Peanut Butter Brownie Bites


Brownie Cookies:

  • 1 Box Devil's Food Cake mix I like pillsbury
  • 2 eggs
  • 1/3 C. oil
  • 1 Tbsp. brown sugar

Peanut Butter Frosting:

  • 1/2 C. butter
  • 1/2 C. peanut butter smooth
  • 2 tsp. vanilla extract
  • 2-4 Tbsp. milk
  • 2-3 C. powdered sugar

Peanut Butter Chocolate Ganache:

  • 3/4 C. chocolate chips
  • 1/2 C. peanut butter smooth

Peanut butter cups, chopped (I used the mini ones from Trader Joe's)


  1. 1. Preheat oven to 350 degrees and line pans with parchment paper.
  2. 2. Sift cake mix into a large bowl to remove lumps.
  3. 3. Add eggs, oil and brown sugar and stir until smooth. Batter will be thick.
  4. 4. Scoop walnut sized dough balls onto cookie sheets and gently press them down to make them a little flatter. (Cake mix cookies can sometimes bake up tall and not spread out like normal cookies.)
  5. 5. Bake for 6-8 minutes depending on how fudgey you want them to be.
  6. 6. Let cool.
  7. 7. Peanut Butter Frosting: Beat butter and peanut butter together. Add vanilla extract and 2 Tablespoons milk. Slowly add in powdered sugar until you reach your desired consistency. Add more milk if it becomes too thick.
  8. 8. Peanut Butter Chocolate Ganache: Place chocolate chips and peanut butter in a microwave proof bowl and heat in the microwave (about 1 minute). Stir until smooth.
  9. 9. To assemble: Frost cookies. I used a large circle tip in a piping bag to pipe out a little circle and then I used a spoon to flatten the frosting out and create a sort of "well" to hold the ganache. Put a spoonful of ganache on each frosting cookie and then top with chopped peanut butter cups!
