In a medium bowl, combine Oreo crumbs and melted butter; press mixture down evenly into the bottom of a spring form pan; chill in refrigerator for thirty minutes
A few minutes before crust is ready to fill, take ice cream out of freezer to soften slightly
Carefully spread half of ice cream over crust; top with chopped peanut butter cups
Cover pan with foil and freeze; make stabilized whipped cream
Spread whipped cream over peanut butter cup layer and place pie back in freezer for at least one hour or until ready to serve
