Prep the bananas: Peel and slice bananas into coins. Spread on a parchment-lined tray and freeze for at least 2 hours, or until solid.
Set up your blender: Add frozen banana slices, milk, vanilla, and a pinch of salt to a high-speed blender or food processor.
Blend in pulses: Start on low and pulse to break up the bananas.
Scrape down the sides as needed. Blend until thick, smooth, and creamy.
Adjust texture: If it’s too thick, add a splash more milk. If it’s too soft, pop it back in the freezer for 10–15 minutes to firm slightly.
Add flavors (optional): Blend in cocoa powder, cinnamon, or nut butter until fully incorporated.
Serve: Spoon into bowls.
Add your favorite toppings and serve immediately for soft-serve texture.
For scoopable ice cream: Transfer to a lidded container and freeze 1–2 hours, stirring once halfway. Let sit at room temp 5 minutes before scooping.
