Every family has a favorite sugar cookie recipe. We had one that we used for years and it was great, but I wanted one that rivaled the delicious sugar cookies that we get at a local bakery in Yuba City. Soft, nicely shaped, cooked through and not brown or crispy on the edges.
In a large mixing bowl combine butter, shortening and sugar. Beat until fluffy. Turn mixer down and add egg, vanilla and almond extract. Add baking powder. Sift in and flour and cornstarch until mixed thoroughly (1-2 minutes).
