Freeze 30 minutes or until slightly slushy. Stir 1 teaspoon chocolate chips into each cup. Insert wooden craft sticks in center. Freeze and an additional 1 1/2 to 2 hours or until completely firm. To serve, peel paper cup away form pop, or dip outsides of molds in warm water to loosen. For longer storage, place frozen pops in a large resealable freezer bag. Freeze up to 2 weeks. Makes 8 pops.
