Once you add the flour to the dough, keep the mixing to a minimum. Too much mixing will give you a tough, misshapen cookie. Add the flour all at once and then mix it for another 15 seconds or so. If it’s not mixed all the way by then, finish it by hand. If you’re using my Orange Vanilla Spice Cookie recipe, the dough should be pretty stiff. If it seems very sticky and soft, add a little more flour, a handful at a time (I’ll make a video tutorial on this process soon)
