Carrot cake stays fresh for up to 2 days when stored in an airtight cake container or storage bag at room temperature, and up to 6 months in the freezer. The refrigerator gives the cake about 1 additional week of freshness when wrapped effectively. Frosted cakes keep best because icing acts as a seal to retain moisture. However, most varieties of frosting do not lend themselves well to freezing and thawing, so freeze carrot cake unfrosted and decorate it after it thaws.
