The best of both worlds where snickerdoodle cookies and butterfinger candy collide.
Roll the dough into balls about the size of a whole walnut and set them on to a large plate. It's helpful to roll all of the cookie dough balls at once (and set them on a large plate) before coating each of them with the sugar mixture. Otherwise, your hands will have sugar on them which will stick to the dough balls when rolling them. Set aside for a moment.
