Cake decorating is one of the sugar arts that uses icing and other edible decorative elements to make otherwise plain cakes more visually interesting. Alternatively, cakes can be molded and sculpted to resemble three-dimensional persons, places and things. In many areas of the world, decorated cakes are often the focal point of a special celebration such as a birthday, graduation, bridal shower, wedding, or anniversary.

The art of cake decorating dates back to mid-17th century in Europe and has since flourished in many regions and countries, including Northwestern Europe, North America, Australia, New Zealand and South America.

Cake decorating can be a hobby or a job.
