Ingredients

Scale

Dry Ingredients

  • 1 box chocolate cake mix (devil’s food or any chocolate cake mix)

Wet Ingredients

  • 1/2 cup melted real butter
  • 1 1/2 cups milk (whole milk recommended)
  • 1 cup peanut butter (creamy or crunchy, room temperature)

Toppings

  • 1 cup mini peanut butter cups
  • 1/2 cup semi-sweet chocolate chips (milk chocolate works too)

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with cooking spray or butter to prevent sticking.
  2. Spread Peanut Butter Layer: Let the peanut butter sit at room temperature for 30 minutes to soften. Then spread it evenly across the bottom of the greased baking dish using a butter knife or offset spatula. It doesn’t need to be perfect, just full coverage.
  3. Mix Cake Batter: In a large bowl, combine the chocolate cake mix, melted butter, and milk. Whisk until smooth with no dry pockets, but it’s okay to have a few tiny lumps. The batter should be thick but pourable. Adjust consistency by adding a splash more milk if too thick or a tablespoon of flour if too thin.
  4. Assemble Cake: Pour the chocolate batter over the peanut butter layer in the baking dish, allowing it to spread evenly.
  5. Add Toppings: Sprinkle the mini peanut butter cups and chocolate chips evenly over the top. They will sink slightly during baking, creating pockets of melted goodness.
  6. Bake: Place the baking dish in the oven and bake for 35-40 minutes. The cake is done when the edges pull away slightly and a toothpick inserted in the center comes out with moist crumbs, not wet batter.
  7. Cool and Serve: Allow the cake to cool in the pan for at least 15 minutes to let the layers set, ensuring clean slices. Serve warm, optionally with a scoop of vanilla ice cream for extra indulgence.

Notes

  • Let peanut butter come to room temperature before spreading for easier application.
  • Check the cake at 30 minutes as oven temperatures vary to prevent overbaking.
  • Use mini peanut butter cups for even melting; regular-sized ones may not melt properly.
  • Cooling is essential for neat slices and better texture.
  • For a richer dessert, serve with vanilla ice cream.
