Old-Fashioned Soft Sugar Cookies

My cousin Rica shared this recipe with me when she was living with my mom and going to Utah Valley Community College.

1/2 cup butter
1 cup sugar
1 egg
1/2 cup sour cream
3 1/4 cups flour
1 tsp baking soda
1/2 tsp salt

Cream butter, sugar, egg, vanilla and sour cream.  Sift dry ingredients together and beat into sour cream mixture.  Roll onto lightly floured board, 1/4" thick.  Cut in assorted shapes.  Bake on greased cookie sheet, 2" apart for  8-10 minutes or until lightly browned.  If desired frost cooled cookies with icing (below).  Makes about 2 1/2 dozen cookies.
