Step-by-Step Guide to Making Chocolate Cake with Peanut Butter Frosting
Follow these foolproof steps to bake a rich, moist chocolate cake topped with creamy peanut butter frosting.
Step 1: Gather Your Ingredients
For the Chocolate Cake:
- 2 cups all-purpose flour
- 1 ¾ cups granulated sugar
- ¾ cup unsweetened cocoa powder (Dutch-processed for a deeper flavor)
- 2 teaspoons baking soda
- 1 teaspoon baking powder
- 1 teaspoon salt
- 2 large eggs (room temperature)
- 1 cup buttermilk (or substitute with milk + 1 tbsp vinegar)
- ½ cup vegetable oil (or melted butter)
- 2 teaspoons vanilla extract
- 1 cup hot coffee (enhances chocolate flavor)
For the Peanut Butter Frosting:
- 1 cup unsalted butter (softened)
- 1 cup creamy peanut butter (processed brand like Jif or Skippy)
- 3 cups powdered sugar
- ¼ cup heavy cream or milk (adjust for consistency)
- 1 teaspoon vanilla extract
- ¼ teaspoon salt
Step 2: Prepare the Cake Batter
- Preheat your oven to 350°F (175°C). Grease and line two 9-inch round cake pans with parchment paper.
- In a large bowl, whisk together the flour, sugar, cocoa powder, baking soda, baking powder, and salt.
- Add the eggs, buttermilk, vegetable oil, and vanilla extract. Mix until just combined.
- Slowly pour in the hot coffee, whisking until the batter is smooth. It will be thin, but that’s normal!
Step 3: Bake the Cake
- Divide the batter evenly between the prepared pans.
- Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.
- Let the cakes cool in the pans for 10 minutes, then transfer them to a wire rack to cool completely.
Step 4: Make the Peanut Butter Frosting
- In a large bowl, beat the butter and peanut butter with an electric mixer until smooth and creamy.
- Gradually add the powdered sugar, mixing on low speed.
- Pour in the heavy cream, vanilla extract, and salt, then beat on medium-high speed for 2–3 minutes until fluffy.
- If the frosting is too thick, add a tablespoon of milk at a time until it reaches the perfect spreading consistency.
Step 5: Assemble and Frost the Cake
- Place one cake layer on a serving plate. Spread an even layer of peanut butter frosting on top.
- Add the second cake layer, then frost the top and sides with the remaining frosting.
- For an extra touch, drizzle melted chocolate over the cake and sprinkle crushed peanuts on top.
Step 6: Serve and Enjoy!
- Slice the cake with a hot knife for clean, professional-looking cuts.
- Serve with a cold glass of milk or a scoop of vanilla ice cream for the ultimate indulgence.
- Store leftovers in an airtight container at room temperature for up to 3 days or refrigerate for a week.

2. Why did my peanut butter frosting separate?

Pro Tips & Tricks for the Best Chocolate Cake with Peanut Butter Frosting
Want to take your chocolate cake with peanut butter frosting to the next level? Follow these expert baking tricks to ensure the perfect texture, flavor, and presentation every time!
1. Use Hot Coffee for a Richer Chocolate Flavor
Adding hot brewed coffee to your batter intensifies the chocolate taste without making it taste like coffee. The heat also helps bloom the cocoa powder, unlocking deeper flavors.
2. Don’t Overmix the Batter
For a soft, tender crumb, mix the batter just until the ingredients are combined. Overmixing activates the gluten too much, making the cake dense and tough.
3. Room Temperature Ingredients are Key
Make sure your eggs, butter, and milk are at room temperature before baking. This ensures even mixing and a smoother batter, leading to a better rise in the oven.
4. Use Buttermilk for Extra Moisture
Buttermilk adds a slight tang while keeping the cake soft and moist. No buttermilk? No problem! Mix 1 cup of milk with 1 tablespoon of vinegar and let it sit for 5 minutes as a perfect substitute.
5. Freeze Cake Layers for Easier Frosting
For ultra-smooth frosting, let your cake layers cool completely, then wrap them in plastic wrap and freeze for 30–60 minutes before assembling. This keeps crumbs from mixing into the frosting.
6. Add a Pinch of Salt to the Peanut Butter Frosting
A small amount of salt balances the sweetness and enhances the peanut butter’s natural flavor, making the frosting even more irresistible.
7. Use a Hot Knife for Clean Slices
Want picture-perfect cake slices? Dip your knife in hot water, wipe it dry, and cut through the cake for neat, bakery-style slices every time.
8. Store for Maximum Freshness
- Keep the cake at room temperature in an airtight container for up to 3 days.
- Refrigerate for up to a week, but bring it back to room temp before serving for the best texture.
- Want to save some for later? Wrap slices in plastic wrap and freeze for up to 3 months!
With these expert tricks, you’ll bake a flawless chocolate cake with peanut butter frosting every single time. Happy baking!
