You will need:
2 3/4 cups flour
2 teaspoons cream of tartar
1 teaspoon baking soda
1/4 teaspoon salt
16 tablespoons butter, at room temperature
1 1/2 cups sugar
2 large eggs
1/2 cup cinnamon-sugar mixture (use whatever ratio cinnamon to sugar you prefer)
In a small bowl, mix together flour, cream of tartar, baking soda, and salt.
In a separate bowl, combine butter and sugar with an electric mixer until light and fluffy. Add the eggs, and beat to combine. Add the dry ingredients slowly, taking care to scrape the sides of the mixing bowl as you go.
Chill the dough for at least one hour.
Once ready to bake the cookies, preheat your oven to 400 degrees. Use a spoon to form balls of the dough and roll in cinnamon-sugar mixture. Place cookies about two inches apart on a baking sheet. Bake for 8-10 minutes.
