PREPARATION:

1. Preheat oven to 350°F. Lightly grease 10 mini (1-3/4-inch) muffin pan cups and 10 standard (2-1/2-inch) muffin pan cups. Shape one-third of dough into 10 (1-inch) balls; press onto bottoms and up sides of prepared mini muffin cups. Shape remaining two-third of dough into 10 equal balls; press onto bottoms and up sides of prepared standard muffin cups.
2. Bake mini cookies 8 to 9 minutes or until edges are light brown. Bake regular cookies 10 to 11 minutes or until edges are light brown. Cool 5 minutes in pans on wire racks. Remove cookies to wire racks; cool completely.
3. Add food coloring, if desired, to frosting; mix well. Spread frosting over top and side of each cookie. Place 1 mini cookie on top of 1 regular cookie. Decorate with sprinkles. Press 1 candle into center of each cookie.
