Peel the bananas and split them down the centre. Place in 2 bowls, cut-sides facing upwards.
Spread the nut butter over the banana halves, place the scoops of frozen yogurt on top, add the berries and scatter over the granola.
Nut alternativesIf your child or any of their friends have a nut allergy, look out for pumpkin seed butter from health-food shops. Or make your own by whizzing toasted pumpkin seeds in a food processer for 5 mins, or until they turn to a smooth peanut butter consistency. You may have to add a drizzle of flavourless oil. Store in the fridge for a month.
