A food shaping device for forming a three-layered food comprises: at least two first guide units and a food output unit. The food output device comprises a main tube; a middle tube; an inner tube; an inner circular path; an inner material guiding nozzle; and an outer material guiding nozzle. Stuffing is filled into a second guide unit; then the stuffing is pushed to the output end of the inner tube by a screw propeller to be as an inner layer material. Dough is fed into the inlets of the main tube from the two first paths and then is further processed to be as an outer layer material of the food product. A part of the dough horizontally passes through the transversal inlet of the middle tube and is further processed to be as a middle layer material. Thus a three layers food is formed.
