How To Make Chocolate Peanut Butter Cake

Step 1: Preheat Oven and Prepare Pans – Preheat your oven to 350 degrees for aluminum or glass pans or 325 degrees for nonstick pans. Grease the sides of your pans and line the bottom of your pans with parchment paper. The parchment paper will ensure a quick and clean release from the pan after baking. Be sure to reference the temperature that is specified on your cake mix box.

Step 2: Mix the Chocolate Cake Batter – In a large mixing bowl, combine the chocolate cake mix, eggs, butter, milk, and vanilla. Mix for 2 minutes on medium speed. When all ingredients are fully incorporated and the batter is smooth its ready to pour. Evenly pour the batter into prepared pans.

Step 3: Bake the Cakes – Bake the cakes according to the instructions on the cake mix box, or until a toothpick inserted into the center comes out clean. The internal temperature of the cake should be between 200 degrees F and 210 degrees F.

Step 4: Cool the Cakes – Allow the cakes to cool for 10 minutes before removing cake and placing on a cooling rack. Once the cakes are completely cool, wrap in plastic wrap and place in the freezer for at least a few hours, if not overnight.

How To Make Frosting For Chocolate Peanut Butter Cake

Step 5: Prepare Peanut Butter Buttercream Frosting – To prepare the peanut butter buttercream frosting, beat the softened butter and creamy peanut butter together in a large bowl until smooth and fluffy. Gradually add the powdered sugar, one cup at a time, beating well after each addition.

Step 6: Pour in Milk – Pour in the milk one tablespoon at a time. Adding too much milk will cause a thin or runny frosting. If you don’t add enough milk it will be too stiff and won’t stick to your cake. Continue to beat the frosting for 3 minutes, until it reaches a creamy consistency and is workable.

Step 7: Decorate – Remove the cakes from the freezer, unwrap and remove the parchment paper from the bottom of the cakes. Spread a layer of peanut butter buttercream on top of one of the cakes. Place the second cake on top, creating a two-layer cake. Frost the entire cake with the remaining peanut butter buttercream, ensuring an even and smooth layer.

Step 8: Add Chocolate Shavings – For the finishing touch, generously sprinkle chocolate shavings over the top of the cake. Allow the frosted cake to thaw for about an hour then slice and serve this decadent Chocolate Peanut Butter Cake to your eager guests, and watch as it disappears in no time.
