Cinnamon Sugar: 2 tablespoons granulated sugar plus 2 teaspoons cinnamon
Instructions
Preheat oven to 400 degrees F. Line cookie sheets with parchment.
Stir together flour, cream of tartar, baking soda and salt.
In a mixing bowl, combine the softened butter, sugar, vanilla and egg. Stir by hand or using medium speed of a mixer. The goal is to just stir until blended and not to whip.
Add the dry ingredients and stir to make a soft dough.
Using a medium cookie scoop, scoop up rounds of dough. You should get about 15 using a medium cookie scoop. At this point you can chill the dough balls until ready to bake or bake right away.
Before baking, mix together the cinnamon and sugar. Roll dough balls in cinnamon sugar.
Place on cookie sheets and bake at 400 degrees for 9-11 minutes or until the edges are brown.
