Ingredients

Scale

Peanut Butter Layer

  • 1 cup creamy peanut butter

Chocolate Candy Layer

  • 1.5 cups chopped peanut butter cups, plus extra for garnish

Condensed Milk Layer

  • 1 can (400 g) sweetened condensed milk

Dry Cake Mix Layer

  • 1 box (432 g) chocolate cake mix, dry

Butter and Chocolate Topping

  • 115 g unsalted butter, melted
  • 175 g milk chocolate chips

Optional for Serving

  • Whipped cream or vanilla ice cream

Instructions

  1. Prepare baking dish: Preheat your oven to 175°C (350°F). Grease a 23×33 cm (9×13-inch) baking dish with butter or non-stick spray to prevent sticking.
  2. Layer peanut butter: Spread the creamy peanut butter evenly over the bottom of the prepared baking dish to form the first layer of the dessert.
  3. Add candy layer: Sprinkle half of the chopped peanut butter cups evenly over the peanut butter layer for a rich candy flavor.
  4. Add condensed milk: Pour the sweetened condensed milk evenly over the candy layer to add creaminess and sweetness.
  5. Add cake mix: Sprinkle the dry chocolate cake mix evenly over the top without mixing it into the other layers, which creates a unique texture.
  6. Drizzle butter: Drizzle the melted unsalted butter evenly over the cake mix layer to help it bake into a crispy topping.
  7. Top with chocolate and candy: Sprinkle the milk chocolate chips along with the remaining chopped peanut butter cups over the top for added chocolatey goodness.
  8. Bake the cake: Place the dish in the preheated oven and bake for 35–40 minutes or until the top layer is bubbly and slightly crisp, indicating it is cooked through.
  9. Cool and serve: Allow the dump cake to cool slightly before serving. Enhance the dessert by topping with whipped cream or a scoop of vanilla ice cream, if desired.

Notes

  • Do not stir the layers after adding the dry cake mix; it cooks into a delightful layered texture.
  • Use a 23×33 cm (9×13-inch) baking dish to ensure even cooking.
  • For easier slicing, let the cake cool for at least 10 minutes before serving.
  • This dessert pairs perfectly with vanilla ice cream or whipped cream to balance its rich flavors.
  • Store leftovers covered in the refrigerator for up to 3 days.
