This Olive Oil and Red Grapes Cake can be the perfect dessert and tea time favourite and this one does not dissappoint, deserving to be a standard in every family recipe collection. It is the best plain cake that I have ever eaten. This simple cake can be enjoyed on it's own with a dusting of icing sugar . Recipe adapted from TV Cooking Program - French Food At Home, it's Laura Calder favourite's cake. Simple and easy to prepare.
