How to make
Dissolve the baking soda in the yoghurt. Beat the eggs with the sugar, add the yoghurt and gradually add all other products for the layer. Pour the mixture into a greased and floured tray and put to bake in the warm oven at 360°F (180 °C) for about 25 minutes.
To prepare the glaze, pour the powdered sugar and butter in a pan on the stove and stir until you get a caramel liquid. Then add the cocoa while stirring and, if necessary, dilute with a little hot water.
Allow the finished cake to cool and cut it into squares, then top with the glaze. Optionally, sprinkle coconut flakes or roll each square in them.
