Chop the ginger finely. Mix flour and baking powder in a bowl. Add fat, vanillin sugar, maple syrup, eggs and milk and mix with the whisk of the hand mixer to a smooth dough. Finally stir in muesli and ginger. Using a tablespoon, place 6 piles of dough on each of 2 baking trays lined with baking paper and press them flat a little. Bake the trays one after the other on the middle shelf in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 15-20 minutes. Remove cookies from the paper and let them cool down on a cake rack
