Using a sharp knife, divide cookie dough roll into 8 portions. Working with one cookie dough portion at a time, roll into a 12-inch rope; cut crosswise into 24 (1/2-inch) pieces and shape into balls. Place cookie dough balls on a rimmed cookie sheet lined with waxed paper or parchment paper. Repeat rolling, cutting and shaping with remaining cookie dough. Refrigerate 30 minutes.
