Preheat oven to 250. Melt butter or margarine. Line cookie sheet with foil and spray with Pam.
Mix all ingredients together. Form into desired shape (ie; balls, fingers or crescents). Place onto cookie sheet and bake at 250 for 45 to 60 minutes. Roll in powdered sugar while cookies are still warm.
Note: I have actually used self-rising flour and omitted the salt and they worked fine.
