Tips & Variations
- For added texture, try mixing some chopped nuts into the layers or on top before baking.
- If you prefer a less sweet dessert, reduce the amount of sweetened condensed milk slightly.
- Use regular whipped cream instead of Cool Whip for a fresher taste, but spread it quickly to avoid melting.
- Try adding a layer of mini marshmallows before the butter for a gooey surprise.
Storage

FAQs
Can I use a different type of cookie instead of Oreos?
Yes, you can substitute the Oreos with your favorite chocolate sandwich cookies or even chocolate chip cookies. Just be aware that the flavor and texture will vary slightly.
Is it necessary to use both cold and melted butter?
Using cold butter slices helps create pockets of buttery richness as the cake bakes, while melted butter drizzled on top ensures the dry cake mix moistens properly. Both contribute to the classic dump cake texture.

Ingredients
Cookies
- 20–28 Oreo cookies, divided
Wet Ingredients
- 14 oz. sweetened condensed milk
- 8 oz. cool whip, thawed
- ¼ – ½ cup (57 – 113 g) butter, melted
Dry Ingredients
- 15.25 oz. chocolate fudge cake mix
Other
- ½ cup (113 g) cold butter, evenly sliced
Instructions
- Prep: Preheat your oven to 350°F (177°C). Lightly grease an 11 x 7-inch or 9 x 13-inch baking dish using about a tablespoon of butter to prevent sticking.
- Layer Oreos: Evenly spread 18 to 22 whole chocolate Oreo cookies across the bottom of the greased baking dish, depending on your pan size.
- Add Sweetened Condensed Milk: Pour the 14 oz. of sweetened condensed milk uniformly over the Oreo cookie layer, ensuring full coverage to enable the cookies to soak and soften during baking.
- Spread Cool Whip: Evenly spread 8 oz. of thawed cool whip over the sweetened condensed milk-covered cookies to add a creamy, airy layer to the dessert.
- Apply Cake Mix: Sprinkle the entire 15.25 oz. of chocolate fudge cake mix evenly over the cool whip layer to create the cake topping.
- Add Butter: Arrange slices of cold butter (½ cup/113 g) evenly over the cake mix layer, covering as much surface area as possible. Then drizzle the melted butter (¼ to ½ cup) between the cold butter slices to ensure even moisture and richness.
- Top with Crushed Oreos: Sprinkle approximately 4 to 6 crushed Oreo cookies on top for extra crunch and flavor.
- Bake: Place the pan in the preheated oven and bake for 35 to 40 minutes. The edges will bubble and the sweetened condensed milk will caramelize slightly, indicating the cake is done.
- Cool and Serve: Let the dump cake cool for about 5 minutes. Serve warm by scooping into bowls, optionally topping with vanilla ice cream for an indulgent dessert experience.
Notes
- Pan size can be either 11 x 7 inches or 9 x 13 inches — adjust the number of Oreos accordingly.
- Ensure the butter is both sliced cold and melted for the best texture and flavor distribution.
- The dessert is best served warm but can also be enjoyed at room temperature.
- Adding ice cream on top elevates the dessert, but it’s delicious on its own as well.
- Store leftovers covered in the refrigerator for up to 3 days.
