How long does store-bought cake last in the freezer?
Store-bought cake keeps 6 months in the freezer at 0°F. Food kept frozen at 0°F stays safe indefinitely, so that time is about quality: after it, texture and flavor start to suffer. Wrap it airtight, or vacuum seal it, to prevent freezer burn, and thaw in the refrigerator.
