An electric scone machine or steak machine comprises hinge-connected upper and lower bakeware bodies (1, 2). The upper and lower bakeware bodies (1, 2) consist of upper and lower metal housings (101, 201) and upper and lower heating plates (102, 202). The upper and lower heating plates (102, 202) are correspondingly mounted in the upper and lower metal housings (101, 201), and are formed in a manner that baking hot surfaces (102-1, 202-1) of the upper and lower heating plates (102, 202) are opposite to each other when closed. Nonmetallic disk-shaped upper and lower heat insulating housings (103, 203) are disposed between the upper metal housing (101) and the upper heating plate (102) and between the lower metal housing (201) and the lower heating plate (202) respectively. The upper and lower heating plates (102, 202) are embedded in cavities (103-1, 203-1) of the upper and lower heat insulating housings (103, 203) respectively, and have opening edges (102-2, 202-2) borne on support surfaces (103-2a, 203-2a) of extended support platforms (103-2, 203-2) of openings of the upper and lower heat insulating housings (103, 203). Opening edges (101-1, 201-1) of the upper and lower metal housings (101, 201) abut against another end surfaces (103-2b, 203-2b) opposite to the support surfaces (103-2a, 203-2a) of the extended support platforms (103-2, 203-2). Outer end surfaces (103-2c, 203-2c) of the extended support platforms (103-2, 203-2) extend out of outer sides of outer end surfaces (101-2, 201-2, 102-3, 202-3) of the upper and lower metal housings (101, 201) and the upper and lower heating plates (102, 202). The electric scone machine or steak machine of this structure has a simple and reasonable structure, and has the desirable heat insulating effect.
