Chocolate Reese’s Peanut Butter Cake is a moist chocolate cake with peanut butter frosting and buttercream frosting! Perfect for the Reese’s lover in your life!

We had the idea of this amazing chocolate peanut butter Reese’s Cake a month ago for a friend’s birthday cake. Peanut butter, chocolate, cake, (I couldn’t pass up any of those!). I’m a cake person, and NOT an icing fan. People tell me I’m crazy because of that.

But I have found a couple of icings I really like. This chocolate peanut butter Reese’s cake has all of my favorite stuff in it resulting in my dream cake.

❤️ Why you’ll love this cake:

  • 100% homemade
  • Fudgy chocolate cake
  • Melt in your mouth chocolate and peanut butter frosting
  • Like a Reese’s cup, but so much better!

How to Make Chocolate Cake

  • You’re going to first put flour, sugar, cocoa, baking powder, baking soda and salt together in a bowl.
  • In a stand mixer, mix the buttermilk, oil, eggs and vanilla.  Then pour the dry ingredients in the mixer slowly with the wet ingredients. Add in the coffee last and mix well. Trust me on the coffee…it enhances the chocolate flavor. 😋
  • Pour the batter into two greased and floured pans. The batter will be thin, but that’s fine!
  • Bake for about 25 minutes or until a toothpick inserted in the center comes out clean.
  • Allow the cakes to cool in the pans for 10 minutes. Loosen the edges of the cake with a knife, then turn the cakes out on parchment paper or a wire rack to cool completely before you frost them.

Make the Frostings

While the cakes are cooling whip up the peanut butter frosting and the chocolate frosting. The key with both is to beat the butter first until it is almost white in appearance. Then add the rest of the ingredients. W

e like to use a stand mixer to beat homemade frostings because they end of the lightest and fluffiest that way. If you don’t have a stand mixer, you can use a high powered hand mixer.

Assembling the Cake

  • Place one cake layer on a cake plate.
  • Spread on the Peanut Butter Frosting on one half.
  • Then put the other cake on top.
  • Spread that delicious Chocolate Buttercream Frosting all over the top and sides of the cake. If your cake is not even, just make the icing a little thicker in the places it needs to be to make an even-looking cake.

At this point, you could stop. After all, the cake will look and taste delicious as it is!

I like to decorate cakes, so I took this cake one step further. It’s really not as hard as it looks. You can totally do this.

Decorating a Cake with Wilton Tips

  • Take a Wilton 2D tip and put it in an icing bag. Fill the bag with icing and squeeze the frosting down to get out the air bubbles.
  • You can decorate it any way you want and with any tip you want, but to get the look that I have on this cake, just squeeze until your star is the size you want it and pull away to make a flower. I put flowers all around the top and bottom of the Reese’s cake.

Then cut up Reese’s into small pieces and sprinkle them over the top as desired.

    • Add in the salt and vanilla. Mix until incorporated.
    • With the mixer on low speed, slowly add in the powdered sugar and cocoa powder.

    I have been making this cake for about two years, and it is now my boys’ favorite. They request it for every special occasion: birthdays, graduations, etc. They refuse to accept any other cake for their special “days”. It is so delicious. Thank you for sharing!

    Why did you peel baking paper off the cakes? Did you put it on, so tops wouldn’t burn?

    Easy-to-follow instructions, common ingredients. I made this cake for a 16-year-old’s birthday. It was a big hit. I poured a little of the batter into a cupcake and used only the chocolate frosting to make an individual cake for one grandchild who loves chocolate and hates peanut butter. PLENTY of frosting.

    This cake was easy and delicious. Moist and decadent. I was concerned about so little batter but it ended up perfect. Frostings were also amazing. I’ve needed a good peanut butter frosting recipe!

    This recipe was great! My icing turned out a little interesting, but I think it was because I’m living in Belize and my kitchen was at least 90+ degrees at the time.:) Thanks for sharing!
