Pour the almond milk and bananas into a small blender and blend the ingredients together until the banana has fully combined with the almond milk.
Freeze on a level surface for 24 hours. Your freezer should be between 9 and -7 degrees Fahrenheit. To avoid getting a bump on the top of the frozen mixture, freeze with the lid off of the container.
Process the Ice Cream
Place the pint container into the outer bowl of the Ninja Creami and then process on "LITE ICE CREAM."
If the ice cream is dry or crumbly looking, pour in a tablespoon or two of milk and then re-spin. If the ice cream looks more like dippin dots, (little balls of ice cream), re-spin without adding liquid.
Dig a well down the center of the ice cream and pour in the chocolate chips. Process on mix-ins.
