Heat oven to 350°F. Line large cookie sheets with cooking parchment paper. In medium bowl, break up cookie dough. Stir or knead in flour and 1/3 cup of the crushed candies, until well mixed. Shape dough into 36 (1-inch) balls; place 2 inches apart on cookie sheets. Bake 8 to 10 minutes or until edges are light golden brown. Cool 2 minutes; remove to cooling rack. Cool completely, about 30 minutes.
