  • Unsalted butter, softened, for pans
  • 3/4 cup unsweetened Dutch cocoa powder, plus more for pans
  • 1 1/2 cups all-purpose flour
  • 1 1/2 cups sugar
  • 1 1/2 teaspoons baking soda
  • 3/4 teaspoon baking powder
  • 3/4 teaspoon salt
  • 2 large eggs
  • 3/4 cup low-fat buttermilk
  • 3/4 cup warm water
  • 3 tablespoons safflower oil
  • 1 teaspoon pure vanilla extract
  • Chocolate Frosting


  1. Preheat oven to 350 degrees. Butter two 8-inch round cake pans (2 inches deep); dust with cocoa. Sift cocoa, flour, sugar, baking soda, baking powder, and salt into the bowl of a mixer. Beat on low speed until just combined. Raise speed to medium, and add eggs, buttermilk, water, oil, and vanilla. Beat until smooth, about 3 minutes.

  2. Divide batter between pans. Bake until set and a toothpick inserted into the centers comes out clean, about 35 minutes. Let cool for 15 minutes. Turn out from pans. Transfer, faceup, to wire racks. Let cool completely.

  3. Spread 2 cups chocolate frosting onto top of 1 cooled layer. Top with remaining layer; frost top and sides with remaining 2 cups frosting.
