Cake toppings can include icings and ices. Icings are a type of topping that is usually made from sugar, butter, and milk or cream, and is used to cover the top and sides of cakes. Ices are a type of topping that is usually made from sugar, water, and flavoring, and is used to create a thin layer on the top of cakes. Both icings and ices can be used to add flavor, color, and texture to cakes.
