Of all the edible playdoughs that I make for the kids, this one is the easiest. We almost always have marshmallows in the pantry, so everything is on hand keeping us from making another trip to the store.

This marshmallow recipe for kids is really fun. It’s basically a marshmallow fondant that the kids can play with in fact it’s almost exactly the same as a fondant recipe too.

Tips for making edible playdough with marshmallows

I don’t have any tips for making it, but to the parents out there I do have cleaning tips to read before proceeding!

The good news is that this marshmallow playdough sticks to anything, it should be water soluble, meaning that you can simply soak it in water to dissolve the sugars and clean up the mess.

Word of caution though, if you use food coloring, never use warm water to clean this playdough off of fabric. It will cause the colors to set. Cold or cool water is best!

What is I don’t have cornstarch?

If you don’t have cornstarch on hand you can use powdered sugar instead. This definitely adds sugar content to this playdough but the two work the same in helping to thicken this gluten free playdough recipe.

How long is marshmallow playdough good for?

Depending on how it is played with and stored it can last a long time! At least a few weeks, if not more. I recommend not trying to set a world record for keeping it though as germs do build up from kids’ hands and surfaces. If the children are likely to eat this dough, refresh playtime with a new batch every so often.

How to make marshmallow playdough

  • Combine all of the ingredients in a bowl and then place that bowl in the microwave.
  • Microwave for 15-30 seconds depending on the size of your marshmallows. Just until the marshmallows start to expand.
  • Once finished, stir them down and continue to stir past the stickiness.
  • Once cooled enough to handle, use your hands to knead the dough until it feels like dough. Slowly add in more cornstarch if needed being careful not to add in too much.
