I do enjoy a scan bran chocolate cake:
5 scan bran softened in water,
2 tablespoons cocoa powder,
2 tablespoons golden syrup
artificial sweetener to taste
3 eggs
mix it all together and put in microwave for 8 mins,
I like it best warm with some berries and FF fromage frais.
I do genuinly enjoy it rather than just eating it for the sake of having cake.
