Indulge in the decadent fusion of rich chocolate and creamy peanut butter with this irresistible cake recipe.


  • 1 and 3/4 cups all-purpose flour
  • 3/4 cup unsweetened cocoa powder
  • 2 cups granulated sugar
  • 2 teaspoons baking powder
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 2 large eggs
  • 1 cup milk
  • 1/2 cup vegetable oil
  • 2 teaspoons vanilla extract
  • 1 cup boiling water
  • 1 cup creamy peanut butter
  • 1/2 cup unsalted butter, softened
  • 2 cups powdered sugar
  • 2-3 tablespoons heavy cream
  • 1 teaspoon vanilla extract


  1. Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
  2. In a large mixing bowl, sift together the flour, cocoa powder, sugar, baking powder, baking soda, and salt.
  3. Add eggs, milk, oil, and vanilla extract to the dry ingredients. Beat on medium speed for 2 minutes.
  4. Stir in the boiling water until the batter is well combined. It will be thin, but that’s okay.
  5. Pour the batter evenly into the prepared cake pans.
  6. Bake for 30 to 35 minutes or until a toothpick inserted into the center comes out clean.
  7. Remove the cakes from the oven and let them cool in the pans for 10 minutes. Then transfer them to a wire rack to cool completely.
  8. While the cakes are cooling, prepare the peanut butter frosting. In a mixing bowl, beat together the peanut butter and softened butter until smooth.
  9. Gradually add powdered sugar, heavy cream, and vanilla extract, beating until creamy and smooth. Adjust the consistency with more cream if needed.
  10. Once the cakes are completely cooled, place one layer on a serving plate. Spread a layer of peanut butter frosting evenly over the top.
  11. Carefully place the second cake layer on top and frost the top and sides of the cake with the remaining frosting.
  12. Decorate with chocolate shavings, chopped peanuts, or additional drizzles of peanut butter if desired.
  13. Slice and serve this heavenly chocolate peanut butter cake to delight your taste buds!
