Introduction
This Oreo Dump Cake is a simple, no-fuss dessert that delivers rich chocolate flavor and creamy texture with minimal effort. Perfect for a last-minute treat, it combines crushed Oreos, sweetened condensed milk, whipped topping, and chocolate cake mix for a crowd-pleasing indulgence.

Ingredients
- 24 Oreo cookies, divided (6 cookies for topping)
- 14 ounce can sweetened condensed milk
- 8 ounce tub whipped topping (Cool Whip), thawed
- 15.25 ounce box chocolate fudge cake mix
- 1/2 cup salted butter, cold and thinly sliced
Instructions
- Step 1: Preheat the oven to 350°F and grease a 9×13-inch baking pan with non-stick spray.
- Step 2: Arrange the Oreos in a single layer in the pan. Depending on the pan size, use about 18 to 22 cookies.
- Step 3: Pour the sweetened condensed milk evenly over the Oreos, then spread the thawed whipped topping over the milk layer.
- Step 4: Sprinkle the dry chocolate cake mix evenly over the whipped topping.
- Step 5: Arrange the cold, thinly sliced butter evenly over the cake mix.
- Step 6: Chop the remaining 6 Oreos and sprinkle them on top of the butter slices.
- Step 7: Bake for 35 to 40 minutes until golden and bubbly. Serve warm using a large serving spoon, as the cake is easier to scoop when hot.
Tips & Variations
- For extra richness, try using full-fat whipped topping or homemade whipped cream instead of Cool Whip.
- Swap salted butter for unsalted and add a pinch of salt to balance flavors.
- Add a handful of chopped nuts between layers for crunch.
- Use mini Oreos for a different texture and fun presentation.
Storage
Store leftover cake covered in the refrigerator for up to 3 days. Reheat gently in the microwave for 20-30 seconds to soften before serving, as the cake becomes firm when cold.

FAQs
Can I use a different brand of whipped topping?
Yes, any brand or homemade whipped topping can be used as long as it is thawed and spreadable.
Is it necessary to bake the dump cake immediately after assembling?
It’s best to bake the cake soon after assembling to ensure the butter melts properly and the layers combine well. Delaying baking might affect texture and make it harder to bake evenly.

- 18–22 Oreo cookies (about 24 total, with 6 reserved for topping)
Wet Ingredients
- 14 ounce can sweetened condensed milk
- 8 ounce tub whipped topping (Cool Whip), thawed
Dry Ingredients
- 15.25 ounce box chocolate fudge cake mix
Fat
- 1/2 cup salted butter, cold and thinly sliced
Topping
- 6 Oreo cookies, chopped
Instructions
- Preheat and Prepare Pan: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan or similar-sized pan with non-stick spray to prevent sticking.
- Layer Oreos: Arrange 18 to 22 Oreo cookies in a single layer evenly across the bottom of the prepared pan, adjusting quantity to fit your pan size.
- Add Sweetened Condensed Milk: Pour the entire can of sweetened condensed milk evenly over the Oreo layer, ensuring it’s fully covered.
- Spread Whipped Topping: Spread the thawed whipped topping gently but thoroughly over the condensed milk layer for a smooth layer.
- Sprinkle Cake Mix: Evenly sprinkle the dry chocolate fudge cake mix over the whipped topping layer, covering the surface completely.
- Top with Butter Slices: Arrange thin slices of cold salted butter evenly on top of the cake mix layer to add richness and moisture.
- Add Chopped Oreos: Chop 6 Oreo cookies and sprinkle the pieces evenly over the butter slices to create a crunchy, chocolaty topping.
- Bake: Bake the cake in the preheated oven for 35 to 40 minutes until the top is melted and bubbly and the butter slices have melted through the cake mix.
- Serve Warm: Scoop and serve the cake immediately while it is warm and easy to spoon. It hardens as it cools, making it more difficult to serve.
Notes
- Use a 9×13-inch baking pan for best results; adjust Oreo quantity based on pan size.
- Serve immediately while warm for the best texture and flavor.
- The cake becomes firmer as it cools, so reheating before serving is recommended if not served right away.
- You can substitute salted butter with unsalted and add a pinch of salt if preferred.
- Whipped topping should be completely thawed before spreading for even layering.
