The invention relates to low density ready-to-spread frosting compositions and related methods. "Icing" and "frosting" are terms conventionally used to identity spreadable, semi-solid confectionery products that are applied as toppings to sweeten and decorate baked goods such as cakes, breads, cookies, and the like. Generally, icings and frostings can be categorized into several basic types depending in part on whether a particular product contains fat (generally shortening) or not, and whether or not the product is aerated.
