Kitchen Equipment Needed
- Two 9-inch round cake pans
- Mixing bowls
- Electric mixer or whisk
- Spatula
- Saucepan
- Cooling rack
Ingredients Overview
- Cake Base: A blend of cocoa powder, sugar, and buttermilk makes for a rich and moist chocolate cake.
- Chocolate Frosting: Melted chocolate and butter create a velvety frosting that takes the cake to the next level.
Ingredients
For the Cake
- 2 cups granulated sugar
- 1 ¾ cups all-purpose flour
- ¾ cup unsweetened cocoa powder
- 2 teaspoons baking powder
- 1 ½ teaspoons baking soda
- 1 teaspoon salt
- 2 large eggs
- 1 cup buttermilk
- ½ cup vegetable oil
- 2 teaspoons vanilla extract
- 1 cup boiling water
For the Frosting
- 1 cup unsalted butter, softened
- 4 cups powdered sugar
- ¾ cup unsweetened cocoa powder
- 1 teaspoon vanilla extract
- ½ cup heavy cream (plus more if needed)
Step-by-Step Instructions
- Prepare the Cake Pans:
Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans, or line them with parchment paper.
- Mix the Dry Ingredients:
In a large mixing bowl, sift together sugar, flour, cocoa powder, baking powder, baking soda, and salt.
- Combine the Wet Ingredients:
Add the eggs, buttermilk, vegetable oil, and vanilla extract to the dry mixture. Beat on medium speed until well combined.
- Incorporate the Boiling Water:
Gradually stir in the boiling water (the batter will be thin). Mix until smooth.
- Bake the Cakes:
Divide the batter evenly between the prepared pans. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
- Make the Frosting:
Beat the softened butter until creamy. Add the powdered sugar, cocoa powder, and vanilla extract. Gradually add the heavy cream, beating until the frosting is smooth and spreadable.
- Assemble the Cake:
Place one cake layer on a serving plate. Spread a generous layer of frosting on top. Add the second cake layer and frost the top and sides.
- Serve:
Slice and serve with a glass of cold milk for the ultimate nostalgic experience.

Recipe Tips
- Substitute for Buttermilk: If you don’t have buttermilk, mix 1 cup of milk with 1 tablespoon of vinegar or lemon juice and let it sit for 5 minutes.
- Enhance the Chocolate Flavor: Add a teaspoon of espresso powder to the cake batter to deepen the chocolate taste.
- Frosting Consistency: If the frosting is too thick, add more heavy cream, a tablespoon at a time, until it reaches the desired consistency.
What to Serve With This Recipe
