Beat the eggs and sugar until frothy and then stir in the oil, water, baking powder, flour and cocoa. Place the dough on a greased baking sheet and bake at 175 ° C for about 20-25 minutes.
Spread the red groats evenly on the cooled cake. Whip the cream with the cream stabilizer and vanilla sugar until stiff and distribute it on the cake as well. Now put the chocolate and the cold milk in a container, heat them together and melt the chocolate. Stir well so that no lumps are formed!
Carefully brush the cake with the chocolate-milk mixture, sprinkle with desiccated coconut, let cool and then enjoy!
