The butter and carbs will make you fat.
There are a few posts telling people that certain food items they were asking about are unhealthy; there was another with the same name on the parents board - I think it's the same person.
They do have fat and sugar in them, but I've tried making them with less fat and they fall apart so I'm not sure what the answer is to trying to make them healthier. However, they do provide more fibre and things than the average biscuit so that can't be too bad.
Thanks for that PP, it looks like a good one. I have googled until I am blue in the face and just got fed up so thought I would try here incase anyone had a tried and true.
They go by various names depending where people are from. There are a few cook sites that I check for recipes but I've found that if you type in 'cereal bars' you get loads of recipes by people who think that chucking half a packet of Cheerios into a pan with melted butter and syrup makes for a healthy snack

So you have to type things like 'apple and oat bars' and 'apricot nut bars' and things to get what you're looking for.
