Add in wet ingredients and cook over medium-low heat, stirring constantly.
Cook until the dough begins to look dry and pull away from the pot.
Allow dough to cool for 5-10 minutes, then knead. Shape into balls and add food colors.
Notes
Add glitter for snow dough and/or spices (nutmeg, cinnamon) for scent.
I prefer gel colors over liquid. The color seems more vibrant and consistent.
This play dough lasts several months if stored in an air-tight container or storage bag.
