I make mine like it says in mikes blog and it is a case of trial and error and seeing how long they need in your specific microwave....but I really dont think I would have got through 3 months of CD without them.
Of course they are not like the double choc muffins you get in asda or tesco.......but i do find them yummy and a real treat in my CD day. I would suggest you try them again and see how you get on.
