How to Cook Chocolate Peanut Butter Cake: A Step-by-Step Guide
Step 1: Preheat the Oven and Prepare Pans
- Preheat your oven to 350°F (175°C).
- Grease and flour two 9-inch round cake pans. You can also line the bottoms with parchment paper for easier removal.
Step 2: Prepare the Chocolate Cake Batter
- In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
- In another bowl, combine the eggs, milk, vegetable oil, and vanilla extract. Add this wet mixture to the dry ingredients and mix until well-combined.
- Carefully pour in the boiling water, mixing slowly to avoid splashes. The batter will be thin, but that’s normal—it results in a moist cake.
Step 3: Bake the Cakes
- Divide the batter evenly between the prepared cake pans.
- Bake for 30–35 minutes or until a toothpick inserted into the center comes out clean.
- Remove from the oven and allow the cakes to cool in the pans for about 10 minutes before transferring them to wire racks to cool completely.
Step 4: Make the Peanut Butter Frosting
- In a medium bowl, beat the peanut butter and softened butter together until smooth.
- Gradually add powdered sugar, mixing until fully incorporated.
- Add vanilla extract and milk as needed to reach a spreadable consistency.
Step 5: Prepare the Chocolate Ganache
- Place the chocolate chips in a heat-safe bowl.
- Heat the heavy cream in a small saucepan until it just begins to simmer. Pour over the chocolate chips and let sit for 5 minutes.
- Stir until smooth and creamy. Let the ganache cool slightly before pouring it over the cake.
Step 6: Assemble the Cake
- Place one layer of chocolate cake on a serving plate. Spread a generous layer of peanut butter frosting on top.
- Add the second cake layer and frost the top and sides with the remaining peanut butter frosting.
- Drizzle the cooled ganache over the cake, letting it drip down the sides for an elegant finish.
- For extra flair, garnish with chopped peanut butter cups on top.
Common Mistakes to Avoid
- Overmixing the Batter: This can lead to a tough cake. Mix just until ingredients are combined.
- Not Allowing the Cake to Cool Fully: Frosting a warm cake can cause the frosting to melt and slide off. Always wait until the cake is completely cool.
- Using Cold Ingredients: For best results, use room-temperature ingredients for the cake batter and frosting.
- Skipping the Parchment Paper: Parchment helps the cakes release easily from the pans, especially with a moist cake like this.
Serving and Presentation Tips
Presentation is key to making your Chocolate Peanut Butter Cake look as good as it tastes. Here are some serving tips and ideas.
How to Serve Chocolate Peanut Butter Cake
- Serve at Room Temperature: Let the cake sit out for about 15 minutes before serving to soften the frosting slightly.
- Slice with a Warm Knife: Dip a sharp knife in warm water, wipe it dry, and slice the cake for cleaner cuts.
- Pair with Ice Cream: A scoop of vanilla or chocolate ice cream goes wonderfully with this cake.
Presentation Ideas for Chocolate Peanut Butter Cake
- Drip Effect: Let the ganache drip naturally for a beautiful, rustic look.
- Garnish with Peanut Butter Cups: Chop peanut butter cups and sprinkle them on top for added texture.
- Pipe Frosting: Use a piping bag to add decorative swirls or borders with peanut butter frosting.
Chocolate Peanut Butter Cake Recipe Tips
- Make Ahead: The cake layers can be made a day in advance and stored in an airtight container. Assemble and frost just before serving.
- Room Temperature Ingredients: Ensure that butter and eggs are at room temperature for the best texture.
- Use High-Quality Cocoa: The quality of your cocoa powder will affect the flavor, so go for a high-quality unsweetened cocoa for richer taste.
- Adjust Ganache Consistency: If the ganache is too thick, add a splash more cream; if it’s too thin, let it cool a little longer before using.

Q: Can I freeze Chocolate Peanut Butter Cake?
