Zimtsterne (cinnamon stars) are maybe THE traditional German Christmas cookies. Everyone loves these little treats. But many don't like to make them, because the sticky dough can be a bit tricky while cutting the stars. But if you take the time to make them, it is more than worthwhile all the work. They are heavenly. If you have tasted the first you can't stop eating them. And christmas without Zimtsterne? NEVER! They are a must.
