CHOCOLATE CAKE MIX ADD INS 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:

• In the bowl of an electric mixer fitted with the whisk attachment, combine the heavy cream, mascarpone, sugar, coffee liqueur, cocoa powder, espresso powder, and vanilla. Mix on low speed to combine and then slowly raise the speed, until it forms firm peaks.
• To assemble the cake, arrange chocolate chip cookies flat in an 8-inch springform pan, covering the bottom as much as possible. (I break some cookies to fill in the spaces.) Spread a fifth of the mocha whipped cream evenly over the cookies. Place another layer of cookies on top, lying flat and touching, followed by another fifth of the cream. Continue layering cookies and cream until there are 5 layers of each, ending with a layer of cream. Smooth the top, cover with plastic wrap, and refrigerate overnight.
• Run a small sharp knife around the outside of the cake and remove the sides of the pan. Sprinkle the top with the chocolate, cut in wedges, and serve cold.
