Combine all the ingredients in a bowl and mix well. Keep covered for about 45 minutes to rest.. Then take out small portions with a tablespoon and shape into balls with your hands.
Place the cereal balls on a baking tray lined with baking paper and bake in a preheated oven at 180°C (fan: 180°C, gas mark 3) (approximately 350°F) for 25-30 minutes. Take the tray out and let cool the cereal balls. Serve.
