In small microwavable bowl, microwave candy melts uncovered on High 1 to 2 minutes, stirring every 30 seconds, until melted and stirred smooth. Dip each cookie halfway into melted candy, letting excess drip off. Place on waxed paper until almost set. Sprinkle dipped half of each cookie with edible glitter. Let cookies stand until candy coating is completely set, about 1 hour. Store between sheets of waxed paper in tightly covered container.
