Chocolate Peanut Butter Cake
What's your Take?

There is something special about the combination of creamy peanut butter and silky chocolate — a true match made in candy heaven. This cake recipe is perfect for a busy mama because it combines a store bought cake mix with creamy, homemade, TO-DIE-FOR, peanut butter-cream icing. The final result is so decadent looking (and tasting!), no one will know it wasn't all made from scratch. This is the perfect treat to serve at a kids' party that adults will like, too. And your friends will be begging you for this icing recipe; it's THAT GOOD!

What you'll need

  • 1 package Devil's-Food cake mix
  • 1 1/3 cups water
  • 1/2 cup vegetable oil
  • 3 large eggs
  • 2 tablespoons instant espresso or instant coffee powder
  • 2 sticks unsalted butter, softened
  • 2 cups confectioner's sugar
  • 28 ounces smooth peanut butter
  • 4 - 5 Reese's® peanut butter cups, each cut in half
Helpful Tip:

If frosting gets too soft, pop it back in the fridge for a few minutes to tighten up. Love Reese's® and want more? Why not add some Reese's® pieces to the outside of your cake too?
Freeze Reese's® peanut butter cups before cutting. Frozen chocolate makes a cleaner, more even cut and neater cake.
Use cocoa powder instead of white flour to dust cake pans before filling with batter.

How to make it

  1. Preheat oven to 350 degrees.

  2. Grease and flour two 8-inch round cake pans.

  3. In a large bowl using a hand mixer, or in the bowl of a stand mixer, beat cake mix, instant coffee, water, oil, and eggs until mixture is well combined, about 1 minute.

  4. Pour mixture into the cake pans, distributing it evenly so each pan has half.

  5. Bake for 32 - 37 minutes or until a toothpick inserted into the center of the cakes comes out clean.

  6. Cool cakes in pans for about 30 minutes, then turn them out onto a cooling rack and continue to cool for an additional 30 minutes before icing.

  7. To make the frosting, place butter into a stand mixer and beat on low speed. Slowly add in the confectioner's sugar and beat until light and creamy, about 1 - 2 minutes. Increase the mixer speed to medium and slowly add in peanut butter. Beat until well incorporated, about 2 - 3 minutes.

  8. Allow frosting to sit in the fridge for 15 minutes before using.

  9. To frost your cake, place 1 layer of the cake, flat side up, on a flat plate or cake stand. Using an offset spatula, spread the top with frosting. Place the second layer on top, rounded side up, and spread the frosting evenly on the top and sides of the cake.

  10. Decorate the top of cake with Reese's® peanut butter cup halves.
