HEAT oven to 350ºF. Spray 9-inch pie plate with no-stick cooking spray.
COMBINE graham cracker crumbs, sugar and melted shortening in medium bowl. Mix well with fork. Press firmly onto bottom and up sides of pie plate. Bake 5 minutes. Cool.
SPREAD half of softened ice cream evenly into cooled crust. Pour topping evenly over top. Return to freezer to set, about 10 minutes. Carefully spread remaining ice cream over topping, covering completely. Freeze until firm, at least 4 hours.
DROP marshmallow creme by spoonfuls over top of pie. Using moistened fingertips, spread in even layer, covering top of ice cream layer completely. Sprinkle marshmallows evenly over top, pressing slightly to stick. Cover. Freeze until firm, about 4 hours.
HEAT broiler. Cover pie crust edges with foil. Broil about 1 minute or just until marshmallows are lightly golden, watching closely to avoid burning. Serve immediately.
