That's reminded me of a favourite of mine. My kids made this when they were very small.
Chocolate Crispies
All you need is a large bowl of cereal, cornflakes, rice crispies or similar, and a slab of chocolate (I like plain but milk chocolate works too).
Mum or dad's job is to melt the chocolate, either in a pyrex bowl over a pan of simmering, boiled water, or in a microwave oven (careful it doesn't burn in a microwave). Once it's melted and runny pour the chocolate over the cereal and mix it in well. If it's too sloppy you can add a bit more cereal but make sure you combine it well.
Spoon the mixture into baking cases and leave to go cold.
My children also always made a jam tart from lumps of grey pastry (left over when I baked - and rolled, dropped on the floor, stretched, knotted and generally mishandled) that had to be cooked "for daddy".
Daddy, brave man that he was, always ate it too.
