This is a recipe from Pam Pace, a teacher who taught in the classroom next to me for many years, until she passed away. Hope, my daughter-in-law, asked me to make them for her birthday dinner today. She only likes pink icing. You can see the fingerprint in the first one. Someone couldn't wait to try them.
3 1/4 c. flour
1/2 c. butter
1 c. sugar
1 t. soda
1/2 t. salt
1 t. vanilla
3/4 to 1 c. commercial sour cream (I triple the batch and use 16 oz of sour cream.)
Mix like you would regular cookies. Chill for 1/2 to 1 hour. Roll out with powdered sugar instead of flour. (I always roll sugar cookies out with powdered sugar and the dough never gets stiff.) Bake at 350° for 10 minutes. Cool and ice with your favorite icing.
