Can I make Oreo Dump Cake ahead of time?

Yes, you can assemble the layers up to a day in advance, cover it, and refrigerate. When ready, bake it fresh for the best gooey texture. It’s perfect for parties or potlucks since it reheats beautifully.

Why is my Oreo Dump Cake dry?

If your Oreo Dump Cake turned out dry, it’s usually because there wasn’t enough butter or condensed milk. Make sure to evenly cover the top with butter slices so they melt down through the cake mix during baking.

Can I use different flavors of Oreos or cake mix?

Absolutely! Try Golden Oreos, Mint Oreos, or even a Red Velvet cake mix for fun variations. Each combination adds a unique twist while keeping the same easy, dump-style method.

How should I store leftover Oreo Dump Cake?

Store any leftovers in an airtight container in the fridge for up to 4 days. Reheat individual portions in the microwave for about 20–30 seconds to bring back that warm, gooey texture.

Instructions

Preheat oven to 350°F and lightly grease a 9×13-inch baking dish.

Spread crushed Oreo cookies evenly across the bottom of the dish.

Pour sweetened condensed milk evenly over the cookies.

Add a layer of whipped topping without mixing.

Sprinkle the dry chocolate cake mix evenly over the top.

Arrange thin slices of butter across the entire surface.

Bake for 35–45 minutes until the top is golden and the edges are bubbly.

Cool for 10 minutes, then serve warm with ice cream or whipped cream.

Notes

Don’t mix the layers before baking — the magic happens in the oven.

Use evenly spaced butter slices to ensure a moist, gooey texture.

Best served warm; leftovers can be reheated for a fresh-from-the-oven taste.
