FOOD NETWORK FLOURLESS CHOCOLATE CAKE RECIPES

Steps:

• Preheat the oven to 350 degrees F. Butter two 8-inch x 2-inch round cake pans. Line with parchment paper, then butter and flour the pans.
• Sift the flour, sugar, cocoa, baking soda, baking powder, and salt into the bowl of an electric mixer fitted with a paddle attachment and mix on low speed until combined. In another bowl, combine the buttermilk, oil, eggs, and vanilla. With the mixer on low speed, slowly add the wet ingredients to the dry. With mixer still on low, add the coffee and stir just to combine, scraping the bottom of the bowl with a rubber spatula. Pour the batter into the prepared pans and bake for 35 to 40 minutes, until a cake tester comes out clean. Cool in the pans for 30 minutes, then turn them out onto a cooling rack and cool completely.
• Place 1 layer, flat side up, on a flat plate or cake pedestal. With a knife or offset spatula, spread the top with frosting. Place the second layer on top, rounded side up, and spread the frosting evenly on the top and sides of the cake.
• Chop the chocolate and place it in a heat-proof bowl set over a pan of simmering water. Stir until just melted and set aside until cooled to room temperature.
• In the bowl of an electric mixer fitted with a paddle attachment, beat the butter on medium-high speed until light yellow and fluffy, about 3 minutes. Add the egg yolk and vanilla and continue beating for 3 minutes. Turn the mixer to low, gradually add the confectioners' sugar, then beat at medium speed, scraping down the bowl as necessary, until smooth and creamy. Dissolve the coffee powder in 2 teaspoons of the hottest tap water. On low speed, add the chocolate and coffee to the butter mixture and mix until blended. Don't whip! Spread immediately on the cooled cake.

Steps:

• For the frosting: Put the chocolate in a large, heatproof bowl. Bring the cream to a boil in a medium saucepan over medium heat. Pour the hot cream over the chocolate and let it sit, undisturbed, for 10 minutes, then add the salt and stir until melted and combined. Refrigerate, in the bowl, until thick and very cold, about 2 hours. Whip with an electric mixer on medium-high until fluffy, spreadable and slightly lightened in color.
• For the cake: Preheat the oven to 350 degrees. Butter and flour two 9-inch cake pans. Line the bottom of each with parchment. 
• Combine the flour, cocoa powder, baking soda and baking powder in a medium bowl. Dissolve the instant espresso powder in 1 1/3 cups warm water.
• Beat together the sugar, vanilla and eggs in a large bowl with an electric mixer on medium-high speed until light and fluffy, about 3 minutes. Beat in the mayonnaise and the melted chocolate until just combined.
• Alternate beating the flour mixture and the espresso mixture on medium-high speed into the chocolate-egg mixture until just combined; work in 4 batches, beginning and ending with the flour mixture. Take care not to over mix. 
• Pour the cake batter into the prepared pans and bake until the cakes are set and the tops spring back when touched and a toothpick inserted into the center of the cakes comes out clean, about 30 minutes. Cool the cakes in the pans set on a rack for 20 minute. Invert the cakes onto the rack, remove the parchment paper and cool completely.
• Frost the cake: Put 1 cake round on a cake stand or large serving plate and evenly spread 3/4 cup frosting over it. Top with the other cake round. Frost the top and sides with the remaining frosting. The cake can be frosted up to a day in advance. Let sit at room temperature for 30 minutes before serving.
