Ingredients

Scale

Cake Mix

  • 1 box yellow or vanilla cake mix (about 15.25 oz)

Peanut Butter Cups

  • 1012 regular-sized peanut butter cups, unwrapped and roughly chopped

Butter

  • 1 cup (2 sticks) unsalted butter, melted

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) to ensure even baking.
  2. Prepare Baking Dish: Lightly grease a 9×13 inch baking dish to prevent sticking and make cleanup easier.
  3. Layer Cake Mix: Evenly sprinkle the dry cake mix over the bottom of the baking dish in a thin, uniform layer to create the cake base.
  4. Add Peanut Butter Cups: Distribute chopped peanut butter cups evenly over the cake mix layer, ensuring every bite will have melty peanut butter and chocolate flavor.
  5. Pour Melted Butter: Carefully drizzle the melted butter over the top, covering the peanut butter cups and cake mix thoroughly to bind everything and create moist, golden results.
  6. Bake the Cake: Place the baking dish in the preheated oven and bake for 35 to 40 minutes, or until the cake is bubbly around the edges and set in the center.
  7. Cool and Serve: Let the dump cake cool for about 15 minutes before serving to allow it to firm up slightly and enhance flavor melding. Serve warm or at room temperature, optionally with vanilla ice cream or whipped cream.

Notes

  • Use chunks or chopped peanut butter cups to get melted pockets of peanut butter and chocolate throughout.
  • For extra richness, sprinkle a pinch of sea salt on top before baking to balance sweetness.
  • Leftovers can be stored covered in the refrigerator for up to 3 days; reheat gently before serving.
  • Feel free to swap yellow cake mix with chocolate or spice cake mix for a flavor twist.
  • This dessert is naturally vegetarian but not suitable for vegan due to butter and possible dairy in the cake mix.
