I like the kinds that are borderline melted chocolate sundaes. >=] Whipped cream, marshmallows I can live without really, but definitely little chunks of chocolate inside them and perhaps hot chocolate sauce on the cream too. And maybe some kind of blob of melted ice cream dunked into it beforehand. Seriously I want it to be as rich and heavenly as possible. xD The ones from restaurants and cafes are always so much better than anything I have at home.
