Know its deffinately not SW friendly but if you add a grated courgette to a chocolate cake you will have the most moist chocolate cake you have ever tasted and it will keep for a several days too, cos chocolate cake does have a habit of being dry and a bit yuk, but with a courgette added, this is to die for. Oh, and no it doesn't taste of courgette, you don't taste it at all, just yummy....... rich ........moist...... chocolate cake. Stop it girl, chocolate cakes are bad thoughts, smacked hands.
