I have a strong suspicion that I already wrote this recipe up somewhere, but I can't find it, so here it is again. The proportions got gradually modified over the years and the result is now much more chocolatey, so it not completely the same anyway. The "original recipe" was found in one of the blogs under livejournal umbrella; there it said that it was copied (also modified, I think) from a book.
Anyway, here it is as I make them now.
