Freeze the bananas. Slice the bananas and place in a sealed container; freeze for 2 hours.
Combine the ingredients. Add the frozen bananas, yogurt, and honey to a food processor.
Blend. Process until just creamy, stopping to scrape down the sides of the processor if necessary.
Serve. Serve your banana frozen yogurt immediately - it should be more like a soft serve - or transfer it to a sealed container and store it in the freezer.
