Pumpkin Snickerdoodle Cookies are the perfect Fall recipe with its warm, cinnamon-y, pumpkin spice-sugar coating on the outside and pumpkin flavor on the inside.
In a large mixing bowl, beat the unsalted butter, 1 cup sugar, baking soda, and cream of tartar, 1/4 tsp. pumpkin spice mix, scraping down the sides of the bowl, as needed.
