Mmh, as far as I experienced german cakes are usually not sweet enough for american taste.
But I'd make my grandmas apple cake - that is really sweet with cinnamon and stuff - there is nothing healthy about it
so don't be afraid *grin*
The pastries are pretty sweet, and pretty darn good! When I travelled across southern Germany I was amazed by the amount of bakeries there were in the towns. And sandwich bars. Oh and those giant pretzels with melted cheese...mmmmm
