Chocolate Cake with Chocolate Buttercream Frosting

If you are in the mood for a chocolate cake with the richest chocolate buttercream frosting, you just gotta make this. Bruce has been baking cakes from scratch for years, and this cake is the one that our son’s ask for. He uses dutch processed dark cocoa powder and espresso powder in the cake to give its rich flavor. Admittedly, I am not the biggest chocolate fan, and will always reach for a fruit dessert over chocolate cake. Well, except this chocolate cake. It is just so good.

Chocolate Cake with Chocolate Buttercream



Ingredients for Chocolate Cake:

  • 2 cups flour
  • 2 cups sugar
  • 3/4 cup dutch cocoa powder
  • 1 1/2 teaspoons baking soda
  • 2 teaspoons baking powder
  • 1 1/2 teaspoon espresso powder
  • 1 teaspoon salt
  • 1/2 cup vegetable oil
  • 2 large Pete and Gerrys eggs
  • 1 cup milk buttermilk
  • 2 teaspoons vanilla
  • 1 cup boiling water

Ingredients for Chocolate Buttercream:

  • cups butter, softened
  • 1 cup dutch processed dark unsweetened cocoa
  • 5 cups confectioner’s sugar
  • 1/4 cup heavy cream
  • 2 teaspoons vanilla
  • ½ teaspoon espresso powder


Instructions for the Chocolate Cake:

Preheat oven to 325º F.
Spray inside of 2 round 8 inch cake pans with baking spray. If you use parchment rounds, place in pan and spray the parchment as well.
Measure all dry ingredients into the bowl of a stand mixer. Mix dry ingredients with a whisk to blend.
Add buttermilk, vegetable oil, egg, and vanilla to dry mixture on medium speed until well combined.
Reduce speed and carefully add boiling water to the cake batter. Beat on high speed for about 1 minute to add air to the batter.
Pour half the batter into each pan. Bake for 25 minutes on the middle rack, turning pans half way. Test doneness by inserting a toothpick into the center of the cake. If it comes out clean, cake is done.
Allow cakes to cool in pans for 10 minutes.  At this point, remove cakes from pan and allow to cool completely on a wire rack.

Instructions for the Chocolate Buttercream:

While cake cools, make the buttercream frosting.
Add cocoa to bowl of stand mixer. Using a whisk or fork, get rid of any lumps.
Cream butter and cocoa powder until combined. Turn off mixer.
One cup at a time, add in the confectioner’s sugar and about a teaspoon of the cream. Slowly bring mixer up to speed to avoid the sugar from flying out of the bowl. Between each addition, bring up to fast speed to fully whip the frosting. Repeat until all the sugar and cream are added. Add vanilla extract and espresso powder and combine well.

At this point, check the consistency of the frosting. If too stiff, add a bit more of the cream, and beat until fluffy.

Assemble Chocolate Cake:

Using a serrated knife or cake leveler, remove the top rounded portion so that they are level. Place first cake on plate, add frosting and smooth out. Add next cake and frost top and sides.


Store cake in the refrigerator for up to a week. Remove for at least 30 minutes before serving. When slicing cake, use a sharp knife that has been heated under running hot water. Clean and re-warm knife for every cut.
