Do you like Chocolate? How about Peanut Butter? How about together in a CAKE?
I can’t take full credit for this cake, I adapted it from the King Arthur blog.In all its glory, the original recipe is made from scratch and is 4 layers high!

But I like easy, and adapted the recipe a little.

Just because it’s easy, doesn’t mean this cake won’t knock your socks off!

Grab your aprons, and let’s get started

Buckeye Peanut Butter Fudge Cake recipe at TidyMom.net

Buckeye Peanut Butter-Fudge Cake



  • 1 Duncan Hines Moist Deluxe Dark Chocolate Fudge Cake Mix (+ ingredients listed on box)

Peanut Butter Filling:

  • 4 cups (1-lb. box) powdered sugar
  • 1 ½ cups peanut butter
  • 2 teaspoons vanilla extract
  • 3/4 cup milk

Chocolate Ganache (icing)

  • 12 ounces semi-sweet chocolate chips
  • 3/4 cup heavy whipping cream
  • 6 tablespoons butter



  1. Mix and bake the cake according to the box in 2 round cake pans. Let cool.

Peanut Butter Filling

  1. With and electric mixer, beat the powdered sugar, peanut butter, and vanilla until well combined. Gradually add milk. It will taste as good as it sounds!

Chocolate Ganache (icing)

  1. Place chocolate chips in a medium bowl and set aside.
  2. In a small saucepan, heat cream and butter until just before the boiling stage. Pour over the chocolate chips.
  3. Stir until smooth.

Put it all together

  1. I only made 2 layers, mainly because a 4 layer cake will not fit under my cake saver. But if you’d like, you can slice your 2 layers into 4 layers.
  2. Top your layer(s) with peanut butter filling.
  3. Pour warm ganache over the top of the cake, spread with an angled spatula, and encourage it to dribble over the sides!


Don’t use just any chocolate cake mix, use Duncan Hines Moist Deluxe Dark Chocolate Fudge Cake Mix. This is THE BEST! I promise!
