Sift:
1 c. light brown sugar.

Mix thoroughly with:
4 c. sifted flour

Add and work in until a smooth dough is formed:
1 lb. softened butter

Turn onto a lightly floured surface and pat to ½” thickness. (If necessary chill for easier handling) Cut into desired shapes (I usually cut into 1” squares) and transfer to cookie sheets.  Bake at 325 degrees about 25 minutes or until delicately browned.
