolate shavings, put a piece of waxed paper or foil on a baking sheet. Microwave each block of chocolate on medium power for 20 to 30 seconds to soften slightly, then draw a vegetable peeler along the chocolate bar’s edge, letting the curls fall onto the waxed paper. Make enough curls of both colors to top the cake generously, 1-1/2 to 2-1/2 oz. each. Refrigerate the shavings to make them easier to handle.
Arrange the shavings on top of the cake and serve.
Position a rack in the center of the oven and heat the oven to 350°F.
Butter the bottom and sides of a 9x13-inch Pyrex baking dish or a nonreactive metal pan. Line the bottom of the baking dish or pan with parchment and lightly butter the parchment.
Sift the flour, baking powder, and salt into a medium bowl and set aside.
Separate the eggs, putting the whites in a medium bowl and the yolks in a large bowl. With an electric mixer, beat the yolks with 3/4 cup of the sugar on medium speed until the mixture is pale and creamy, about 2 minutes. Add the milk and vanilla and beat until combined, 1 minute more.
Clean and dry the beaters and then beat the egg whites, gradually increasing the speed to high, until they reach soft peaks, 2 to 3 minutes. Add the remaining 1/4 cup sugar in a stream, continuing to beat on high, until you reach firm but not dry peaks, 1 to 2 minutes more. Whisk a third of the dry ingredients into the yolk mixture until thoroughly combined. Gently fold in a third of the egg whites with a rubber spatula. Fold in the remaining dry ingredients and egg whites, alternately, in two more batches each, until fully incorporated.
Pour the batter into the prepared dish or pan and bake until a toothpick inserted in the center comes out clean, 20 to 25 minutes. Let the cake cool in the pan on a rack for 10 minutes, then invert the cake onto the rack, remove the parchment, and let cool completely.
Return the cake to the baking dish or pan (the cake will soak up more of the liquid if returned to the pan it was baked in), or invert it onto a rimmed platter.
In a 2 quart saucepan, stir together the condensed milk, evaporated milk, heavy cream, coffee, and salt until the condensed milk is well blended. Cook over medium-low heat, stirring to avoid scorching, until it begins to bubble around the edges, 3 to 5 minutes. Remove from the heat and pour into a heatproof 4 cup measuring cup.
With a toothpick, prick the cake to the bottom in 1/2-inch intervals. Pour the soaking liquid slowly over the cake, starting at the edges and pausing to let it soak in before adding more. Cover loosely with plastic wrap and refrigerate until the cake is well chilled, at least 2 hours and up to 24 hours.
In a large bowl, stir the instant coffee into 2 Tbs. of the heavy cream until dissolved. Add the remaining cream and beat with an electric mixer on medium speed. When it begins to thicken, slowly add the sugar and vanilla and continue to beat just until it holds firm peaks, 3 to 4 minutes (be careful not to overbeat). Spread the whipped cream all over the top of the cake, sprinkle the chocolate curls or almonds over the top, and serve.
Bring 1 cup water to a boil. Put the condensed milk in a mug and put a stainless steel Vietnamese coffee filter (or a drip cone lined with a paper filter) over the mug and add the ground coffee.
Pour 1 to 2 Tbs. of the boiling water over the coffee to let the grounds expand. If using a stainless steel filter, put the filter insert over the coffee and fill it with 4 to 5 more oz. hot water, and put the lid on (if using a drip cone, slowly pour the water directly over the grounds).
Once all the water has dripped through, stir together the coffee and condensed milk. Add more hot water to taste.
In a medium saucepan, heat the cream, milk, and crushed coffee beans to just under a boil. Remove from the heat and let stand at least 1 hour for the beans to infuse their flavor. In a medium bowl, whisk together the egg yolks and sugar. Pour the cream mixture into the egg yolks, whisking until well blended. Return this mixture to the saucepan and cook over medium heat, stirring constantly, until it thickens slightly, enough to coat the back of a wooden spoon. Strain the custard through a fine mesh sieve and chill. Freeze in an ice-cream maker following the manufacturer's instructions. When frozen but still soft, transfer the ice cream to a stainless-steel bowl and swirl in the chopped brittle with a spatula. Cover the ice cream tightly with plastic wrap and freeze. Garnish with the remaining shards of brittle, when serving, if you like.
Pulse the flour, sugar, and salt in a food processor just to blend. Add the butter and shortening and pulse several times until the mixture resembles coarse cornmeal, 8 to 10 pulses. Transfer the mixture to a medium bowl. Tossing and stirring quickly with a fork, gradually add enough cold water (2 to 4 Tbs.) that the dough just begins to come together. It should clump together easily if lightly squeezed but not feel wet or sticky. With your hands, gather the dough and form it into a ball. Flatten the ball into a disk and wrap it in plastic. Chill the dough for 2 hours or up to 2 days before rolling. The dough can also be frozen for up to 2 months; thaw it overnight in the refrigerator before using.
Remove the dough from the refrigerator and let it sit at room temperature until pliable, 10 to 15 minutes. On a lightly floured surface with a lightly floured rolling pin, roll the dough into a 1/8-inch-thick, 13-inch-diameter round. Be sure to pick up the dough several times and rotate it, reflouring the surface lightly to prevent sticking. I use a giant spatula or the bottom of a removable-bottom tart pan to move the dough around. Transfer the dough to a 9-inch Pyrex pie pan and trim the edges so there's a 1/2-inch overhang. Fold the overhang underneath itself to create a raised edge and then decoratively crimp or flute the edge. (Save the scraps for patching the shell later, if necessary). Chill until the dough firms up, at least 45 minutes in the refrigerator or 20 minutes in the freezer.
Position a rack in the center of the oven and heat the oven to 350°F. Line the pie shell with parchment and fill with dried beans or pie weights. Bake until the edges of the crust are light golden brown, 25 to 30 minutes. Carefully remove the parchment and beans or weights. If necessary, gently repair any cracks with a smear of the excess dough. Transfer the shell to a rack to cool.
Melt the chocolate and butter in the microwave or in a small metal bowl set in a skillet of barely simmering water, stirring with a rubber spatula until smooth.
In a medium mixing bowl, whisk the eggs, corn syrup, sugar, and salt. Dissolve the instant espresso in 1 Tbs. hot water and add to the egg mixture, along with the coffee liqueur and the melted chocolate and butter. Whisk to blend.
Evenly spread the toasted pecan pieces in the pie shell. To form a decorative border, arrange the pecan halves around the perimeter of the pie shell, on top of the pecan pieces, keeping the points of the pecans facing in and the backs just touching the crust. Carefully pour the filling over the pecans until the shell is three-quarters full. Pour the remaining filling into a liquid measuring cup or small pitcher. Transfer the pie to the oven and pour in the remaining filling. (The pecans will rise to the top as the pie bakes.)
Bake the pie until the filling puffs up, just starts to crack, and appears fairly set, 45 to 55 minutes. Transfer it to a rack and allow it to cool completely (at least 4 hours) before serving.
Lightly grease a 6-cup loaf pan. Line the pan with two pieces of overlapping plastic wrap, allowing the excess to hang over the edges of the pan.
In a bowl, combine the cream, espresso powder, and sugar. Whisk until the cream holds firm peaks. Spoon about two-thirds of the whipped cream into the prepared pan. Tap the pan firmly on the counter to even the cream and eliminate any air bubbles.
Starting at a short side of the pan, arrange 11 cookies in the cream, standing them on their edge in a row like dominoes. Gently squeeze the cookies together as you go. Do the same with a second row of cookies, slightly overlapping the cookies from the second row with the cookies in the first row. Continue with two more rows for a total of four rows.
Press down on the cookies gently. Cover them with the remaining cream. Smooth the cream with a spatula, gently pressing to make sure any gaps between the cookies are filled. Tap the pan on the counter several times to eliminate any air pockets.
Cover the cake with the excess plastic wrap and refrigerate at least 24 hours, preferably 2 days. When ready to serve, peel the plastic wrap from the top and gently tug on the plastic to loosen the cake from the sides of the pan. Set a cutting board on top of the pan and invert the cake onto the board. Lift the pan off and gently peel away the plastic wrap. Mix the hazelnuts with the cookie crumbs and sprinkle over the top of the cake. Slice carefully with a warm knife.
Heat the oven to 350°F. Fit a large pastry bag with a plain #7 tip (about 1/2 inch). Line a large baking sheet with parchment. Set a 10 1/2x 5 1/2 x3 -inch loaf pan on one of its longer sides on the top part of the parchment. Trace the edge with a pencil. Move the pan down about 2 inches and trace the side edge again. Move the pan down another 2 inches and set the pan right side up. Trace the bottom. Flip the paper over.
In a small bowl, combine the flour, hazelnuts, and baking powder with a whisk until well blended. Put the yolks in a large bowl of an electric mixer, fitted with a whisk attachment if you have one. Add the vanilla and beat on medium-high speed until foamy. Gradually add all but 2 Tbs. of the sugar while beating. Continue beating until the mixture is pale yellow and tripled in volume. When the whisk is lifted, the mixture will fall back into the bowl and form a ribbon; it should linger a bit on the surface. Set aside. In a clean bowl with a well-cleaned whisk attachment (or beaters), add the whites and the salt. Beat on medium speed until the whites are frothy and have doubled in volume. Gradually add the remaining 2 Tbs. sugar and beat on high speed until the whites form medium-firm peaks. With a large spatula, scoop about a third of the whites into the yolk mixture. Gently stir until just combined. Add half of the remaining whites and carefully fold in. Sprinkle half of the flour mixture over the surface of the yolk-white mixture and fold in with a couple of gentle strokes. Fold in the remaining whites. Sprinkle the remaining flour over the top and gently fold in.
To pipe the ladyfingers, scoop the batter into the pastry bag using deep, cutting strokes to prevent the batter from deflating (see How to fill a pastry bag). Twist the top of the bag closed. Hold the bag about 2 inches above the parchment-lined sheet. Gently squeezing from the top, pipe the batter into short, thin strips just barely touching each other and keeping within the template. For optimum lightness, let the batter fall gently from the bag and finish each ladyfinger with a small lift of the wrist. You should have about 10 ladyfingers on the bottom template and about 12 for each side. Remember to stop between ladyfingers and twist down the top of the bag to keep the batter flowing smoothly. You’ll have a little extra batter; pipe more ladyfingers for a snack, but bake them after the first batch is done.
To bake the ladyfingers, sprinkle the hazelnut and sugar mixture over the tops of the ladyfinger strips. Bake until puffed and the tops are golden brown, 15 to 18 minutes. Slide the parchment onto a cooling rack and cool until just barely warm, about 15 minutes. Carefully peel the strips from the parchment, keeping the rows intact. Let cool completely.
Lightly grease or spray the mold and line with two long sheets of plastic wrap to cover the bottom and sides. Set the bottom row of ladyfingers into the pan, topping side facing down. It should be a snug fit. Next, lean the two remaining rows against the long sides, topping side facing out. Again the fit should be snug. Don’t worry if they peek above the sides of the pan -- you’ll trim them later.
Melt the chopped chocolate in a double boiler or microwave and set aside. Don’t do this too much ahead—you’ll want to use it while it’s still warm. In a large bowl, combine the heavy cream, 1/3 cup of the superfine sugar, and the Frangelico. Beat until lightly whipped, about 1 minute; the mixture should be thickened but not enough to hold soft peaks. Set aside. In a large bowl of an electric mixer, beat the butter and the remaining 1/3 cup superfine sugar on medium speed with the paddle attachment (or beaters) until well blended and almost smooth. Don’t worry if some sugar grains linger. Add the cocoa powder. Mix with slow pulses, stopping to scrape down the sides, until blended. Add the egg yolks one at a time, beating well before adding the next. Check the temperature of the melted chocolate; it should still be warm. If not, set it over simmering water until warm. Pour it into the cocoa mixture and beat on low speed until well blended. Remember to scrape down the sides and bottom of the bowl. With the mixer on low, slowly drizzle in the cream, stopping a few times to scrape down the sides. Stop as soon as the cream is mixed in.
Using a large rubber spatula, pack the filling into the ladyfinger-lined pan. Cover the surface with plastic wrap and fold the remaining plastic over the filling and the ladyfingers. Refrigerate until the filling is firm, at least overnight or up to 3 days.
In a medium saucepan, bring the heavy cream to a boil. Reduce the heat and simmer vigorously until the cream is thick enough to coat the back of a spoon (you’ll have about 2 cups), about 10 minutes. Remove from the heat and whisk in the sugar and espresso or coffee powder until dissolved. Taste and adjust. Cover the surface with plastic wrap and chill until ready to serve.
Peel the plastic away from the surface. Using a serrated knife, trim the ladyfingers down to the level of the filling. Invert the marquise onto a flat platter and tug on the plastic to release the marquise from the mold. Remove the plastic. Using a serrated knife, cut through the ladyfingers, down to but not into the filling. Run a sharp, thin knife under very hot water and wipe it off. Immediately cut down through one slice and lift the knife directly back up. Repeat, using both knives and heating the thin one for each slice. Serve with the coffee cream.
