preheat the oven to 350˚

mix the cookie crumbs with the melted butter and press firmly into a pie pan

bake for 10 minutes, remove from the oven and cool completely

while the crust is cooling open the peanut butter cups, break them slightly and set aside

when the crust is cooled pour the the pudding mix, the whipping cream and the milk into a bowl

whip on high until well combined, about 3-4 minutes

for the last minute of whipping add about 2/3 of the peanut butter crumbles

scoop the whipped pie filling into the cooled crust and top with the last of the crumbled peanut butter cups

chill at least 2 hours, if leaving it longer consider covering it with some plastic wrap to keep errant things from being knocked into it
