This easy 4-Ingredient Marshmallow Playdough recipe doubles as edible playdough!
A great fun activity for kids of all ages and marshmallow lovers.
Last year I shared my marshmallow slime recipe with you, time for the playdough version now!
How To Make Homemade Marshmallow Playdough Recipe
This edible marshmallow play dough is basically a cake fondant recipe which means you can eat it. All you need to make this easy playdough recipe with marshmallows are 4 ingredients, a microwave-safe bowl, and a spatula.
- Marshmallows – white, pink, or a combination of both to light pink homemade play dough color.
- Powdered sugar – some recipes use cornstarch instead, which works but watch out. It’s not safe to eat tablespoons of cornstarch so if you are making an edible playdough recipe, use powdered sugar.
- Vegetable oil – a light color, light flavor oil is the best, like canola oil or coconut oil.
- Drops of food coloring – optional.
First, in a large microwave-safe bowl, add water to the marshmallows. If you want to change the color of the marshmallow play dough, add a few drops of food coloring now.
Microwave on high – 800-900 Watts – for 30 seconds or until the marshmallows expand and almost double in size.
Remove carefully from the microwave – the bowl is hot.
Add oil and powdered sugar and start stirring until it forms a soft paste. Now, add more powdered sugar, up to 1/2 cup, or until it forms a dough that kids can play with.
If sticky, add more powdered sugar or corn starch if you don’t intend to eat pieces of this play dough.
If too dry, add a teaspoon of lukewarm water until the texture is perfect and easy to knead and roll on parchment paper.
Marshmallow playdough tends to get stickier with time, so to avoid a mess, stick a piece of parchment paper to the playing table and give some extra powdered sugar to the kids. If the dough starts to stick, add more sugar.
Then, let the kids be creative and pretend to play any game they like. We always give the kids some of the playdough tools below:
- Rolling pin
- Plastic knife
- Cookie cutters
A fun science activity
Believe me, edible playdough recipes made of real food are the ones kids love the most.
The way marshmallows expand in the microwave is an amazing science experiment for kids. It’s visual, fun, impressive, and much more than just making playdough.
This playdough with marshmallows loses some softness after a few days. Place the playdough in airtight zip bags at room temperature for the best storage.
Frequently Asked Questions
Does this marshmallow playdough last long?
Honestly, no. It will harden fast, but kids have a blast playing with it especially watching you making the playdough!
Can I use cornstarch instead of powdered sugar?
Yes, you can use the same amount of one or the other but remember that corn starch playdough recipes are not edible.
Raw corn starch is not safe for consumption.
Why did my playdough split?
Playdough splits when you add too much sugar. Add some water to fix it and bring it back together.
Knead the dough by hand to press split pieces together and gather them into a soft playdough ball.
What to do if my dough is too wet?
Simply add more powder sugar and knead by hand between each addition until the texture is to your liking.
