TIRAMISU LAYER CAKE RECIPES

Steps:

• Preheat oven to 350 degrees F (175 degrees C). Grease and flour 3 (9 inch) pans.
• Prepare the cake mix according to package directions. Divide two thirds of batter between 2 pans. Stir instant coffee into remaining batter; pour into remaining pan.
• Bake in the preheated oven for 20 to 25 minutes, or until a toothpick inserted into the center of the cake comes out clean. Let cool in pan for 10 minutes, then turn out onto a wire rack and cool completely. In a measuring cup, combine brewed coffee and 1 tablespoon coffee liqueur; set aside.
• To make the filling: In a small bowl, using an electric mixer set on low speed, combine mascarpone, 1/2 cup confectioners' sugar and 2 tablespoons coffee liqueur; beat just until smooth. Cover with plastic wrap and refrigerate.
• To make the frosting: In a medium bowl, using an electric mixer set on medium-high speed, beat the cream, 1/4 cup confectioners' sugar and 2 tablespoons coffee liqueur until stiff. Fold 1/2 cup of cream mixture into filling mixture.
• To assemble the cake: Place one plain cake layer on a serving plate. Using a thin skewer, poke holes in cake, about 1 inch apart. Pour one third of reserved coffee mixture over cake, then spread with half of the filling mixture. Top with coffee-flavored cake layer; poke holes in cake. Pour another third of the coffee mixture over the second layer and spread with the remaining filling. Top with remaining cake layer; poke holes in cake. Pour remaining coffee mixture on top. Spread sides and top of cake with frosting. Place cocoa in a sieve and lightly dust top of cake. Garnish with chocolate curls. Refrigerate at least 30 minutes before serving.
• To make the chocolate curls, use a vegetable peeler and run it down the edge of the chocolate bar.

Steps:

• Make the cake: Preheat the oven to 325 degrees F. Butter the bottoms and sides of two 9-inch round cake pans; line the bottoms with parchment paper. Butter the parchment and dust the bottom and side of each pan with flour, tapping out the excess. Whisk the flour, baking powder and salt in a medium bowl; set aside.
• Beat the butter in a large bowl with a mixer on medium-high speed until creamy, about 1 minute. Add the granulated sugar and continue beating until light and fluffy, about 4 minutes. Beat in the eggs one at a time until incorporated, then beat in the vanilla. Reduce the mixer speed to low and beat in the flour mixture in three batches, alternating with the milk in two batches, until just incorporated. Increase the speed to medium high and beat until smooth, about 30 seconds.
• Divide the batter between the prepared pans and lightly tap each against the counter to remove any air bubbles. Bake until lightly golden and a toothpick inserted into the centers comes out clean, 30 to 35 minutes. Let cool 15 minutes in the pans, then turn out onto a rack to cool completely; discard the parchment.
• Meanwhile, make the filling: Beat the cream cheese and coffee extract in a large bowl with a mixer on medium-high speed until smooth and creamy, about 1 minute. If using a stand mixer, switch to the whisk attachment. Add 1 1/2 cups heavy cream and the confectioners' sugar and beat until stiff peaks form, 2 to 3 minutes. Divide the filling between 2 small bowls (about 1 heaping cup each). Stir together the remaining 1 tablespoon heavy cream and the espresso powder in a small bowl to make a paste; fold into one bowl of filling. Fold the cocoa powder into the other bowl of filling. Refrigerate until ready to use.
• Make the frosting: Beat the butter and cream cheese in a large bowl with a mixer on medium-high speed until smooth, about 2 minutes. Reduce the mixer speed to low and beat in the confectioners' sugar, 1 teaspoon coffee extract, the vanilla and salt until just combined. Increase the mixer speed to medium high and beat until fluffy, about 4 more minutes; set aside.
• Make the ganache: Put the chocolate in a small bowl. Heat the heavy cream in a small saucepan until steaming, then pour over the chocolate. Let sit 5 minutes, then stir until melted and smooth. Stir in the remaining 1/2 teaspoon coffee extract; let sit until cool but still pourable, about 1 hour.
• Assemble the cake: Using a long serrated knife, carefully slice each cake in half horizontally to make 2 thin layers; brush the cut sides of each cake with coffee liqueur, if desired. Put 1 cake layer cut-side up on a plate and spread with 1 heaping cup frosting. Top with another cake layer and spread the coffee filling over the top. Top with another cake layer and spread with the cocoa filling. Top with the remaining cake layer. Frost the top and side of the cake with the remaining frosting. Pour the ganache over the top and gently spread with an offset spatula, letting it drip down the side. (If the ganache is too thick to pour, microwave in 10-second intervals until smooth.) Let set about 20 minutes before slicing.
