How To Make Edible Slime – The Nontoxic Way

Slime can get really messy and can be complicated to make if you don’t know what to do. I am here to make it easy enough for you to do this with your child, with your friend, or whomever. This is a great and easy slime recipe for kids as long as there is an adult present to make sure there is no funny business. I will be showing you how to make marshmallow slime.

What is needed to make marshmallow slime?

  • 1 Cup Cornstarch
  • 2 – 3 Cup Marshmallows
  • 2 1/2 Teaspoons Oil of your choice
  • Scented flavoring (optional)
  • Food coloring (optional)
  • Confectionate sugar (optional)

I bet you thought marshmallow slime would just contain marshmallows. Well, it can. If you want the stickiest slime ever, all you need to do is microwave about two cups of marshmallows for under a minute. All the chunks will become one mass and there you have it – a sticky big lump of marshmallow slime. Now, I personally don’t like my hands or face feeling sticky, so if you want to be in the same boat as me, let’s keep it moving.

Directions – Let’s Get Messy

…. Or not. It’s really up to you. You can either prepare everything ahead of time and have your young one(s) mix the ingredients in a bowl or you can show them the entire procedure and turn it into a longer science experiment. Do what works best.

Here are the steps:

  • Microwave 2 to 3 cups of marshmallows for under a minute
Jumbo Marshmallows

  • Add 1 1/2 teaspoons of the oil of your choice

  • Mix the melted marshmallows with the oil using a spoon
  • Add a cup of cornstarch a little at a time and continue to mix
  • You will notice the slime growing thicker and less sticky. You can add one more teaspoon of oil to the mixture if you so choose to lessen the stickiness
  • You can remove the mixture from the bowl and begin molding with your hands

  • There you have it – your edible slime.

If you want to add color or flavor, you can also add a vanilla powder or any food coloring you want.  In mine, I added 7 drops of yellow food coloring and 1/2 teaspoon of raspberry extract for a tiny hint of flavor.  If you do want to go with flavoring, add dry flavoring to prevent your slime from being sticky. With a dry flavoring, you can add a teaspoon of your desired spice.

Now you can make your own slime!!! Go to it and show everyone what you know. Have a slime making competition and remember, you can always tweak the recipe. If you would like to see other slime recipes be sure to let me know.

  1. I’ve never made edible slime before but it sounds like a great idea! One idea I can think of is making green slime for Halloween for the trick or treaters that’s mint flavor, in honor of Ghostbusters 🙂

    1. Thank you for your comment, Tom. Halloween is not too far around the corner. Since you put it out there, how about some glow in the dark edible slime? Look out for the recipe. It should be coming in the near future!

  2. Wow! Interesting topic, i have a 11 yrs old and she loves to make Slime, Your information is very educational and well informative..She love to eat Marshmellow , so now she will be happy to know she can actually make slime from them the non- toxic way. Indoor games to play with kids are enlightening, at times when rain is falling they at times get pretty board and can annoy the heck out of you, so with all these great ideas , parents can apply them very well to their kids lives.

    1. Awesome! If your 11 year old ends up making it, let me know how it goes! I would love to hear about her experience. What kind of slime has your daughter made?

  3. Wonderful idea and it’s edible too! We are having nieces and nephews over this weekend so I’m thinking this will be a great idea to prepare ahead of time. Do you know how long it will stay slimy? Should I put it in the refrigerator or freezer if I don’t use it right away?
    Amazing site, so helpful…keep giving the fantastic advice.

    1. Wonderful! That sounds exciting! Please share their experience if you all end up making it. I should also remind you, this slime is fluffy. If you want it to be more slimy, just use melted marshmallow and the oil. I will be posting another slime recipe soon featuring my little sister. Keep an eye out for it.
