For the Cake:

  • 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 buttermilk, at room temperature
  • 1/2 cup vegetable oil
  • 2 large eggs, at room temperature
  • 2 teaspoons vanilla extract
  • 1 cup boiling water

For the Chocolate Frosting:

  • 1 cup unsalted butter, softened
  • 3 1/2 cups powdered sugar
  • 1/2 cup unsweetened cocoa powder
  • 1/2 cup heavy cream
  • 2 teaspoons vanilla extract
  • Pinch of salt


For the Cake:

  1. Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans, then line the bottoms with parchment paper.
  2. In a large mixing bowl, sift together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
  3. Add the buttermilk, vegetable oil, eggs, and vanilla extract to the dry ingredients. Beat on medium speed with an electric mixer until well combined.
  4. Reduce the mixer speed to low and carefully add the boiling water to the batter. Mix until smooth and well combined. The batter will be thin.
  5. Pour the batter evenly into the prepared cake pans.
  6. Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center of the cakes comes out clean.
  7. Remove the cakes from the oven and let them cool in the pans for 10 minutes. Then, transfer the cakes to a wire rack to cool completely.

For the Chocolate Frosting:

  1. In a large mixing bowl, beat the softened butter until creamy.
  2. Gradually add the powdered sugar and cocoa powder, beating on low speed until combined.
  3. Increase the mixer speed to medium and add the heavy cream, vanilla extract, and a pinch of salt. Beat until the frosting is smooth and fluffy, about 2-3 minutes. Add more cream if needed to reach the desired consistency.

Assembling the Cake:

  1. Once the cakes are completely cool, level the tops with a knife if necessary to create even layers.
  2. Place one cake layer on a serving plate or cake stand. Spread a generous amount of frosting over the top.
  3. Place the second cake layer on top and frost the top and sides of the cake with the remaining frosting.
  4. Smooth the frosting with a spatula and decorate as desired. You can add chocolate shavings, sprinkles, or fresh berries for an extra touch.
  5. Slice and serve your decadent chocolate layer cake. Enjoy!
