Abstract
Abstract Cake is continuously baked without the use of baking pans by the extrusion of batter into a shaped baking chamber disposed in a microwave cavity. The product is moved through the baking chamber by maintaining the batter under pressure, by the use of conveyors, or by a reciprocating piston. In one embodiment, a filled cake product is produced by continuously and concurrently extruding a confectionery material into a cavity formed in the cake product during the baking process.
