If you've never had carrot cake before, you might find it odd that it centres around an apparently savoury vegetable. But in fact, carrots are the second sweetest vegetable around, after sugar beet. Add to that a thick cream-cheese-based icing, and this is an irresistible cake.
If you have no self-raising flour, you can use the same quantity of plain (all-purpose) flour, plus one extra teaspoon of baking powder. For the icing, you'll need the juice and zest of half an orange.
