I always read recipes that claim “easy” and then look through their 89 ingredients and 401 steps before humming the “Liar, liar, pants on fire” tune in my brain. In scouring for cookies that my littles could help with, I found a gift from Pinterest! These Sugar Cookies from Inspired Dreamer. They really are simple, they really do have a limited amount of ingredients as far as baking goes, (Full disclosure: Cream of Tarter is included, and I did have to purchase that), and they DO involve sprinkles. Which is an absolute bonus for your tiniest bakers.
Enjoy!!
