Preheat the oven to 170 ° C (top / bottom heat). First mix the dry ingredients and then add the eggs and liquids.
Pour the dough into a greased springform pan and bake for about 35 - 45 minutes. The cake is ready when you can put a toothpick in it and no more dough sticks to it when you pull it out.
While the cake is in the oven, the cookies must be grated by hand on a grater. It`s exhausting, but the result is good because the pieces are of different sizes.
Let the cake cool, cover with cake icing and sprinkle the biscuit crumble on the warm icing. Then decorate the cake with a doll arm or a tombstone. Outside of Halloween you could also decorate it with moles.
