Ingredients

  • 1 box chocolate cake mix
  • 1 cup peanut butter room temperature for easy spreading
  • ½ cup melted butter
  • 1 ½ cups milk
  • 1 cup mini peanut butter cups
  • ½ cup chocolate chips

Instructions

  • Set oven to 350°F (175°C). Grease a 9×13-inch baking dish with cooking spray or butter to prevent sticking.
  • Spread peanut butter evenly across the bottom of the greased pan. It doesn’t have to be perfect—just make sure the bottom is covered.
  • In a large bowl, whisk together cake mix, melted butter, and milk until smooth. Batter should be thick but pourable. If too thin, add 1 tablespoon flour; if too thick, add a splash more milk.
  • Pour the batter over the peanut butter layer. Sprinkle mini peanut butter cups and chocolate chips evenly across the top.
  • Bake for 35–40 minutes. The cake is done when edges pull away slightly and a toothpick inserted in the center comes out with moist crumbs. Cool at least 15 minutes before slicing.
