Tips & Variations
- For extra crunch, add chopped nuts on top before baking.
- Use reduced-fat whipped topping to lighten the dessert slightly.
- Try swapping the chocolate cake mix for a yellow or spice cake mix for a different flavor profile.
- Make sure the butter is cold and sliced thinly to help it melt evenly.
Storage
Store any leftovers covered in the refrigerator for up to 3 days. Reheat gently in the microwave before serving to restore softness, but note the texture won’t be quite as tender as when freshly baked.

FAQs
Can I use regular cream instead of whipped topping?
Whipped topping adds both texture and sweetness to the cake, so using regular cream won’t give the same result. You can try whipped cream, but it may alter the consistency.
Is this dessert gluten-free?
This recipe is not gluten-free due to the Oreos and cake mix, which contain wheat. You could try gluten-free cake mix and Oreo alternatives if needed, but results may vary.

Oreo Dump Cake Recipe
- Total Time: 50 minutes
- Yield: 12 servings 1x
Description
This Oreo Dump Cake is a quick and easy dessert that layers Oreos, sweetened condensed milk, whipped topping, chocolate cake mix, and butter to create a rich, fudgy treat. Baked to perfection, it’s best served warm with a gooey texture and a crunchy Oreo topping.
Ingredients
Base Layer
- 24 Oreo cookies (divided use; about 18–22 for base plus 6 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
Instructions
- Preheat and prepare pan: Preheat oven to 350°F (175°C) and grease a 9×13-inch baking pan with non-stick spray to prevent sticking.
- Arrange Oreos: Place Oreos in a single layer on the bottom of the pan. Use approximately 18 to 22 cookies depending on pan size for even coverage.
- Add condensed milk and topping: Pour the sweetened condensed milk evenly over the Oreos. Then spread the thawed whipped topping smoothly over the condensed milk layer.
- Sprinkle cake mix: Sprinkle the dry chocolate fudge cake mix evenly over the whipped topping to ensure full coverage.
- Add butter slices: Evenly distribute cold, thinly sliced butter on top of the cake mix to help it melt down during baking, creating a moist texture.
- Top with chopped Oreos: Chop the remaining 6 Oreo cookies and sprinkle atop the butter slices for added crunch and flavor.
- Bake and serve: Bake in the oven for 35-40 minutes until edges are bubbly and cake mix looks set. Serve immediately while warm for best scooping and gooey texture, as cooling will make it firmer and harder to serve.
Notes
- Best served warm right after baking for soft, scoopable texture.
- Can vary slightly in Oreo count depending on pan size, just cover bottom layer fully.
- Use cold butter sliced thinly to ensure even melting and moisture distribution.
- Cool Whip or similar whipped topping should be fully thawed before spreading.
- Leftovers can be refrigerated but will harden; reheat gently to soften.
