Expiration & Storage Tips
When does kit kat candy bar expire?
Usually, a Kit Kat bar can last a while if you've stored it properly. In an unopened package, a Kit Kat is typically good for about 9 months to a year. If you've already opened the package but didn't finish it, it's good for about 2-3 months. If, by chance, you froze your Kit Kat candy bars, they could last up to a year in the freezer before quality starts to degrade.
How do you tell if kit kat candy bar is bad?
The most definite sign that your Kit Kat has gone bad is if it has a foul smell or mold growth. But, normally, the first sign is a change in the chocolate's appearance. Look for a powdery, white coating on the chocolate. This is called 'bloom' and occurs when the fat or sugar in the chocolate rises to the surface. While bloom is not harmful, it indicates that the texture and taste may have changed. Not necessarily rotten, but it won't taste as good.
Tips for storing kit kat candy bar to extend shelf life
• Keep your Kit Kat candy bars in a cool, dry place. Exposing them to heat or moisture can speed up the blooming process.
• If the candy bar is opened, try to wrap it in aluminum foil or keep it in a Ziploc bag to keep it fresh.
• Believe it or not, you can freeze Kit Kats! This can extend their shelf life, and many people enjoy the crunchy texture of frozen Kit Kats. If doing so, keep them in a freezer bag and defrost in the fridge before eating.
