Soft Sugar Cookies

3 1/4 cup of flour
1 tsp. soda
1/2 cup soft butter or margarine
1 cup sugar
1 egg
1 1/2 tsp. vanilla
1/2 cup sour cream

Sift together flour and soda. Combine next 4 ingredients. Beat 2 minutes. Add sour cream and half of flour mixture. Blend then beat 1 minute. Add rest of flour and stir by hand. Roll to 1/4 inch thick and cut with cookie cutters. Place on greased cookie sheet. Bake at 375 degrees  for 10 minutes.
Icing - 1 stick butter, 1 tsp vanilla, confection sugar to consistency, plus milk. I usually use a can of icing and add different food colors then spread icing on cooled cookies.
