Let me tell you a secret

Water 1/2 cup
Butter 1/2 cup
Sugar 1/2 cup
cocoa 1/2 cup

Fold in:

Sifted flour 1 cup
Salt 1/2 tsp
Bicarb soda 1/2 tsp
Baking powder 1/2 tsp

With:

Egg 1 beaten
Sour cream 3/4 cup
Vanilla 1 tsp

Then it is just a matter of 180C for 23'.

Let them cool and eat one hot, burning your pathetic human mouth.

While you are crying like a child, mix cream cheese, vanilla and icing sugar together.

Put that on top and eat the hell out of it.
