Reese’s Peanut Butter Cake

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!

I have been excited about getting this whole blog thing started, but I’ll just say, it’s a lot of work! Hopefully I will get the hang of editing pictures, typing recipes, publishing recipes, taking pictures of food, making it look good, and of course, eating it! After all, how can you describe something if you’ve never tasted it?

We had the idea of this amazing Reese’s Peanut Butter 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 cake has all of my favorite stuff in it resulting in my dream cake.

We made it for my grandma’s birthday, and boy, did she love it! The cake is based off of a recipe from Sally’s Baking Addiction. It’s definitely a keeper!

Reese's Peanut Butter 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.

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. Loosen the edges of the cake with a knife, then turn the cakes out on parchment paper to cool.

While the cakes are cooling, mix up the Peanut Butter Frosting and the Chocolate Buttercream Frosting (ingredients shown below).  Be sure to mix both frostings well so they turn out fluffy!

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 cake. Make it thick in some places in order to make it look even. To make spreading the frosting even easier, I like to put my cake in the freezer to harden a little. That way you can spread the frosting better.

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. You can do it, too if you want. It’s really not as hard as it looks.

Take a 2D tip and put it in an icing bag. Fill the bag with icing and get out the air bubbles.


You can decorate it anyway you want and with any tip you want, but to get what I’m doing, 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 cake.

The Reese’s Cups are pretty much the last step. Cut them up and sprinkle them over the top as desired.

If there is a little Reese’s piece that looks lonely, eat it.

    I made this last week for my best friends bday and omg, this recipe is amazing. Thank you for making such a spectacular cake. It inspired me to dig our fancy icing bag out of a closet and give it a whirl. It looked beautiful and just thinking about it makes me hungry all over again. I ended up cutting the Reese’s in half and lining them around the edge of the cake and using Reese’s Pieces to give it a little color (a pic is up on my blog if you scroll down to the very bottom of this post ). Thanks again for the awesome recipe. :)

      So glad you liked it!! I crave this cake, too…it is dangerous to have around our house:) Thanks for stopping by!

    Lizzy, this is one fabulously over-the-top, big, beautiful cake; it’s outrageously creative and looks irresistible.

    Just like you, I am also a cake person: layer cakes, cupcakes, birthday cakes, wedding cakes, cheesecakes, potato cakes…but I digress. I love mixing them, baking them, icing them, and most of all…eating them…mostly late at night before bedtime, as I get very sleepy after eating anything sugary sweet for the last several years; IDK why!

    BTW, I don’t think God created a dog anywhere, who can resist peanut butter. Just the way it is. Besides, watching your pooch working so hard to EAT the pnut butter is one of the greatest forms of entertainment ever!

    Well done! I look forward to seeing more from your kitchen soon.

      Thank you, Mary, for your kind words! You made our morning. This is absolutely our favorite family cake. And yes, watching dogs eat peanut butter always makes me smile. :) Glad you found us!
