• ¾ cup unsweetened cocoa powder
• 2 cups granulated sugar
• 2 eggs
• 1 cup buttermilk
• ½ cup vegetable oil
• 1 cup hot coffee (enhances chocolate flavor)

How to Make Chocolate Peanut Butter Cake

Step 1: Prepare the Cake Batter

Preheat the oven to 350°F (175°C). Grease and line two 8-inch cake pans.

In a large bowl, whisk flour, cocoa powder, sugar, baking powder, baking soda, and salt.

Add eggs, buttermilk, oil, and vanilla. Mix until smooth.

Slowly pour in hot coffee and mix gently. The batter will be thin — that’s normal.

Pour evenly into prepared pans.

Bake for 30–35 minutes or until a toothpick comes out clean.

Cool completely before frosting.

Step 2: Make the Peanut Butter Frosting

Beat butter and peanut butter until creamy.

Gradually add powdered sugar.

Add cream and vanilla, then beat until light and fluffy.

If too thick, add a tablespoon of cream. If too soft, chill slightly.

Step 3: Prepare the Ganache

Heat cream until just simmering.

Pour over chocolate chips and let sit for 2 minutes.

Stir until smooth and glossy.

Let cool slightly before pouring.

Assembling the Cake

1. Place the first cake layer on a plate.
   
2. Spread a thick layer of peanut butter frosting.
   
3. Add a second cake layer.
   
4. Frost the entire cake smoothly.
   
5. Pour ganache over top, letting it drip down the sides.
   
6. Decorate with peanut butter cups or chopped peanuts if desired.

Chill 20–30 minutes before slicing for clean layers.

Tips for the Best Results

• Use room temperature ingredients
• Do not overmix batter
• Use hot coffee for deeper flavor
• Chill between layers if frosting becomes soft
• Slice with a warm knife for perfect presentation

Storage Tips

Refrigerate up to 4 days in an airtight container.

Bring to room temperature before serving for the creamiest texture.

You can freeze unfrosted cake layers for up to 2 months.

Variations to Try

• Add crushed peanut butter cups between layers
• Use dark chocolate ganache for intense flavor
• Add a sprinkle of sea salt on top
• Make as cupcakes for easy serving
