Make sure the bananas are at least partially brown before chopping and freezing them. Combine all ingredients in a blender or food processor. Process until completely smooth, adding a little milk of choice if your blender isn’t strong enough to handle the frozen banana. Either serve immediately as soft serve, or freeze for up to an hour before scooping out with an ice cream scoop. For extra crispy & deliciousness add a PB & Chocolate Super Pop bar.
