Ingredients
Cookies
- 20 – 28 Oreo cookies, divided
Wet Ingredients
- 14 oz. sweetened condensed milk
- 8 oz. cool whip, thawed
- ¼ – ½ cup (57 – 113 g) melted butter
Dry Ingredients
- 15.25 oz. chocolate fudge cake mix
Butter
- ½ cup (113 g) cold butter, evenly sliced
Instructions
- Prep: Preheat the oven to 350°F (177°C). Lightly grease an 11 x 7 or 9 x 13 inch baking dish using a tablespoon of butter to prevent sticking.
- Layer Oreos: Evenly spread 18 to 22 whole chocolate Oreo cookies across the bottom of the prepared baking pan.
- Add Sweetened Condensed Milk: Pour 14 oz. of sweetened condensed milk evenly over the Oreo layer, ensuring coverage to allow caramelization during baking.
- Spread Cool Whip: Evenly spread 8 oz. of thawed cool whip on top of the sweetened condensed milk and cookie mixture to create a creamy layer.
- Add Cake Mix: Sprinkle 15.25 oz. of dry chocolate fudge cake mix evenly over the cool whip layer for texture and chocolate flavor.
- Add Butter: Place cold butter slices (½ cup, 113 g) evenly over the dry cake mix to help moisten and enrich the cake while baking. Then drizzle ¼ to ½ cup (57 – 113 g) of melted butter evenly over the butter slices and cake mix.
- Top with Crushed Oreos: Sprinkle 4 to 6 crushed Oreo cookies over the top for added texture and decorative finish.
- Bake: Place the baking dish in the preheated oven and bake for 35 to 40 minutes until the sweetened condensed milk bubbles and caramelizes around the edges.
- Cool and Serve: Remove from the oven and let cool for 5 minutes before scooping into bowls. Optionally, serve with ice cream for an extra indulgent treat.
Notes
- You can use either an 11 x 7 or 9 x 13 inch baking dish depending on the number of Oreos you use.
- Ensure butter slices cover as much of the cake mix as possible for even moistness.
- For best results, use chilled butter and melted butter as called for in the recipe.
- Serve warm with ice cream or whipped cream for added richness.
- Store leftovers covered in the refrigerator for up to 3 days.
