Mix brownies according to manufacturer directions. For each half sheet of brownies, deposit 3 pounds 8oz batter to a lined and greased tray. Bake until completely set. Let cool completely. Place in cooler overnight. The next day using a football shaped cutter, punch out football shaped brownies. Save the scraps for cake pops or Hamburger Cupcakes. Using the Holland crème with a basket weave tip, pip each curved end of the football, pipe the laces with a small star tip.
