Chocolate Tweed Layer Cake Recipes

Steps:

• Preheat oven to 400 degrees. Grease three 9-inch cake pans and line with rounds of parchment or waxed paper.
• In a mixer, cream together butter, sugar and shortening until fluffy, about 3 minutes. Beat in eggs one at a time and continue to mix on medium until eggs are well incorporated. Stir in vanilla.
• Sift flour, then add salt, baking soda and baking powder. Sift a second time. With mixer on low, alternately add flour mixture and milk in about 4 additions, then increase speed to medium. Beat until smooth, about 4 to 5 minutes, scraping down sides of bowl.
• Spread 3/4 cup batter in each pan. Bake 6 to 8 minutes, or until cake springs lightly when pressed with a finger. Flip cake out of pan onto paper towels or cake rack while still very warm. Repeat with second set of layers.
• When first layers go into oven, start to make icing. Put sugar and cocoa in a deep, heavy-bottomed saucepan and mix well. Turn heat to medium-high and add butter and milks, bringing to a boil. Boil for about 4 minutes, stirring continually, careful to watch that it does not boil over. Lower heat to simmer, add vanilla and stir occasionally for another 7 to 10 minutes. If using a candy thermometer, cook to the point just before soft ball stage or about 230 degrees.
• Begin icing first layers, still warm, when second batch is in the oven. Flip layers over so that top side faces up. Use about 4 tablespoons of icing per layer. Icing will be thin but will firm up as it cools. Stack layers, then continue icing and stacking as layers are baked.
• When all layers are iced and stacked, glaze top and sides of cake. Contours of layers will be visible through icing. If icing hardens too much while frosting cake, set back on low heat and stir until it is spreadable.

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.

Steps:

• Prep the pans: Preheat the oven to 350 degrees F. Fold a large sheet of parchment paper in half; put a 10-inch-round cake pan on top. Trace the cake pan, then cut out the circle to make two rounds of parchment. Spray two 10-inch cake pans with cooking spray; fit a parchment round into each. Spray the pans again, then dust with flour and tap out the excess.
• Make the batter: Pour the coffee into a liquid measuring cup or bowl; whisk in the cocoa powder. Put the flour, salt, baking soda, baking powder and sugar in the bowl of a stand mixer; mix with the paddle attachment on low speed, 1 minute. Add the eggs, vegetable oil, vanilla and 2 cups water; beat on medium speed, 2 minutes. Reduce the speed to low; beat in the coffee-cocoa mixture in a slow stream until combined. The batter will be thin.
• Bake the cakes: Divide the batter between the prepared pans. Bake until a skewer inserted into the middle comes out clean, 50 minutes to 1 hour. Let cool in the pans on a rack, 10 minutes, then turn the cakes out onto the rack to cool completely. Place each cake on a 10-inch cardboard cake circle (this helps stabilize the layers as you move them around), wrap in plastic wrap and refrigerate at least 4 hours or overnight.
• Make the ganache: Pulverize the bittersweet chocolate in a large food processor. Bring the cream just to a boil. With the motor running, pour the hot cream through the feed tube; process until smooth. Transfer to a large bowl and set in a bowl of ice water. Chill, stirring often, until the ganache is cool but not stiff, about 20 minutes.
• Make the bark: Microwave the white chocolate in 15-second intervals until two-thirds melted; stir to fully melt. Scrape into a zip-top bag and seal. Put a plastic sheet protector on each of 2 baking sheets. Snip a corner of the bag; pipe thin lines of white chocolate over the sheets.
• Refrigerate the baking sheets until the white chocolate is set, about 10 minutes, then repeat the process with the milk chocolate, piping thin lines over the white chocolate. Refrigerate until the milk chocolate is set.
• Melt the bittersweet chocolate in the same way, then spread over the white and milk chocolate lines using an offset spatula. Refrigerate until hard, about 30 minutes.
• Peel the sheet protectors off the chocolate and break the chocolate sheets into shards of various sizes.
• Slice the layers: Put one cake on a cake turntable. Position a long serrated knife against the side of the cake, about halfway down. Slowly rotate the turntable so the knife slices the cake in half horizontally. Don't move the knife much-let the rotation of the turntable do the work. Repeat with the other cake to make 4 layers; transfer each to a cardboard circle. (If you don't have a turntable, carefully slice the cakes in half on a cutting board.)
• Frost the cake: Transfer half of the ganache to a bowl and whisk until light brown and fluffy. Place one cake layer (still on a cardboard circle) on the turntable; spoon one-third of the whipped ganache on top. Rotate the turntable to smooth the ganache with a long spatula (or just assemble and frost on a cake plate). Repeat to sandwich all 4 cake layers with whipped ganache. Spread all but about 1/2 cup of the unwhipped ganache over the top and sides of the cake.
• Decorate the cake: Press the chocolate bark against the sides of the cake, using small dollops of the remaining ganache to help the pieces stick, if necessary.

Steps:

• Preheat oven to 350 degrees F (175 degrees C). Grease a 9x9-inch square cake pan.
• Beat egg whites in a glass or metal bowl until stiff peaks form. Lift your beater or whisk straight up: the egg whites will form sharp peaks.
• Beat unsalted butter and white sugar together in a large bowl with an electric mixer until light and fluffy; beat in flour, baking powder, and 1 teaspoon salt. Beat milk and 1 teaspoon vanilla extract into flour mixture; fold in beaten egg whites and chocolate chips. Spread batter into prepared pan.
• Bake in the preheated oven until a toothpick inserted into the center comes out clean, about 25 minutes. Cool completely in the pan on a wire rack, about 30 minutes.
• Beat 1/3 cup butter, confectioners' sugar, egg yolks, 1 teaspoon vanilla extract, and the pinch of salt together with an electric mixer until smooth; spread on the cooled cake.
• Melt chocolate squares with 2 tablespoons butter in a microwave-safe bowl, about 30 seconds on High. Allow chocolate mixture to cool slightly, then spread chocolate carefully over iced cake. Refrigerate cake until chocolate is set, about 30 minutes.
