Prep & Season: Peel and slice two bananas in half lengthwise. Place them in the air fryer basket, cut-side up. Mix 1 tbsp brown sugar and 1/2 tsp cinnamon, then sprinkle it over the bananas.
Cook: Air fry for 6-8 minutes, until the topping is bubbly and the bananas are golden brown and soft.
Serve: Carefully remove from the basket and serve warm.
