  • 2 cups all-purpose flour
  • 2 cups granulated sugar
  • 3/4 cup unsweetened cocoa powder
  • 1 1/2 teaspoons baking powder
  • 1 1/2 teaspoons baking soda
  • 1 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
  • 4 cups powdered sugar
  • 1/4 cup milk
  • 1 teaspoon vanilla extract


  1. Preheat the oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
  2. In a large mixing bowl, combine flour, sugar, cocoa powder, baking powder, baking soda, and salt.
  3. Add eggs, milk, oil, and vanilla extract to the dry ingredients. Beat on medium speed until well combined.
  4. Reduce the speed to low and add boiling water. Mix until the batter is smooth.
  5. Pour the batter evenly into the prepared cake pans. Bake for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean.
  6. Remove the cakes from the oven and let them cool in the pans for 10 minutes. Then, transfer them to wire racks to cool completely.
  7. In a mixing bowl, beat peanut butter and softened butter until creamy. Gradually add powdered sugar, milk, and vanilla extract. Beat until smooth and fluffy.
  8. Place one cake layer on a serving plate and spread a generous amount of peanut butter frosting on top. Place the second cake layer on top and cover the entire cake with the remaining frosting.
  9. Decorate the cake as desired and refrigerate for at least 1 hour before serving.
  10. Slice and enjoy the heavenly combination of peanut butter and chocolate in every bite!
