In a bowl, combine cookie crumbs and butter. Set aside 1/2 cup for topping. Press remaining crumb mixture into a greased 13-in. x 9-in. x 2-in. dish. Freeze for 30 minutes. Spread ice cream over crust. Cover and freeze for 2-1/2 hours.
Sprinkle peanuts over ice cream. Cover and freeze for 1 hour. Spread with whipped topping (pan will be very full). Sprinkle with reserved crumb mixture. Freeze for 8 hours or overnight. May be frozen for up to 2 months. Remove from the freezer 15 minutes before serving. Cut into squares. Serve with hot fudge topping. Yield: 12-15 servings.
