Place the banana and half the yoghurt in a food processor and process until smooth. Transfer to a large bowl.
Place half the raspberries and the remaining yoghurt in a clean food processor and process until smooth. Add to the banana mixture in the bowl. Use a large metal spoon to gently fold the raspberry and banana mixture to marble.
Pour the yoghurt mixture into a 6-cup (1.5L), 10cm x 20cm (base measurement) loaf pan. Cover with plastic wrap and freeze for 8 hours or overnight until firm.
Serve frozen yoghurt with the remaining raspberries.
