How to Make Dehydrated Marshmallows for Homemade Lucky Charms, Hot Chocolate, and more!

How to dehydrate marshmallows – dry marshmallows for “Lucky Charms” type cereal, hot chocolate, and more!

We live in Africa, and sometimes my kids remember Lucky Charms from the states. Some shops here do have them . . . for $15 per box ! Needless to say, we don’t purchase those due to the cost 🙂 But I can make my own dehydrated marshmallows at home. We add them to some cheerios, and I have some happy kids excited for their special breakfast. They’re perfectly crispy and melt in your mouth without any chew. They are SO good.

And is there anything better than a big mug of creamy hot chocolate with marshmallows on top? Dehydrating marshmallows ensures that you always have marshmallows on hand for that, since they’ll last for a long time in your pantry. We love The BEST Homemade Hot Cocoa Mix recipe because it is so creamy and rich, and easy to make too! Another favorite hot chocolate recipe of ours is Pistachio Hot Chocolate – yummmm. 

Dehydrated marshmallows also make a super fun ice cream topper 🙂 Add them as a topping at your summer ice cream party, or for an easy treat at home, sprinkle them on vanilla ice cream and top with graham cracker crumbs and chocolate syrup for a fun and easy S’mores Sundae. Yum. (Speaking of s’mores – these Mini S’mores Pies  are one of the best little desserts on the planet. No joke.)

  • using a dehydrator is best, but you also can use your oven if you don’t have one. If you are looking for a dehydrator, this Chefman Food Dehydrator is such a good one at a good price. With all the talk of food shortages, it is always nice to know that you have some dried food prepped and stored in the pantry.

  • another option for dehydrating is the Instant Pot Duo Crisp. The Duo Crisp is a pressure cooker, slow cooker, air fryer, roaster, steamer, baker, broiler, dehydrator, and sauté all in one! It really is an amazing appliance.

  1. First, if you are using large marshmallows, cut them into smaller pieces. The smaller they are, the better they will dry. I love to use my kitchen scissors for this, but a knife will work too. You will want to occasionally dust your blade with powdered sugar in order to avoid sticking. If you are using mini marshmallows, no prep is needed!
  2. Put your marshmallows in a single layer on the dehydrating racks. They can be close, but should not be touching. If you have a dehydrator with a lot of racks, that will certainly enable you to dehydrate a large batch of marshmallows at once.
  3. Set your dehydrator to 150 degrees F, and dehydrate the marshmallows for around 8-10 hours. Timing can be pretty broad for dehydrating marshmallows . . . . depending on the humidity in your house and your weather. 
  4. When your marshmallows are done and cooled, you will be able to crush them in your hand and the marshmallow will turn into powder. If your marshmallows are not to this point yet, you need to turn them on for another hour or two, then check again. It’s ok if they’re on the dehydrator for “too long.” It won’t hurt them!


I would definitely recommend the dehydrator instructions for best results, but if you have to, you can turn your oven to the lowest setting, prop the door open, and put your marshmallows on a single layer on cookie sheets until dry. This may take from 2-6 hours doing it this way, check them every 1/2 hour.


For this method, lay your marshmallows in a single layer, and use the dehydrator setting on 150 F for 8 hours. 


  • use ziplock bags
  • or airtight containers
  • or put in ziplock bags, and THEN in an airtight container, if you want them to last as long as possible!

We love these ziplock bags from Amazon! They are such a great price buying them in bulk this way. They are great quality.

Our favorite airtight containers are these sets. They keep our pantry organized, and I love how they keep my foods fresh and protected from humidity.
