Place the vanilla beans on a lined baking tray and into a cold oven set to 200°C for 15 minutes. Remove and cool before proceeding.
Place all the ingredients but the coconut sugar into the Thermomix bowl and blend 1 min/speed 10. Scrape down sides of bowl and repeat.
TIP: Put a piece of baking paper or a paper towel underneath the MC while blending to prevent the chai from filling the kitchen!
Add the coconut sugar and stir through. Keep in a container in the pantry.
