Ingredients:
1/2 cup of butter, softened
1 cup sugar
1/4 tsp baking soda
1/4 tsp cream of tartar
1 egg
1/2 tsp vanilla
1 1/2 cups flour
2 tbs sugar
1 tsp ground cinnamon
Directions:
In a medium mixing bowl beat butter with an electric mixer on medium to high speed for 30 seconds. Add the 1 cup sugar, baking soda, and cream of tartar. Beat until combined, scraping sides of bowl occasionally. Beat in egg and vanilla until combined. Beat in as much of the flour as you can with the mixer. Stir in any remaining flour. Cover and chill dough about 1 hour or until easy to handle.Combine the 2 tablespoons sugar and the cinnamon. Shape dough into 1-inch balls. Roll balls in sugar-cinnamon mixture to coat. Place 2 inches apart on an ungreased cookie sheet. Bake in a 350 degree oven for about 9 minutes or until edges are golden. Transfer to a wire rack and let cool.
