How do you say 'you are so sweet' in German?
You are (so) sweet. - Du bist (so) süß.
That's so sweet of you. - Das ist so süß von dir.
It's usally translated to "Pfannkuchen" even though I can say thanks to personal experience that they are kind of diffrent in taste and preparation. So real pancake's are also called pancake's sometimes. What a 'real pancake' is is a matter of geography. The German pancake is like the French crepe in taste and texture and not as sweet as its American cousin
