Chocolate Peanut Butter Layer Cake Recipes

Steps:

• Pulse 4 peanut butter cups in a food processor into small chunks; transfer to a bowl. Pulse the remaining 6 peanut butter cups into a fine powder; transfer to another bowl. Chill both until ready to use.
• Preheat the oven to 350 degrees F. Grease four 8-inch round cake pans with cooking spray. Dust flour and knock out any excess. Set aside.
• In a medium bowl, sift together the flour, baking powder and salt.
• Cut up the butter into 1-inch pieces and place them in the large bowl of an electric mixer fitted with a paddle attachment or beaters. Beat on medium-high speed until the butter is light and creamy in color, about 3 minutes. Stop and scrape the bowl. Cream the butter for an additional minute. Add the granulated sugar, 1/4 cup at a time, beating 1 minute after each addition. Scrape the sides of the bowl occasionally. Add the eggs one at a time. Reduce the mixer speed. Stir the vanilla into the buttermilk. Add the dry ingredients to the butter alternately with the buttermilk. Mix just until incorporated. Scrape the sides of the bowl and mix for 15 seconds longer.
• Divide half the batter between the prepared cake pans. Set the remaining batter aside. Using the back of a spoon, spread out the batter so that it covers the bottom of each pan, making it slightly thicker around the edges than in the middle. Bake until cooked through and golden around the edges, 12 to 14 minutes. Set aside to let cool slightly, then loosen the cake layers with a knife and invert onto cooling racks.
• Wash and dry the cake pans. Repeat the process a second time with the cooking spray, flour and batter.
• Once all 8 layers have baked, place the first layer on a serving plate. Spread with about 3 tablespoons Chocolate Frosting and sprinkle with about 1 tablespoon powdered peanut butter cups. Top with another cake layer and repeat the process to make 8 layers in all. Frost the outside of the cake with the remaining frosting and sprinkle the top with the peanut butter cup chunks.
• In a large saucepot over medium-high heat, bring the milk to a simmer, and then remove from the heat.
• In a large mixing bowl, whisk together the yolks, flour, 1/3 cup confectioners' sugar and a pinch of salt. Add the hot milk in a stream, whisking. Return the mixture to the saucepot and bring to a boil over moderate heat. Whisk until very thick, about 3 minutes. Transfer to a large bowl. Cover the surface of the custard with a buttered round of wax paper and cool completely, about 45 minutes.
• Using electric beater, add the vanilla and remaining 1 cup confectioners' sugar to the custard. Beat at moderate speed until well combined. Then increase the speed to medium-high and beat in the butter, 2 tablespoons at a time, until smooth. Add the chocolates and beat until well combined.

Steps:

• Preheat the oven to 350 degrees F (175 degrees C). Grease and flour three 8-inch cake pans.
• Mix sugar, oil, sour cream, cocoa powder, eggs, vinegar, vanilla, and salt together in a mixing bowl. Add flour and water in batches, mixing and alternating between each, until incorporated. Whisk to create a smooth batter. Pour evenly into the prepared cake pans.
• Bake in the preheated oven until a toothpick inserted into the center of each layer comes out clean, about 30 minutes. Cool on a wire rack for 5 minutes. Run a table knife around the edges to loosen. Invert carefully onto a serving plate or cooling rack. Let cool, about 30 minutes.
• Combine cream cheese and butter for frosting in a very large mixing bowl with an electric mixer. Slowly add confectioners' sugar a few cups at a time until smooth. Mix in peanut butter to incorporate thoroughly.
• Generously distribute the frosting between the layers of the cake and on the top and sides. This frosting is a bit firm and easy to work with. At this point, place the cake in the refrigerator for at least 1 hour to set; it will be extremely heavy.
• Microwave chocolate, peanut butter, and corn syrup for glaze together in short 30-second intervals, mixing between each, until the chocolate is melted. Whisk in half-and-half until smooth. While warm, drizzle over the frosted cake.
• Place the cake back into the refrigerator to set, about 30 minutes. Remove the cake from the refrigerator 30 minutes to 1 hour before serving.

Steps:

• Preheat the oven to 350 degrees F (175 degrees C). Grease and line two 9-inch round cake pans with parchment paper.
• Beat butter and peanut butter for cake together with an electric mixer at medium speed until blended; gradually add brown sugar, beating well. Add eggs, one at a time, beating after each egg.
• Combine flour, baking powder, and salt in a bowl; add to peanut butter mixture alternately with milk, beginning and ending with flour mixture. Mix at low speed after each addition until blended. Stir in vanilla extract. Pour batter evenly between the prepared cake pans.
• Bake in the preheated oven until a toothpick inserted into the center of each cake comes out clean, 30 to 35 minutes. Remove from the oven and cool completely on a wire rack.
• While cakes cool, place unsweetened and semisweet chocolate in the top of a double boiler; bring water to a simmer and cook until chocolate melts, stirring often, 3 to 5 minutes. Remove from heat.
• Beat 1 cup butter with an electric mixer at medium speed until creamy. Add melted chocolate, powdered sugar, cocoa powder, milk, and vanilla extract; beat until spreading consistency.
• Place peanut butter and 1/2 cup butter in a small bowl. Beat with electric mixer at medium speed until creamy. Add powdered sugar gradually, alternately with milk, until frosting is thick and spreadable. Beat an additional 3 minutes.
• Remove 1 cooled cake layer from its pan and frost with chocolate buttercream frosting. Place second cake on top and complete frosting with chocolate buttercream.
• Frost a thick line on the top and bottom edges of the cake with peanut butter frosting using a frosting pouch fitted with a cake decorating tip. Place 16 dollops of peanut butter frosting around the perimeter of the cake. Place mini peanut butter cups on each dollop. Serve immediately.
