If you like, in heavy saucepan, combine chocolate pieces and shortening; melt over medium-low heat. Dip part of cooled cookies into chocolate. Sprinkle with candies.
Cool cookies completely. The cookies keep in an airtight container at room temperature for up to 3 days. In a freezer container, arrange cookies in a single layer; cover with a sheet of waxed paper. Repeat layers, leaving enough air space to close container easily. Freeze up to 1 month.
