Combine banana, vanilla, nut milk or water, and cacao if using, in a food processor or powerful blender with a tamper, until smooth and creamy like ice cream. Scrape the sides the food processor blender bowl so that all the banana is puréed.
When the mixture reaches the consistency of soft-serve ice cream, scoop into serving dishes and sprinkle, if you like, with coconut, nuts, or a bit more cacao powder.
Variation: Make a sundae with the addition of a drizzle of maple syrup or chocolate syrup. (Cè Organics makes a delicious one with fair trade ingredients.) Or drizzle with a nice brandy for a sophisticated grown-up dessert.
