How to Make Oreo Dump Cake
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). This step is crucial because it ensures your cake bakes evenly. While that’s heating up, lightly grease a 9×13-inch baking dish with butter or non-stick spray.
Step 2: Layer the Oreos
Now it’s time to layer those lovely Oreos! Arrange 10 cookies in a single layer across the bottom of your greased baking dish. This will form a delicious base for all those creamy layers above.
Step 3: Add Condensed Milk and Cool Whip
Next, evenly pour the sweetened condensed milk over the Oreos. This adds sweetness and moisture. Then gently spread the thawed Cool Whip over the milk using a spatula—it creates that fluffy layer we all love!
Step 4: Add Remaining Ingredients
Sprinkle the entire box of chocolate cake mix evenly over the Cool Whip layer. Don’t worry if there are lumps; use a fork to break them up gently for even baking later on.
Step 5: Top with Butter
Now for an extra touch of richness! Distribute those small pats of butter evenly over the surface of the cake mix. Resist the urge to stir; we want all those layers intact for maximum gooeyness!
Step 6: Bake
It’s time to bake! Place your creation in the oven and let it bake for about 40–45 minutes or until the top is bubbly and slightly crisp. Once done, allow it to cool for just a few minutes before serving warm—everyone will be eager to dig in!
Enjoy making this delightful Oreo Dump Cake! I can’t wait for you to share how much everyone loves it!
Pro Tips for Making Oreo Dump Cake
Creating the perfect Oreo Dump Cake is a breeze, especially with these handy tips to ensure your dessert turns out delicious every time!
-
Use fresh ingredients: Fresh cookies and a new can of sweetened condensed milk can significantly enhance the flavor. Stale ingredients may not provide the same delightful taste and texture.

Don’t skip the butter: Distributing pats of butter on top of the cake mix is essential. This helps create that gooey, crispy top layer that makes this dump cake so irresistible.
-
Let it cool slightly before serving: Allowing the cake to cool for about 10 minutes after baking helps it set a bit. This way, you’ll get nice, clean slices when serving!
-
