The night before, freeze the ice-cream-maker bowl at the coldest setting, standing flat and upright, for a full night.
Blend the chosen creamy base, filtered water, raw honey, cinnamon, and optional vanilla for about 10 seconds, until smooth with the cinnamon evenly suspended.
Pour into the fully frozen bowl and churn according to the machine directions until thick soft folds form and hold briefly around the paddle.
Serve immediately for soft ice cream, or transfer to a covered glass container and freeze longer for firmer scoops.
