For the chocolate cake, separate the eggs and whisk the yolks with the sugar until well frothy.
Melt the chocolate (if you prepare the applesauce yourself, you can also melt the chopped chocolate very well in the still hot applesauce).
Stir the cooled applesauce and the soft chocolate into the yolk mixture. Sift flour, baking powder and Ovaltine together and stir into the batter with a little rum.
Stir half of the chopped almonds into the batter as well. Beat the egg whites with a pinch of salt and gently fold them in.
Spread the batter on a baking sheet (30 x 40 cm) lined with baking paper and sprinkle with the remaining almonds.
Bake the chocolate cake in the oven preheated to 180 degrees for about 40-45 minutes.
