Poured Fondant Icing
This frosting is the traditional coating for baked goods like petits fours. It can be tinted any color you like, and makes a lovely, slightly sheer glaze over a cake or cupcakes. Work with it warm, and simply pour it over whatever you're planning to frost. The excess can be remelted and strained of crumbs to use again; or poured into molds to make candies.
