my mother in law is 60 next week and fool that I am i've offered to make the cake. I've got an idea for the decoration but although usually good at baking whenever i make a birthday cake it never seems to rise goes burnt on the top and isn't level. Any tips please and how to ice it, ie marzipan and then icing and what icing to use. The decoration is going to be figures of a woman painting, gardening, bricklaying etc as my mil is a jack of all trades and we think this would make it quite personal to her. Any help please
