How to Make the Chocolate Peanut Butter Cake

Step 1: Bake the Chocolate Cake

  1. Preheat the oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
  2. In a large bowl, sift together the flour, cocoa powder, sugar, baking powder, baking soda, and salt.
  3. Add eggs, milk, oil, and vanilla. Beat on medium speed for 2 minutes.
  4. Stir in boiling water—don’t worry if the batter seems thin, it’s supposed to be!
  5. Divide the batter evenly between the pans and bake for 30-35 minutes, or until a toothpick inserted comes out clean.
  6. Let the cakes cool completely before assembling.

Step 2: Make the Peanut Butter Frosting

  1. In a bowl, beat peanut butter and softened butter together until creamy.
  2. Gradually add powdered sugar, alternating with heavy cream, until you achieve a fluffy and smooth frosting.
  3. Add vanilla extract and mix until fully incorporated.

Step 3: Prepare the Chocolate Ganache

  1. Heat heavy cream in a small saucepan over medium heat until it just starts to simmer.
  2. Pour the hot cream over the chocolate chips in a bowl and let it sit for 5 minutes.
  3. Whisk the mixture until smooth and glossy. Let it cool slightly before pouring over the cake.

Step 4: Assemble the Cake

  1. Place one layer of the cooled chocolate cake on a serving plate and spread a generous layer of peanut butter frosting over the top.
  2. Add the second layer of cake, then frost the entire cake with the remaining peanut butter frosting.
  3. Pour the chocolate ganache over the top of the cake, letting it drip naturally down the sides for a gorgeous finish.
  4. Allow the cake to chill for 30 minutes before serving, giving the ganache time to set.

Tips for the Best Chocolate Peanut Butter Cake

  • Room temperature ingredients: Make sure your eggs, butter, and cream are at room temperature to ensure smooth mixing and a fluffy cake.
  • Boiling water: Stirring boiling water into the batter is the secret to a super moist chocolate cake!
  • Garnish galore: For an extra indulgent touch, garnish with chopped peanuts or crushed peanut butter cups. It adds texture and makes the cake look even more tempting!

Serving Suggestions

This cake pairs beautifully with a cold glass of milk or a hot cup of coffee. If you’re feeling fancy, a scoop of vanilla ice cream on the side is heavenly!

Storage Instructions

  • Refrigerate leftovers: Store any leftover cake in an airtight container in the refrigerator for up to 5 days.
  • Bring to room temperature: Allow the cake to come to room temperature before serving to enjoy the soft frosting and cake texture.

Frequently Asked Questions

Can I use natural peanut butter in the frosting?
