Finely chop the candied lemon peel. Beat the eggs with the whisk of the hand mixer until frothy. Add sugar and vanillin sugar and continue stirring until a light creamy mixture is obtained.
Add spices and stir in. Stir the candied lemon peel, nuts and baking powder into the dough. Spread the dough on wafers, place on a baking tray lined with baking paper and bake in a preheated oven (electric range: 200 °C/ gas: level 3) for 15-20 minutes.
Remove from the oven and let it cool on a cake rack. In the meantime, stir icing sugar and about 2 tablespoons of water until smooth. Coat the Elisenlebkuchen with the icing.
