- How long does frozen cake last? The precise answer to that question depends to a large extent on storage conditions - keep cake frozen at all times.
Properly stored, frozen cake will maintain best quality for about 12 months in the freezer, although it will usually remain safe to eat after that.
Is frozen cake safe to eat after the expiration date on the package? Yes, if properly stored - commercially frozen cake will typically carry a “Best By," "Best if Used By," “Best Before”, or "Best When Used By" date but this is not a safety date, it is the manufacturer's estimate of how long the frozen cake will remain at peak quality.
How long will frozen cake remain safe to eat? Frozen cake that has been kept constantly frozen at 0°F will keep safe indefinitely, as long as it has been stored properly and the package is not damaged.
How to tell if frozen cake is no longer good? If dry spots or discoloration have developed on the frozen cake, freezer burn has begun to set in - this will not make the cake unsafe to eat, but it will harm the texture and taste.
