How to Make Oreo Dump Cake
Step 1: Preheat the Oven
Preheating your oven is key to ensuring your cake bakes evenly. Set it to 350°F (175°C) and lightly grease a 9×13-inch baking dish with butter or non-stick spray so that your dessert doesn’t stick.
Step 2: Layer the Oreos
Start by arranging 10 Oreo cookies in a single layer across the bottom of your greased baking dish. This will form a delicious base that adds texture and flavor to your cake.
Step 3: Add Condensed Milk and Cool Whip
Next, evenly pour the sweetened condensed milk over the Oreos. This step is crucial because it keeps the cookies moist while they bake. Gently spread the Cool Whip over the milk using a spatula—it adds creaminess that’s hard to resist!
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 ensures that every bite is soft and fluffy.
Step 5: Top with Butter
Distribute pats of unsalted butter over the surface of the cake mix without stirring. This helps create that irresistible crispy top while keeping everything underneath nice and gooey.
Step 6: Bake
Finally, pop your creation into the oven and bake for 40–45 minutes or until the top is bubbly and slightly crisp. Allow it to cool for just a few minutes before diving in warm—trust me, you won’t want to wait!
Pro Tips for Making Oreo Dump Cake
Making Oreo Dump Cake is a breeze, but a few handy tips can elevate your dessert to the next level!
-
Use fresh ingredients: Fresh cookies and whipped topping ensure that your cake has the best flavor and texture. Stale ingredients can lead to a less satisfying outcome.
-
Don’t skip the butter: Distributing pats of butter on top of the cake mix is essential for achieving that crispy, golden layer. It helps create a beautiful crust while keeping the inside gooey and moist.
-
Let it cool slightly before serving: Allowing the cake to cool for about 10 minutes will make it easier to serve and enhance its flavor. This cooling time lets the layers settle together beautifully.
-
Experiment with flavors: While Oreos are delicious, try using different flavored cookies or cake mixes for a fun twist. Mint Oreos or vanilla cake mix can add unique flavors that surprise your taste buds.
-
Store leftovers properly: If you have any leftovers (which might be unlikely!), store them in an airtight container in the fridge for up to 3 days. This keeps your dessert fresh and ready for another indulgent treat.
