Preheat machine to 310 degrees F. Mix dry ingredients in one bowl and wet including mashed bananas in the other.
Slowly incorporate dry into wet and use a spoon to mix but leave bits of banana chunks in tact.
Spray inside of bundt pan lightly with non stick spray.
Pour batter into mini bundt and place inside air fryer basket. Cook at 310 degrees for a total of 28 minutes or until toothpick comes out mostly clean with moist crumbs attached and lightly brown on top. Remove and allow to sit for 5 minutes.
Put a plate on top and gently flip over so bread slides out. Can flip back over so bottom is more flat on plate.
Slice and serve or drizzle with slightly melted vanilla frosting and enjoy.
