Ingredients You Will Need

To make the Chocolate Peanut Butter Layer Cake, gather the following ingredients:

For the Cake Layers:

  • 2 cups all-purpose flour
  • 2 cups granulated sugar
  • 3/4 cup unsweetened cocoa powder
  • 2 teaspoons baking powder
  • 1 1/2 teaspoons baking soda
  • 1 teaspoon salt
  • 1 cup whole milk
  • 1/2 cup vegetable oil
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 1 cup boiling water

For the Peanut Butter Filling:

  • 1 cup creamy peanut butter
  • 1/2 cup unsalted butter, softened
  • 2 cups powdered sugar
  • 1/4 cup heavy cream

For the Chocolate Ganache:

  • 1 cup semi-sweet chocolate chips
  • 1/2 cup heavy cream

Preparing the Cake Layers

Step 1: Preheat and Prepare

Begin by preheating your oven to 350°F (175°C). Grease and line two 9-inch round cake pans with parchment paper to prevent sticking. This recipe is perfect for beginners, so don’t worry if you haven’t baked a cake from scratch before!

Step 2: Mix Dry Ingredients

In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, unsweetened cocoa powder, baking powder, baking soda, and salt. Combining these dry ingredients thoroughly ensures an even mix before adding the wet ingredients.

Step 3: Add Wet Ingredients

Next, add the whole milk, vegetable oil, eggs, and vanilla extract to your dry mixture. Mix until the batter is smooth. The key to a great layer cake is to make sure your batter is well combined. Then, stir in the boiling water. The batter will be thin, but that’s perfectly fine!

Step 4: Bake the Cakes

Divide the batter evenly between the two prepared cake pans. Bake in the preheated oven for 30-35 minutes or until a toothpick inserted in the center comes out clean. Allow the cakes to cool completely in the pans before transferring them to a wire rack.

Preparing the Peanut Butter Filling

Step 5: Make the Filling

While the cakes are cooling, prepare the peanut butter filling. In a medium bowl, beat together the creamy peanut butter and softened unsalted butter until they are smooth and well combined. Gradually add the powdered sugar and heavy cream until the mixture is fluffy and spreadable. This step adds a delightful creaminess to the cake.

Making the Chocolate Ganache

Step 6: Prepare the Ganache

For the chocolate ganache, heat the heavy cream in a small saucepan until it is steaming, but not boiling. Remove from heat and add in the semi-sweet chocolate chips. Let the mixture sit for about 5 minutes, then stir until smooth. The ganache should be glossy and rich, perfect for drizzling over your cake.

Assembling Your Layer Cake

Step 7: Put It All Together

Now it’s time to assemble your masterpiece! Place one cake layer on a serving plate and spread a generous amount of peanut butter filling on top. Place the second cake layer on top and pour the chocolate ganache over the entire cake, letting it drip down the sides. For an extra touch, you can sprinkle some crushed peanuts on top.
