Finely grind whole almonds. Mix with flour, baking powder, cocoa and gingerbread spice. Add fat in pieces, egg and sweetener and knead with the dough hooks of the hand mixer. Then briefly knead with your hands until smooth. Cover and chill for approx. 30 minutes.
Roll out the dough on a little flour to a square (approx. 30 x 30 cm) about 4 mm thick. Using a dough wheel, roll out 30 rectangular cookies of the same size (approx. 5 x 6 cm)
Sprinkle almond flakes on the spice biscuits and press them on. Place the cookies on a baking tray lined with baking paper
Bake the cookies in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C / gas: level 3) for 12-15 minutes. Let them cool down
