Method
Step 1: Prepare the Baking Dish
Preheat your oven to 350°F. Lightly grease a 9x13-inch baking pan to prevent sticking and make cleanup easier later.
Step 2: Build the Oreo Layer
Spread crushed Oreo cookies across the bottom of the dish. Don’t worry about making them perfectly even—this dessert is supposed to be easy and messy.
Step 3: Add the Creamy Layer
Drizzle sweetened condensed milk all over the cookies. Then spoon whipped topping across the surface to create a creamy cookies-and-cream center.
Step 4: Sprinkle the Cake Mix
Pour the dry chocolate cake mix evenly over everything. Resist the urge to stir. Dump cakes work best when the layers stay separate.
Step 5: Finish with Butter
Slice butter into thin pieces and place them across the top. As the cake bakes, the butter melts into the dry mix and creates a rich chocolate topping.
Step 6: Bake Until Gooey
Bake for about 40–45 minutes or until the top looks set and slightly crisp around the edges. The center should stay soft and fudgy.
Let it cool for 10 minutes before serving. Trust me, molten chocolate lava temperatures are no joke.
