Sugar Cookies

Preheat oven to 350ºF.

Whisk flour, baking soda, salt and cream of tartar.

Using mixer, cream butter with 1 cup sugar until light and fluffy. Turn mixer to low and add eggs one at a time and mix just until incorporated. Add vanilla and mix just until blended. Stir in flour mixture in three parts, scraping down the bowl and beaters.

Cover and refrigerate dough for 1–2 hours.

Roll the dough in 1-inch balls. Roll balls in remaining sugar and place on parchment-covered baking sheets. Gently press the balls down with the palm of your hand until it is about 1/2 inch thick.

Bake 10–12 minutes or until the edges are just starting to brown and centers are set. Cool on cookie cooling racks.
