After more than 14 years of baking desserts for family gatherings and special occasions, I’ve learned that a few simple ingredients can create a memorable treat. For this dump cake, spreading the butter pieces evenly across the dry cake mix helps the topping bake up more consistently, with a rich, fudgy texture throughout.

Ingredients
- Sweetened condensed milk. One 14-ounce can. It caramelizes around the Oreos as it bakes.
- Oreos. About 28 cookies, enough to cover the bottom of the pan in a single layer. Regular, Double Stuf, or Golden all work.
- Cool Whip. One 8-ounce tub, thawed. Frozen Cool Whip tears when you try to spread it over the condensed milk.
- Chocolate cake mix. One box. Chocolate fudge or devil’s food both work great. Just the dry mix, nothing else added.
- Butter. 1½ sticks, sliced as thin as you can. Thin pats cover more of the cake mix, which is what keeps the top from baking up dry and powdery. I use unsalted butter.

How To Make Oreo Dump Cake
Step 1. Preheat the oven to 350°F and spray a 9×13 pan with cooking spray.
Step 2. Place the Oreo cookies in the bottom of the baking dish in a single layer.
Step 3. Next, pour the sweetened condensed milk over the top of the Oreo cookies.
Step 4. Spread the cool whip on top using a spatula.
Step 5. Sprinkle the dry cake mix evenly over the Cool Whip, all the way to the edges. Break up any clumps with a fork, but don’t stir it into the layers below.
Step 6. Cover as much of the cake mix as you can with butter pats. If you see dry powdery spots, drizzle a little melted butter over them so the top doesn’t bake up floury.
Step 7. Bake for 40–45 minutes, until the top looks set and crisp and the condensed milk is bubbling and lightly caramelized around the edges. Let it cool 10 minutes, then scoop and serve warm.
Easy Flavor Combos
- Golden Oreo + yellow cake mix — a vanilla version kids love.
- Mint Oreos + chocolate cake mix — a mint chocolate version for Christmas.
- Peanut Butter Oreos + chocolate cake mix — like a peanut butter cup in cake form.
- Classic Oreos + red velvet cake mix — great for Valentine’s Day.
Storage
Scoop leftovers into an airtight container and refrigerate for up to 4 days. (If you leave it in the pan, the caramel layer can stick once it’s cold.) Reheat servings in the microwave for 20–30 seconds so the Oreos soften and it’s gooey again.
Serving ideas
- Add vanilla ice cream. Serve each slice warm with a scoop of vanilla ice cream and extra crushed Oreos. I love how the cool, creamy ice cream balances the rich chocolate.
- Try different ice cream flavors. Cookies and cream or chocolate ice cream makes this dessert even more decadent.
- Add extra Oreo crumbs. Place the cookies in a zip-top bag and crush them with a rolling pin. Sprinkle the crumbs over each serving for extra cookies and cream flavor.
Frequently Asked Questions
Leaving dry cake mix uncovered. Any spot that doesn’t get butter bakes up powdery instead of crisp. Slice the butter thin, cover as much of the top as you can, and drizzle melted butter over any bare spots before and during baking. (And don’t stir the layers. Each one needs to stay separate.)
It’s a scoopable dessert, so serve it with a big spoon instead of slicing.
It’s called a dump cake because the ingredients are dumped right into the baking dish. No mixing required.
Yes. Bake it up to a day ahead, cool, then scoop it into an airtight container and refrigerate. Warm individual servings in the microwave for 20–30 seconds so it’s gooey again.
Yes, break them into large chunks instead of crushing them finely. It still turns out great and is easier for small kids to eat.

Hi! I’m going to make this cake! I don’t need it til tomorrow
Is it ok to bake cool, then refrigerate?
Thank you, Connie
Ps I’ll let you know how people like it
Yes, I think that would work great!
Hi Carrie, this looks delicious! Is the butter supposed to be salted or unsalted?
Normally I bake with unsalted butter.
Should the cool whip be frozen or thawed?
Thawed. Thank you for commenting
Can this be made in a crockpot? If so, what temperature and how long?
Jennifer – I haven’t tested it yet but if you want to try, I would melt the butter and mix it with the cake mix before spreading it on top of the other ingredients. Then cook on high for 1 1/2- 2 hours until cooked through. If you try it out, please let me know how it turns out!
Would it change anything if I crumble the cookies up to make them more child and bite friendly?
Yes, you can definitely crumble the Oreos to make it easier for the kids to eat! I would just use larger chunks rather than crushing them too finely. It should still turn out delicious!
Thank you
