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.
02 - Beat softened cream cheese and butter in a medium bowl until smooth and creamy. Add powdered sugar and beat until fully combined and fluffy.
03 - Whisk instant pudding mix with cold milk and vanilla extract in a separate bowl until slightly thickened, about 2 minutes. Gently fold in thawed whipped topping until smooth and incorporated.
04 - Sprinkle half the crushed cookie crumbs evenly across the bottom of a 9x13-inch casserole dish, pressing lightly to create an even base layer.
05 - Spread the entire cream cheese mixture evenly over the cookie crumb base, using a spatula to create a smooth, uniform layer.
06 - Pour and spread the vanilla pudding mixture over the cream cheese layer, ensuring complete coverage with an even surface.
07 - Sprinkle remaining cookie crumbs over the pudding layer to create the 'dirt' effect, covering completely.
08 - Arrange pastel chocolate eggs, candy-coated chocolates, and gummy candies on top to resemble Easter eggs hidden in dirt. Add fresh mint leaves as greenery accents.
09 - Refrigerate for at least 2 hours to allow layers to set completely. Serve cold and enjoy.
