Cream the butter until light and fluffy.
Add the sugar all at once and continue to cream until the sugar is mostly dissolved and the mixture is light and smooth.
Add all the flour and continue to mix until the flour is absorbed into the dough.
Portion the dough on to a parchment lined cookie sheet and bake for 10-12 minutes at 350 degrees, or just until the edges are lightly browned.
Cool them on the cookie sheet for 5 minutes then move to a cooling rack to finish cooling.
