Ingredients
Scale
- 25 Oreo cookies: The star of the show, Oreo cookies form the base of this delicious cake. The classic chocolate sandwich cookie provides a satisfying crunch and intense chocolate flavor. You can use regular Oreos or double-stuffed Oreos for an extra creamy filling.
- 14 ounces Sweetened Condensed Milk: This ingredient is essential for giving the cake its rich, creamy texture. As it bakes, the sweetened condensed milk soaks into the Oreos, creating a moist, fudgy base that’s both sweet and satisfying.
- 8 ounces Whipped Topping (Cool Whip): Cool Whip or any other non-frozen whipped topping adds a fluffy, light texture to the cake. It helps balance the richness of the other ingredients, contributing to the cake’s overall softness and creaminess.
- 15¼ ounces Chocolate Cake Mix: This chocolate cake mix is the key to giving the Oreo Dump Cake its soft, moist cake-like consistency. The cake mix is the foundation that holds all the other ingredients together and bakes into a golden, slightly crispy top layer.
- ½ cup Sweet Salted Butter, sliced: Butter is the finishing touch that makes this cake so indulgent. The butter melts over the dry cake mix, adding richness and flavor, and helping the cake crisp up on top while keeping the interior soft and gooey.
Instructions
- Preheat the Oven
Start by preheating your oven to 350°F (175°C). This is an essential first step in any baking process to ensure that your cake bakes evenly. A preheated oven allows the cake to rise properly and gives the top of the cake a beautiful, golden brown color while keeping the inside moist and gooey. - Prepare the Baking Pan
Grease a 9×13-inch baking pan with cooking spray. This ensures that the cake doesn’t stick to the pan, allowing you to serve it easily later on. If you don’t have cooking spray on hand, butter or even a light coat of vegetable oil will work as well. Make sure the entire bottom and sides of the pan are greased to prevent any sticking. - Arrange the Oreos
Next, arrange the 25 Oreo cookies in a single layer across the bottom of the greased baking pan. The Oreos form the base of the cake, and they will create a delicious crunchy texture once baked. Lay the cookies flat so they form a full layer across the bottom of the pan. If you prefer, you can break the Oreos into smaller pieces or even crush them slightly for a more uniform texture. - Pour the Sweetened Condensed Milk
Take your can of sweetened condensed milk and pour it evenly over the layer of Oreos. This ingredient is what makes the cake so decadently sweet and creamy. As the cake bakes, the condensed milk soaks into the Oreos, creating a moist, fudgy bottom layer that contrasts beautifully with the crisp, chocolatey cake on top. Be sure to spread the milk out evenly so that every Oreo gets some of that sweet, creamy goodness. - Spread the Whipped Topping
Now, spread the 8 ounces of whipped topping over the sweetened condensed milk layer. You want to cover the entire surface of the cake with a smooth, even layer of whipped topping. The whipped topping adds a light, airy texture to the cake and helps balance the richness of the other ingredients. As the cake bakes, the whipped topping becomes golden and slightly crispy around the edges, but it stays soft and creamy in the middle. - Sprinkle the Cake Mix
Take the dry chocolate cake mix and evenly sprinkle it over the whipped topping layer. This is the “dump” part of the dump cake! Don’t stir or mix the cake mix with the other ingredients. The dry cake mix will absorb the moisture as it bakes and transform into a beautiful, soft cake layer. Make sure the cake mix is spread out as evenly as possible, covering the entire surface. - Top with Sliced Butter
Arrange the sliced butter evenly over the top of the dry cake mix. The butter will melt into the cake as it bakes, helping to form a deliciously golden, crispy crust. The richness of the butter enhances the flavor of the chocolate cake mix, adding depth and a slight buttery flavor to the finished dessert. - Add Crushed Oreos
For an extra burst of flavor and texture, chop up 8 more Oreo cookies and sprinkle them over the top of the cake before baking. These crushed Oreos will add a bit of crunch to each bite and elevate the Oreo flavor, giving your cake a bit of extra indulgence. If you prefer more crunch, feel free to add more chopped Oreos to the top. - Bake the Cake
Place the baking pan in the preheated oven and bake for 35 to 40 minutes. During baking, the top of the cake will become golden brown and crispy, while the interior will remain gooey and soft. If you notice that the edges of the cake are getting too dark, you can cover the pan with aluminum foil for the last 10 minutes of baking. When the cake is done, a toothpick inserted into the center should come out clean or with just a few moist crumbs. - Serve and Enjoy
Once the cake is done baking, remove it from the oven and let it cool for about 5 minutes before serving. This allows the cake to set a little and makes it easier to serve. When you’re ready to serve, dish up a generous portion of warm cake topped with a scoop of vanilla ice cream and a drizzle of chocolate sauce. The combination of the warm, gooey cake with the cold ice cream is absolutely irresistible.
Notes
- Substitutions: If you’re looking for a lighter version of the cake, consider swapping the whipped topping for a low-fat version, or even Greek yogurt for a tangy contrast. You could also use a reduced-fat or sugar-free cake mix if you want to cut down on the sweetness.
- Add-Ins: Try adding some mini chocolate chips or chopped nuts, such as walnuts or pecans, to the cake mix layer for added texture and flavor. You can also mix in some peanut butter for a PB & Oreo version of this dessert.
- Serving Suggestions: This dessert is best served warm, straight from the oven. However, you can also make it ahead of time and store it in the fridge. Reheat individual servings in the microwave for a few seconds before serving. Pair it with a cup of coffee or a glass of milk for the perfect dessert experience. You could even drizzle some caramel sauce or raspberry sauce over the top for an extra burst of flavor.
