These buttery shortbreads are simply melt in your mouth perfection. So full of flavor and yet so easy to make, they are sure to become one of your favorites. The addition of the pecans really takes these cookies up a notch over the traditional shortbread. The pecans provide a rich nutty flavor and additional texture to really round this cookie out. Finish them with a sprinkle of powdered sugar for a little extra sweetness and an eye catching look.
