Add everything (except the milk) to a blender and blitz until combined and smooth. Pour into a Creami tub, cover and transfer to the freezer for 24 hours, or until frozen through.
When ready to serve, churn on FULL, FROZEN YOGHURT in your Creami. If the frozen yoghurt is crumbly, add in 3 tbsp milk and select FULL, RE-SPIN.
