How to Make the Recipe
Let’s walk through the steps to create this delicious Oreo Dump Cake:

- In a 9×13-inch baking dish, crush the Oreo cookies and spread them evenly across the bottom of the dish.
- Pour the sweetened condensed milk evenly over the crushed Oreos.
- Dollop the whipped topping (Cool Whip) over the condensed milk layer and spread it out gently.
- Sprinkle the chocolate cake mix evenly on top of the whipped topping. Do not mix the layers; leave them as they are.
- Slice the butter into thin pieces and place the slices evenly on top of the cake mix.
- Bake in the preheated oven for 35-40 minutes, or until the top is golden brown and the cake mix has cooked through.
- Allow the dump cake to cool slightly before serving. Serve warm with extra whipped topping or a scoop of vanilla ice cream, if desired.
Pro Tips for Making the Recipe
Here are a few tips to ensure your Oreo Dump Cake turns out perfectly every time:
- For an extra crunchy Oreo layer, consider using a food processor to finely crush the cookies before spreading them in the baking dish.
- Don’t overmix the layers—this is a dump cake, after all! The magic happens when the ingredients meld together in the oven.
- If you’re not a fan of Cool Whip, you can substitute it with freshly whipped heavy cream sweetened with a bit of sugar.
- Want to mix things up? Try using different flavors of Oreos, like Mint or Peanut Butter, for a unique twist.
How to Serve
Serving your Oreo Dump Cake is as easy as making it! Here are a few ideas to elevate your dessert game:
- Serve warm straight from the oven, topped with a dollop of whipped cream or a scoop of vanilla ice cream.
- Drizzle with chocolate sauce or caramel for an extra-decadent treat.
- Let it cool completely and serve with a side of fresh berries for a sweet and tangy contrast.
Make Ahead and Storage
One of the best things about this dump cake is its versatility when it comes to making ahead and storing:
- You can prepare the layers and refrigerate the dish overnight, then bake it fresh when you’re ready to serve.
- Leftovers can be stored in an airtight container at room temperature for up to 3 days.
- For a frozen treat, let the cake cool completely, then cover it tightly with plastic wrap and freeze for up to 2 months. Thaw at room temperature when you’re ready to enjoy.
