Ingredients

Scale

Main Ingredients

  • 25 Oreo cookies
  • 14 ounce can sweetened condensed milk
  • 8 ounce whipped topping (Cool Whip), thawed but not frozen
  • 15¼ ounce chocolate cake mix (dry)
  • ½ cup sweet salted butter (1 stick), melted

Instructions

  1. Preheat oven: Preheat your oven to 350°F (175°C) to prepare for baking the dump cake.
  2. Prepare the baking dish: Lightly grease a 9×13 inch baking dish to prevent sticking.
  3. Layer Oreos: Spread the whole Oreo cookies evenly in the bottom of the prepared dish.
  4. Add sweetened condensed milk: Pour the can of sweetened condensed milk evenly over the Oreos, allowing it to soak slightly.
  5. Sprinkle cake mix: Evenly sprinkle the dry chocolate cake mix over the condensed milk and Oreos, covering them completely.
  6. Drizzle melted butter: Pour the melted salted butter evenly over the top of the cake mix to moisten and create a crisp topping.
  7. Bake the cake: Place the dish in the preheated oven and bake for 40 to 45 minutes until the top is bubbly and golden brown.
  8. Cool and add topping: Remove from oven and allow the cake to cool completely. Once cool, spread the whipped topping evenly over the surface.
  9. Chill before serving: Refrigerate the cake for at least 1 hour before slicing and serving to allow it to set properly and enhance flavors.

Notes

  • You can substitute Oreos with any chocolate sandwich cookies if preferred.
  • Make sure the whipped topping is thawed but chilled for best spreading texture.
  • For a deeper chocolate flavor, try using a devil’s food cake mix instead of regular chocolate.
  • Store leftovers covered in the refrigerator and consume within 3 to 4 days for freshness.
  • Optional: sprinkle some crushed Oreos on top of the whipped topping for an extra decorative touch.
