Ingredients

  • 1 box chocolate fudge cake mix
  • 1 (3.9 oz) box instant chocolate pudding mix
  • 1 1/2 cups milk
  • 1/2 cup creamy peanut butter
  • 1 cup semi-sweet chocolate chips
  • 1 1/2 cups mini peanut butter cups, chopped (plus more for topping)
  • 1 (14 oz) can sweetened condensed milk
  • 1 cup heavy cream
  • 1 cup dark chocolate chips (for ganache)

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×13-inch baking pan.
  2. In a bowl, mix cake mix, pudding mix, and milk until smooth. Pour into pan.
  3. Add spoonfuls of peanut butter on top and swirl gently with a knife. Sprinkle with chocolate chips and chopped peanut butter cups.
  4. Bake 30–35 minutes, until center is set. While warm, poke holes over the cake and drizzle sweetened condensed milk.
  5. For ganache: Heat cream until simmering, then pour over dark chocolate chips. Stir until smooth.
  6. Pour ganache over cooled cake and top with more chopped peanut butter cups. Chill 30 minutes or serve warm.

Notes

  • Swap semi-sweet chocolate chips with white or milk chocolate for variation.
  • Use crunchy peanut butter for added texture.
  • Add chopped peanuts or sprinkle sea salt on top for a richer flavor contrast.
  • Can be served warm for a gooey texture or chilled for a brownie-like finish.
