1/2 cup butter or margarine, softened
1 cup sugar
1 egg
1 teaspoon vanilla
1 1/2 cups flour
1/2 teaspoon baking soda
1/4 teaspoon cream of tartar
2 tablespoons sugar
1/2 teaspoon cinnamon
In a mixing bowl, beat butter and sugar together with a mixer. Add the egg and vanilla and beat well. Add the flour, baking soda and cream of tartar. Mix well to combine. Wrap the dough up in plastic wrap and chill for at least 1 hour.
Combine the sugar and cinnamon.
Preheat oven to 375ºF. Roll the cookie dough into small 3/4 inch balls. Roll each ball of dough well in the cinnamon sugar mixture. Place on an ungreased baking sheet 2 inches apart.
Bake for 10-11 minutes, or until the edges just begin to brown. Remove the cookies from the baking sheet to a cooling rack to cool completely.
Makes about 45 cookies.
