How Long Do Marshmallows Last? Do They Go Bad?

As a food lover, you’ve certainly encountered marshmallows in some form or another.

Maybe you’ve toasted them for the perfect s’more or melted them into your favorite hot cocoa recipe!

But have you ever stopped to think about how long they last before going bad?

That question isn’t so straightforward as it may seem.

Marshmallows are quite unique and certain storage requirements must be met in order to preserve their integrity — otherwise, the candy can quickly become stale and spoil.

In this blog post, we will go over the shelf life of marshmallows, give tips on how to store them correctly and answer some common questions about marshmallow edibility.

So let’s get started exploring these delicious treats!

What’s Marshmallow?

Marshmallow is a sweet, fluffy confection that is often used in desserts and as a topping for hot cocoa.

It is made from sugar, corn syrup, water, gelatin and flavorings.

Marshmallows are low in calories and fat, but they are high in sugar.

How Long Do Marshmallows Last?

Marshmallows are one of those classic American sweets that have been around for generations.

Whether you’re roasting them over a fire, using them in a recipe or just eating them straight out of the bag, marshmallows are always a good treat.

But how long do marshmallows last? The answer to this question is not as straightforward as you might think.

Marshmallows are made with sugar, corn syrup and gelatin, which means they don’t contain any water.

This makes them resistant to mold and bacteria, but it also means they can dry out quickly if they’re not stored properly.

Ideally, marshmallows should be stored in an airtight container in a cool, dry place.

If you’re planning on using them within a few weeks, they can just be stored in the pantry.

However, if you want them to last longer than that, it’s best to store them in the fridge or freezer.

When it comes to shelf life, marshmallows will last for 2-3 months when stored in the pantry, 6-8 months when stored in the fridge and up to a year when stored in the freezer.

Of course, these are just guidelines and your marshmallows may last even longer if they’re stored properly.

So there you have it. Now you know how long marshmallows last and how to store them so they stay fresh for as long as possible.

How to Store Marshmallows?

Marshmallows are a versatile treat that can be enjoyed in many different ways.

You can roast them over a fire, use them in hot cocoa or simply eat them straight out of the bag.

But no matter how you enjoy them, you’ll want to make sure they’re stored properly so they stay fresh and delicious.

The best way to store marshmallows is in an airtight container.

This will keep them from drying out and becoming hard.

If you’re planning on using the marshmallows within a week or two, you can just store them in the pantry.

But if you want to keep them for longer, it’s best to store them in the fridge.

If you’re going to be storing marshmallows in the fridge, make sure to put them in a zip-top bag so they don’t absorb any moisture from the air.

Marshmallows can last for up to three months when stored this way.

Just be sure to let them come to room temperature before enjoying so they’re nice and fluffy.

How to Tell If Marshmallows are Bad?

There are a few ways to tell if marshmallows are bad. The first way is to look at them.

If the marshmallows are discolored or have any mold on them, then they are bad and you should not eat them.

Another way to tell if marshmallows are bad is by smelling them.

If they have a sour or unpleasant smell, then they are also bad and should not be eaten.

Finally, you can try squeezing a marshmallow.

If it is hard or dry, then it is probably bad and you should not eat it.

Can You Freeze Marshmallows?

Yes, you can freeze marshmallows. Marshmallows are actually quite versatile when it comes to freezing.

You can freeze them whole, in halves, or even in quarters.

The key is to make sure that they are properly sealed so that they don’t dry out.

When freezing marshmallows, it’s best to use an airtight container.

You can also wrap them tightly in plastic wrap or aluminum foil.

If you’re using a container, make sure to leave some space at the top so that the marshmallows have room to expand as they freeze.

Once they’re sealed up tight, pop them into the freezer and let them do their thing.

Frozen marshmallows will last for about two months before they start to lose their flavor and texture.

So if you find yourself with a surplus of marshmallows, don’t hesitate to throw them in the freezer and save them for later.


So, do marshmallows go bad? The answer is yes, they can.

But if you store them properly, they can last for a very long time.

Marshmallows are a great treat to have around, so make sure you keep them in a cool, dry place and they’ll be good to enjoy for a while.

Thanks for reading and enjoy your sweet treat.
