Ingredients

Scale

Dry Ingredients

  • 1 box of chocolate cake mix
  • 20 Oreo cookies

Wet Ingredients

  • 14 ounces sweetened condensed milk (1 14-ounce can)
  • 1 8-ounce container Cool Whip, thawed for about 15 minutes before starting
  • 3/4 cup butter (1 1/2 sticks or 12 tablespoons), cut into 12 pats or more

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) to prepare for baking the cake.
  2. Prepare Oreos: Roughly crush the 20 Oreo cookies into smaller pieces, either by hand or using a food processor, to evenly distribute in the cake.
  3. Layer Ingredients: In a 9×13-inch baking dish, spread the crushed Oreos evenly over the bottom. Next, sprinkle the entire box of chocolate cake mix evenly over the Oreos.
  4. Add Sweetened Condensed Milk: Pour the 14 ounces of sweetened condensed milk evenly over the dry cake mix layer, ensuring thorough coverage to moisten the cake mix.
  5. Top with Butter: Place pats of the 3/4 cup butter evenly distributed across the entire surface of the cake mix to ensure even melting and a buttery crust.
  6. Bake the Cake: Bake in the preheated oven for about 45-50 minutes until the edges are bubbly and the cake is set.
  7. Cool and Serve: Remove from the oven and allow the cake to cool for at least 20 minutes. Once cooled, spread the thawed Cool Whip evenly over the top as a creamy topping before serving.

Notes

  • Thaw Cool Whip before spreading to ensure easy and smooth application.
  • You can crush Oreos to your preferred size—from coarse chunks to finer crumbs—for varied texture.
  • Use a glass or metal baking dish approximately 9×13 inches for best results.
  • Letting the cake cool before adding Cool Whip prevents it from melting and keeps the topping stable.
  • This cake is best stored refrigerated and served within 3-4 days.
