1 1/2 c. sugar
1 c. butter
3 egg yolks
Pinch of salt
1 c. sour cream
1 tsp. baking soda
1 tsp. vanilla
flour - to be added gradually

Mix ingredients - add enough flour so dough can be rolled out on floured surface. Do not make dough too stiff or cookie will be dry. Roll out 1/8 inch thick and cut into desired shapes.

Bake at 325 degrees until cookies are very light brown but still moist. Frost and decorate as desired. Makes 5-6 dozen cakes.
