Abstract
An improved, multi-purpose cake pan which offers the flexibility of having both a flat-cake pan and a tube-cake pan, the compact storageability of a single cake pan, and a simplified means of removing either a flat-cake or a tube-cake from the outer rim of the cake pan itself. Two separate cake pan insets are provided to allow the cake pan user to bake either a flat-cake or a tube-cake. Both such insets fit securely into an outer rim--giving the appearance of a standard, one-piece cake pan. A tube-cake handle quickly connects to the tube-cake inset and allows it to be easily removed from the outer rim of the cake pan. A quick procedure for removing the flat-cake inset is performed by simply lowering the cake pan over the tube-cake inset whereby a vertical column of the tube-cake inset pushes the flat-cake inset up and out of the outer rim of the cake pan.
