I like them either with a sourish jam like redcurrant jelly or cornel cherry jam or with a mix of plain yoghurt and fresh berries (strawberries, blackberries, blueberries, red currants, black currants, gooseberries - whatever is at hand.
See picture below)
My mom eats them with apple purée and/or with heaps of sugar. She insists that "pancakes must crunch" [with sugar], else they don't count as pancakes. Stands to hope she'll never turn diabetic.
Edit: totally forgot: German pancakes differ from your American ones. Ours are larger and very thin and soft. Much like French crepes or Mexican tortillas, only fluffier and softer than either.
