Perfect for quick gatherings, this dump cake requires minimal effort and bakes into a gooey, chocolatey treat with a crunchy Oreo topping.

Ingredients

Ingredients

  • 24 Oreo cookies, divided use (6 cookies are used for topping)
  • 1 (14 ounce) can sweetened condensed milk
  • 1 (8 ounce) tub whipped topping (Cool Whip), thawed
  • 1 (15.25 ounce) box chocolate fudge cake mix
  • ½ cup salted butter, cold and thinly sliced

Instructions

  1. Preheat and Prepare Pan: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan or a similarly sized pan with non-stick spray to prevent sticking.
  2. Layer Oreos: Arrange 18 to 22 Oreo cookies in a single layer on the bottom of the prepared baking pan. The exact number may vary depending on your pan size.
  3. Add Sweetened Condensed Milk: Pour the entire can of sweetened condensed milk evenly over the Oreo cookies to saturate the layer beneath.
  4. Spread Whipped Topping: Gently spread the thawed whipped topping over the sweetened condensed milk, covering the surface evenly.
  5. Sprinkle Cake Mix: Evenly distribute the dry chocolate fudge cake mix over the whipped topping layer, ensuring it covers the top uniformly.
  6. Add Butter Slices: Arrange the cold, thin slices of salted butter evenly on top of the cake mix to enrich the dessert as it bakes.
  7. Top with Crushed Oreos: Chop the remaining 6 Oreo cookies into small pieces and sprinkle them evenly over the butter slices for an added crunchy topping.
  8. Bake the Cake: Place the pan in the preheated oven and bake for 35 to 40 minutes until the top is set and bubbling around the edges.
  9. Serve Warm: Use a large serving spoon to scoop the dump cake and serve immediately while warm for the best texture, as it becomes firmer and harder to scoop once cooled.

Notes

  • Make sure to serve the cake warm as it becomes difficult to scoop when cooled.
  • You can substitute salted butter with unsalted butter plus a pinch of salt if preferred.
  • For a richer flavor, try adding a handful of chopped nuts or chocolate chips on top before baking.
  • If you do not have a 9×13-inch pan, use a similar-sized baking dish, adjusting the number of Oreos accordingly to cover the base.
  • This dump cake does not require any mixing or additional utensils, making it perfect for quick, no-fuss desserts.
