Milk or Cream: 2–4 tablespoons (for frosting), used to adjust consistency.
Instructions
Preheat Your Equipment: Preheat the oven to 350°F (175°C). Grease and line two 8-inch round cake pans with parchment paper.
Combine Ingredients: In a large bowl, sift together flour, sugar, cocoa powder, baking powder, baking soda, and salt. In another bowl, whisk eggs, buttermilk, oil, and vanilla. Combine wet and dry ingredients. Stir in boiling water slowly until smooth.
Prepare Your Cooking Vessel: Divide the batter evenly between the prepared pans. Tap pans gently on the counter to remove air bubbles.
Assemble the Dish: Bake for 30–35 minutes until a toothpick comes out clean. Let cakes cool in pans for 10 minutes, then transfer to wire racks.
Cook to Perfection: While cakes cool, make the frosting. Beat peanut butter and butter until fluffy. Gradually add powdered sugar, then milk or cream to desired consistency.
Finishing Touches: Once cakes are fully cooled, spread a thick layer of frosting between the layers and over the top and sides. Smooth with an offset spatula.
Serve and Enjoy: Slice generously and serve with a glass of cold milk or hot coffee. Savor every bite!
Notes
Use hot coffee instead of water for deeper chocolate flavor.
Chill the frosted cake before slicing for cleaner cuts.
Wrap cake layers and freeze for make-ahead ease.
Add chocolate chips to batter for extra indulgence.
