One way to both feed and entertain your party guests is to let them decorate their own cupcakes. Put out various kinds of frosting, sprinkles and other toppings and allow the kids to get creative. Some stores sell edible cake decorations shaped like flowers or letters that you can use, but miniature marshmallows and chocolate candies also serve as easy toppings kids will love. This kind of decorating can get messy, so it may be better to do this activity at smaller parties where things are less likely to get out of hand (and onto the counter and floor). You'll also want to make sure you have multiple aprons to keep your guests from staining their clothes.
