You might hate it, but L'Instant de Guerlain pour Homme does have chocolate cake in it, as well as other, woody accords. I owned the EDT once but now I await the EDP which should be on my doorstep soon. I've heard it's even more powerfully chocolate.
I love Aomassai 10 too, it's great. Not quite full-bottle worthy, though. I agree than an EDP should be in order.
