And what better way to celebrate this delectable pairing than with a rich and moist chocolate cake topped with luscious peanut butter frosting? In this blog post, we’ll dive into the world of chocolate cake with peanut butter frosting and share a mouthwatering recipe that will have you running to the kitchen in no time.

The Perfect Match: Chocolate and Peanut Butter

Before we get into the details of this delectable dessert, let’s take a moment to appreciate the culinary chemistry between chocolate and peanut butter. Chocolate, with its deep, bittersweet flavor, provides a perfect contrast to the creamy and slightly salty notes of peanut butter. When these two ingredients come together, they create a harmonious symphony of taste and texture that’s nothing short of heavenly.

The Chocolate Cake: A Rich Foundation

A great chocolate cake is the cornerstone of this delightful dessert. When making a chocolate cake for this recipe, you’ll want to use high-quality cocoa powder to achieve that rich, intense chocolate flavor. Here’s a basic recipe to get you started:

Ingredients for Chocolate Cake:

  • 2 cups all-purpose flour
  • 1¾ cups granulated sugar
  • ¾ cup unsweetened cocoa powder
  • 1½ tsp baking powder
  • 1½ tsp baking soda
  • 1 tsp salt
  • 2 large eggs
  • 1 cup buttermilk
  • ½ cup vegetable oil
  • 2 tsp pure vanilla extract
  • 1 cup hot water


  • Preheat your oven to 350°F (175°C) and grease and flour two 9-inch round cake pans.
  • In a large mixing bowl, sift together the flour, sugar, cocoa powder, baking powder, baking soda, and salt.
  • Add the eggs, buttermilk, vegetable oil, and vanilla extract. Mix until the batter is smooth and well combined.
  • Stir in the hot water, which will thin the batter. Don’t worry; it’s supposed to be thin.
  • Pour the batter evenly into the prepared pans.
  • Bake in the preheated oven 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 before transferring them to a wire rack to cool completely.

The Star of the Show: Peanut Butter Frosting

Now that you have your decadent chocolate cake, it’s time to prepare the star of the show – the peanut butter frosting. This creamy and indulgent frosting is incredibly easy to make and will complement the chocolate cake perfectly.

Ingredients for Peanut Butter Frosting:

  • 1 cup unsalted butter, softened
  • 1 cup creamy peanut butter
  • 4 cups powdered sugar
  • 1/4 cup whole milk
  • 1 tsp pure vanilla extract
  • A pinch of salt


  • In a large mixing bowl, beat the softened butter and peanut butter together until smooth and creamy.
  • Gradually add the powdered sugar, one cup at a time, mixing well after each addition.
  • Pour in the milk, vanilla extract, and a pinch of salt, and beat until the frosting is light and fluffy.

Assembly: Bringing It All Together

Now that you have your chocolate cake and peanut butter frosting ready, it’s time to assemble this delightful dessert:

  • Place one of the chocolate cake layers on a serving plate or cake stand.
  • Spread a generous layer of peanut butter frosting over the top.
  • Carefully place the second cake layer on top.
  • Frost the top and sides of the entire cake with the remaining peanut butter frosting.
  • For an extra touch of decadence, consider garnishing the cake with chopped peanuts, chocolate shavings, or even a drizzle of melted chocolate.

Variations and Tips

While the classic chocolate cake with peanut butter frosting is already a crowd-pleaser, there are several ways to customize and elevate this dessert to suit your preferences:

1. Add Some Texture:

  • Consider mixing in chopped peanuts, chocolate chips, or even mini Reese’s peanut butter cups into the cake batter for a delightful crunch in every bite.

2. Go Dark and Rich:

  • Experiment with dark chocolate for a more intense cocoa flavor in your cake. Dark chocolate pairs exceptionally well with peanut butter.

3. Swirl It Up:

  • Create a marbled effect by adding dollops of peanut butter frosting between the cake layers and gently swirling it with a toothpick before applying the final layer of frosting.

4. Salted Caramel Drizzle:

  • For an extra layer of decadence, drizzle some homemade salted caramel sauce over the top of the cake. The sweet and salty contrast will take your dessert to the next level.

5. Mini Cupcakes or Cake Pops:

  • If you want to make this dessert more portable or serve it at a party, consider making mini cupcakes or cake pops instead of a traditional layer cake. The small, bite-sized treats are perfect for sharing.

6. Dietary Modifications:

  • If you have dietary restrictions, you can adapt this recipe by using gluten-free flour, dairy-free alternatives for milk and butter, or natural peanut butter for a lower sugar option.

Storing Your Creation

Once you’ve devoured your chocolate cake with peanut butter frosting (which won’t take long, we promise), you’ll want to store any leftovers properly. Cover the cake or cupcakes with plastic wrap or store them in an airtight container and keep them in the refrigerator. This dessert can be enjoyed for several days, though it’s so delicious; it might not last that long!
