If you are hosting a party and want to give  fun party  favors to your guests, decorated cookies are the perfect confection for the job. Highly customizable, you can make cookies in all shapes, sizes, flavours and colours. They can also serve several functions: make holes in the tops before baking, and your cookies can now be ornaments or name tags. You could also use decorated cookies as place setting cards.  All you really need to know is how to make Royal Icing.
