For the almond cake, beat egg yolks with salt and sugar until foamy.
Add cinnamon, vanilla sugar, lemon zest, almonds and baking powder. Beat egg whites with a little lemon juice until stiff and fold in.
Pour into a 26 cm baking pan and bake the almond cake in the preheated oven at 175 degrees for 55 minutes.
Preparation Tip:
Mix the baking powder with almonds when preparing the almond cake, never add directly to liquid. Instead of almonds, you can also use hazelnuts, so that it becomes a hazelnut cake.
