Don’t eat that! But wait, this slime is OK if a nibble happens! We know some kids are forever going to taste things and some kids are too young to know not to taste everything. Yet, you still want to make some cool slime or putty with them. Bring on a fun edible slime that doubles as a cool putty idea too. Homemade slime is what we love to play with here!
HOW TO MAKE EDIBLE SLIME WITH MARSHMALLOW INGREDIENTS
Taste safe or edible slimes are not something we do a whole lot of but sometimes you just need an alternative to the classic slime recipes that use liquid starch, saline solution, or borax powder.
Note: While this is considered an edible slime, it is not meant to be a food source. I hate to use the word edible because it implies that you should eat it and I am pretty sure this isn’t the healthiest thing to consume. However we are talking about safety, so this edible slime is perfectly fine if a little is consumed.
HOW TO MAKE EDIBLE SLIME WITH MARSHMALLOWS!
SUPPLIES:
6 Jumbo Marshmallows {make a jumbo marshmallow catapult too!}
1 TBL Cooking Oil
1/2- 1 TBL Cornstarch Powder
(CLICK HERE TO MAKE>>> marshmallow slime without cornstarch)
INSTRUCTIONS TO MAKE EDIBLE SLIME:
Note: Adult supervision and assistance highly recommended.
STEP 1: Put 6 marshmallows in a microwave safe bowl.
STEP 2: Pour 1 TBL of oil into the bowl.
STEP 3: Microwave on high for 30 secs. We have a 1200 watt microwave oven so your time may vary slightly.
STEP 4: Add 1/2 tablespoon of cornstarch to heated marshmallows and mix. We used jumbo marshmallows!
STEP 5: This mixture will be HOT so please be very careful! Eventually as it cools, you are going to want to start kneading it and playing with it.
You may want to mix in another 1/2 tablespoon of cornstarch to thicken a little more. The more cornstarch you add, the stiffer it will get and be more like a putty!
The cornstarch will help the marshmallow thicken and form a slime like substance.
PLAYING WITH EDIBLE SLIME!
Stretch it, squeeze it, squish it, and pull it! This edible slime recipe is also awesome for tactile {touch} sensory play and olfactory {smell} sensory play!
Kids will love the way it feels and smells. Read about tactile sensory play here for more great ideas. We have a ton of great sensory play recipes to try out at home like cloud dough and sand foam!
Now this marshmallow edible slime is not as oozy as our traditional slime, but it is stretchy and squeezable! Plus it smells good too. I would say that this also makes a good fidget putty or therapeutic style putty alternative. Find our original putty recipe here.
I certainly don’t blame anyone if they have to take a nibble! It’s good to mix things up and try new things once in awhile. You could also check out this neat marshmallow science activity too.
WHAT HAPPENS WHEN YOU HEAT A MARSHMALLOW?
This edible slime recipe even has a little science to it because of the marshmallows! Have you ever noticed what happens when you put marshmallows in the microwave? They get big and puffy {before they burn if you let them go to long}!
When you heat up a marshmallow, you heat up the molecules in the water that is contained within the marshmallow. These molecules move farther apart. This gives us the squishiness that we are looking for to mix up your Rice Krispy squares or our slime! The added oil does assist in the pliability, and general non drying of the material.
When you add the cornstarch, a natural thickener, you make a thick stretchy substance which is known as the great marshmallow slime! Your hands playing, kneading, stretching, and generally having fun with the slime putty keeps it going.
After a while as the slime cools down, it’s going to harden. The molecules in the water move closer together again. So unfortunately this slime is not going to last all day or overnight. Yes, we put ours in a plastic bin to see.
Our traditional non edible slime recipes do last a lot longer!

Have you used any other thickening agents other than corn starch? I would love to do this with my class but I have a student highly allergic to corn so that rules out corn starch.
littlebins
Powdered sugar is often used in conjunction with cornstarch but I am not sure if it will do the job thickening it on its own. So glad you recognize the allergy though!
Neve
Use powder suger instead of corn starch
Linda
I had a tough time getting the slime off my hands. After kneading, it was stretchy and pliable like you said, but I couldn’t get it off my hands without finally running them under water. Any suggestions?
littlebins
You can add a little cooking oil to your hands. Once you make the slime and the ingredients come together finally. You may want to wash hands once after you initially knead the marshmallow mixture just to remove the residue and then add a little oil to your fingers and palms. This is an alternative slime recipe so you won’t really get that rubbery slime feel, but its great when you can’t use those other ingredients or don’t want to!

Can you use powdered sugar instead of cornstarch?

Yes you can!

OMG, what a great idea! Definitely need to show this to my daughter.
