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 cake bakes evenly and comes out perfectly gooey. While the oven heats up, lightly grease a 9×13-inch baking dish with butter or non-stick spray so that nothing sticks!
Step 2: Layer the Oreos
Next, take those delightful Oreo cookies and arrange 10 of them in a single layer across the bottom of your baking dish. This sets the foundation of flavor and adds that iconic cookie crunch right from the start.
Step 3: Add Condensed Milk and Cool Whip
Pour the sweetened condensed milk evenly over the layer of Oreos. Then, gently spread the Cool Whip over the condensed milk using a spatula. This layer brings creaminess into every bite!
Step 4: Add Remaining Ingredients
Now sprinkle the entire box of chocolate cake mix evenly over the Cool Whip layer. Don’t worry about mixing; simply use a fork to break up any lumps in the cake mix. This helps ensure even baking and delicious results.
Step 5: Top with Butter
Distribute those small pats of butter evenly over the surface of the cake mix. It might seem odd not to stir, but this step is key—it allows the butter to melt as it bakes, creating that rich, gooey top!
Step 6: Bake
Pop your masterpiece into the oven and bake for about 40–45 minutes until you see bubbly goodness bubbling away on top. Let it cool for just a few minutes before diving in—you’ll want to savor every warm bite!
