Do n't move If the cake is unfinished flour cake or dough, it needs to be stored in the frozen layer of the refrigerator. When the finished cake is put into the freezing layer, the flour cake or dough will not freeze, which is also beneficial to preservation. If it is frozen, it is best to keep it for a long time, not too long, not more than 1 month. Hand-grabbed cakes have a shelf life.
