My son says he heard a really funny song somewhere in the internet, which sounded like very angry metal music with German lyrics, but the lyrics actually were a cupcake recipe. We can’t find it, does anyone know where it is?
That might be a song on the Tool album “Aenima” called “Die Eier Von Satan.” It fits what you’re describing just about to the letter. It’s track ten.
That’s the one!! The punch line “and no eggs!” nails it! 
I think it’s … that tool song. Had you fooled didn’t I? 
In case anyone doesn’t get it, “eggs” is German slang for “testicles”, much like we use “nuts”.
