Abstract: A convertible and folding cooking pan includes a base plate and a plurality of pivotable and adjustable flanges removably coupled thereto. The flanges are moveable from a first substantially flat position to a second substantially upright position. When in the substantially upright position, the flanges are securely connected to define a baking zone with base plate and the flanges. In one embodiment, a plurality of sets of flanges are configured on the base plate to enable the selectable configuration of a first baking zone using the first set of flanges or a second, differently-sized baking zone using the second set of flanges.
