CHOCOLATE ITALIAN SPONGE CAKE by For the Love of Italian Cooking

An Italian chocolate sponge cake has only four ingredients: eggs, sugar, flour and cocoa powder. Vanilla can be added to enhance the chocolate flavour. The beauty of this cake is that it has no fat, no dairy, and no leavening agents. Stiffly beaten egg whites make this cake airy, soft, and spongy.

I love this because you can get your fruit serving and cure your sweet tooth all in one slice. You can use cake recipe from scratch but homemade cakes don't seem to come out as moist as cake mixes.
