In a small bowl combine 1/4 cup sugar and 2 tsp cinnamon. Mix this well, this is what you will roll your cookie dough balls in prior to baking.
In a large bowl add the flour, baking soda, salt and cream of tartar. Whisk this together and set aside.
In your stand mixer add the shortening or butter (room temperature) and sugar and mix till light and fluffy. Add the eggs and the vanilla and mix. Add the flour mixture slowly and continue to mix until combined.
Roll the dough in balls and cover each with the cinnamon sugar mixture. Place the dough balls on the prepared baking sheet that has been lined with parchment paper. Bake at 375 degrees. Bake the cookies until light brown on the edges about 10 minutes. This will depend on how large you have made the dough balls. Remove from oven allow to stand on the cookie sheet for a little bit then remove to the cooling rack. Enjoy
