How to Make Oreo Dump Cake
Step 1: Preheat the Oven
First things first—set your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with butter or non-stick spray. Preheating ensures that your cake bakes evenly and gets that lovely golden top.
Step 2: Layer the Oreos
Next, arrange 10 Oreo cookies in a single layer across the bottom of the greased dish. This forms the base layer of your cake, adding that iconic cookie crunch we all love.
Step 3: Add Condensed Milk and Cool Whip
Evenly pour the sweetened condensed milk over the Oreos, letting it soak in all those flavors. Then gently spread the Cool Whip over the milk using a spatula. This creamy layer adds richness and balances out the sweetness.
Step 4: Add Remaining Ingredients
Now it’s time to 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 helps it bake more evenly and avoids any raw spots later.
Step 5: Top with Butter
Distribute those little pats of butter evenly over the surface of the cake mix. It’s important not to stir or mix at this stage; you’ll want those buttery bits to melt into luscious pockets while baking.
Step 6: Bake
Finally, pop your creation into the oven! Bake for about 40–45 minutes until the top is bubbly and slightly crisp. Once done, allow it to cool for a few minutes before serving warm—trust me, that’s when it’s at its best!
Enjoy making this scrumptious Oreo Dump Cake! It’s bound to become one of your favorite desserts too!
Pro Tips for Making Oreo Dump Cake
Making the perfect Oreo Dump Cake is a breeze, but these little tips will take it to the next level!
- Use fresh ingredients: Ensure your Cool Whip and sweetened condensed milk are fresh for the best flavor and texture. This way, you enhance the overall taste of your dessert.
- Crush some Oreos: For added texture, consider crushing a few extra Oreos and sprinkling them on top before baking. This adds a delightful crunch that contrasts beautifully with the gooey layers.
- Don’t skip the cooling time: Allowing the cake to cool for a few minutes before serving helps set up the layers and makes it easier to scoop without falling apart. Plus, it’s warm but not scalding hot!
- Experiment with toppings: Feel free to add chocolate syrup or whipped cream on top before serving. These extras can really enhance the visual appeal and flavor profile of your dessert.
- Store leftovers properly: If you have any leftovers (which is rare!), store them in an airtight container in the fridge. It keeps well for several days and makes for a quick treat whenever you need a sweet fix.
