What Is a Chocolate Peanut Butter Cake?
A Chocolate Peanut Butter Cake is a rich, layered dessert that blends two universally beloved flavors: chocolate and peanut butter. The cake typically consists of moist, decadent chocolate cake layers that are stacked and filled with a creamy peanut butter frosting. Some variations also feature a chocolate ganache or peanut butter drizzle for added richness. This cake is perfect for lovers of the sweet and salty combo and satisfies every chocolate and peanut butter craving in the most delightful way possible.
Ingredients List for Chocolate Cake Layers
To create the perfect base for your Homemade Chocolate Peanut Butter Cake, you’ll need the following ingredients for the chocolate cake layers:
- 2 cups all-purpose flour
- 2 cups granulated sugar
- ¾ cup unsweetened cocoa powder
- 2 teaspoons baking powder
- 1½ teaspoons baking soda
- 1 teaspoon salt
- 1 cup whole milk
- ½ cup vegetable oil
- 2 large eggs
- 2 teaspoons vanilla extract
- 1 cup boiling water
These ingredients combine to form a rich, chocolatey batter that’s moist and tender, making it the perfect foundation for the peanut butter frosting.
Ingredients List for Peanut Butter Frosting
For the creamy peanut butter frosting, you will need the following:
- 1½ cups creamy peanut butter (natural or regular)
- 1 cup unsalted butter, softened
- 4 cups powdered sugar
- ¼ cup heavy cream (more if needed)
- 1 teaspoon vanilla extract
- Pinch of salt
This frosting is smooth, creamy, and pairs perfectly with the chocolate cake layers. You’ll be spreading this between the layers of cake and around the entire exterior for an irresistible finish.
Substitutions and Variations
One of the best parts of making your own cake is that you can customize it to fit your preferences. Here are some substitutions and variations you can try with this Chocolate Peanut Butter Cake recipe:
- Gluten-Free Option: Substitute the all-purpose flour with a gluten-free flour blend.
- Dairy-Free Option: Use almond milk or coconut milk in place of whole milk. Swap butter with vegan butter or coconut oil for the frosting.
- Add Extra Texture: Stir in some chopped peanuts or chocolate chips into the frosting or cake batter for added crunch.
- Chocolate Ganache Topping: For an extra layer of indulgence, add a rich chocolate ganache on top. Melt 1 cup of chocolate chips with ½ cup of heavy cream, and pour it over the frosted cake.
- Peanut Butter Drizzle: If you want even more peanut butter flavor, melt ½ cup peanut butter with a tablespoon of butter, and drizzle it over the cake for decoration.
Feel free to mix and match these options depending on your taste or dietary needs.
Step-by-Step Cooking Instructions

Now that you have your ingredients ready, it’s time to get cooking! Follow these detailed steps to make your Homemade Chocolate Peanut Butter Cake:
Step 1: Preheat Your Oven
Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans to ensure the cakes don’t stick when they bake.
Step 2: Mix the Dry Ingredients
In a large bowl, sift together the flour, cocoa powder, baking powder, baking soda, and salt. Set aside.
Step 3: Mix the Wet Ingredients
In another bowl, whisk together the sugar, eggs, oil, and vanilla extract until smooth. Slowly add in the milk and whisk until combined.
Step 4: Combine Wet and Dry Ingredients
Gradually add the dry ingredients into the wet ingredients, stirring until well combined. Once everything is mixed, slowly add in the boiling water. The batter will be thin, but don’t worry—this is what makes the cake moist and tender!
Step 5: Pour and Bake
Divide the batter evenly between the two prepared cake pans. Bake for 30-35 minutes, or until a toothpick inserted into the center of the cakes 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, make your peanut butter frosting. In a large bowl, beat the peanut butter and butter together until smooth. Gradually add the powdered sugar and continue beating until creamy. Add the vanilla extract and a pinch of salt. If the frosting is too thick, add heavy cream a tablespoon at a time until it reaches your desired consistency.
How to Cook Chocolate Peanut Butter Cake: A Step-by-Step Guide
This section will give you a more detailed breakdown of the entire cake-making process from start to finish. If you're newer to baking or want to ensure you get each step perfect, here’s a complete guide:
- Prepare your tools: Make sure you have your pans, mixer, spatulas, and ingredients all set up and ready to go before you start. Preheating your oven and preparing your pans first will save time.
- Mix carefully: When combining your wet and dry ingredients, make sure not to overmix. Overmixing can result in a denser cake.
- Boiling water: Adding boiling water to the chocolate batter might seem unusual, but it’s a crucial step that makes the cake extra moist and gives it a more pronounced chocolate flavor.
- Cooling time: Make sure the cake layers are completely cool before you start frosting. If they’re even a little warm, the frosting can melt, creating a mess.
- Frosting technique: Start by placing one cake layer on your serving platter, and spread a thick layer of peanut butter frosting over it. Place the second layer on top, and then frost the top and sides. A crumb coat (a thin layer of frosting) can help seal in any loose crumbs before applying a final coat.
Common Mistakes to Avoid
Baking a cake can be tricky, and there are a few common mistakes to watch out for when making this Chocolate Peanut Butter Cake:
- Overmixing the Batter: Overmixing can lead to a tough, dense cake. Stir until just combined.
- Not Letting the Cake Cool: If you try to frost a warm cake, the frosting will melt and slide off. Patience is key!
- Using Natural Peanut Butter: If using natural peanut butter, make sure it’s well-stirred and not too oily. Otherwise, it may make the frosting too runny.
Serving and Presentation Tips
Presentation is everything when it comes to serving dessert! Follow these tips to serve your Homemade Chocolate Peanut Butter Cake in style:
How to Serve Chocolate Peanut Butter Cake
- Chill the Cake: Before serving, let the frosted cake chill in the refrigerator for 30 minutes. This helps the frosting set and makes slicing easier.
- Cutting Clean Slices: Dip your knife in warm water before slicing to get clean, neat pieces of cake.
Presentation Ideas for Chocolate Peanut Butter Cake
- Decorative Piping: Use a piping bag with a star tip to pipe additional peanut butter frosting in swirls or patterns on top of the cake.
- Chocolate Shavings: Add some dark chocolate shavings or chopped peanuts around the edges or on top of the cake for extra flair.
- Drizzle: A drizzle of chocolate ganache or melted peanut butter across the top can give it that professional look.
Chocolate Peanut Butter Cake Recipe Tips
- Room Temperature Ingredients: Make sure your butter, eggs, and milk are at room temperature before you start. This ensures a smoother batter and frosting.
- Chilling Time: If the frosting becomes too soft, pop it in the fridge for 10-15 minutes to firm up before frosting the cake.
- Make Ahead: Both the cake layers and the frosting can be made ahead of time. Store the cake in an airtight container and the frosting in the refrigerator. When you’re ready to assemble, bring the frosting to room temperature.
Frequently Asked Questions (FAQs)
Can I make this cake ahead of time?

How long does this cake stay fresh?
