Olive Oil Cake with Nectarines and Raspberries

Using olive oil instead of butter creates a lighter, moister cake — use a light, fruity olive oil, not a peppery, extra virgin one. Use different fruits such as plums and blueberries or apricots and strawberries if you wish. If you are eating this as a dessert, just put the cake in the oven while you are eating your main course and you can enjoy it hot, with some crème fraîche melting over it.
