Ice cream is a dessert made from frozen milk or cream. Icecream is usually flavoured with sugar, vanilla, fruit or chocolate. Icecream is made by freezing the milk or cream slowly and stirring it frequently so it stays smooth. If you don't stir it, it will be full of crunchy ice crystals and will not be as nice. Icecream is sometimes served in a cone.
Icing, or frosting, is a very sweet decorative layer that is put onto cakes and cookies. Icing can be made into any color, and varies from a soft spread to a very hard consistency. Icing is most commonly made from a mixture of icing sugar and butter, with coloring and flavors added.
