Ingredients List for Chocolate Peanut Butter Cake
This recipe is broken down into three main components: the chocolate cake, the peanut butter frosting, and optional chocolate ganache. Let’s start by gathering all the ingredients.
For the Chocolate Cake:
- 2 cups all-purpose flour
- 1 ¾ cups granulated sugar
- ¾ cup unsweetened cocoa powder
- 1 ½ teaspoons baking powder
- 1 ½ teaspoons baking soda
- 1 teaspoon salt

Substitutions and Variations
Feel free to customize this recipe based on your preferences or dietary needs. Here are some ideas for substitutions and variations:
- Gluten-Free: Substitute the all-purpose flour with a 1:1 gluten-free flour blend for a gluten-free version.
- Dairy-Free: Replace the milk in the cake and frosting with almond milk or coconut milk, and use dairy-free butter and cream.
- Sugar-Free: Substitute granulated sugar with a sugar alternative like monk fruit sweetener, and use sugar-free powdered sugar in the frosting.

Step-by-Step Cooking Instructions

Now that you have all your ingredients ready, let’s start baking! Follow these step-by-step instructions to create your Chocolate Peanut Butter Cake.
1. Preheat the Oven and Prepare the Pans
Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans (or line the bottoms with parchment paper) to prevent sticking.
2. Make the Chocolate Cake Batter
In a large mixing bowl, sift together the flour, sugar, cocoa powder, baking powder, baking soda, and salt. Stir until everything is well combined.
In a separate bowl, whisk together the eggs, milk, vegetable oil, and vanilla extract. Slowly add the wet ingredients to the dry ingredients, mixing until just combined. Gradually add the boiling water (or hot coffee) to the batter, stirring constantly until smooth. The batter will be thin, but that’s okay!
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. Once baked, let the cakes cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely.
4. Prepare the Peanut Butter Frosting
While the cakes are cooling, make the peanut butter frosting. In a large bowl, beat together the softened butter and peanut butter until smooth and creamy. Gradually add the powdered sugar, one cup at a time, mixing on low speed. Add the vanilla extract and heavy cream (or milk), and beat until the frosting is smooth and fluffy. If the frosting is too thick, add more cream, one tablespoon at a time, until you reach your desired consistency.
5. Frost the Cake
Once the cakes are completely cool, it’s time to assemble. Place one cake layer on a serving plate or cake stand. Spread a thick layer of peanut butter frosting on top. Place the second cake layer on top and frost the entire cake with the remaining peanut butter frosting. Smooth the sides and top with an offset spatula for a clean finish.
6. Make the Optional Chocolate Ganache (if desired)
If you want to take your cake to the next level, you can add a chocolate ganache topping. In a small saucepan, heat the heavy cream until it just starts to simmer (don’t let it boil). Remove from heat and pour it over the chocolate chips in a heatproof bowl. Let it sit for 2 minutes to melt, then stir until smooth. Stir in the butter for a glossy finish.
7. Decorate the Cake
Once the ganache is slightly cooled, drizzle it over the top of the cake, letting it drip down the sides for a dramatic effect. You can also pipe extra peanut butter frosting around the edges or garnish with chopped peanuts, chocolate chips, or peanut butter cups.
How to Cook Chocolate Peanut Butter Cake: A Step-by-Step Guide
Let’s summarize the essential steps to bake your delicious Chocolate Peanut Butter Cake:
- Preheat the Oven and Prepare Pans: Grease and flour two 9-inch round pans and preheat the oven to 350°F.
- Make the Chocolate Cake Batter: Mix dry ingredients, then whisk wet ingredients together and combine. Add boiling water or coffee and mix until smooth.
- Bake: Divide the batter between two pans and bake for 30-35 minutes.
- Prepare the Frosting: Beat peanut butter, butter, powdered sugar, vanilla, and cream until fluffy.
- Frost the Cake: Layer and frost the cake once it's fully cooled.
- Make Ganache (Optional): Heat cream and pour it over chocolate chips, then drizzle over the cake.
Common Mistakes to Avoid
Baking cakes can be tricky, so here are a few common mistakes to avoid when making this Chocolate Peanut Butter Cake:
- Not Cooling the Cakes Completely: If you frost the cakes while they’re still warm, the frosting will melt. Make sure the cake layers are fully cooled before frosting.
- Overmixing the Batter: Overmixing can lead to a tough, dense cake. Mix until just combined for a light, fluffy texture.
- Skipping the Parchment Paper: Using parchment paper in the cake pans ensures the cakes release easily. It’s worth the extra step to avoid sticking.
Serving and Presentation Tips
For a showstopping presentation, here are some creative ways to serve your Chocolate Peanut Butter Cake:
- Drip Effect: Pour the chocolate ganache over the top, allowing it to drip down the sides for a dramatic look.
- Peanut Butter Cups: Decorate the top with mini peanut butter cups for an extra indulgent touch.
- Swirls: Use a spatula to create swirls or patterns in the frosting on top of the cake.
- Extra Garnish: Sprinkle chopped peanuts, chocolate chips, or even a dusting of cocoa powder over the top.
How to Serve Chocolate Peanut Butter Cake
Serve your Chocolate Peanut Butter Cake at room temperature for the best flavor and texture. Each slice is perfectly complemented with a scoop of vanilla ice cream or a glass of cold milk. This cake is rich, so smaller slices go a long way. If you’re serving it at a party, you can pre-slice the cake and add decorative elements like whipped cream or extra peanut butter drizzle on each plate.
Presentation Ideas for Chocolate Peanut Butter Cake
For an eye-catching presentation, here are some fun ideas:
- Layered Cake: Use a piping bag to pipe peanut butter frosting between the layers for a more professional look.
- Naked Cake: For a modern twist, leave the sides of the cake partially unfrosted for a rustic, naked cake style.
- Peanut Butter Drizzle: Drizzle melted peanut butter on top of the chocolate ganache for an extra decorative touch.
Chocolate Peanut Butter Cake Recipe Tips
Here are some pro tips to ensure your cake turns out perfectly every time:
- Room Temperature Ingredients: Ensure your butter, eggs, and milk are at room temperature for smoother mixing and a better texture.
- Don’t Overbake: Keep a close eye on the cakes while baking. Remove them as soon as a toothpick inserted into the center comes out clean to prevent dryness.
- Make Ahead: This cake actually tastes better the next day, as the flavors have time to meld together. You can make the cake layers ahead and store them in the fridge or freezer until ready to frost.
Frequently Asked Questions (FAQs)
Q: Can I freeze Chocolate Peanut Butter Cake?
A: Yes! Wrap the unfrosted cake layers tightly in plastic wrap and freeze for up to 3 months. Thaw overnight in the fridge before frosting and serving.
Q: How long will the cake last?
A: The cake can be stored in an airtight container in the fridge for up to 5 days. Bring it to room temperature before serving.
Q: Can I make this cake in advance?
