Prepare the Crust – In a mixing bowl, combine the crushed Oreo cookies with melted butter. Press into the bottom of a 9x13-inch baking dish and bake at 375°F (190°C) for 8-10 minutes (or refrigerate for a no-bake option).
Cream Cheese Layer – Beat the cream cheese with powdered sugar until smooth. Fold in 8 ounces of whipped topping, then spread evenly over the cooled crust.
Mint Pudding Layer – Whisk the pudding mixes and cold milk until thickened. Stir in mint extract and green gel food coloring until you reach your desired shade. Fold in the remaining whipped topping, then spread over the cream cheese layer.
Chill – Cover and refrigerate for at least 4-6 hours (or overnight) to allow the layers to set.
Serve & Enjoy – Garnish with crushed Oreos, whipped topping, or green sprinkles. Slice and serve chilled!
