This is modified from an Alton Brown recipe on the Banana episode of Good Eats. I replaced the cream with coconut milk and the corn syrup with agave nectar to make it vegan and healthier. I also added the optional carob chips and coconut flakes, which my friends agreed really worked well with the banana flavor. Despite its healthiness, this recipe is still luxuriously thick, "creamy," and rich. Instead of chilling the mixture before putting it in the ice cream maker, you can use frozen bananas. Be sure to use regular (not light) coconut milk. Cooking time is freezing time in ice cream maker.
