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