An electric egg beater, comprising a housing, a motor, a circuit board and a holding device wherein the holding device comprise one or more clamps for holding an egg with eggshell wherein the holding device is configured to be connected to a motor wherein the circuit board is configured to control the motor to rotate clockwise and counterclockwise wherein the motor is configured to drive the holding device to rotate the egg held therein clockwise and counterclockwise in alternation. The electric egg beater enables the egg white and egg yolk to be mixed uniformly and rapidly without breaking the egg shell. No mixing vessel is involved in the mixing, thereby saving the labor for washing and preventing the egg liquid from exposing in the air. The uniformly mixed shell-intact egg can be boiled directly the taste is soft and smooth, and the product is compact and golden yellow, which facilitates the dish carving and creation. In addition, no pure yolk is produced, thereby avoiding the hidden danger of chocking of elderlies and children.
