Ingredients

Scale

Peanut Butter Layer

  • 1 cup creamy or crunchy peanut butter (room temperature)

Cake Batter

  • 1 box chocolate cake mix (devil’s food recommended)
  • 1/2 cup melted real butter
  • 1 1/2 cups milk (whole milk preferred)

Topping

  • 1 cup mini peanut butter cups
  • 1/2 cup semi-sweet chocolate chips

Instructions

  1. Preheat Oven 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: Take the room temperature peanut butter and spread it evenly over the bottom of the greased baking dish using a butter knife or offset spatula. Aim to cover the entire base for a fudgy ribbon effect in the final cake.
  3. Mix Cake Batter: In a large mixing bowl, combine the chocolate cake mix, melted butter, and milk. Whisk together until smooth but don’t overmix; a few tiny lumps are okay. The batter should be thick yet pourable; adjust thickness by adding a splash of milk if too thick or a tablespoon of flour if too thin.
  4. Assemble Cake: Pour the chocolate batter evenly over the peanut butter layer. Then sprinkle the mini peanut butter cups and chocolate chips evenly on top. They will sink slightly during baking creating pockets of melty goodness.
  5. Bake: Place the baking dish in the preheated oven and bake for 35-40 minutes. The cake is done when the edges pull away from the pan and a toothpick inserted comes out with moist crumbs but no wet batter.
  6. Cool and Serve: Allow the cake to cool for at least 15 minutes before serving to let the layers set. Enjoy warm or at room temperature for maximum gooey delight.

Notes

  • Let peanut butter sit at room temperature for 30 minutes before spreading for easier spreading.
  • Use real butter melted for best flavor and texture.
  • If you prefer crunchier texture, opt for crunchy peanut butter.
  • Add a tablespoon of flour if batter is too thin to maintain desired consistency.
  • Store leftovers covered at room temperature for up to 2 days or refrigerate for longer freshness.
