Ingredients

Scale

Dry Ingredients

  • 1 box chocolate cake mix (about 430 g / 15.25 oz)
  • 1/2 cup (100 g) granulated sugar
  • 1 cup (175 g) semi-sweet chocolate chips
  • 1 1/2 cups (225 g) peanut butter cups, chopped

Wet Ingredients

  • 1 cup (250 ml) creamy peanut butter
  • 1 cup (240 ml) milk
  • 1 teaspoon (5 ml) vanilla extract
  • 1/2 cup (115 g) unsalted butter, melted
  • 1/2 cup (120 ml) heavy cream

Other

  • Pinch of salt

Instructions

  1. Preheat and Prepare: Preheat your oven to 175°C (350°F). Lightly grease a 9×13-inch baking dish to prevent sticking.
  2. Create the Peanut Butter Layer: In a mixing bowl, combine the creamy peanut butter, milk, vanilla extract, and a pinch of salt. Stir until the mixture is smooth and well blended. Spread this evenly across the bottom of the prepared baking dish.
  3. Add Chocolate Chips and Peanut Butter Cups: Sprinkle the semi-sweet chocolate chips and chopped peanut butter cups evenly over the peanut butter layer, ensuring each bite will have plenty of chocolate and peanut butter flavor.
  4. Add the Cake Mix: Evenly sprinkle the dry chocolate cake mix over the top of the chocolate and peanut butter cups. Important: do not stir or mix the layers to preserve the dump cake texture.
  5. Pour Butter and Cream: Drizzle the melted unsalted butter and heavy cream evenly over the cake mix. Try to cover as much of the dry mix as possible to help it bake evenly and moisten the cake.
  6. Add Sugar for Texture: Sprinkle the granulated sugar over the top layer. This will help create a slightly crisp and caramelized topping once baked.
  7. Bake to Perfection: Place the baking dish in the oven and bake for 40 to 45 minutes, or until the top is set, slightly crisp, and the inside remains gooey and moist.
  8. Cool and Serve: Allow the cake to cool for 10 to 15 minutes before serving. This resting time helps the layers settle and makes it easier to scoop servings.

Notes

  • Do not stir the ingredients after layering; the dump cake texture depends on distinct layers baking together.
  • Use high-quality chocolate chips for a richer taste and better melting.
  • Chop peanut butter cups evenly to allow consistent melting and texture.
  • If the cake mix appears dry in spots before baking, drizzle a little extra melted butter over those areas.
  • Serve the cake warm for best gooey texture and flavor.
  • Store leftovers in an airtight container in the refrigerator for up to 4 days or freeze for up to 2 months.
  • Reheat servings in the microwave for 20–30 seconds before enjoying.
  • For dairy-free variations, substitute plant-based butter, non-dairy milk, and dairy-free chocolate chips, ensuring the cake mix is also dairy-free.
