Cake decoration involves using icings, frostings, and other edible decorations to improve the visual appeal and flavor of cakes. Common cake decoration techniques include buttercream frosting, royal icing, marzipan, sugar paste, flower paste, glace icing, ganache, and fondant icing. Basic tools for cake decoration include cake pans, parchment paper, knives, cake boards, spatulas, and fondant rollers. Properly decorated cakes can be kept fresh by sealing in moisture with buttercream or fondant, refrigerating unfinished cakes, and storing elaborate cakes in separate layers.
