To do this best, keep them in an air-tight container at room temperature and out of sunlight – these two steps helps to keep the crunch and flavor intact.

How Long Do M&Ms Last?

Many people have been enjoying the delicious snack of M&Ms for decades, and one question that has many people scratching their heads is: how long do M&Ms last? The answer depends on the specific type of chocolate being discussed.

If it’s sealed in its packaging, it can last for up to a year – although this could be influenced by the storage conditions.

Unopened packages or bars will typically stay fresh between two and four months after the manufacturing date.

Nuts, peanut butter, and other crunchy fillings could potentially last longer because they help keep air out due to their harder consistency.

Once opened, however, M&Ms should be consumed within three weeks if left at room temperature, otherwise they may start to dry out.

All in all, there are quite a few variables involved when it comes to the shelf life of your favorite chocolate treats.

Many people wonder if they can freeze M&Ms in order to make them last longer or simply enjoy a refreshing treat.

The length of time which M&Ms can be frozen varies but you should check on them about every three months for signs of staleness.

It’s recommended that you store the candies in airtight plastic bags or containers as this will help to protect them from any other flavors lingering in your freezer.

All in all, freezing M&Ms is an easy way to preserve their freshness and enjoy at a later time.
