Lebkuchen is pretty popular. It's a kind of spice cookie. If you want to avoid that, pflaumenkuchen is also good. It's a plum cake.
Don't take my word for it though- I've only taken a couple cooking courses! It would be much better to get information from someone living in Germany.
biscuit
No, although biscuits may be sold in a pastry shop, they are not a type of pastry. A "pastry" has to contain some pastry to be a pastry. Pastry is generally designed to be light and crumbly, whereas biscuits are not.
A palmier is a type of puff pastry made in the shape of a palm leaf and rolled in sugar.
Konditorei
You can use short pastry to make biscuits and cheese twirls. The pastry is nice and crumbly and is great with cheese also try chocolate drizzled on top .To make cheese twirls mix in cheese with the pastry then shape it and bake the biscuit will have a cheesey tang to them.
