What is a Dump Cake?

A dump cake gets its name from the preparation method. You literally “dump” the ingredients into a baking dish without any mixing. Typically, this involves a layer of fruit or filling, followed by a dry cake mix, and then topped with melted butter. The butter melts down, combines with the cake mix, and creates a delicious, cobbler-like topping. Our version swaps fruit for rich, chocolatey peanut butter cups for an even more decadent twist.

Ingredients You’ll Need

The beauty of this recipe lies in its simplicity. Here’s what you’ll need:

  • Chocolate Cake Mix: One standard box of devil’s food or chocolate fudge cake mix is the perfect base.
  • Peanut Butter Cups: The star of the show! You’ll need about two cups of chopped peanut butter cups.
  • Butter: Salted butter, melted, creates the rich, gooey topping.
  • Milk: Whole milk helps bring everything together, ensuring a moist cake.
  • Chocolate Chips: A handful of semi-sweet chocolate chips adds an extra layer of chocolatey goodness.

How to Make Peanut Butter Cup Dump Cake

Making this cake is as simple as 1-2-3. Just layer and bake!

  1. Preheat and Prep: Start by preheating your oven to 350°F (175°C). Lightly grease a 9×13 inch baking dish.
  2. Layer the Candy: Spread the chopped peanut butter cups evenly across the bottom of the prepared dish. Sprinkle the chocolate chips over the top.
  3. Add the Cake Mix: Pour the dry chocolate cake mix directly over the candy layer. Use a spatula to spread it evenly, but do not mix.
  4. Pour the Liquids: Gently pour the milk over the cake mix, followed by the melted butter. Try to cover as much of the surface as possible.
  5. Bake to Perfection: Bake for 35-40 minutes, or until the top is set and the edges are bubbly. Let it cool for about 10 minutes before serving. It’s best served warm, maybe with a scoop of vanilla ice cream!

Tips for the Best Dump Cake

This recipe is nearly foolproof, but a few tips can make it even better.

  • Don’t Mix: Resist the urge to stir the ingredients! The layers are essential for creating the perfect texture.
  • Even Topping: Ensure the melted butter is drizzled as evenly as possible over the cake mix for a consistent, delicious crust.
  • Use Quality Candy: The better the peanut butter cups, the better the final cake will taste. For another amazing dessert check out these German Chocolate Brownies.

Variations and Substitutions

  • Add Nuts: Sprinkle a cup of chopped peanuts or pecans over the candy layer for a satisfying crunch.
  • Try Other Candies: Feel free to substitute other chopped candy bars like Snickers or Milky Way.
