Add all the ingredients to a food processor and process on high until smooth and creamy. Scrape down the sides as needed.
For a harder texture, transfer the ice cream to a glass container and freeze overnight. If you enjoy "soft serve", serve ice cream immediately.
If freezing overnight, when you're ready to serve simply remove banana ice cream from the freezer and let sit at room temperature for 10 minutes. Scoop into bowls and top with desired toppings!
