So, if you are curious about the process of dehydrating marshmallows, then grab a couple of bags of marshmallows and follow the step-by-step guide given below:

If you want your marshmallows to dehydrate faster, then the best approach would be to cut them into smaller pieces. The big pieces of marshmallows can be dehydrated. However, it will take you quite a lot of time. In order to cut the marshmallows into smaller sizes, all you will need is a knife and a wet cloth to wipe off the powdered sugar from the knife. If you do end up cutting the marshmallows, remember that there won’t be any specific shape to them anymore; however, it will save hours of your time.

Put marshmallows in a dehydrator tray

Something that is absolutely crucial for you to remember is that you have to lay the marshmallows in a single layer. Also, you need to make sure that the marshmallows are evenly spaced out from each other. They shouldn’t be in touch with one another.

If the marshmallows come in contact with one another, then chances are they will stick together. Since marshmallows seem to move around a lot, you will have to be extra careful. One dehydrator tray can fit up to half a bag of marshmallows while having plenty of space in between them.

Dehydrate Marshmallows in a dehydrator

Next, place the dehydrator tray with the marshmallows inside the dehydrator. Of course, before that, you need to set the dehydrator at around 150°F / 62°C. The time it will take to dehydrate your marshmallows depends on how big they are. Along with that, the humidity level of the atmosphere of your house and the strength of your dehydrator has also come into play.

Mini marshmallows usually take about 4 to 12 hours, whereas the larger marshmallows take around 10 to 24 hours. Keep in mind that there is no such thing as dehydrating marshmallows for too long. If you want to make marshmallow dust, then keep them in the dehydrator for more than 24 hours, and you will end up with dehydrated marshmallows, which are perfect for making marshmallow dust.

Decreasing the temperature for big or brightly colored marshmallows to 125°F/35C may help avoid some of the puffing that takes place with marshmallows such as Peeps marshmallows or any other fancier marshmallows.
