How to Make Marshmallow Slime in Less than Five Minutes
Follow along with these directions and learn how to make marshmallow slime with kids!
Note: This slime will get hard after a few minutes of play. That is normal and does not mean you did something wrong when making the slime. When the sugar from the marshmallows gets heated, it will slowly turn from a slime-like texture to a regular candy-like texture, similar to how taffy gets less sticky over time.
- Marshmallows (both mini marshmallows and jumbo marshmallows work)
- Microwaveable bowl
- Cornstarch or powdered sugar
- Vegetable oil (optional)
- Food coloring (optional)
- Sprinkles (optional)
How to make the Marshmallow Slime
Follow these easy directions to make marshmallow slime in less than five minutes!
Fill a microwave-safe bowl with marshmallows.
Heat in the microwave at 30-second intervals. The marshmallow mixture will melt into a mixture that resembles a sticky dough, then stir the marshmallows together in the mixing bowl between heating sessions.
If you want your white marshmallows to be a different color you can add food colouring to the melted marshmallows.
As soon as the marshmallows start to pull together into one single lump, do not heat any more.
If you heat the marshmallows too much in the microwave, they will harden and then burn, turning into a hard, brown substance that is quite hard to clean (ask me how I know!).
Pour in about 1 TBSP of vegetable oil (like coconut oil or olive oil) to the marshmallows and sprinkle a few drops of food coloring onto the marshmallows. Mix with your fork.
The marshmallow slime will get harder slowly over time, and the oil helps delay this process and makes mixing the slime easier.
Here is the part that will determine whether your marshmallow slime is edible or not edible…
If you want it to be taste safe but not necessarily edible, then use 1 tablespoon cornstarch.
If you want it to be edible, use powdered sugar.
Taste safe but not edible: Add a tablespoon of cornstarch to the slime and continue to mix with your hands.
You should be left with a slime mixture that pulls easily, doesn’t stick to the hands (but is a bit sticky like candy), and is a little stiffer than slime made with glue.
Edible Marshmallow Slime: Add 2 TBSP of powdered sugar to the mix instead of cornstarch.
The marshmallow slime will be a bit stickier when using powdered sugar so you may need to add a little more powdered sugar until it reaches your desired consistency.
If you like, press some sprinkles into the surface of the slime for some fun, edible texture!
Let the kids play with the slime until it hardens. Once it hardens, the kids can eat it, as this slime is completely edible!
But fair warning, this slime is *very* sweet. It made my teeth ache when I took a bite! But kids love it and it’s a great sensory activity that keeps them interested!
