Homemade PlayDough

You need:

  • 2 cups plain flour (all purpose)
  • 2 tablespoons vegetable oil
  • 1/2 cup salt
  • 2 tablespoons cream of tartar
  • 1.5 cups boiling water (adding more in increments if needed)
  • food coloring (optional)
  • few drops glycerin


  • Mix the flour, salt, cream of tartar and oil in a large mixing bowl
  • Add the boiling water
  • Stir continuously until it becomes a sticky, combined dough
  • Add the food coloring and glycerin
  • Allow it to cool down then take it out of the bowl and knead it vigorously for a couple of minutes until all of the stickiness has gone. * This is the most important part of the process, so keep at it until it’s the perfect consistency!*
  • (If it remains a little sticky then add a touch more flour until just right)
