There are so many things to do when you have kids at home that spending hours planning activities is just not feasible. So having a few activities in your repertoire that require little to no prep time is a must.

This homemade silly putty only takes a few minutes to make, and because it is made from just two edible ingredients, it is safe for little ones who still like to put everything in their mouths.

It is also no-cook and gluten-free, and is a fantastic alternative to glue-based slime for kids who are still too young to play with it. Keep this one on hand for the next time your child is looking for something fun to do!

How to Make Edible Yogurt Silly Putty

Required Ingredients

Here’s what you’ll need to make a batch of non-toxic silly putty for your kids using only 2 ingredients:

• Plain or flavoured yogurt
• Food colouring
• Cornstarch (also called “corn flour” in Australia and the U.K.)

While this silly putty is taste-safe and made from edible ingredients, it doesn’t taste very good, even if you use flavoured yogurt. (We only had vanilla in the fridge.) I also wouldn’t recommend letting your child eat large quantities of it because eating too much cornstarch could give them upset stomachs.

But I love knowing that if they do decide to take a few nibbles, there’s nothing to worry about!

Step-by-Step Instructions

1. Add Food Colouring to Yogurt

Start by placing ¾ cup (6 oz) of yogurt in a bowl and adding a few drops of food colouring. The colour will dull a bit after you add the cornstarch, so make sure you add a few extra drops to ensure that the colour stays nice and vibrant.

2. Add Cornstarch

Mix in 1 cup of cornstarch, adding a bit at a time and stirring until smooth.

Keep stirring until all the cornstarch has been mixed in and the dough feels smooth.

3. Knead Silly Putty

Grab the ball of yogurt dough and knead it a few times with your hands until it no longer feels sticky. If it continues to feel sticky, add a bit more cornstarch and knead it into the dough; if it feels too dry, add a bit more yogurt.

Once you’re satisfied with the consistency of the silly putty, it’s time to play! Give it to your child and allow them to explore. (Didn’t I tell you this would be easy?)

This yogurt silly putty actually has a really unique texture that I absolutely loved. At first I felt that it was behaving more like play dough, but as we played with it, it became really stretchy and started to behave like slime.

Thankfully, unlike slime, this silly putty doesn’t contain any borax or other toxic ingredients that would make it unsafe for babies and toddlers. This makes it a great alternative if your older kids are playing with “big kid” slime and your younger kids want to participate!

Note: We were able to store ours in the fridge for a couple days and reuse it a few times before we threw it in the compost, but of course, your ability to do this will depend on how long it stays out of the fridge and how filthy it gets during play.
