Turn the oven on 180 degrees. Grease a baking tin with the butter and a little bit of flour. Mix the sugar, eggs, hot water and cooking oil.
Then, add the flour, the baking powder and the powder chocolate to the previous mass and beat well.
Throw the mass to a baking tin and bake for 50 minutes.
Unmold the cake while still hot and let it rest for a while.
Let’s do the chocolate frosting. Boil the cream and mix the chocolate still on the fire. Beat until it gets thick.
With the help of a spatula, spread the chocolate frosting over the cake and, after a few minutes, spread the grated coconut.
