What is a Chocolate Peanut Butter Cake?
Chocolate Peanut Butter Cake is a decadent dessert featuring layers of moist chocolate cake paired with a creamy, sweet peanut butter frosting. This flavor combination is a favorite among dessert lovers, as the rich chocolate perfectly complements the nutty, slightly salty peanut butter. This homemade version ensures the freshest ingredients and allows you to customize the flavors to your liking.
Ingredients List for Chocolate Cake Layers
To make the chocolate cake layers, you’ll need the following ingredients:
- 2 cups all-purpose flour
- 2 cups granulated sugar
- ¾ cup unsweetened cocoa powder
- 2 teaspoon baking powder
- 1 ½ teaspoon baking soda
- 1 teaspoon salt
- 2 large eggs, room temperature
- 1 cup whole milk, room temperature
- ½ cup vegetable oil
- 2 teaspoon pure vanilla extract
- 1 cup boiling water
These ingredients form the base of a classic, moist chocolate cake. Boiling water helps to enhance the cocoa flavor, giving the cake a deeper, richer chocolate taste.
Ingredients List for Peanut Butter Frosting
For the rich and creamy peanut butter frosting, you’ll need:
- 1 cup creamy peanut butter (preferably no-stir)
- ½ cup unsalted butter, softened
- 3 cups powdered sugar, sifted
- ¼ cup heavy cream (add more if needed for consistency)
- 1 teaspoon pure vanilla extract
- Pinch of salt
This frosting is smooth, creamy, and absolutely delicious. Make sure the peanut butter you use is no-stir, as natural peanut butter can separate and affect the texture of the frosting.
Substitutions and Variations
If you’d like to adjust the recipe to suit your tastes or dietary needs, here are some substitutions and variations:
- Gluten-Free Option: Use a 1:1 gluten-free baking flour instead of all-purpose flour.
- Dairy-Free: Substitute almond milk or oat milk for whole milk in the cake, and use a dairy-free butter substitute in the frosting.
- Chocolate Variation: Add ½ cup of chocolate chips to the cake batter for a burst of chocolate in each bite.
- Peanut Butter Alternatives: Swap out peanut butter for almond butter or cashew butter if you prefer a different nut flavor.
- Add a Filling: Add a layer of chocolate ganache or caramel between the cake layers for an extra indulgent touch.
Step-by-Step Cooking Instructions

Ready to start baking? Follow these steps for a deliciously rich chocolate peanut butter cake.
Step 1: Prepare Your Baking Pans
Preheat your oven to 350°F (175°C). Grease and line two 9-inch round cake pans with parchment paper to prevent the cake from sticking.
Step 2: Mix the Dry Ingredients
In a large mixing bowl, sift together the flour, sugar, cocoa powder, baking powder, baking soda, and salt. Stir to combine all the dry ingredients evenly.
Step 3: Combine Wet Ingredients
In a separate bowl, whisk together the eggs, milk, oil, and vanilla extract until smooth.
Step 4: Mix the Batter
Gradually add the wet ingredients to the dry ingredients, stirring until combined. Then, carefully pour in the boiling water, stirring until the batter is smooth and thin.
Step 5: Bake the Cakes
Divide the batter evenly between the two prepared cake pans. Bake for 30-35 minutes or until a toothpick inserted into the center comes out clean. Allow the cakes to cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely.
Step 6: Prepare the Peanut Butter Frosting
While the cakes are cooling, beat the peanut butter and softened butter together until smooth. Gradually add the powdered sugar and beat until fluffy. Add the heavy cream, vanilla extract, and salt, mixing until the frosting reaches a creamy consistency.
How to Cook Chocolate Peanut Butter Cake: A Step-by-Step Guide
This cake recipe is straightforward but has a few key steps to get the best results.
- Prepare the cake batter: Follow the instructions carefully, ensuring the batter is well-mixed but not over-stirred.
- Bake evenly: Place your cake pans on the center rack to ensure even baking. Don’t open the oven door too often, as this can cause the cake to sink.
- Cool completely: Let the cakes cool before frosting, as warm cakes will melt the frosting and ruin the texture.
- Frost with patience: Apply a thin “crumb coat” of frosting to seal in crumbs, then add a final layer of frosting for a smooth finish.
Common Mistakes to Avoid
- Overmixing the batter: Overmixing can make the cake dense and chewy. Mix until just combined for a soft, moist texture.
- Using cold ingredients: Ensure eggs, milk, and other ingredients are at room temperature for smoother blending and better texture.
- Frosting too soon: Frosting a warm cake will melt the frosting, creating a messy and runny appearance. Always cool cakes fully before frosting.
- Skipping the crumb coat: A thin layer of frosting (crumb coat) before the final layer will make for a cleaner, more professional-looking cake.
Serving and Presentation Tips
Once your cake is frosted, it’s time to think about presentation. Here are a few tips to make your chocolate peanut butter cake look as good as it tastes:
- Smooth Finish: Use a spatula to smooth out the frosting, giving the cake a clean and elegant look.
- Garnish with Chocolate Shavings: Sprinkle chocolate shavings or mini chocolate chips on top for added texture and visual appeal.
- Peanut Butter Drizzle: Melt a small amount of peanut butter and drizzle it over the top for a beautiful finishing touch.
- Add Fresh Fruits: Sliced strawberries or raspberries on top can add a burst of color and freshness.
How to Serve Chocolate Peanut Butter Cake
To serve, use a sharp knife to cut clean, even slices. This cake pairs well with a scoop of vanilla ice cream or a dollop of whipped cream on the side. Serve with a hot cup of coffee or cold glass of milk to enhance the rich, creamy flavors.
Presentation Ideas for Chocolate Peanut Butter Cake
If you’re serving this cake for a special occasion, try these presentation ideas:
- Layered Chocolate Drizzle: Drizzle both melted chocolate and peanut butter on top for a layered effect.
- Add Crushed Peanuts: Sprinkle crushed peanuts along the edges or center for extra crunch and decoration.
- Decorative Piping: Use a piping bag to add decorative swirls or borders with the peanut butter frosting.
- Edible Gold Dust: Lightly brush the cake with edible gold dust for a glamorous touch.
Chocolate Peanut Butter Cake Recipe Tips
- Sift the Cocoa Powder: Sifting helps remove any lumps and gives the cake a smoother texture.
- Room Temperature Ingredients: Always use room temperature ingredients for the best mixing results.
- Chill the Frosting: If your frosting is too soft, chill it in the fridge for a few minutes before applying to the cake.
- Level Your Cakes: For a professional look, level the tops of your cake layers before stacking to ensure they sit evenly.
- Store Properly: Keep leftovers in an airtight container in the fridge for up to 5 days.
Frequently Asked Questions (FAQs)
Q: Can I make this cake ahead of time?
A: Yes! You can bake the cake layers a day in advance and store them in an airtight container at room temperature. Frost the cake on the day you plan to serve it for the freshest results.
Q: Can I freeze chocolate peanut butter cake?
A: Yes, you can freeze the unfrosted cake layers. Wrap them tightly in plastic wrap and foil, then store in the freezer for up to 3 months. Thaw at room temperature before frosting and serving.
Q: What kind of peanut butter is best for the frosting?
A: Use creamy, no-stir peanut butter for the best results. Natural peanut butter that requires stirring may lead to a less stable frosting.
Q: Can I use a different pan size?
A: Yes, you can use an 8-inch or 10-inch pan, but you’ll need to adjust the baking time accordingly. Monitor closely to prevent over- or under-baking.
Q: How can I make the frosting less sweet?
A: If you prefer a less sweet frosting, reduce the powdered sugar by ½ cup and add an extra tablespoon of heavy cream to maintain the consistency.
