I normally mess up flapjacks. They were the first thing I made in Home Economics (yes it did used to be called that in the 80s) along with fresh orange juice. But my oven in the last house used to not cook them properly, making them crumble rather than slice.
I saw this recipe on Netmums www.netmums.com (I can't do links on my ipad) under the heading Healthy Lunchboxes. My friend with her 6 week old baby came to visit today along with her parents, so they were the perfect guinea pigs.
