Melt chocolate candy coating in a double boiler or in the microwave according to package directions. Using forks or a dipping tool, dip cookie balls into the candy coating to cover. Tap fork on the side of the pan to remove any excess coating, and return to the waxed paper-lined baking sheets. Chill until set. Store, chilled, in an airtight container for up to 1 week (though good luck making them last that long).
