Soften butter (15 seconds in microwave).
Cream butter; gradually add sugar. Cream until fluffy; beat in eggs or milk and vanilla.

wrap dough in plastic wrap. Refrigerate for about one hour or until firm enough to roll.
Remove the chilled dough from the refrigerator and knead it with hand again,and on a floured surface,roll out the dough to a thickness of 1/4inch (1cm) (make sure the dough does not stick to the counter).
