Preheat oven to 325°.
In large bowl, with electric mixer, beat Country Crock® Spread, 1 cup confectioners sugar and brown sugar until light and fluffy, about 3 minutes. Gradually beat in flour and salt, scraping sides occasionally.
Shape dough into 1-inch balls and arrange on ungreased baking sheets, 2 inches apart. With flat bottom of glass dipped in cold water, flatten each cookie.
Bake 12 minutes or until lightly golden on edges. On wire rack, let stand 1 minute; remove from sheets and cool completely.
For glaze, blend remaining 1/2 cup confectioners sugar with water. Lightly spread over cooled cookies and garnish with decorative sprinkles.
