Separate eggs. Beat egg white (possibly in portions) until stiff. Mix egg yolks, sugar and vanilla sugar with the whisk of the mixer until creamy. Stir in ground almonds, 1⁄2 tsp. cinnamon, lemon and orange peel.
Fold in portions of beaten egg white. Fold in raspberries. Fill the dough into the form, smooth it down. Bake in a hot oven for 45-55 minutes. Take out and let cool down.
Roast whole almonds in a pan without fat, remove and chop. Remove the cake from the pan, dust with icing sugar and sprinkle with chopped almonds.
