Ingredients You’ll Need
These ingredients are wonderfully straightforward but each plays a crucial role in bringing the Oreo Dump Cake Recipe to life. From the iconic Oreo cookies adding texture and flavor, to the creamy condensed milk and Cool Whip giving it a smooth, luscious consistency, every component is essential for creating that perfect balance of taste and texture.
- Oreo cookies: 20 cookies bring the classic chocolate and cream crunch that defines this dessert.
- Sweetened condensed milk: One 14-ounce can adds sweetness and a silky smooth binding layer.
- Cool Whip: An 8-ounce container, thawed, provides a creamy, light topping that balances richness.
- Chocolate cake mix: One box forms the cake layer, keeping things easy while adding deep chocolate flavor.
- Butter: ¾ cup, sliced into pats to melt on top, creating a golden, buttery crust as it bakes.
How to Make Oreo Dump Cake Recipe
Step 1: Prepare Your Baking Dish
Start by preheating your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or non-stick spray to ensure your cake will release easily once baked. This simple prep step avoids any stuck edges and makes cleanup a breeze.
Step 2: Layer the Oreos
Arrange two layers of 10 Oreo cookies each across the bottom of the prepared dish. This creates a crunchy, chocolatey base that will soften ever so slightly as it bakes, soaking up the condensed milk and Cool Whip flavors beautifully.
Step 3: Add Sweetened Condensed Milk and Cool Whip
Pour the entire 14-ounce can of sweetened condensed milk evenly over the Oreo layers. This gooey layer adds deep, creamy sweetness that ties everything together. Next, spread the thawed Cool Whip gently on top, creating a fluffy, creamy topping that contrasts perfectly with the denser layers below.
Step 4: Sprinkle the Cake Mix
Evenly sprinkle one box of chocolate cake mix over the Cool Whip layer. Use a fork to gently rake and break up any clumps so the cake mix is light and spread out evenly. This dry layer will absorb moisture during baking and create a soft, chocolaty crust.
Step 5: Add Butter and Bake
Cut the butter into small pats or slices and scatter them across the cake mix to cover as much surface as possible. These butter pats will melt into the cake as it bakes, producing a rich, golden crust. Bake in the preheated oven for 40 to 45 minutes, or until the top is bubbly and golden. Let the cake cool slightly before serving to allow everything to set perfectly.
How to Serve Oreo Dump Cake Recipe

Garnishes
Enhance your Oreo Dump Cake Recipe by adding fun garnishes like a dollop of whipped cream, a drizzle of chocolate or caramel sauce, or even a sprinkle of crushed Oreos on top. Fresh berries can provide a lovely pop of color and a hint of tartness that contrasts the rich sweetness.
Side Dishes
This dessert shines on its own but pairs beautifully with cold milk or a scoop of vanilla ice cream for those extra special indulgences. It can also be served alongside fresh fruit or a simple espresso to round out your dessert experience.
Creative Ways to Present
For a charming presentation, serve the Oreo Dump Cake Recipe in individual glass jars or clear bowls to showcase all the delicious layers. You can also cut it into squares and serve with a mint leaf or edible flower for a touch of elegance that’s sure to wow your guests.
Make Ahead and Storage
Storing Leftovers
If you have any leftovers, cover the Oreo Dump Cake tightly with plastic wrap or foil and store it in the refrigerator. It will keep well for about 3 to 4 days, allowing the flavors to meld even more deliciously.
Freezing
You can freeze the cake by wrapping it securely in plastic wrap and then aluminum foil to prevent freezer burn. For best texture, consume within 1 to 2 months. When ready to enjoy, thaw it overnight in the fridge.
Reheating
To warm up your leftover Oreo Dump Cake Recipe, simply microwave individual portions for 20 to 30 seconds or heat the whole dish at 300°F (150°C) for about 15 minutes until warmed through. Be careful not to overheat, as the whipped topping can melt away.
FAQs
Can I use a different flavor of cake mix?
Absolutely! While chocolate complements the Oreos perfectly, you could try vanilla or even red velvet for a fun twist. Just remember that the flavor of the cake mix will shine through, so pick one that pairs well with chocolate.
Is there a way to make this Oreo Dump Cake Recipe gluten-free?
Yes. You can substitute gluten-free chocolate cake mix and gluten-free Oreos, which are available in many stores. This way, the dessert remains safe for those with gluten sensitivities without sacrificing flavor.
Can I prepare this dessert ahead of time for a party?
Definitely! In fact, making the Oreo Dump Cake Recipe a few hours in advance allows the flavors to mingle. Just bake it shortly before serving or reheat slightly if you prefer it warm.
What’s the best way to crush the Oreos if I want a finer texture?
You can place the Oreos in a resealable plastic bag and gently crush them with a rolling pin or use a food processor for a finer crumb. This will change the texture but still taste delicious.
Is it necessary to use sweetened condensed milk?
Sweetened condensed milk is key to this recipe’s creamy sweetness and structure. Using a substitute might affect the texture and flavor significantly, so it’s best to stick with it for authentic results.
