Put the oats in a food processor and blitz to a fine powder. Transfer to a food processor, then add the peanut butter, 4 tbsp coconut and the raisins and apricots. Process for 1 minute until you have a thick paste. Set aside in the fridge.
Put the crisp cereal in the food chopper and pulse until you have medium-size crumbs.
Divide and shape the chilled mixture into 18 balls. Roll a third in the crushed cereal, a third in the remaining coconut and the remaining third in the sesame seeds. Store in an airtight container.
