We are loving edible slime in our house right now. I have a new recipe for you today: an Edible Marshmallow Slime recipe! This one is based on the homemade marshmallow fondant I like to make for cake decorating. It is a kid favorite now! It is so fun to play with.
Ingredients for Edible Marshmallow Slime
1 Bag of Mini marshmallows or jumbo marshmallows
1/4- 1/3 cup Coconut Oil or any vegetable oil -add more to make it less sticky
1/2 cup Powdered Sugar
Rainbow Sprinkles or Edible Glitter Stars– optional but fun! We added 1-2 Tbsp.
You could also add food coloring if you want it to be colored!
Large microwave safe bowl
How to Make Marshmallow Slime
Pour the whole bag of marshmallows into a large microwave safe mixing bowl. Microwave for 30 seconds and stop. Mix the marshmallow mixture, then repeat in the microwave. Two times was enough for our marshmallows to be entirely melted. Stir until the marshmallows are all dissolved.
Add in the powdered sugar and 1/4 c. of oil. Mix well.
Let it cool for about 15 minutes. Coat your hands in some of the remaining oil and mix by hand. It will be really sticky, but you can continue adding a little oil until it can be held and played with without sticking entirely.
Mix in 2-3 Tablespoons of rainbow sprinkles. The color bleeds a bit as you mix it in, and it looks really cool and colorful this way!
It is completely taste safe, fully edible. So go ahead, play, and eat. Whatever makes you happy! (This is surprisingly delicious- I mean, marshmallows, come on!)
How to Make Slime Less Sticky
These edible slimes are a LOT more sticky than regular slime since they are made of sugary foods. Sugar is naturally going to be really sticky. They are best played with on a washable surface!
If you want to make your slime less sticky, it helps to coat your hands in some oil or shortening if you still have any of that stuff hanging around. 😉 If your slime is still too sticky, you can also dust the marshmallow slime with a little corn starch to make it a touch less sticky.
This slime was really stretchy on the first day, the second day it was less stretchy, but also a lot less sticky. You can see the difference in texture on the second day. Both were fun to play with.

This slime is awesome and I reccomwnd this to anyone who has kids or just anyone in general
How do you heat it if you don’t have a microwave?
Karyn Tripp says
You can do it in a pot on the stove, too!
I would love to do this with my students as a fun Friday activity. About how much does this recipe make of Marshmallow slime. I have 17 students and just wanted to see how I could do this. GREAT PROJECT ! I look forward to hearing from you.

You will definitely want to make more for a larger group. You can see the amount it made in the picture where I hold it in my hands. It was a large ball, but for 17 kids, you would probably double or triple this recipe. Have fun!
How do I store the marshmallow slime? And how long did yours last?
This was fun but so sticky!!! Halfway through we put our hands in plastic bags and nothing stuck!
We still had the sensory experience but less messy
Thanks for sharing!
