Meet the Oreo Dump Cake: your new go-to dessert for those moments when you crave something decadent, effortless, and guaranteed to wow a crowd. This ridiculously simple cake layers classic Oreos, swirls of creamy condensed milk, a snowy cloud of Cool Whip, and rich chocolate cake in a single pan, all crowned with buttery goodness. The result? A melty, gooey, chocolate-lover’s dream—crunchy, creamy, and utterly irresistible in every bite!

Ingredients You’ll Need

This delicious recipe proves that magic happens when humble pantry staples come together. Each ingredient in this Oreo Dump Cake has a crucial part to play, whether it’s providing fudgy depth, creaminess, or that signature cookies-and-cream flair. Let’s peek inside your shopping bag:

Oreos: The heart and soul of this cake! Their crunchy chocolate wafers and creamy centers create the ultimate texture and flavor at the base.
Sweetened Condensed Milk (14 oz): Adds luscious, caramel-like richness and ensures every bite is moist and gooey.
Cool Whip (8 oz): This whipped topping lightens the middle layer, giving the cake a creamy lift and subtle sweetness.
Chocolate Cake Mix: A shortcut to dreamy chocolate flavor—delicate crumbs that bake into the fudgiest layer atop the cake.
Butter (1.5 sticks, cut into 1 Tbsp pieces): The rich, golden finish that melts into the cake mix, transforming it into a crisp, buttery topping.

How to Make Oreo Dump Cake

Step 1: Prep Your Pan

Start by heating your oven to 350 degrees F. Grab your trusty 9×13 pan and give it a generous mist of non-stick cooking spray—this makes serving your Oreo Dump Cake a total breeze (and keeps all those delicious, gooey bits from refusing to leave the pan!).

Step 2: The Oreo Layer

Place your Oreos in an even layer across the bottom of the prepared pan. Some folks like to break up a few cookies for extra fun texture—either way, make sure the pan is well covered with chocolatey goodness.

Step 3: Sweetened Condensed Milk Goodness

Pour the entire can of sweetened condensed milk evenly over the Oreos. This will start to soak into those cookies and provide a rich, fudgy base nobody can resist.

Step 4: Spread the Cool Whip

Drop dollops of Cool Whip across the condensed milk layer, then gently spread it out with a spatula or the back of a spoon. It’s okay if some areas are thicker than others—this adds to the creamy, melting magic of the finished Oreo Dump Cake.

Step 5: Chocolate Cake Mix Shower

Without mixing, sprinkle the entire package of chocolate cake mix evenly over the top. It should look powdery and cover the Cool Whip layer entirely. Resist the urge to stir—each layer bakes up best when left as is.

Step 6: Butter Makes It Better

Take those pieces of butter and dot them all over the surface of the cake mix. Try to cover as much of the top as possible with butter—this helps create that gorgeous, crispy, golden-brown crown as it bakes.

Step 7: Bake to Perfection

Slide your pan into the oven and bake for 40 to 45 minutes. Your Oreo Dump Cake is ready when the top is set, the edges are bubbling, and your kitchen smells impossibly chocolatey. Let it cool slightly before serving so those gooey layers set just a bit.

How to Serve Oreo Dump Cake

Garnishes

For that finishing touch, I love to crown slices with a scoop of vanilla ice cream and a crumble of extra Oreos. Sprinkle on chocolate chips, a drizzle of chocolate syrup, or even a few fresh berries for a pop of color and tangy contrast.

Side Dishes

If you’re serving Oreo Dump Cake at a gathering, pair it with fresh strawberries or sliced bananas to balance the richness. A big mug of coffee or a glass of cold milk is the perfect companion for this ultra-indulgent treat.

Creative Ways to Present

Try building mini Oreo Dump Cake trifles in jars for individual servings, or bake in ramekins for personal-sized portions. Want to take it over the top? Add a dollop of espresso whipped cream or some chopped toasted nuts for a grown-up spin.

Make Ahead and Storage

Storing Leftovers

Got leftovers (lucky you)? Simply cover the pan tightly with foil or transfer slices to an airtight container. They’ll keep well in the refrigerator for 3 to 4 days—if they last that long!

Freezing

To freeze, let your Oreo Dump Cake cool completely, then wrap individual slices (or the entire pan) tightly in plastic wrap and foil. It’ll stay fresh for up to 3 months. Thaw overnight in the fridge when those chocolate cravings strike.

Reheating

For that fresh-from-the-oven magic, pop a slice in the microwave for about 20 to 30 seconds. Or, warm in a 300-degree oven (covered) for 10 to 15 minutes. Top with ice cream for that perfect hot-cold contrast.

FAQs

Can I use a different flavor of cake mix?

Absolutely! While chocolate makes this decadent and rich, feel free to experiment—try red velvet, devil’s food, or even vanilla for a fun twist on the classic Oreo Dump Cake.

Do I have to use Cool Whip, or can I substitute something else?

If Cool Whip isn’t your style, you can use any whipped topping, or even lightly sweetened homemade whipped cream. Just be sure it’s stabilized if you’re making ahead.

Can I make Oreo Dump Cake gluten free?

You sure can! Use a gluten-free chocolate cake mix and seek out gluten-free chocolate sandwich cookies. The rest of the ingredients are already gluten free, so everyone can join the party.

What’s the best way to cut and serve this cake?

Let the Oreo Dump Cake cool for 10 to 15 minutes after baking to help the layers set. Use a sharp knife and a wide spatula for clean servings—it can be a bit gooey (in the best way)!

How do I know when Oreo Dump Cake is finished baking?

The top should look set and slightly crisp, with the edges bubbling a bit. If you gently shake the pan and the center is still very jiggly, let it bake a few more minutes. It’s meant to be gooey but not soupy.

Final Thoughts

If you’re in the mood for an easy, crowd-pleasing dessert that brings maximum chocolate joy and barely any effort, Oreo Dump Cake is calling your name! Give it a try, share it with friends and family, and watch every last crumb disappear—you might just find your new signature treat.
