01 - Crush chocolate sandwich cookies in a large zip-top bag using a rolling pin or pulse in a food processor until fine crumbs form. Set aside for assembly.
02 - Beat softened cream cheese and butter together in a medium bowl until smooth and creamy. Add powdered sugar and continue beating until fully incorporated and lump-free.
03 - Whisk together instant vanilla pudding mix, cold milk, and vanilla extract in a separate bowl for about 2 minutes until mixture begins to thicken. Gently fold in whipped topping until smooth and combined.
04 - Sprinkle half of the crushed cookie crumbs evenly across the bottom of a 9x13-inch casserole dish, pressing lightly to create an even foundation layer.
05 - Spread the entire cream cheese mixture evenly over the cookie crumb base using an offset spatula or the back of a spoon, creating a smooth, uniform layer.
06 - Pour and spread the vanilla pudding mixture over the cream cheese layer, ensuring even coverage to the edges of the dish.
07 - Sprinkle remaining cookie crumbs generously over the pudding layer to create the final 'dirt' effect, covering completely.
08 - Arrange pastel chocolate eggs, candy-coated chocolates, and gummy candies on top of the cookie crumbs to resemble Easter eggs hidden in dirt. Add fresh mint leaves sporadically for greenery effect.
09 - Refrigerate casserole for at least 2 hours to allow layers to set properly. Serve cold directly from the dish.
