Ingredients

Scale

Cookies

  • 25 Oreo cookies
  • 8 Oreo cookies, chopped (for topping)

Wet Ingredients

  • 14 ounce can sweetened condensed milk
  • 8 ounce whipped topping (Cool Whip), thawed but not frozen
  • ½ cup salted butter, sliced

Dry Ingredients

  • 15¼ ounce chocolate cake mix

Instructions

  1. Preheat oven: Preheat your oven to 350°F (175°C) to ensure it reaches the correct temperature for baking the cake evenly.
  2. Prepare the baking pan: Grease a 9×13 inch baking pan with cooking spray to prevent sticking and make cleanup easier.
  3. Layer the Oreos: Arrange 25 Oreo cookies in a single layer evenly across the bottom of the prepared baking dish.
  4. Add sweetened condensed milk: Pour the entire can of sweetened condensed milk evenly over the Oreo cookies, ensuring good coverage for moisture and sweetness.
  5. Spread whipped topping: Gently spread the 8 ounces of whipped topping over the cookie and milk layer, creating a smooth and even layer.
  6. Sprinkle cake mix: Evenly sprinkle the dry chocolate cake mix over the whipped topping layer, covering the surface completely.
  7. Add butter slices: Arrange the ½ cup sliced salted butter evenly on top of the cake mix. The butter will melt during baking to moisten and flavor the cake.
  8. Add chopped Oreos: Chop 8 additional Oreo cookies and sprinkle them evenly over the top for extra texture and Oreo flavor.
  9. Bake the cake: Bake in the preheated oven for 35 to 40 minutes, or until the edges are bubbly and the top is set.
  10. Serve: Serve the dump cake warm, optionally topped with ice cream and chocolate sauce for a decadent dessert experience.

Notes

  • Use salted butter to balance the sweetness and enhance flavor; if using unsalted, add a pinch of salt to the cake mix layer.
  • Do not thaw the whipped topping completely—just thaw enough so it spreads easily without melting.
  • Be sure to grease the pan well to avoid sticking, especially with condensed milk in the recipe.
  • This recipe can be customized by using different flavored cake mixes or adding nuts for extra crunch.
  • Leftovers can be stored covered in the refrigerator for up to 3 days and reheated before serving.
