Ingredients
Scale
- Chocolate Cake:
- 1 3/4 cups all-purpose flour
- 3/4 cup unsweetened cocoa powder
- 2 cups granulated sugar
- 2 teaspoons baking soda
- 1 teaspoon baking powder
- 1 teaspoon salt
- 2 large eggs
- 1 cup buttermilk
- 1/2 cup vegetable oil
- 2 teaspoons vanilla extract
- 1 cup hot coffee or hot water
- Peanut Butter Frosting:
- 1 cup unsalted butter, softened
- 1 cup creamy peanut butter
- 3 cups powdered sugar
- 1 teaspoon vanilla extract
- 3–4 tablespoons heavy cream or milk
- 1/4 teaspoon salt
- Topping:
- 1/2 cup chocolate cake crumbs
Instructions
- Preheat oven to 350°F.
- Grease and line two 9-inch round cake pans with parchment paper.
- In a large mixing bowl, whisk together flour, cocoa powder, sugar, baking soda, baking powder, and salt.
- Add eggs, buttermilk, vegetable oil, and vanilla extract. Mix until smooth.
- Slowly pour in the hot coffee or hot water and mix until the batter is thin and well combined.
- Divide the batter evenly between the prepared cake pans.
- Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.
- Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
- To make the frosting, beat softened butter and peanut butter together until creamy and smooth.
- Add powdered sugar, vanilla extract, heavy cream, and salt. Beat until fluffy, adding more cream if needed for a spreadable texture.
- Place one cooled chocolate cake layer on a serving plate. Spread a thick layer of peanut butter frosting over the top.
- Add the second cake layer and frost the top with more peanut butter frosting.
- Sprinkle chocolate cake crumbs over the frosting.
- Slice and serve.
Notes
- Use room-temperature ingredients for best results.
- Hot coffee enhances the chocolate flavor, but hot water can be substituted.
- Adjust frosting consistency with more cream or powdered sugar as needed.
- Store leftovers in an airtight container at room temperature for up to 3 days.
