Ingredients

Scale

Ingredients

  • 1 box (15.25 oz) Devil’s Food cake mix
  • 1.5 cups whole milk
  • 1 cup creamy peanut butter
  • 1 cup semi-sweet chocolate chips
  • 1/2 cup (1 stick) unsalted butter, melted

Instructions

  1. Prepare Your Pan: Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish generously with butter or non-stick spray to prevent sticking.
  2. Layer the Ingredients: Pour the whole milk evenly into the bottom of the prepared baking dish. Sprinkle the semi-sweet chocolate chips evenly over the milk. Drop spoonfuls of creamy peanut butter evenly across the chocolate chips, creating pockets of peanut butter throughout.
  3. Dump the Cake Mix: Sprinkle the dry Devil’s Food cake mix evenly over the peanut butter and chocolate chip layer. Avoid stirring; the layers should remain separate for proper baking.
  4. Add the Butter: Pour the melted unsalted butter as evenly as possible over the entire surface of the dry cake mix layer, covering as much of the powder as possible to ensure a crisp, golden topping.
  5. Bake to Perfection: Place the baking dish in the preheated oven and bake for 35-40 minutes until the edges are bubbly and the top is slightly crisp and set.
  6. Cool and Serve: Remove from the oven and allow the cake to cool for about 15 minutes. This resting time helps the gooey center to set up slightly for easier portioning. Serve warm, optionally with a scoop of vanilla ice cream for an extra indulgent treat.

Notes

  • Do not stir the layers; the magic of a dump cake comes from the layers baking together without mixing.
  • For even butter distribution, you can use thin pats of cold butter instead of melted butter if preferred.
  • Allow the cake to rest after baking for 15-20 minutes before serving to let the center set.
  • Try adding 1/2 cup chopped peanuts or pecans for a crunchy texture.
  • Substitute some chocolate chips with peanut butter chips or replace peanut butter dollops with chopped Reese’s Peanut Butter Cups for a variation.
  • Store leftovers covered in the refrigerator for up to 4 days and reheat in the microwave for 30-45 seconds to restore gooeyness.
