For the chocolate banana cake, grease a ring mold with butter and dust with flour. Preheat the oven to 160 °C.
Mix flour with baking powder and grated chocolate. Separate the eggs. Beat the yolks with salt and vanilla sugar until foamy.
Mash the bananas with a fork and mix with 180 g granulated sugar. Slightly whip the whipped cream with a mixer and stir in the banana mixture.
Stir the banana mixture into the yolk mixture. Beat the egg whites with the 80 g granulated sugar until stiff and fold in.
Sift the flour and chocolate mixture into the yolk mixture and gently fold in. Pour into the pan and smooth down. Bake the cake for 45 – 50 minutes.
Let the chocolate banana cake cool, spread with apricot jam and cover with chocolate icing.
