Spice up your sensory dough with this secret ingredient! Just use equal parts pumpkin puree and cornstarch and mix. For a PSL version, also add a teaspoon of pumpkin spice. You’ll definitely want to cover your table for this one as the dough is sticky, orange, and totally satisfying. And, of course, don’t allow kiddos to eat this dough (no matter how good it smells), and toss it out when you’re done playing as the pumpkin will spoil.
