Ingredients

  • 1 lb butter
  • 2 1/3 cups granulated sugar
  • 2/3 cup dark brown sugar
  • 7 eggs
  • 6 ounces unsweetened chocolate
  • 4 1/2 cups pastry flour (or use 2/3 all-purpose flour and 1/3 cake flour)
  • 1 teaspoon baking powder
  • 2 teaspoons baking soda
  • 1 teaspoon salt
  • 2/3 cup cocoa
  • 2 teaspoons pure vanilla extract
  • 2 1/3 cups buttermilk

Method

  • Butter two 10-inch round layer cake pans and dust them with cocoa.
  • Or butter and line with parchment.
  • Preheat the oven to 350° F.
  • Cream together the butter, granulated sugar, and brown sugar.
  • Beat in the eggs, then melt the chocolate in a double boiler over simmering water and allow it to cool.
  • Sift together the flour, baking powder, baking soda, salt, and cocoa.
  • Add the vanilla to the buttermilk.
  • Add the cooled melted chocolate to the eggs and butter.
  • Then alternately mix in the dry ingredients and the buttermilk.
  • Fill your pans about half full with batter.
  • Bake in the preheated oven about 40 to 45 minutes.
  • Insert a straw or cake tester into the centers of layers.
  • If it comes out clean (i. e., without any batter sticking to it) the cake is done and should be removed from the oven.
  • The cakes can also be tested for doneness by pressing on them gently in the center.
  • If they have a slightly springy feel, they are ready to come out.
  • Cool and frost as desired.
