This Peanut Butter Cup Dump Cake is a decadent, easy-to-make dessert perfect for peanut butter lovers.

Ingredients

Scale

Cake Layer

  • 1 box yellow cake mix
  • 1/2 cup butter, melted

Candy and Filling

  • 1 cup creamy peanut butter
  • 1 can (14 oz) sweetened condensed milk
  • 1 cup mini peanut butter cups, chopped
  • 1 cup chocolate chips
  • 1 cup chopped Reese’s or other peanut butter candies

Optional Topping

  • Chocolate syrup (for drizzling)

Instructions

  1. Preheat the Oven: Set your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish to prevent sticking.
  2. Layer the Candies: Evenly scatter the chopped mini peanut butter cups and chocolate chips across the bottom of the prepared baking dish, ensuring a uniform candy base.
  3. Add Sweetened Condensed Milk: Drizzle the entire can of sweetened condensed milk evenly over the candy layer, which adds gooey sweetness as it bakes.
  4. Dollop Peanut Butter: Spoon dollops of creamy peanut butter throughout the baking dish on top of the condensed milk layer, distributing it randomly for pockets of peanut butter flavor.
  5. Sprinkle Cake Mix: Without stirring, sprinkle the yellow cake mix evenly over the entire dish to create the cake topping that will absorb the flavors below.
  6. Pour Melted Butter: Pour the melted butter evenly over the cake mix, saturating it to help it bake into a moist, golden crust.
  7. Bake: Place the dish in the oven and bake for 40–45 minutes, or until the top is golden brown and bubbling, indicating it’s cooked through.
  8. Cool and Finish: Allow the cake to cool slightly before topping it with the extra chopped peanut butter candies and an optional drizzle of chocolate syrup for extra decadence.

Notes

  • Do not stir the layers once assembled to maintain the ‘dump cake’ texture with distinct layers.
  • The dish is very rich; serving in smaller portions is recommended.
  • Use creamy peanut butter for smooth dollops; chunky peanut butter will alter texture.
  • Let the cake cool for at least 10 minutes before serving to allow it to set.
  • Store leftovers covered at room temperature for up to 2 days or refrigerate for longer freshness.
