Usually this includes a lot of additional eggs, sugar and butter but no flour - which makes it good as well but somewhat richer. I changed the recipe as i could not be bothered to whip the egg whites and care for the batter to cool down in order to add the yolks. So i went for a little four instead and gave it a try. What a treat! I love it! It is just too easy to be good :-) Enjoy with vanilla icecream. Note: You can use any chocolate you like but i recomend good quality chocolate with at leat 60% cacao.
