chopped nuts and marzipan for decoration (optional)
Mix the molasses, lemon juice, orange rind, oil, soya milk and fruit together thoroughly. Sift the flour, baking powder and mixed spice together and stir into the fruit mixture. Turn into a 20cm (8 in) non-stick cake tin.
Bake at 150C/300F/Gas Mark 2 for 2 hours. Cover with greaseproof paper and bake at 120C/250F/Gas Mark ½ for another hour or until a skewer inserted into the cake comes out clean and dry. Decorate with nuts, if desired, or cover with marzipan after baking.
