Preheat oven to 170ºC. Butter a shallow pie dish or baking dish and set aside.
Place 200g sugar, zest and cinnamon stick into the Thermomix bowl and mill 10 sec/speed 10.
Add vanilla, yoghurt and flour and beat 10 sec/speed 8. Scrape down sides of bowl.
Add melted butter through hole in lid, whilst blade is turning, 10 sec/speed 4. Rest batter for about 30 minutes before proceeding.
Pour batter into prepared pie dish.
Gently place fruit on top of batter. Sprinkle generously with more raw sugar.
Cook for approximately 30 minutes then turn heat down to 150°C.
Cook a further 15 minutes or until the wobble has gone.
This will sink once you take it out of the oven, but that is perfect as that is how you will see the beautiful fruit on top. You could dust with icing sugar if you wished.
