Add eggs one at a time, beating well after each addition. Add vanilla and beat until light and fluffy.

In a separate bowl, mix and sift flour, salt, baking powder and baking soda.

Add dry ingredients alternately with sour cream; beginning and ending with dry ingredients.

Drop by teaspoons or tablespoons depending on the size cookie you want. Sprinkle cinnamon-sugar mixture over the tops of the cookies. Bake for 8 to 10 minutes.
