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.
03 - Whisk instant vanilla pudding mix, cold milk, and vanilla extract in a separate bowl until slightly thickened, about 2 minutes. Gently fold in thawed whipped topping until smooth.
04 - Sprinkle half the crushed cookie crumbs evenly across the bottom of a 9x13-inch casserole dish.
05 - Spread the entire cream cheese mixture evenly over the cookie crumb layer.
06 - Pour and spread the pudding mixture over the cream cheese layer, ensuring even coverage.
07 - Sprinkle remaining cookie crumbs over the pudding layer to create the finished dirt appearance.
08 - Arrange pastel chocolate eggs, candy-coated chocolates, and gummy candies on top to resemble hidden Easter eggs. Garnish with fresh mint leaves for grass effect. Refrigerate at least 2 hours before serving.
