Add 2 cups of the crushed Oreo cookies to a small (3-4 cups) mixing bowl. Pour the melted and cooled butter over the crushed cookies. Stir to completely coat the cookie crumbs.

Press the buttered Oreo crumbs into the bottom and up the sides of a standard 9 inch pie plate. (I used a sheet of waxed paper and a ½ cup measuring to press the crumbs. This way the buttered crumbs will only stick to the pie plate and not your hands or measuring cup) Place the crust in the refrigerator while you prepare the filling.

Add the softened cream cheese to a medium (2-3 quarts) mixing bowl. (It’s very important that the cream cheese is softened, to reduce any lumps) Use a handheld mixer on medium speed to mix the cream cheese until smooth, about 1 ½ - 2 minutes.

Add the sifted powdered sugar and continue mixing for another 2 minutes, or until the cream cheese and powdered sugar are smooth.

In a separate medium sized mixing bowl, add the cold milk. Sprinkle the pudding mix over the milk. Use a handheld mixer on low speed, or a handheld whisk to mix the milk and pudding until thickened.

Add in 1 cup of the crushed cookie crumbs to the pudding and stir until evenly distributed.

Use a silicone spatula to gently fold the thawed whipped topping into the pudding and cookie crumb mixture. (Folding the whipped topping into the pudding should help keep the filling from being too dense)

Next, gently fold the cream cheese and powdered sugar mixture in the pudding.

Evenly spread the pudding filling into the chilled Oreo pie crust. Use either a silicone spatula or an offset spatula to smooth the filling.

Evenly sprinkle the remaining 1 cup of crushed Oreo crumbs over the top of the pie. Cover and chill in the refrigerator for 4 hours. Just before serving, cut the pie into 8 slices. Arrange the gummy worms (2-3 per slice) on top of the cookie crumb dirt.
