These are an easy sugar cookie to make because they require no refrigeration of the dough before rolling it out. Updated 11/2009 - after reading some of the reviews that said the dough was crumbly, I updated the ingredients to state that the unsalted butter should be softened to room temperature. I am hoping that solves the crumbly dough problem. I've never experienced that and I am thinking that is because I soften the butter before mixing. Hope that helps everyone.
