Tips & Variations

For an extra indulgent treat, serve the cake with a scoop of vanilla ice cream or drizzle with chocolate syrup.
You can substitute Cool Whip with homemade whipped cream for a fresher taste.
Try using a mix of regular and double-stuffed Oreos for added creaminess.
If you prefer a less sweet dessert, reduce the amount of sweetened condensed milk slightly.

Storage

Store any leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave for 20 to 30 seconds if desired, or enjoy cold. This cake tends to soften after refrigeration but remains delicious.

¼ – ½ cup (57 – 113 g) butter, melted

Dry Ingredients

15.25 oz. chocolate fudge cake mix

Instructions

Prep: Preheat the oven to 350°F (177°C). Lightly grease an 11 x 7 inch or 9 x 13 inch baking dish with a tablespoon of butter to prevent sticking.
Layer Oreos: Evenly spread 18 to 22 chocolate Oreo cookies across the bottom of the greased baking pan, depending on the pan size you choose.

Spread Cool Whip: Evenly spread the thawed cool whip over the sweetened condensed milk and Oreo layer, making sure the surface is smooth and uniform.
Top with Cake Mix: Evenly sprinkle the entire chocolate fudge cake mix across the surface of the cool whip layer to form the dry topping.
Add Butter: Place the cold butter slices evenly on top of the cake mix to cover as much area as possible. Then drizzle the melted butter between the slices to saturate the cake mix for a moist finish.
Garnish: Sprinkle the remaining 4 to 6 crushed Oreo cookies evenly over the top for added texture and decorative appeal.
Bake: Place the baking dish in the preheated oven and bake for 35 to 40 minutes until the sweetened condensed milk bubbles around the edges and looks lightly caramelized.
Cool and Serve: Remove from the oven and allow the dump cake to cool for 5 minutes. Scoop portions into bowls and optionally top with extra cool whip or ice cream if desired.

Notes

Butter slices should be cold to distribute more evenly during baking.
You can adjust the number of Oreos depending on the pan size used.
This dessert is best served warm but can be refrigerated and reheated.
For added flavor, try mixing in chopped nuts or mini chocolate chips before baking.
Ensure cool whip is fully thawed to spread easily.
