For the frosting

  • 1/2 cup unsweetened cocoa powder Intensifies the chocolate flavor.
  • 1/4 cup heavy cream For a rich, smooth frosting texture.

Instructions

Preparation

  • Preheat the oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
  • In a large bowl, sift together the flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt.
  • Add the buttermilk, vegetable oil, eggs, and vanilla extract to the dry mixture. Beat on medium speed until smooth. Gradually stir in the boiling water.

Baking

  • Divide the batter evenly between the prepared pans. Bake for 30-35 minutes or until a toothpick comes out clean. Allow to cool for 10 minutes, then transfer to wire racks.

Frosting

  • Beat the softened butter until creamy. Gradually add the powdered sugar and cocoa powder on low speed. Add heavy cream and vanilla extract, and beat until fluffy.
  • Frost the cooled cakes and chill for 30 minutes before serving.

Notes

Ensure room temperature ingredients for best results. Sifting keeps the mixture lump-free. For a variation, you can add chocolate chips or spices.
