Crush 24 Oreos into fine crumbs and mix with 1/2 cup of melted butter. Press into the bottom of a 9x13 dish and refrigerate for 5 minutes.

In a bowl, beat 8 ounces of cream cheese, 1 cup of heavy cream, and 1/2 cup of powdered sugar until smooth. Fold in 8 ounces of Cool Whip and spread over chilled crust. Refrigerate for 10 minutes.

Whisk together 2 boxes of instant chocolate pudding with 4 cups of cold milk until thick. Spread on top of the cream cheese layer and chill for another 10 minutes.

Spread an additional layer of Cool Whip over the pudding layer and garnish with crushed Oreos and optional chocolate curls. Chill for at least 1 hour before serving.

Slice into squares and serve chilled, enjoying the layers of flavor.
