edible chocolate slime ingredients


STEP 1: Add marshmallows to a microwave safe bowl and microwave for 30-sec intervals to melt. You don’t want to overheat them as they will burn! This should take about a minute.

Caution, marshmallows will be hot!

Remove the bowl carefully from microwave using potholders as needed. Stir carefully to evenly distribute heat. Heat again if needed. A bag of marshmallows should take about a minute all together, but heating in increments will make sure they don’t burn.

Have you ever noticed what happens to marshmallows in the microwave? It’s science, and you can read more about it here when we had some STEM fun with peeps.

STEP 2: Next, add the instant chocolate pudding mix to the marshmallows and stir!

This step will also help the mixture cool down and give it an incredible chocolate flavor.

It’s time to get a bit messy!
adding powder sugar to edible chocolate slime mixture
Powdered sugar is a key 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 the stickiness is gone!

You can continue to knead and stretch, adding powdered sugar to keep from sticking. This edible chocolate slime contains sugar and sugar eventually sticks!  If you play a long time with your chocolate slime, you will have to add more powdered sugar for fun play.
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! 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!

Yay, it tastes just like a s’mores! Grab some graham crackers…
