Cut the marzipan into fine cubes and chop the nuts very finely. Then put all the ingredients (marzipan, nuts, rum, raisins and cranberries) together in a bowl.
Pour the mixture into the apple and cover it with the butter flakes. Bake the apple in a preheated oven at 175 degrees for about 20-30 minutes. (Depending on the size of the apple).
Please serve the apple with vanilla sauce or vanilla ice cream.
