I got the recipe from Playdough to Plato (click to see the full page). I typically make half the recipe and it works well as a size for one kiddo to use (I'm also making 6 different colors at the same time so it saves me time/ingredients too).
Ingredients:
- 3 cups of flour (You can substitute with gluten free flour if you’d like.)
- 3/4 cups of salt
- 6 tablespoons cream of tartar
- 3 tablespoons of vegetable oil
- 3 cups of water
- Gel food coloring (The gel variety is a little pricier but the colors come out brighter.)
- wax paper (for cooling down)
Directions:
- Mix flour, salt, and cream of tartar in a medium/large pot.
- Add water and oil until the clumps are gone.
- Add food coloring.
- Put on stove on medium heat.
- Continuously stir until it becomes a mound of playdough.
- Remove from pot and put on wax paper.
- Let cool until you can handle it.
- Knead the dough until all the color is mixed in.
- Let sit for up to 30 minutes (or it will dry out).
- Store in an air-tight container.
I typically replace it every 3 months or so.
