Note: This may be easier to mix in small quantities.

  • A container of Marshmallow Fluff
  • Powdered Sugar
  • Food Coloring


Let’s get started with our edible marshmallow fluff slime recipe, and see how my slime making expert Char enjoyed making it for us! 

  • Start by mixing the food coloring into the fluff. You can either do this in the fluff container or transfer the marshmallow fluff to a bowl.
  • Pour a cup of powdered sugar onto a clean surface and spoon the marshmallow fluff on top!
  • Continue to knead powdered sugar into the mixture until you achieve your desired consistency.

Powdered sugar is key to reducing the stickiness and adding firmness to your marshmallow slime!

Sugar is a sticky substance, so in general edible slimes are a bit stickier and messier then non-edible slimes. To help with the stickiness, you can coat your hands with cooking oil for easier kneading.

This no cook, edible marshmallow slime is perfect for your youngest slime fans who want to taste everything and want to get their hands right into the mixing process.

Powdered sugar is the main ingredient in most edible slime recipes. Although you can use cornstarch or a mixture of corn starch and powdered sugar, the taste will be affected. However, you can achieve a firmer substance when using cornstarch.
Continue to add powdered sugar to the mixture till stickiness is gone!
You can continue to knead and stretch, adding powdered sugar to keep from sticking. This edible fluff slime contains sugar and sugar eventually sticks!  If you play a long time  with your marshmallow slime, you will have to add more powdered sugar.
Note: A few drops of vegetable oil on the hands before kneading can also help with the stickiness!
Edible slime can sometimes resemble a stretchy play dough type of substance, but this one has a great stretch! An edible slime will never have completely the same feel as our traditional homemade slime recipes.
However, you can feel confident knowing that they are perfectly safe for kids of all ages! If you want to learn how to make slime you can eat, this one is perfect!


Continue to knead and play with your marshmallow slime, and incorporate the powdered sugar as needed.

Squish, squeeze, pull, and stretch your strawberry flavored edible slime! Once you learn how to make edible marshmallow slime recipe, experiment with other flavors or candies.

One of the best parts of our edible slime recipes in the sensory experience for the 5 senses! You can easily talk about the 5 senses as they relate to this marshmallow slime recipe.

This marshmallow slime recipe is messy and fun, but you can also taste it and smell it! Can you hear slime? You tell me!

Unlike our regular homemade slime recipes, this edible fluff slime recipe won’t last as long. Make sure to store in a covered container, and it should be good for another round of play the next day. Although you may find the texture has changed some.

  1. I was looking for an edible slime recipe that was gluten-free and dairy free due to kids allergies and this was a major hit!

    I couldn’t believe how easy it was! It turned into a sensory activity, with the kids mixing it as it became more and more firm, and a craft! I did this with a group of 6 kids, aged 6-9. It was a hit and they loved it!

    Thank you !!

  2. Awesome! So happy to hear that! We have quite a few edible recipes that would be gluten-free including starburst and jello and gummy bear I bet!
