Essential Ingredients for Your Decadent Creation

You'll be amazed at how a handful of pantry staples transforms into such a spectacular dessert!

  • Chocolate Cake Mix: A standard box of your favorite chocolate cake mix provides the perfect foundation. Devil's Food or chocolate fudge works wonderfully.
  • Creamy Peanut Butter: The star of the show! Make sure it's creamy for easy mixing and melting.
  • Milk: Adds moisture and helps bind the cake mix for a tender crumb.
  • Semi-Sweet Chocolate Chips: Extra pockets of rich chocolate for that irresistible flavor.
  • Chopped Mini Peanut Butter Cups: These are the magic makers, melting into gooey pockets of peanut butter bliss throughout the cake.
  • Unsalted Butter, Melted: Crucial for the classic dump cake crust and adding incredible richness.

How to Make Your Peanut Butter Cup Dump Cake

Creating this decadent dessert is incredibly straightforward. Just follow these simple steps for a perfect, gooey cake every time!

  1. Prepare Your Pan and Oven: Preheat your oven to 350°F (175°C). Lightly grease a 9x13 inch baking dish.
  2. Combine Batter Ingredients: In a large bowl, whisk together the chocolate cake mix, slightly melted creamy peanut butter, and milk until just combined. The batter will be thick and rich.
  3. Spread the Batter: Pour the peanut butter chocolate batter into your prepared baking dish and spread it evenly across the bottom.
  4. Add Chocolate Chips: Evenly sprinkle the semi-sweet chocolate chips over the cake batter.
  5. Distribute Peanut Butter Cups: Scatter the chopped mini peanut butter cups over the chocolate chips.
  6. Drizzle with Butter: Pour the melted unsalted butter evenly over the entire surface of the cake. Resist the urge to stir! This melted butter creates that signature dump cake crust.
  7. Bake to Perfection: Place the dish in the preheated oven and bake for 45-50 minutes, or until the edges are bubbly and the top is lightly golden. A toothpick inserted into the cake part (avoiding melted candy) should come out mostly clean.
  8. Cool and Serve: Let the cake cool for at least 15-20 minutes before serving. It will be incredibly gooey and warm, making every bite an absolute delight!

Tips for Dump Cake Perfection

  • Don't Overmix: When combining the cake mix, peanut butter, and milk, mix just until combined. A few lumps are perfectly fine and will bake out.
  • Even Distribution is Key: Try to spread the chocolate chips and peanut butter cups as evenly as possible so every slice gets a good share of the goodies.
  • Serve Warm: While delicious at any temperature, this dump cake truly shines when served warm, straight from the oven, allowing all those chocolate and peanut butter pockets to be wonderfully melted.
  • Customize Your Toppings: A scoop of vanilla bean ice cream, a dollop of fresh whipped cream, or a drizzle of chocolate fudge sauce can elevate this cake to an even more luxurious experience.

Storage and Reheating

If you happen to have any leftovers (a rare occurrence with this cake!), store them in an airtight container at room temperature for up to 3 days. For extended freshness, especially if you added dairy toppings, refrigerate for up to 5 days. To reheat, individual slices can be warmed in the microwave for 15-20 seconds until delightfully gooey again.
