This recipe is for a very elegant and tender butter cookie that just melts in your mouth. Half of the dough yields a sugared butter cookie, while the other half is unsugared and topped with a pecan half. This recipe can be easily halved for a smaller yield, but believe me, the cookies disappear quickly. You won't regret making an entire batch because no one can stop eating them. The recipe looks more complicated than it really is. Just be sure not to slice the cookies too thickly.
