Directions

1. Preheat the oven to 400 degrees F. Line several half sheet pans with parchment paper and set aside. Combine cinnamon and sugar in a bowl, set aside.
2. Cream together the sugar, butter, and shortening. Just until mixed. Scrape the bottom and sides of the bowl occasionally with a rubber spatula.
3. Stir in the eggs, pumpkin, flour, cream of tartar, baking soda, cinnamon, nutmeg, ginger, and salt.
4. Roll cookies into 1 1/2-inch balls and roll in cinnamon sugar mixture. Place the cookies on the parchment lined half sheet pans evenly spaced apart. (3 cookies per row with 4 rows)
5. Bake 8 to 10 minutes or until set. Let cool on a baking rack before removing from the sheet pans.
