Bloody hell, need! That's awful! 
Laska, did you guess I found this thread whilst stalking you after that abortive post of yours on the 5:2 thread! 
Thanks, Fluffy!
fuzzpig, I made that cake in a silicon cake former - but you could use any shallow microwavable dish. And I do have a recipe for 'Cake in a mug' on the blog. Any 8-yr-old should be able to manage the whole thing from start to finish, since the mug handle wouldn't get too hot.
Laska I have a 5:2 calorie counted version of the cake on there - plus carrot cake, parkin, trifle, frugal crepe Suzette, and more!
Talking of 5:2, someone was talking upthread about joining a slimmers club - but the 5:2 way of life (WOL) - it's not a diet - will help you lose weight, and save you money in the process!
Here are some inspirational stories, which might well..inspire you I guess!
