Expiration & Storage Tips
When does frosting expire?
Unopened store-bought frosting typically has a shelf life of about 3-4 months after the printed date on the package. Once you've opened it, it can safely remain in your refrigerator for another 2-3 weeks. Homemade frosting can generally last in the fridge for up to 2 weeks. Frosting can also be stored in the freezer for up to three months.
How do you tell if frosting is bad?
If your frosting has started to develop an odd smell, change color, or grow mold, then it’s time to toss it out. Also, if the texture of the frosting has drastically changed—for example, if it has become watery or grainy—it may be spoiled. Always trust your senses: if it smells off, looks odd, or tastes strange, it's best to avoid using it.
Tips for storing frosting to extend shelf life
• Always store frosting in the refrigerator, even when the container has not been opened. Not only does this significantly increase the shelf life, it also maintains the frosting’s texture and taste.
• If you need to store your frosting for longer periods, consider freezing it. Just make sure to defrost it in the refrigerator, not at room temperature, to avoid condensation.
• Using a clean, dry spoon each time you scoop out some frosting can prevent introducing bacteria into the container which can reduce its shelf life.
• Keep your frosting well-sealed. Air exposure can make it dry out and lose its freshness quickly.
