How-To: Dehydrating Marshmallows

Marshmallows, when dehydrated, make yummy snacking treats for both young and older kids. Use them in hot cocoa, cereals (both hot and cold), and baking too!

Just an FYI: some people have tried this with homemade marshmallows and they had varying results. A few said they melted on the trays. The recipes containing stabilizers (like gelatin) work best.

Dehydrating any marshmallows left over from an open bag you didn’t completely use will avoid their becoming stale.

Once the water evaporates and they become crunchy, the marshmallows keep almost indefinitely. Store dehydrated marshmallows in an airtight container at room temperature for up to a year.

Because home-dehydrated marshmallows don’t shrink much in size, cut large marshmallows into tiny pieces before dehydrating them for use in snack mixes, or as bite-size candies.

Dehydrated marshmallows flake and crumble if you try to cut them after they’re dried.

Cut larger marshmallows to smaller sizes: For the regular marshmallows, cut them into 4-8 smaller bits to dry faster. The mini-marshmallows may also be cut in half if you wish.

Lay them out on a tray in a single layer. Make sure marshmallows aren’t touching so there aren’t spots where they may not have dried well.

Dehydrate at 125°F/50°C for 6-12 hours, depending on the sizes or until they are completely crunchy. The crunchier they are in the end, the better for storage.

To test dryness, take a few pieces out of the dehydrator and put on a plate. Allow to cool.If they are completely crunchy (like the marshmallows in Lucky Charms cereal) then they are dry and ready to cool for storage.

Store in an airtight container as soon as they cool.If not sealed up right away, they will soften quickly.

Note: the size will not change from the un-dehydrated state.
