2. In a medium bowl, stir together the crushed sandwich cookies and melted butter with a fork. Press into the bottom and up the sides of a 9 or 9 1/2 inch pie plate.
3. Sprinkle the milk chocolate chips, coconut, white or peanut butter chips, and additional chopped sandwich cookies over the crust. Pour the sweetened condensed milk over the filling. (Note: if your sweetened condensed milk is too thick to pour, transfer to a microwave safe bowl and heat on high for 15 to 20 seconds).
4. Bake for 25 to 35 minutes, until the top seems set and not gooey. Cool completely before serving. Store covered at room temperature for up to four days.
