Ingredients

Scale

Dry Ingredients

  • 1 box chocolate cake mix

Wet Ingredients

  • 1 cup smooth peanut butter
  • 1 can (14 oz) sweetened condensed milk
  • 1/2 cup caramel sauce

Toppings

  • 1 1/2 cups chopped mini peanut butter cups, divided
  • 1/2 cup chocolate chips or melting chocolate, melted
  • 1/4 cup crushed graham crackers or cookies (optional)

Instructions

  1. Preheat and Prepare: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish to prevent sticking.
  2. Layer Cake Mix: Evenly pour the dry chocolate cake mix into the prepared baking dish. Do not stir or mix the dry ingredients.
  3. Add Sweetened Condensed Milk and Peanut Butter: Drizzle the sweetened condensed milk and melted peanut butter evenly over the top of the dry cake mix. Use a spoon to lightly swirl the mixture, creating a marbled effect.
  4. Add Peanut Butter Cups and Caramel: Sprinkle half of the chopped mini peanut butter cups over the top, then drizzle with caramel sauce for added sweetness and texture.
  5. Bake: Bake the cake uncovered for 30 to 35 minutes. The edges should be set while the center remains slightly gooey to keep a rich, decadent texture.
  6. Cool and Top: Allow the cake to cool for 10 minutes. Then, top it with the remaining chopped peanut butter cups, drizzle melted chocolate over the top, and sprinkle crushed graham crackers or cookies if using.
  7. Serve: Serve the dump cake warm for the best flavor and texture, optionally accompanied by ice cream or whipped cream for an extra indulgent dessert.

Notes

  • Do not stir the cake mix before baking to maintain the dump cake texture.
  • Use smooth peanut butter for better drizzling and marbling.
  • Leftover cake can be stored in an airtight container at room temperature for up to 2 days or refrigerated for up to 5 days.
  • For a gluten-free version, use a gluten-free chocolate cake mix and gluten-free crushed cookies.
  • Serving warm enhances the gooey texture, but it can also be enjoyed at room temperature.
