How to Keep Marshmallows Fresh

Marshmallows are made from a mixture of sugar or corn syrup, gelatin and water. The ingredients are whipped together to create the spongy marshmallow texture. When you purchase a bag of marshmallows, it can be difficult to consume the entire package. Instead of throwing the leftover marshmallows away, store them in the pantry or freezer to keep them fresh. Roast the marshmallows over a campfire, create marshmallow treats or place them in a cup of hot chocolate.

  1. 1

    Remove the marshmallows from the original package once you open them.

  2. 2

    Place the marshmallows into an airtight container. Sprinkle icing sugar over the marshmallows. Shake the container to coat the marshmallows to prevent them from sticking together.

  3. 3

    Store the container in a cool and dark location, such as the refrigerator, for 2 to 3 months.


  1. 1

    Pour the marshmallows into an airtight freezer container or plastic storage bag. Avoid packing too many marshmallows into the container or bag because it will squish them together.

  2. 2

    Place the marshmallows into the freezer. Keep them frozen until you need to use them.

  3. 3

    Remove the marshmallows and thaw them at room temperature. The marshmallows will defrost in 5 minutes or less. Use the marshmallows within 3 to 4 months for best results.

Tips and warnings

  • Throw away marshmallows that have an odd odour or colour.
  • It is important to chill or freeze marshmallows after you purchase them because they will stick together as they age in the pantry.
