Ingredients You’ll Need

One of the many beautiful things about the Oreo Dump Cake Recipe is how it transforms a handful of pantry staples into a swoon-worthy dessert. Each ingredient here adds a special touch, whether it’s creaminess, crunch, or that craveable chocolate flavor.

Oreo cookies: The ultimate crunchy, chocolatey base that melts into pockets of deliciousness as it bakes.
Sweetened condensed milk: Adds rich, gooey sweetness and helps create those irresistible fudgy bites.
Cool Whip (thawed): Lends a creamy, pillowy layer that contrasts beautifully with the other textures.
Chocolate cake mix: Brings depth of chocolate flavor and the familiar, tender crumb of classic cakes.
Butter (cut into pats): Ensures a golden, melt-in-your-mouth finish across the cake’s top.

How to Make Oreo Dump Cake Recipe

Step 1: Prep the Pan and Oven

Start by preheating your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or non-stick spray. This little step ensures that all those lovely, gooey layers of your Oreo Dump Cake Recipe lift out cleanly every time.

Step 2: Layer the Oreos

Add two snug rows of 10 Oreo cookies directly into the bottom of your prepared pan. Don’t be shy about tucking them in corner-to-corner — these cookies are the base and will soak up all that delicious moisture from the layers above.

Step 3: Sweetened Condensed Milk Pour

Drizzle the entire can of sweetened condensed milk evenly over your Oreos. This step is pure magic: as the cake bakes, the milk seeps into the cookies and creates creamy, almost caramelized pockets no one will be able to resist.

Step 4: Layer on the Cool Whip

Next, gently spread the thawed Cool Whip over top of the condensed milk. Use a spatula to smooth it out into an even layer. This adds a luscious, slightly tangy creaminess right in the heart of the Oreo Dump Cake Recipe.

Step 5: Sprinkle the Chocolate Cake Mix

Evenly sprinkle the chocolate cake mix straight from the box across the Cool Whip layer. Use a fork to gently break up any clumps — you want a smooth, even coverage for a perfectly baked top layer.

Step 6: Top with Butter

Arrange the slices (or pats) of butter all over the surface of the dry cake mix. Space them across as much of the cake’s surface as possible so everything bakes up golden and moist. Resist the urge to mix — the magic truly happens as it bakes together!

Step 7: Bake and Serve

Slide the baking dish into your oven and bake for 40 to 45 minutes, or until the top is bubbly and cooked through. Allow your Oreo Dump Cake Recipe to cool for at least 10 minutes before serving. This is the perfect time for the layers to settle and for all those divine aromas to waft through your kitchen.

How to Serve Oreo Dump Cake Recipe

Garnishes

Add a flourish! Some of my favorite ways to finish this easy treat include a dollop of whipped cream, a drizzle of chocolate syrup, or an extra crumble of Oreo cookies right on top for even more crunch and nostalgia.

Side Dishes

Pair your Oreo Dump Cake Recipe with a scoop of classic vanilla ice cream, a tall cold glass of milk, or even a spoonful of fresh strawberries. It’s rich, so a little creamy or fruity side is a perfect match.

Creative Ways to Present

Scoop the warm cake straight into individual mason jars for a fun party dessert, or serve in small ramekins with a mini Oreo perched on top. For potlucks, just bring it in the baking dish and let everyone dig in family-style — it’s always a hit!

Make Ahead and Storage

Storing Leftovers

Leftovers (if you’re lucky enough to have any!) can be covered tightly and stored in the refrigerator for up to 4 days. The flavors actually meld and intensify, making for an even fudgier slice the next day.

Freezing

You can freeze portions of Oreo Dump Cake Recipe by wrapping in foil and placing in a zip-top bag. It keeps well for up to 2 months. Just thaw overnight in the fridge before enjoying, or reheat straight from frozen if you’re in a hurry.

Reheating

For the best texture, warm leftovers in a 300°F (150°C) oven for about 10-12 minutes, or until heated through. You can also microwave individual servings for about 30 seconds, but the oven method keeps the crumb perfectly tender.

FAQs

Can I use a homemade chocolate cake mix instead of a boxed one?

Absolutely! Your favorite homemade dry cake mix will work beautifully. Just make sure it’s about the same weight as a standard box for the best results.

What’s the best way to crush extra Oreos for topping?

Pop a handful of Oreos into a zip-top bag and give them a few smacks with a rolling pin or heavy spoon. You want bigger chunks for crunch but not fine crumbs.

Can I make this Oreo Dump Cake Recipe gluten-free?

Yes! Simply choose gluten-free chocolate sandwich cookies and a gluten-free chocolate cake mix. The rest of the ingredients are naturally gluten-free.

Is it possible to swap out Cool Whip for homemade whipped cream?

Homemade whipped cream works if you’re serving right away, but Cool Whip holds up better for storage and in the oven during baking.

How do I know the cake is fully baked?

The top should look set and slightly crisped, and the edges will bubble with gooey, chocolaty goodness. If you gently press the center with a spoon and it springs back, your Oreo Dump Cake Recipe is ready!

Final Thoughts

If you’re searching for your next go-to, crowd-pleasing dessert, look no further than this Oreo Dump Cake Recipe. Each bite delivers pure comfort and unmistakable nostalgia. I hope you have as much fun making and sharing it as I do — give it a try and watch every spoonful disappear!
