Slice the bananas and place them into a Ninja Creami pint container. Start with two and if you still have space until you hit the max fill line, add the other banana.
Freeze for 24 hours, until completely solid.
Remove from the freezer and let sit for 5 minutes.
Run on the “Lite Ice Cream” or “Sorbet” setting.
If the texture is crumbly, use the Re-Spin function until smooth and creamy.
Serve immediately.
Notes
The riper the bananas, the sweeter and creamier the result.
You can add peanut butter or cocoa powder during the Re-Spin for variations.
