Why this works

Browning the butter removes its water content and toasts milk solids for deep flavor, while a balanced ratio of ripe bananas and minimal mixing ensures a tender, moist crumb without toughness.

Watch for

Overmixing the batter develops excess gluten, resulting in a tough, rubbery loaf; mix only until the flour disappears.
Premature top burning in the air fryer can be prevented by tenting the pan with a small piece of aluminum foil partway through cooking.
