The blogger says: For the icing, I used a homemade Carob-Date Spread with Rhum and Orange extract. I just soaked the dates (three or four cups) in warm water, drained them and puréed them in the food processor, adding a bit of Carob powder (Cacao is also great !) and the extracts, to taste. Couldn't be simpler and it's good for you That spread is also wonderful on toasts, for breakfast or on muffins, or by the spoonful (shhhh !)
