Cut the bananas into 3 or 4 pieces (or cut them into coins if your food processor or blender is not very powerful), put them in an airtight container and freeze overnight.
Add the bananas to your food processor or blender and blend until you have a super creamy banana ice cream. Be patient, keep blending!
Once it's ready, you can eat it immediately for a soft texture or transfer it to an airtight container and freeze it for at least 1 hour or until solid. When you are going to eat it, if it's too hard, let it stand at room temperature for at least 10 minutes or until it has a perfect consistency.
Serve immediately or keep your nice cream in an airtight container in the freezer for up to 3 months.
Notes
Feel free to customize this banana ice cream recipe however you'd like.
You could also add some sweetener if you'd like it to be sweeter, although I like it better without it.
If your food processor or blender can't blend the frozen bananas, add a splash of any kind of plant milk (coconut milk, cashew milk, or almond milk work very well for making vegan ice cream).
