How To Make It
Here is everything you’ll need to make this delicious dessert. You can find the full ingredients list along with instructions on the recipe card below.
Preheat the oven to 350 degrees.
- First, Lightly grease a 9x13 baking dish and arrange the Oreo cookies in an even layer across the bottom of the pan. Pour the sweetened condensed milk evenly over the Oreos. Spread the Cool Whip over the top in an even layer.

- Sprinkle the dry chocolate cake mix evenly over everything. Place thin pats of butter evenly across the top of the cake mix. Bake for 40–45 minutes or until the top looks set and slightly crisp around the edges. Let cool slightly before serving and enjoy!

Pro Tips
- Slice the butter very thin so it covers more of the cake mix while baking.
- If you notice dry cake mix spots halfway through baking, lightly mist them with cooking spray or add a few extra butter pats.
- Let the cake rest for about 10 minutes before serving so the layers can settle slightly.
- Serve warm with vanilla ice cream for the ultimate dessert situation.
- Don’t crush the Oreos unless you want more of a crumb-style texture. Whole cookies create better layers.
Variations
- Peanut Butter Oreo Dump Cake- Add a drizzle of melted peanut butter or peanut butter chips before baking.
- Cookies and Cream Version- Use white cake mix instead of chocolate cake mix for more cookies-and-cream flavor.
- Extra Chocolate- Add chocolate chips between the Cool Whip and cake mix layers.
- Mint Oreo Dump Cake- Use Mint Oreos for a cool mint chocolate version.
Can This Be Made Ahead If Time?
Yes. You can assemble it a few hours ahead and bake when ready.
What Should I Serve This With?
This cake goes great topped with some vanilla ice cream, extra crushed Oreos, hot fudge or whipped cream.
Storage & Reheating
Store leftovers covered in the refrigerator for up to 4 days.
To reheat, microwave individual portions for about 20–30 seconds until warm and gooey again. You can also reheat larger portions in a 300 degree oven for about 10–15 minutes.
