How Long Does Canned Frosting Last Once Opened?

Shelf Life Tips

• How long does a can of frosting last once opened? The precise answer depends to a large extent on storage conditions - keep opened frosting refrigerated and tightly covered.
• To maximize the shelf life of canned or packaged frosting after opening, refrigerate in a covered glass or plastic container.
• How long does opened canned frosting last in the refrigerator? Frosting that has been continuously refrigerated will keep for about 3 to 4 weeks.
• Is canned frosting safe to use after the "expiration" date on the package? Yes, provided it has been stored properly, the package is undamaged, and there are no signs of spoilage (see below) - commercially packaged frosting 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 frosting will remain at peak quality.
• To further extend the shelf life of opened canned frosting, freeze it: to freeze frosting, place inside covered airtight containers or heavy-duty freezer bags.
• How long does canned frosting last in the freezer? Properly stored, it will maintain best quality for about 3 months, but will remain safe beyond that time.
• The freezer time shown is for best quality only - frosting that has been kept constantly frozen at 0°F will keep safe indefinitely.
• How long does canned frosting last after being frozen and thawed? Canned frosting that has been defrosted in the fridge can be kept for an additional 3 to 4 days in the refrigerator before using; frosting that was thawed in the microwave or in cold water should be used immediately.
• How can you tell if opened canned frosting is bad or spoiled? The best way is to smell and look at the frosting: if the frosting develops an off odor, flavor or appearance, or if mold appears, it should be discarded.
• Discard all frosting from cans or packages that are leaking, rusting, bulging or severely dented.
