10. Gently sprinkle over the crumble mixture and cook for a further 10-15 minutes.
11. To test if the cake is cooked through, poke a skewer into the middle and it should come out clean.
12. Allow to cool for an hour before serving. Serve with extra yogurt on the side.

Note: This cake is best eaten on the day of baking so the crumble topping is crisp.
