Combine all ingredients in a saucepan and whisk to blend.
Place the saucepan over medium heat and cook for 5 to 7 minutes, stirring constantly.
When the dough comes together like a ball, transfer to a cutting board lined with baking paper.
When the dough is cool enough to touch, knead until smooth. This should take about 2 minutes.
Repeat for each colour of playdough you want.
Store in an airtight container in the fridge for up to 2 months.
