CHOCOLATE LAYER CAKE WITH SWISS BUTTERCREAM AND GANACHE

Steps:

• Make the cake: Preheat the oven to 350˚ F. Butter and flour two 9-inch round cake pans and line the bottoms with parchment paper. Put the cocoa powder and chocolate in a medium bowl. Add the boiling water and whisk until the chocolate is melted. Whisk in the sour cream until smooth; let cool to room temperature.
• Whisk the flour, baking soda and salt in a medium bowl; set aside. Beat the butter, granulated sugar and brown sugar in a large bowl with a mixer on medium-high speed until fluffy, 3 to 4 minutes. Add the eggs, one at a time, then the vanilla, beating well after each addition. Reduce the mixer speed to low. Beat in the flour mixture in 3 additions, alternating with the cocoa mixture in 2 additions. Finish mixing gently with a rubber spatula, scraping the bottom and sides of the bowl.
• Divide the batter evenly between the cake pans. Tap the pans against the counter to eliminate any air bubbles. Bake until the cakes spring back in the center when gently pressed, 35 to 40 minutes. Let the cakes cool in the pans for 10 minutes, then run an offset spatula around the edges and turn out the cakes onto a rack to cool completely. Remove the parchment.
• Make the frosting: Bring a few inches of water to a simmer in a medium saucepan over medium heat. Whisk the egg whites, granulated sugar and salt in the bowl of a stand mixer. Set the bowl over the saucepan (do not let the bottom of the bowl touch the water); cook, whisking, until the sugar dissolves, the egg whites are frothy and the mixture is warm, 3 to 5 minutes.
• Transfer the bowl to the stand mixer and beat with the whisk attachment on medium-high speed until stiff glossy peaks form and the mixture cools to room temperature, about 5 minutes. With the mixer running, add the butter a few pieces at a time, waiting for them to incorporate before adding more. (The mixture will become liquidy, then it will get thick and shiny once the butter emulsifies. It may also look curdled as you add the butter. It's OK: Keep adding butter and beating.) Add the vanilla and beat until combined and fluffy, 3 to 5 more minutes.
• Cut each cake in half horizontally to create 4 layers. Place 1 layer on a cake stand or serving plate. Spread about 2/3 cup frosting on top, then repeat with the remaining cake layers, spreading more frosting in between them. Spread a thin layer of frosting on the top and sides of the cake (this is the crumb coat - it doesn't have to be perfect), then refrigerate until the frosting sets, about 30 minutes. Spread the remaining frosting all over the top and sides of the cake, smoothing it with a bench scraper.
• Make the ganache: Heat the heavy cream in a saucepan over medium-high heat until steaming, then pour over the chocolate in a small heatproof bowl. Let sit for 5 minutes, then stir until smooth. Set aside until cool but still pourable, 20 to 40 minutes (the time will vary depending on the temperature and bowl). Pour the ganache on top of the cake and spread with a small offset spatula, letting it drip down the sides. Let the ganache set 20 to 30 minutes before slicing.

TRIPLE HAZELNUT CAKE WITH CHOCOLATE BUTTERCREAM FROSTING

Steps:

• To make the cake, grease 2 (9 by 2-inch) round cake pans with shortening and line bottoms with parchment rounds. Grease parchment and dust each pan with 1 tablespoon flour, shaking out excess. Set pans aside.
• Preheat oven to 350 degrees F.
• In a medium bowl whisk together the eggs, liqueur, and hazelnut extract until blended and set aside.
• In a large bowl of an electric stand mixer, gently combine on low speed 3 1/3 cups flour, sugar, baking powder, baking soda, salt and hazelnuts until blended. Add the butter and sour cream and beat on low speed until dry ingredients are moistened.
• Increase speed to medium and beat for 2 1/2 minutes, scraping the sides of the bowl occasionally. In 3 separate additions, add the egg mixture to the batter, beating for 30 seconds after each addition. Divide batter evenly into the prepared pans and bake on the center rack for 40 to 45 minutes or until a cake tester inserted into the center of each cake comes out clean. Cool cakes in pans for 10 minutes. Remove from pans, discard parchment and cool cakes completely on wire racks, 1 to 2 hours.
• To make the hazelnut filling, in a medium saucepan melt the butter over medium heat.
• Sprinkle with flour and whisk until smooth. Reduce heat to medium-low, add the sugar and cream and cook, whisking constantly, for 7 to 10 minutes or until mixture is thickened. Stir in the hazelnuts, salt, liqueur, hazelnut extract, and chocolate and cook just until chocolate melts. Set aside in a bowl and cool completely.
• To make the chocolate buttercream frosting, melt chocolate in the top of a double boiler over medium heat until smooth. Set aside, off the heat, and cool completely. In a large bowl whisk together the sugar and egg whites until blended. Place the bowl over a saucepan of simmering water and whisk until mixture reaches 140 degrees F.
• Remove mixture to a large bowl of a stand mixture with a whisk attachment and beat on low speed for 1 minute to cool slightly. Increase speed to high and beat for 4 minutes or until mixture is cool to the touch and doubled in volume. Reduce speed to low and add the softened butter 1 tablespoon at a time, beating well after each addition, until all of the butter has been added. Continue to beat until mixture looks smooth. Fold in the melted chocolate and the hazelnut extract and beat until fluffy.
• To assemble the cake, split each cake layer horizontally in half to make 4 separate layers. Spread equal amounts of the hazelnut filling between each layer and frost top and sides of cake with the buttercream. To garnish, press chopped hazelnuts onto the sides of the cake. Using a pastry bag fitted with a star tip, pipe rosettes around the top rim using remaining frosting. Place whole hazelnuts and chocolate curls on the top of the cake.
• Tip: To make this cake an easier undertaking, take the time to search out hazelnuts that have already been peeled. If peeled nuts are unavailable, working in batches, boil nuts in 2 cups water along with 2 tablespoons baking soda for 1 to 2 minutes.
• Run nuts under water and slip off skins. Dry the nuts well and toast on a baking sheet in a 350 degree F oven for 20 minutes, stirring occasionally. Cool and finely chop and proceed with recipe. If you purchase the nuts already peeled, toast in a 350 degree F oven for only 15 minutes.

ESPRESSO-INFUSED POURED CHOCOLATE GANACHE

Steps:

• Place your chopped chocolate in the bowl of your stand mixer.
• Place the espresso beans in a sealable gallon-size bag (or between two pieces of parchment) and crush them with a rolling pin. Combine the heavy cream and espresso beans in a small pot and heat over medium-low heat until simmering. Remove from the heat, cover the pot and allow the cream to infuse for 10 minutes. Strain the cream through a cheesecloth-lined sieve into a clean pot. Return the cream to medium-low heat and bring back to a simmer.
• Pour the warm cream into the bowl of chocolate. Add the coffee liqueur if using and the salt. Gently stir the mixture with a spatula until smooth. At this point you can pour your ganache or you can cover and store in the refrigerator until ready to use. To reheat, gently heat in the microwave in 20 second bursts, stirring frequently, until fluid again.
