Sugar Cookies

Todd really likes these cookies!  They are thin and delicious!  You make the dough a day ahead of time!

2 sticks butter
1 cup sugar
1 cup brown sugar
2 1/2 cups sifted all-purpose flour
1 egg
2 tsp baking soda
2 tsp cream of tartar
2 tsp vanilla

Using an electric mixer, mix all ingredients in a large bowl (these cookies turn out so much better if all ingredients are room temperature).  Place dough in refrigerator overnight or for several hours. 

Pinch dough to form medium size balls (about 1/2-1 inch).  Roll balls in granulated sugar and place on a cookie sheet.  Bake for 10-15 minutes at 350.  Cool on wire racks.
