How long you can keep homemade mooncakes depends on the recipe. Generally speaking, well-made mooncakes can be kept for 7~10 days at room temperature and more than 1 month under refrigeration. If you use mooncakes with high-temperature ingredients such as cream and mayonnaise, they can only be kept for 3~5 days at room temperature and more than 1 month under refrigeration. If you use deep-fried mooncakes, they can be kept for 7~10 days at room temperature and 1~2 months under refrigeration.
