Gather the fam for a viewing of your favorite Halloween movie and indulge in a ghostly treat of your own. With a 2 inch cookie cutter, cut a ghost shape out of your cookie. Place the empty cookie cutter on a plate. Blend yogurt, pumpkin and spice and spoon the mixture into the ghost and freeze for 30 minutes. Place the yogurt ghost on a plate and top with the cookie and go crazy with chocolate syrup and nuts. Spooky sound effects optional.
