Sift together the dry ingredients, then mix in the butter and knead until it forms a dough.

Put the dough in the refrigerator and let it set for about an hour or so.

Take dough out of the refrigerator and roll shortbread into small ball like shapes, then press to make flat. Place onto a lightly greased baking pan and bake at 375°F for 20-25 minutes (make sure you let the cookies cool at least 10 minutes to let them set and harden before removing them).
