Recipe from a church cookbook

Ingredients:

2 sticks of butter
1 1/2 cup sugar
2 eggs
2 3/4 cup flour
2 tsp. cream of tartar
1 tsp. baking soda
1/4 tsp. salt
cinnamon-sugar mixture

Directions:

Mix the butter, sugar, and eggs thoroughly. Mix the flour, cream of tartar, baking soda, and salt and then stir into the first mixture. Roll the dough into balls and roll them in the cinnamon-sugar mixture. Place them on an ungreased cookie sheet and bake from 8-10 minutes at 400 degrees. The cookies will puff up at first, then flatten out. Enjoy the cookies!
