Use 1 cooled graham cracker crust, 1 quart softened vanilla ice cream and 6 to 10 crushed Butterfingers (refrigerate and crush by hitting against counter) and Cool Whip or whip cream. (Don't use frozen.) Combine ice cream and most of the candy. Reserve some to garnish. Put in crust and freeze. When frozen, cover with Cool Whip and sprinkle with remaining candy. Re-freeze.
