These tasty sweet treats are an adaptation of the traditional rhubarb crumble, and can be eaten warm or cold, preferably with icecream or as break time snack.

This is a fun recipe to make with kids - precision isn't essential and there's a nice combination of working with your hands, using weighing scales and handling utensils.

70g unrefined golden castor sugar
