1 c butter, softened

     1 1/3 c sugar

     2 eggs

     1 tsp vanilla

     3 c flour

     1 tsp baking soda

     1 tsp cream of tartar

     1/4 tsp salt

     2 tsp cinnamon

     3 tbsp sugar

Preheat oven to 375 degrees.  Lightly grease 4 cookie sheets.  In a large bowl, beat butter and 1 1/3 c sugar until light and fluffy.  Beat in eggs and vanilla.  In a small bowl, stir together flour, baking soda, cream of tartar, and salt.  Gradually add to butter mixture, blending thoroughly.  In a small bowl, combine cinnamon with 3 tbsp sugar.  Roll dough into 1" balls (may also use a #50 disher) and then roll in cinnamon-sugar until completely coated.  Place on baking sheets (16 cookies will fit on a sheet) and bake for 12 minutes.  Let cool for 1 minute before transferring cookies to a cooling rack to cool completely.  Makes about 4 dozen.
