Start this recipe by beating together the sugars and butter till light. Add in the eggs, one by one, followed by the flour and spice. Finally, fold in the fruits and nuts followed by the orange juice and zest. Pour half of this mixture into your prepared baking loaf tin. Roll out the marzipan the same size as the baking tin and place onto of the cake mixture. Pour the remaining cake mixture on top and even out. Bake in the oven at 160`c for approximately 2 hours, or until a skewer inserted comes out clean. Allow to cool down completely before decorating. To finish off, mix together the icing sugar with the milk and a little yellow food colouring to a stiff glace icing. Pour over the cake, allowing to drizzle slightly over the sides. Finish off by decorating the top with toasted nuts and glace cherries.
