How to cook
Sift the flour with the baking powder and add the sugar, cocoa, baking soda and salt to them. To them, add the eggs that have been beaten lightly with the remaining wet ingredients - coffee, milk or buttermilk (yoghurt milk + milk), oil.
Stir with a whisk until everything is homogenized, and finally flavor with vanilla. Pour the mixture into a lightly greased and floured oven dish and put it to bake for 30-35 minutes at 356°F (180 °C) or until the cake is ready. Remove it from the oven and allow to cool slightly for 5-10 minutes.
With a fork, riddle the surface of the black ash cake and pour the glaze on evenly. Cut it into pieces and serve.
