Ingredients

You only need five ingredients to make this incredible treat:

  • Oreo Cookies: The star of the show! They add rich chocolate flavor and crunchy texture.
  • Sweetened Condensed Milk: This thick, syrupy milk adds luscious creaminess and sweetness.
  • Whipped Topping: It gives a light, creamy layer to balance out the rich flavors.
  • Chocolate Fudge Cake Mix: A box of store-bought cake mix is the easy secret to the gooey chocolate top layer. 
  • Salted Butter: Sliced butter dotted on top melts into the cake mix. It’s the perfect finishing touch.

How to Make Oreo Dump Cake

Follow these steps to make this easy-peasy cake:

  1. Prep the oven and pan. Preheat the oven to 350°F. Grease a 9×13-inch baking pan with non-stick cooking spray.
  2. Layer the Oreo cookies. Arrange 18-20 Oreo cookies in a single layer on the bottom of the prepared pan. Cover as much surface area as possible.
  3. Pour the condensed milk. Pour the sweetened condensed milk evenly over the layer of Oreo cookies.
  4. Spread the whipped topping. Spread the whipped topping over the sweetened condensed milk in an even layer.
  5. Add the cake mix. Sprinkle the dry chocolate fudge cake mix evenly over the whipped topping layer.
  6. Top with butter. Arrange the butter slices in a single layer on top of the cake mix. Cover as much surface area as possible.
  7. Sprinkle the chopped Oreos. Roughly chop the remaining 4-6 Oreo cookies. Sprinkle them on top of the butter layer.
  8. Bake the cake. Bake in the preheated oven for 35-40 minutes. The top should be set, and the butter should absorb into the cake mix.
  9. Serve warm. Remove from the oven and let cool for 5-10 minutes. Serve warm, scooping out portions with a large spoon. If desired, top individual servings with a scoop of vanilla ice cream and a drizzle of chocolate syrup.

Tips For the Best Oreo Dump Cake

This cake is impossible to mess up. But these tips take it over the top! 

  • Use parchment paper. If you don’t think you’ll eat all this in one, line the dish with parchment so it’s easy to scoop when cool.
  • Bust up any lumps. Use a fork to break up any large lumps in the cake mix for an even distribution and better texture.
  • Be even with the butter. Place the butter slices evenly across the top of the cake mix. This ensures the top layer bakes into a gooey, brownie-like consistency.
  • Bake until bubbly. You’ll know the cake is done when the top is golden brown and the edges are bubbly.
  • Get tasty with toppings. Top individual servings with a scoop of vanilla ice cream and a drizzle of chocolate syrup. Or, try caramel syrup for extra flavor.
  • Have fun and experiment. Try different flavors of Oreo cookies or cake mix to customize the recipe and create new variations.

How to Store

If you have leftover dump cake, here’s how to keep it fresh:

To Store: Keep leftover cake covered in the refrigerator for up to 3 days. Ensure the cake is completely cooled before covering and storing.

To Freeze: Tightly wrap the cooled cake in plastic wrap, followed by a layer of aluminum foil. Store it in the freezer for up to 2 months. When ready to serve, thaw the cake overnight in the refrigerator.

Keep in mind freezing and thawing may affect the texture of the whipped topping and Oreo cookies.

To Reheat: Reheat individual portions of the cake in the microwave for 20-30 seconds, or until warmed through. You can also reheat larger portions in a preheated oven at 350°F for 10-15 minutes.
