Ingredients You’ll Need
Every ingredient in this Oreo Dump Cake Recipe plays a simple yet essential role, coming together to create a dreamy combination of flavors and textures. From the crisp Oreos to the velvety Cool Whip, each component adds its unique character, making the whole dessert unforgettable.
- Oreo cookies, 20: These provide the celebrated chocolatey crunch and rich cream center that define the dessert’s base.
- Sweetened condensed milk, 14 ounces: Acts as the luscious, gooey binder that adds irresistible sweetness and creaminess.
- Cool Whip, 8 ounces, thawed: Lightens the dessert with airy texture and a smooth, creamy layer between the cookies and cake mix.
- Chocolate cake mix, 1 box: Sprinkled on top to form a cakey crust full of intense cocoa flavor after baking.
- Butter, ¾ cup (cut into pats): Melts into the cake mix while baking, creating a golden, buttery topping that complements the rich chocolate perfectly.
How to Make Oreo Dump Cake Recipe
Step 1: Prep Your Pan and Oven
First things first, preheat your oven to 350°F (175°C). Preparing your baking dish properly is key, so lightly grease a 9×13 inch baking pan with butter or non-stick spray. This prevents sticking and helps your dump cake come out perfectly every time.
Step 2: Create the Oreo Base
Arrange two layers of Oreo cookies across the bottom of your prepared dish, using about 10 cookies per layer. This crunchy foundation is what makes the Oreo Dump Cake Recipe stand out, giving you that delicious signature texture in every bite.
Step 3: Add the Creamy Layers
Pour the entire 14-ounce can of sweetened condensed milk evenly over the Oreo cookies to coat them with that rich sweetness. Then, use a spatula to spread the thawed Cool Whip evenly on top of the condensed milk layer. This combination adds creamy moisture that balances the dense cookies and cake mix.
Step 4: Sprinkle the Chocolate Cake Mix
Generously sprinkle the whole box of chocolate cake mix evenly over the top layer of Cool Whip. Use a fork to gently rake through the cake mix to break apart any lumps so it distributes evenly when baking into a crispy, cakey topping.
Step 5: Add Butter and Bake
Slice your butter into pats about one tablespoon each and scatter them over the top of the chocolate cake mix, aiming to cover as much surface as possible. Do not stir or mix the butter in; it melts during baking to create those gorgeous, golden, crispy edges you’ll love.
Bake your Oreo Dump Cake Recipe in the preheated oven for about 40-45 minutes. When it’s done, the top will be bubbly and golden. Let it cool slightly before serving to let the layers set for easier slicing.
How to Serve Oreo Dump Cake Recipe

Garnishes
While this dessert shines on its own, adding a few simple garnishes can elevate the experience. Try sprinkling crushed Oreos on top or a drizzle of chocolate syrup to make it even more visually decadent. Fresh berries or a dollop of whipped cream also add a nice touch of freshness and color.
Side Dishes
Pair your Oreo Dump Cake Recipe with a scoop of vanilla ice cream or some rich chocolate mousse for a luxurious dessert spread. A cup of strong coffee or cold milk perfectly complements the dessert’s sweetness, balancing flavors in the best way possible.
Creative Ways to Present
For parties, consider serving this dessert in individual mason jars or parfait glasses layered with extra crushed Oreos or mini chocolate chips. Another fun idea is to turn it into a trifle by layering the dump cake with pudding and whipped topping for a show-stopping presentation.
Make Ahead and Storage
Storing Leftovers
Oreo Dump Cake Recipe leftovers stay moist and delicious when stored in an airtight container in the refrigerator. They will keep well for up to 4 days, making it a convenient treat to enjoy over several days or to prep ahead of time.
Freezing
You can freeze the cake after it has completely cooled. Wrap tightly in plastic wrap and then in aluminum foil or place in a freezer-safe container. Frozen Oreo Dump Cake can last up to 2 months. Thaw overnight in the refrigerator before reheating or serving.
Reheating
To enjoy warm, gently reheat individual slices in the microwave for 15-20 seconds or warm the whole dish at 300°F for about 15 minutes. This reawakens the gooey layers and melts the butter to bring back that fresh-baked charm.
FAQs
Can I use a different type of cookie instead of Oreos?
Absolutely! While Oreos provide that classic flavor, you can swap in other sandwich cookies or chocolate chip cookies for a different twist. Just make sure they hold up well during baking.
Is it necessary to thaw the Cool Whip before using?
Yes, thawing Cool Whip makes it easier to spread evenly over the condensed milk, creating smooth layers that bake perfectly in the Oreo Dump Cake Recipe.
Can I use homemade whipped cream instead of Cool Whip?
You can substitute homemade whipped cream, but keep in mind it may not hold up as well during baking. Cool Whip provides a stable texture and sweetness that’s ideal for this recipe.
What if I want this dessert gluten-free?
Use gluten-free Oreos or a gluten-free cookie alternative and pick a gluten-free chocolate cake mix. That way you keep all the taste without the gluten.
How do I know when the cake is done baking?
The top will be bubbly and have a golden brown color. The butter on top should be melted completely. You do not need to insert a toothpick since the layers are moist; the bubbling top is a perfect indicator.
