# Steps:
01 - Peel the bananas and slice them into thin coins.
02 - Place banana slices in a single layer on a parchment-lined baking sheet and freeze until solid, at least 2 hours.
03 - Transfer frozen banana slices to a high-powered blender or food processor. Add milk and blend until smooth and creamy, scraping the sides as needed.
04 - Serve immediately as soft-serve, or freeze in a container for 1 hour to achieve a firmer texture before scooping.
