The moon cakes are baked and cooled in the isolated gas environment, the moon cakes are isolated from the air, baking is performed in the oxygen-free environment, so that an oxidation reaction of grease in the moon cakes can be effectively inhibited from generating oxidation deteriorated substances harmful to health; and the moon cakes are baked in the environment isolated from the air, the content of oxygen residues and the oxidation deteriorated substances in the moon cakes is extremely small, the oxygen absorption capacity of the moon cakes is reduced, and the shelf life of the moon cakes is increased by 0.5 time or more. The invention also discloses baking equipment. The bakingequipment includes a baking device and a gas supply device, the gas supply device supplies the preset gas to the baking device to form the isolated gas environment composed of the preset gas in the baking device, the isolated gas environment is isolated from the air, the moon cakes are baked and cooled in the isolated gas environment, the content of the oxidation deteriorated substances and the oxygen residues in the moon cakes is small, and the moon cakes are easier to store.
