Chocolate Peanut Butter Reese’s Cake

Calling all chocolate peanut butter lovers! This Chocolate Peanut Butter Reese’s Cake is a gorgeous site…and easy to make! Decorate the top simply with Wilton 1M tip and Reese’s cups. My favorite part? The homemade peanut butter frosting and chocolate buttercream. It’s the perfect frosting combination!

Let’s talk about how to make this easy cake!

Homemade Chocolate Cake

If you’re looking for an amazing homemade chocolate cake that you can use as the base for so many different recipes, this cake recipe is it. It’s easy to make and I’ve never had it fail. It is sometimes hard to get homemade cakes that have the same texture as a cake mix…light, fluffy and moist. But this one has it. If you’re new to making homemade cakes, this is a chocolate cake recipe you should try!

Here are a few hints:

  • I love that this cake recipe uses all-purpose flour. No need for cake flour here!
  • Be sure to use unsweetened cocoa powder. We’ve used several different kinds with success. Dark chocolate, raw cacao powder and traditional unsweetened cocoa powder.
  • Use buttermilk. This is what helps the cake fluff up so nicely. We recommend buying buttermilk from the store, bu tif you don’t have buttermilk, simply add ½ tablespoon of white vinegar to the ½ cup measuring cup, then fill the rest of the measuring cup with milk. After a few minutes, the milk will start to curdle slightly. This will work a substitute for buttermilk.
  • The batter will be thin.

Peanut Butter Frosting

This frosting is so easy to make and is delicious. It tastes like the center of a Reese’s cup. Mmm… Beat all of the ingredients together until the frosting is smooth. Natural peanut butter does not work well. We use regular creamy peanut butter. Add the heavy cream 1 tablespoon at a time until the frosting is the consistency you’d like.

Chocolate Buttercream

This chocolate buttercream gets rave reviews every time we serve it on cakes, cupcakes, brownies or cookies. This frosting comes together even more easily than the peanut butter frosting. And just as above, add the heavy cream one tablespoon at a time so the frosting doesn’t get too runny.

This is a great chocolate frosting for piping and holds its shape well!

How to Store Reese’s Cake

This cake is safe stored at room temperature for 24 hours. We recommend refrigerating the cake if you have any left after that.

How to Freeze Cake

If you have leftovers and need to freeze the cake, wrap the cake well with plastic wrap or in an airtight container. To defrost, allow the cake to cool to room temperature completely before unwrapping it.

Chocolate Cake:

  • Preheat oven to 350 degrees. Grease and flour 2 round 9-inch cake pans.
  • For the cake, put flour, sugar, cocoa, baking powder, baking soda and salt in a bowl and mix well.
  • In a stand mixer, mix the buttermilk, oil, eggs, vanilla together. Slowly add in the mix of dry ingredients while the mixer is on low. Add the coffee and make sure everything is combined. The batter will be very thin.
  • Pour the batter into the prepared pans and bake for about 25 minutes or until a toothpick inserted in the middle comes out clean.
  • Turn the cakes out onto a cooling rack. While the cakes are cooling, make your frostings.

Peanut Butter Frosting:

  • In a bowl, blend together peanut butter, powdered sugar, butter, and milk 3-4 minutes or until light and fluffy.

Chocolate Buttercream:

  • In a stand mixer with the beater blade, beat the butter for 1-2 minutes until it is smooth, creamy and nearly white in appearance.
  • Add in the salt and vanilla. Mix until incorporated.
  • With the mixer on low speed, slowly add in the powdered sugar and cocoa powder.
  • Add the heavy cream, a tablespoon at a time, mixing slowly until it is the consistency that you'd like.
  • Beat for 1 minute on medium speed until smooth and creamy.

Assemble The Cake:

  • Frost the top of the first cake with the Peanut Butter Frosting. Then layer the other half of the cake on top. Frost the outside of the cake with the Chocolate Buttercream Frosting.
  • Pipe flowers on top with the leftover Peanut Butter Frosting and/or decorate as desired with chopped Reese's Peanut Butter Cups.
