I am always unsure what to call these, but they are so buttery that you can take one bite and they will dissolve in your mouth instantly. Some call these Mexican Wedding Cookies, Russian Tea Cakes, or Danish Butter Cookies. But, regardless of the name and their origins, my mother always makes these for Christmas and each year they waft our tiny brick house with butter and particles of powder sugar. They are absolutely worth fighting over especially when she started adding mini chocolate chips to them. We are true chocolate people here and just a few more hours when the rest of the family arrives they will be gone.
