Ingredients

Scale

Base Layer

  • 20 Oreo cookies
  • 14 ounces sweetened condensed milk (1 14-ounce can)
  • 1 8-ounce container Cool Whip, thawed for about 15 minutes

Top Layer

  • 1 box chocolate cake mix (typically 15.25 ounces)
  • ¾ cup butter (1 ½ sticks or 12 tablespoons), cut into 12 pats or smaller slices

Instructions

  1. Preheat Oven: Preheat your oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish with butter or non-stick cooking spray to ensure the cake won’t stick.
  2. Layer Oreos: Arrange two layers of 10 Oreo cookies each evenly across the bottom of the prepared baking dish to form a solid base.
  3. Add Condensed Milk: Pour the 14 ounces of sweetened condensed milk evenly over the Oreo layers, allowing it to soak through and add rich sweetness.
  4. Spread Cool Whip: Use a spatula to evenly spread the thawed 8-ounce container of Cool Whip over the sweetened condensed milk, creating a smooth creamy layer.
  5. Sprinkle Cake Mix: Evenly sprinkle the entire box of chocolate cake mix on top of the Cool Whip layer. Use a fork to gently rake and break up any lumps for even coverage.
  6. Add Butter: Cut ¾ cup of butter into 1-tablespoon slices or smaller, and evenly distribute them across the surface of the cake mix. Do not stir or mix; just lay them on top.
  7. Bake: Place the baking dish in the preheated oven and bake for 40-45 minutes, until the top is golden and the butter has melted through the cake mix.
  8. Cool and Serve: Remove the cake from the oven and allow it to cool slightly before serving to let the layers set and flavors meld.

Notes

  • Make sure the Cool Whip is properly thawed for easier spreading.
  • Do not mix the cake batter once the butter is added on top; the butter melts and creates a crust during baking.
  • You can customize by adding chopped nuts or chocolate chips on top before baking for extra texture.
  • Allow the cake to cool for at least 10-15 minutes for best slicing and serving results.
