How to make
Mix the ingredients for the cake sequentially and pour the mixture into a greased and floured oven dish.
Bake until dry on the inside (check with a toothpick) in a moderate oven, preheated to about 360°F (180 °C). Once the cake cools, cut it into squares, and smear them with the hot glaze prepared ahead of time.
For glaze, heat the water with the butter, sugar and stir with the cocoa.
Garnish with chopped walnuts and coconut flakes.
