First, put the peanuts into the bamix® processor and chop them until peanut butter is produced. Then, mix the peanut butter, cubed butter, egg and milk with the bamix® multi-purpose blade. Add flour, sugar, baking powder, vanilla powder, cinnamon and salt. Mix everything into a smooth short pastry using the bamix® multi-purpose blade. Wrap in cling film and leave to cool for approx. 1 hour. Preheat the oven to 160 °C top/bottom heat and line the baking tray with baking paper. Lightly dust the work surface and rolling pin with flour. Use a round biscuit cutter to cut out small circles from the dough that has been rolled out to a thickness of about 4 to 5 mm and carefully place them on the baking tray with the baking paper. Bake the reindeer biscuits in the preheated oven on the middle rack for approx. 8 to 10 minutes, depending on the thickness and diameter. Leave to cool on the baking tray first, then let them cool completely on a cooling rack.
