Abstract
The invention concerns a baking pan assembly for forming a cavity in a muffin to which a filling may be subsequently added. The recessed cup portion of a baking pan is provided with a keyed-orifice. A conical or other symmetrical insert having a key mate with the orifice, such that the insert is centrally located in the recessed cup bottom. Alternately, single use conical or other symmetrical inserts may be placed in the recessed cup, made of paper, foil, heat resistant plastic, etc. A retaining plate may be positioned above the pan if desired to restrain the batter as it rises to form a flattened surface opposite the cavity for perfect stability once the muffin is inverted.
