This Edible Marshmallow Fluff Slime is SUPER stretchy!! Made with 3 simple kitchen ingredients for taste-safe sensory play for kids of all ages.
Edible Marshmallow Fluff Slime
Wouldn’t you know it, we had record-breaking rain on the Fourth of July this year!
Since we were stuck inside, my youngest daughter begged to make slime. What a perfect opportunity to try out the new Marshmallow Fluff Slime recipe I’d been working on!
We love edible slime, and I’ve seen marshmallow slime done with regular campfire marshmallows before. However, that adds a step of microwaving and melting the marshmallows, which is something my 4-year old isn’t going to handle on her own. So I decided to try my own version of edible marshmallow slime using marshmallow fluff — which is already in a more malleable form.
Result: a super-duper stretchy edible marshmallow slime that requires no heating or cooking! Not only is this easy marshmallow slime recipe non-toxic…it’s edible! Actually, it tastes pretty yummy! Not that I recommend eating the whole batch, but if your kids lick their fingers it’s all good.
Since marshmallow fluff is sticky, this slime takes a little more kneading/mixing time to reach the perfect consistency – but when it does, it is SO worth it!
Marshmallow fluff slime is one of the stretchiest edible slime recipes we’ve ever made!
Why Edible Slime?
If you’ve seen the slime recipes circulating on social media, then you’ve likely noticed that many of them contain harsh ingredients like borax. These can be irritating to sensitive hands, and they’re not the best idea for toddlers or young kids that still like to taste-test everything they play with.
When the slime craze first hit, my youngest daughter was only 2 years old. That’s why I decided to create SAFE edible slime for my girls to enjoy. Our first and most popular recipe — Edible Jello Slime — was such a smash that we decided to try other ingredients too!
Slime is a wonderful sensory activity and very soothing for kids (and grown-ups too!) Our edible slime recipes are all simple (most are 2-3 ingredients) and made with safe, food-based ingredients that are easy to find. In fact, you might already have many of the items we used in your own kitchen.

How to Make Edible Marshmallow Slime
Watch this 1-minute demo video to see how it’s made, then keep reading for full step-by-step instructions, play ideas, slime safety tips, and more!
Add marshmallow fluff, powdered sugar, and 1/4 cup cornstarch to mixing bowl. Stir together until flour and sugar mix into marshmallow.
Add remaining 1/2 cup cornstarch little by little, and finish kneading by hand. (If slime is still too sticky to play with, continue to work in cornstarch 1 teaspoon at a time).
TIP: Coat hands with coconut oil before kneading and/or playing to prevent slime from sticking to hands until you’ve reached just the right ratio of marshmallow fluff to corn starch.
If slime thickens while you play, simply microwave for 5-10 seconds to soften.

Slime Making Tips
- We used a silicone baking mat as our play surface for easier clean-up. (Marshmallow slime washes right off with water!)
- You can’t really “mess up” making this recipe. If it’s too sticky, simply add more cornstarch. If it’s too thick, add a bit more marshmallow fluff or a bit of water.
- Add food coloring for custom marshmallow slime in a rainbow of colors!
- Just a note: this putty is taste-safe, but it’s not a food item and not meant to be eaten in large amounts. Always supervise young children when playing with this silly putty.
Slime Storage Tips
- Keep refrigerated in an airtight container for 2-3 days. Heat in microwave for about 10 seconds, add a teaspoon of water and squish to rehydrate for more play time!
- Always wash hands before playing with slime to help keep it clean.
- Since this is a food item, it is perishable; check for signs of mold before reusing.
Slime Safety Tips
While this marshmallow slime recipe is technically edible, it’s not meant to be consumed as food. Always supervise kids when playing with slime, even taste-safe slime.
