01 - Crush chocolate sandwich cookies in a large zip-top bag using a rolling pin or pulse in a food processor until they resemble fine crumbs. Set aside for layering.
02 - Beat softened cream cheese and butter together in a medium bowl until smooth and creamy. Add powdered sugar and continue beating until fully combined and fluffy.
03 - Whisk instant pudding mix, cold milk, and vanilla extract together until slightly thickened, approximately 2 minutes. Gently fold in thawed whipped topping until smooth and incorporated.
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.
05 - Spread all of the cream cheese mixture evenly over the cookie crumb base, using a spatula to create a smooth, uniform layer.
06 - Pour and spread the pudding mixture over the cream cheese layer, ensuring even coverage to the edges of the dish.
07 - Sprinkle remaining cookie crumbs over the pudding layer to create a realistic 'dirt' appearance for the garden theme.
08 - Arrange pastel chocolate eggs, candy-coated chocolates, and gummy candies on top to resemble Easter eggs hidden in dirt. Garnish with fresh mint leaves to simulate green grass.
09 - Refrigerate the casserole for at least 2 hours to allow layers to set properly. Serve cold for best texture and flavor.
