Celebration Cookies

This recipe for sugar cookies came from the New Era many years ago!  Probably around the mid 1980's.  It's the only one I have used since then.
1 cup butter
2 cups sugar
2 eggs
1 cup sour cream
1 tsp vanilla
1/2 tsp baking soda
4 tsp baking powder
4 1/2 cups flour
1/2 tsp salt

Cream butter and sugar.  Add eggs and beat well.  Add sour cream and vanilla.  sift dry ingredients and add to creamed mixture.  Chill.  Roll out to 1/2" thick.  Cut into desired shapes.  Place on greased cookie sheets and bake at 350 for 14-17 minutes or until lightly brown.
