First cover the cake tin with aluminum oil so the cake will get out easily. Mix the eggs until light and fluffy, then add the butter. Be sure that the butter has cooled down a little before you add it! After that, it’s time to add the vanilla, the cacao, the cinnamon and the mixed spices to the mixture. Crumble the biscuits and add these too. Now it’s time to pour the batter in the baking mould. Press the mixture a little to make sure it won’t fall apart.
Fridge for one night. Cut with a sharp knife. Yummy!
