Team Spirit Frosted Brownies

Heat oven to 350°F. Line 9-inch square pan with foil, allowing some to hang over edges of pan. Spray bottom and sides of foil with cooking spray.

Make and bake brownies as directed on box. Cool completely, about 1 1/2 hours.

Remove brownies from pan using foil edges as handles; carefully remove and discard foil. Transfer brownies to serving platter or cutting board. Tint 1 cup of the frosting with food color, or leave white, as desired to match school color. Spread frosting over top. Tint remaining 1/4 cup frosting to match another school color, or leave white if appropriate. Place in small decorating bag fitted with plain tip, and decorate by piping team name, cheers or logos on top, as desired. Decorate brownies as desired with school-color appropriate candy sprinkles, nonpareils and decorating sugars. Let stand about 30 minutes or until frosting is set.

Cut into 4 rows by 4 rows. Store loosely covered in single layer.
