Melt the chocolate and the butter seperately, then add them together with the 4 eggs, one after the other, the flour and finally the sugar.
mix with a mixer until the paste is light (and add the cocoa powder).
Once you are satisfied with your paste, put it in the mould wich is butterd, and put it in the oven, at 150 C, for approximately 45 min.
When you start to smell the cake, it means it's nearly ready, so take a knife and point it in the cake and when you take it off and there is no mark on it, it means the cake is ready.
I suggest to surve it once it has cooled down.
