icing
Icing, also called frosting, is a sweet glaze used to coat and decorate baked goods.
While both icing and frosting are commonly used interchangeably, they're also used to refer to similar but slightly different types of glazes for decorating. Frosting can refer to a thicker type of glaze that is better able to hold decorative shapes, while icing can refer to a thinner glaze that hardens and forms a very smooth coating.
