  • Patent number: 5045333
    Abstract: A container of ingredients for an iced bakery good, and a method of icing a bakery good. The container comprises a first compartment which can hold batter or dough which can be frozen or cooled, and can hold the batter or dough during baking, or can also hold a prebaked bakery good. A second compartment is removably attached to the first compartment and has a layer of icing, which can be frozen or cooled, on a surface thereof. After baking the batter or dough in the batter compartment, or heating the pre-baked good, to form an uniced bakery good, the bakery good can be iced by orienting the second compartment over the first compartment with the layer of icing facing a surface of the uniced bakery good. Heat rises from the baked good and heats the icing. The icing separates substantially from the suface of the second compartment and coats a substantial portion of the bakery good surface.
