Here is another cake made with grated courgette – please don’t stop reading now! This one is gluten free as it is made with rice flour and ground pistachio nuts. The sponge contains cocoa powder for a rich, dark chocolate flavour and it is sandwiched together with a cocoa flavoured butter cream. The grated courgette keep the sponge moist and the ground pistachio nuts give it a slight crunch. It seems strange to make a cake with vegetables and then say you can’t tell that they are there but don’t be put off – this is a delicious cake!
