Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

All-purpose flour provides structure while keeping the cake layers tender.

Cocoa powder gives the cake its deep chocolate flavor and rich color.

Granulated sugar sweetens the cake and contributes to a moist crumb.

Brown sugar adds moisture and enhances the chocolate flavor.

Baking powder and baking soda help the cake rise evenly and stay light.

Salt balances sweetness and intensifies both chocolate and peanut butter flavors.

Eggs bind the batter and contribute richness.

Vegetable oil keeps the cake moist and soft.

Milk adds moisture and creates a smooth batter.

Vanilla extract enhances overall flavor and aroma.

Creamy peanut butter forms the base of the frosting, delivering smooth texture and bold flavor.

Unsalted butter adds richness and structure to the frosting.

Powdered sugar sweetens and thickens the frosting.

Heavy cream helps create a light, spreadable frosting consistency.

Optional chocolate ganache can be used as a finishing drizzle or filling.

Directions

Begin by preheating the oven to 175°C and greasing two round cake pans. In a large bowl, whisk together the flour, cocoa powder, sugars, baking powder, baking soda, and salt. In a separate bowl, mix eggs, oil, milk, and vanilla extract until combined. Add the wet ingredients to the dry ingredients and mix until smooth. Divide the batter evenly between the prepared pans and bake until a toothpick inserted into the center comes out clean. Allow the cakes to cool completely. For the frosting, beat the butter and peanut butter until smooth, then gradually add powdered sugar and cream until light and fluffy. Assemble the cake by spreading frosting between the layers and over the top and sides. Finish with chocolate ganache or decorative swirls if desired.

Variations and Customizations

For a darker chocolate profile, espresso powder can be added to the batter to enhance cocoa flavor. If you prefer a lighter frosting, whipped peanut butter frosting works well and spreads easily. You can also swap the chocolate cake for a chocolate sponge for a slightly lighter version. Decorating the top with chocolate shavings or roasted peanuts adds visual appeal and crunch.
