Heat oven to 350°F. In large bowl, break up cookie dough. Stir or knead in 1/4 cup flour until well blended. Remove half the dough, and refrigerate remaining dough until needed.
Sprinkle 2 tablespoons flour onto work surface. With rolling pin, roll dough 1/4 inch thick. With 2-inch heart-shaped cookie cutter, cut out dough hearts. On ungreased cookie sheets, place hearts 2 inches apart. Repeat with remaining dough.
Bake 8 to 10 minutes or until edges are light golden brown. Cool 2 minutes; remove from cookie sheets to cooling racks. Cool completely, about 10 minutes.
In small bowl, mix frosting and food color until desired pink color. Spread frosting on cookies. Decorate with assorted candies to look like faces.
