Ingredients & Substitutions

Cake Mix: Look for a box of chocolate fudge cake mix. Or, make your own mix by stirring together all the dry ingredients in my  Homemade Chocolate Cake Mix.

Peanut Butter Cups: You will need a total of about 40 miniature Reese’s peanut butter cups. You will chop some up for the filling and melt some more with peanut butter for the topping. If using regular-sized cups, it generally takes 2-3 minis to equal one regular-sized cup. You might also want to have a few extras chopped up for garnish.

Peanut Butter: I recommend using creamy peanut butter in the topping. However, you could use crunchy if that is what you have on hand.

Whipped Topping: To top off this rich and decadent dessert, don’t forget about the whipped topping! You can use store-bought or make your own.

Room Temperature Ingredients: Room-temperature ingredients are a good idea for the best results. Set your cream cheese out a few hours before you plan on making these amazing bars.

Yes! First, let the bars cool completely. Next, place the bars onto a parchment paper-lined baking sheet and transfer to the freezer until solid (a few hours).

Ingredients

Cake

  • 1 box (15.25 ounces) chocolate fudge cake mix
  • ½ cup (1 stick / 113 g) butter, melted
  • 1 large egg, room temperature

Filling

  • 2 ¼ cups (about 25) miniature Reese's Peanut Butter Cups, chopped

Topping

  • ¼ cup (64.5 g) creamy peanut butter,
  • 15 miniature Reese's Peanut Butter Cups
  • 1 package (8 ounces) cream cheese, softened
  • 3 large eggs, room temperature
  • ½ cup (1 stick / 113 g) butter, melted
  • 3 cups (375g) confectioners' sugar
  • whipped cream, for garnish

Instructions

  • Preheat oven to 350°F. Line a 9×13-inch baking dish with parchment paper or spray with a non-stick spray. You could also prepare the pan with homemade pan release (GOOP).*

Cake

  • In a large bowl, add the cake mix, melted butter, and egg. Mix until well combined. Press the mixture into the prepared baking pan. (The mixture will be thick)

Filling

  • Sprinkle the chopped Reese's Peanut Butter Cups over the cake mix mixture.

Topping

  • In a separate bowl, combine the peanut butter and miniature Reese's Peanut Butter Cups. Melt in the microwave in 20-second intervals, stir until creamy.
  • Add in the cream cheese. Using an electric mixer, beat for 2-3 minutes until creamy.
  • Add eggs, one at a time, mixing well.
  • Add melted butter and beat until combined.
  • Add in the confectioners' sugar and mix until incorporated.
  • Pour the peanut butter mixture over the chopped Reese's Peanut Butter Cups and bake for 35-40 minutes. Do not overbake; the center will be slightly jiggly, but it will be done.
  • Remove the bars from the oven. Let the bars cool completely before refrigerating for about 2 hours. After the bars are chilled, cut into squares and enjoy! Note: Bars will still be gooey after chilling.
