How to make
Melt the butter, add the cocoa, sugar, water. Boil 3-4 min. Set aside 1 cup of this mixture. To the rest, add the eggs, flour and baking powder.
Bake 5-10 min. in a preheated 360°F (180 °C) oven.
Once baked, take the oven dish out, put the cake onto a wooden board. Stick a knife between the cake and board, to heat it up, then use it to cut the cake into squares while still hot.
Pour on the rest of the cooled mixture. Leave it to cool completely.
