Heat oven to 350°F.
In bowl, break up cookie dough. Stir or knead in 1/2 cup all-purpose flour until well blended. Shape dough into 72 (1-inch) balls. Roll balls in sugar in shallow bowl. On ungreased cookie sheets, place balls 2 inches apart. Bake 10 to 14 minutes or until edges are golden brown.
After removing from oven, immediately top each cookie with 1 candy, pressing down firmly so cookie cracks around edge. Remove from cookie sheets to cooling racks. Cool completely before storing.
