Preheat your oven to 180ºC /350ºF. Grease or line a 20 x 20 (approx.) casserole or baking dish.
Grate the carrots, 5 seconds, speed 4. Add to the dish. Now grate the apple, 3 seconds, speed 4.
Add the oats, currants/raisins into your baking dish and mix to roughly combine.
Without rinsing the Thermomix bowl, melt the butter, 1 min, 90, speed 4. Add the milk, eggs, sweetener, cinnamon and vanilla. Mix 30 seconds, speed 5 until well combined.
Pour over the oats/ carrot mix and top with the sugar (and optional pumpkin seeds, walnuts or pecan nuts).
Place in the oven for around 25-30 minutes or until it is set (just firm in the middle).
Rinse the Thermo bowl. Add the spiced yoghurt ingredients and blend, 20 seconds, speed 3.
When the oatmeal is cooked, enjoy immediately (with the spiced yoghurt) or cool and slice into portions to store.
