Ingredients

Scale

For the Cake

  • 1 box chocolate cake mix (Devil’s Food preferred, any chocolate works)
  • 1/2 cup melted real butter
  • 1 1/2 cups milk (whole milk recommended)

For the Peanut Butter Layer

  • 1 cup peanut butter (creamy recommended for smooth layers)

Toppings

  • 1 cup mini peanut butter cups
  • 1/2 cup semi-sweet chocolate chips (milk chocolate can be used)

Other

  • Cooking spray or butter, for greasing the pan

Instructions

  1. Preheat Oven and Prepare Baking Dish. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with cooking spray or butter to prevent sticking.
  2. Prepare Peanut Butter Layer. Let the peanut butter sit at room temperature for about 30 minutes to soften. Spread the creamy peanut butter evenly across the bottom of the greased pan using a butter knife or offset spatula, ensuring full coverage but not needing to be perfect.
  3. Mix Cake Batter. In a large bowl, combine the chocolate cake mix, melted butter, and milk. Whisk thoroughly until smooth with no dry spots. The batter should be thick but pourable, similar to pancake batter. Adjust thickness by adding a little more milk if too thick, or a tablespoon of flour if too thin.
  4. Assemble Cake. Pour the prepared chocolate batter evenly over the peanut butter layer in the baking dish, allowing it to spread out naturally.
  5. Add Toppings. Sprinkle the mini peanut butter cups and chocolate chips evenly over the top of the batter. These will slightly sink and melt during baking, adding gooey pockets of flavor.
  6. Bake the Cake. Place the baking dish in the preheated oven and bake for 35-40 minutes. Check doneness by inserting a toothpick in the center—the toothpick should come out with moist crumbs but no wet batter. The edges should start to pull away slightly from the pan.
  7. Cool Before Serving. Allow the cake to cool in the pan for at least 15 minutes to let the layers set for cleaner slicing and a better texture.

Notes

  • Let peanut butter come to room temperature for easier spreading and smoother layering.
  • Check your oven temperature, and start testing for doneness at 30 minutes if it tends to run hot.
  • Use mini peanut butter cups instead of regular-sized ones for even melting and better distribution.
  • Cooling the cake before serving makes slicing neater and layers more defined.
  • Serve with a scoop of vanilla ice cream for an indulgent treat.
