This is a recipe of a very low in calories and fat sponge cake. I will have approximately 240 KCal/100g or 120 KCal per decent portion. It is an adaptation of the recipe I found at bbc good food web site. The cake does not have any fat at all and uses a light sweetener (red canderel) instead of sugar. It also has very little flour. It is very easy to make, about 20 minutes relaxed preparation and 20 to 30 minutes baking.
