How to Make Oreo Dump Cake
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). This ensures that your Oreo Dump Cake bakes evenly and achieves that perfect gooey texture. While it heats up, lightly grease a 9×13-inch baking dish with butter or non-stick spray.
Step 2: Layer the Oreos
Next, arrange 10 Oreo cookies in a single layer across the bottom of your prepared baking dish. This creates a crunchy base that will soak up all the delicious flavors as it bakes.
Step 3: Add Condensed Milk and Cool Whip
Now it’s time for some creaminess! Evenly pour the sweetened condensed milk over the Oreos. Then gently spread the Cool Whip over the milk using a spatula. This adds layers of flavor and helps create that gooey texture we love.
Step 4: Add Remaining Ingredients
Sprinkle the entire box of chocolate cake mix evenly over the Cool Whip layer. Use a fork to break up any lumps in the cake mix; this step is important for even baking.
Step 5: Top with Butter
Distribute those little pats of butter evenly over the surface of the cake mix. Resist the urge to stir or mix; these pats will melt while baking and give us that deliciously rich topping.
Step 6: Bake
Pop your creation into the oven and bake for about 40–45 minutes or until the top is bubbly and slightly crisp. The aroma will fill your kitchen! Allow it to cool for a few minutes before serving warm—trust me, it’s worth the wait!
Pro Tips for Making Oreo Dump Cake
To ensure your Oreo Dump Cake turns out perfectly every time, here are some handy tips that will make the process a breeze!
-
Use room temperature ingredients: Letting your Cool Whip and condensed milk come to room temperature helps them blend more easily, creating a smoother texture in the finished cake.
-
Crush extra Oreos for added texture: If you want a little crunch, crumble some additional Oreos and sprinkle them on top before baking. This adds an extra layer of chocolatey goodness and a delightful texture.
-
Experiment with flavors: While this recipe is delicious as is, consider using different flavored cake mixes (like vanilla or red velvet) to create unique variations of the dump cake. It’s a fun way to personalize it!
-
Don’t skip cooling time: Allowing the cake to cool for a few minutes before serving ensures that it sets up nicely. This gives you gooey slices instead of a soupy mess—more enjoyable for you and your guests!
-
Serve warm for ultimate indulgence: This cake is best served warm, straight from the oven. The gooey layers combined with the cold Cool Whip create an irresistible contrast that everyone will love.
