Do peanut butter and dark chocolate go together?

Absolutely. The bitterness of dark chocolate provides a sophisticated backdrop for the salty, creamy profile of peanut butter, creating a balanced and luxurious flavor profile.

What is the best peanut butter for cake frosting?

For the most stable and smooth frosting, use a processed creamy peanut butter like Jif or Skippy. Natural varieties often separate and can make the frosting greasy or unstable.

How do I make my chocolate cake very dark?

The darkness comes from using high-quality natural cocoa powder and incorporating hot coffee into the batter. The coffee blooms the cocoa, releasing its pigment and deepening the flavor without adding a coffee taste.

Can I make the cake layers in advance?

Yes, you can bake the layers, wrap them tightly in plastic wrap, and refrigerate them for up to two days. This actually makes the cake easier to trim and frost as the crumb becomes more stable.

Instructions

Preheat and prep. Preheat oven to 350°F (177°C) and grease three 9-inch cake pans with parchment paper lining.
Whisk dry ingredients. Combine flour, cocoa powder, sugar, baking soda, baking powder, and salt in a large bowl.
Emulsify wet ingredients. Beat oil, eggs, and sour cream on medium-high speed before adding the buttermilk and vanilla.
Combine the batter. Pour wet into dry with the hot coffee, whisking until combined, then fold in the flour-coated chocolate chips.
Bake the layers. Divide batter into pans and bake for 24–26 minutes, then cool completely on a wire rack.
Prepare the frosting. Cream the butter and peanut butter together, then gradually beat in sugar, salt, vanilla, and heavy cream until fluffy.
Assemble the cake. Stack layers with frosting between each, apply a thin crumb coat to the outside, and chill for 30 minutes.
Finish with ganache. Pour heated heavy cream over chopped chocolate, let sit for three minutes, stir until smooth, and drizzle over the chilled cake.

Notes

Ensure all refrigerated ingredients such as eggs and sour cream reach room temperature before starting to ensure a stable emulsion and a tender, even crumb. Using processed creamy peanut butter instead of natural varieties is essential for maintaining a stable frosting structure that holds up between the cake layers.
