In large bowl, break up cookie dough. Stir or knead in flour until well blended. Reshape into log. If too soft to cut into slices, refrigerate up to 30 minutes. Heat oven to 350°F. Cut dough into 16 (1/2-inch) slices. On ungreased cookie sheet, place slices 2 inches apart. Bake 12 to 14 minutes or until edges are light golden brown. Cool 2 minutes; remove from cookie sheet to cooling rack.
