Capitol Grade Dark Chocolate Cake


For the cake

  • 2 cups all-purpose flour
  • 2 cups white sugar
  • 1 cup fine-quality unsweetened cocoa powder
  • 2 teaspoons baking soda
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 2 eggs
  • 1 cup coffee, cold-brewed
  • 1 cup buttermilk
  • 1/2 cup vegetable oil

For the icing

  • 2 cups butter, softened
  • 9 cups confectioners’ sugar
  • 2 1/2 cups fine-quality unsweetened cocoa powder
  • 1 teaspoon vanilla extract
  • 1 cup milk


Prep Time: 20 mins |  Ready In: 1 hour  |  Servings: 8

  1. Preheat oven to 350°F. Grease and flour a 9″ x 13″ pan.
  2. In a large bowl, sift together the flour, sugar, cocoa, baking soda, baking powder and salt. Make a well in the center and pour in the eggs, coffee, buttermilk and oil. Mix with a wooden spoon until smooth; batter will be thin. Pour into prepared pan.
  3. Bake for 35–40 minutes, or until a toothpick inserted into the center of the cake comes out clean. Allow to cool in the pan for 45 minutes.
  4. While cake cools, prepare the icing. In a stand mixer with a paddle attachment on medium speed or using a wooden spoon and lots of muscle, beat butter until smooth and creamy. Reduce speed to low and add confectioners’ sugar, cocoa, and vanilla, scraping down sides of the bowl with a spatula as you go. Add milk as needed until frosting reaches preferred spreading consistency. (For thicker frosting, add less than a cup of milk. To thin out your frosting, add more milk. The choice is yours!)
  5. Once cake has thoroughly cooled, spread icing over the top.
