Put butter, sugar and vanilla sugar in a bowl and stir. Then add the eggs and the flour mixed with baking powder and knead everything.
Remove small pieces from the dough, form small tears from them and place on the baking sheet. Bake the hedgehog biscuits at 200 degrees for about 10 minutes.
When they have cooled down, dip the thick half of the hedgehog in the chocolate and sprinkle with chocolate sprinkles. Draw on the eyes and muzzle with the tip of a toothpick.
