The Recipe is flexible and I can add this and that to keep the bars from getting boring.
1 large tin of condensed milk.
Rolled oats.
Warm the condensed milk and add the rolled oats and mix well. Shredded coconut, chopped nuts, whole peanuts, dried fruits of any kind and chocolate drops are all good to add. Peanut butter or chocolate spread can be substituted for some of the condensed milk. I haven't tried spices but I suspect cinnamon and apple would be good.
When your chosen ingredient are mixed well together, press the mix into a lined tray. Push down well with the back of a spoon. Bake in a warm oven 130c for 1hr. When cooked mark into bars while still warm. Store in a airtight tin.
