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.

    This cake is fabulous! You will not be disappointed! It was the show stopper Groom’s cake at my daughter’s wedding and my son in law’s hands down favorite cake.

    I made this cake for my husband’s birthday yesterday. WOW! The cake itself was so moist and dense and the peanut butter frosting was perfection. I have added this to my recipe box and will certainly be making it again. The only thing I did differently was sub out the buttermilk with 1 Tbsp white vinegar in 1 cup of milk in order to avoid a trip to the store. 10/10!!!

    Made this for my sister who can’t live without peanut butter and chocolate! She absolutely loved this and I ended up stealing a bit for myself :). The buttercream is so smooth and the cake was so rich, it’s the perfect cake! I added a few Reese’s pieces in between and on top of the cake and that was just the cherry on top!

    So glad to have found this since I am already familiar with Sally’s Chocolate Cake recipe!

    If I use just the peanut butter frosting all over the cake (no chocolate frosting at all), will the cake still taste good? I want to have a good balance of the chocolate and PB.

    Also, will the amount stated in the recipe be enough?

    I have to make this cake in two days and have no time to experiment 😉

    GLUTEN FREE- I just made this cake for
    My 14yo”s birthday. We are 100% gluten free and I made this recipe exactly as it is written except I used Bob’s red mill 1to1 gluten free flour. It was so good. I made the cakes 24 hours ahead of time and iced them today. The cake was so incredibly moist and rich and perfect!! I had to make my own powdered sugar because we also have a corn allergy, but that is easy to do as well.

    I saw this recipe and decided to do something different for my daughter’s birthday cake request as she wanted a peanut butter cake. So glad I tried this. It did not disappoint. It was amazing and everyone loved it. Thank you for sharing the recipe! The salt in the icing was perfect!! What a great recipe. Thanks again, I wouldn’t change a thing about this recipe

    Amazing Recipe! I don’t love canola oil so next time i would replace that with melted butter. But the original recipe was unbelievable. The most moist cake I have ever made (maybe bc of the oil haha). I had so much peanut butter frosting left over that I when back made every other flower into a bigger flower. If you do put chopped up peanut butter cups in the middle I recommend chopping them finely because it made my cake a little hard to cut into. I also used dark chocolate peanut butter cups from trader joes and it was… Read more »

    I’ve made this cake a couple of times now, super decadent and delicious. Including ingredient weights really helps, I got them from another recipe with identical ingredients but with weights. Notably, 220g AP flour and 65g cocoa powder for the cake. And I made a bit more of the chocolate buttercream frosting. Definitely the prettiest cake I’ve made!
