Sensory Activity: Marshmallow Play Dough

What child wouldn’t love playing with squishy, moldable, and even edible play dough? This is a great tool for sensory exploration and fine motor development! Try using cookie cutters and other molds to make shapes out of the dough, or just make shapes with your hands!

Make Marshmallow Play Dough with the super easy recipe below!



  • 6 Large Marshmallows
  • ¼ cup Corn Starch
  • 2 tsp coconut oil
  • 12 drops Liquid Food Coloring

Add the marshmallows, corn starch and coconut oil to a microwave safe bowl. Microwave on high for 30 seconds. Then add the food coloring to the marshmallows or the oil. Don’t add it to the corn starch or you’ll have a harder time getting a consistent color when you mix it together. Stir it with a spoon to get all of the ingredients combined. When it gets too hard to stir with a spoon, you’ll need to use your hands to kneed it to finish the job.


It might be hot from the microwave, so check the temperature before giving it to the kids to kneed. If it’s too sticky and doesn’t combine, try adding another big teaspoon of cornstarch to see if that helps. If it’s still too sticky, add about 1/4 teaspoon of coconut oil, and squish it all together. Play with it on a non stick surface, such as parchment paper taped to the table or a silicone baking mat.


There you have it! Have fun and remember, this dough is edible–although it doesn’t taste as sweet as you’d think because of the marshmallows. Don’t worry if your child taste tests, they probably won’t eat much.
