To make Heavenly Oreo Dessert, follow these simple steps:

1. Prepare the Crust: In a medium bowl, mix the crushed Oreo cookies with melted butter until well combined.
2. Press into Pan: Firmly press the mixture into the bottom of a 9×13-inch baking dish to form the crust.
3. Make Cream Cheese Layer: In a mixing bowl, beat the softened cream cheese and powdered sugar together until smooth.
4. Add Whipped Topping: Gently fold in 1 cup of whipped topping into the cream cheese mixture until combined.
5. Spread Cream Cheese Layer: Spoon the cream cheese layer over the crust in the baking dish, spreading it evenly.
6. Prepare Pudding Layer: In another bowl, whisk together the instant vanilla pudding mix and cold milk for about 2 minutes until thickened.
7. Layer Pudding: Pour the pudding on top of the cream cheese layer and spread it evenly.
8. Add More Whipped Topping: Top the pudding layer with the remaining whipped topping.
9. Chill: Cover the dessert and refrigerate for at least 4 hours, or overnight for best results.
10. Garnish: Before serving, sprinkle additional crushed Oreos or chocolate chips over the top for decoration.

These steps will lead you to an incredibly satisfying dessert that captures the spirit of indulgence.
