Peel and slice the bananas into 1-inch slices.
Spread the banana slices and strawberries inside a 1 gallon ziploc bag and freeze overnight or until frozen solid.
In a food processor or high-powered blender, blend the frozen banana slices and the rest of the ingredients together until smooth.
Serve immediately as a soft serve, or pour into a lidded glass container and cover and freeze.
For best ice cream consistency, take the container out of the freezer and let sit at room temperature for 10 minutes. If it’s in a microwaveable container, you can also microwave it for 15 seconds until softened.
