Slice bananas in half or ½-3/4 inch rounds. Place bananas in a single layer on a baking sheet lined with parchment paper or silicone baking mat. Freeze for at least 2 hours. Transfer to a freezer-safe bag or container.
Mashed
Mash and measure desired amount, I like to freeze in ¼ or ½ cup portions. Transfer mashed bananas to freezer trays, close the lid, and freeze overnight.Once frozen solid, remove from the tray and transfer to a freezer-safe bag or container.
