Optional: 1/2 cup chocolate chips or chopped walnuts
Instructions
Step 1: Preparation and Mashing: Start by greasing a 6-inch cake pan or a small loaf pan that fits comfortably inside your air fryer basket. In a medium mixing bowl, peel the overripe bananas and mash them with a fork until they are smooth with only a few small lumps remaining.
Step 2: Mixing Wet Ingredients: Add the melted butter to the mashed bananas and stir well. Mix in the granulated sugar, the beaten egg, and the vanilla extract. Whisk until the mixture is fully combined and smooth.
Step 3: Adding Dry Ingredients: Sprinkle the baking soda and salt over the wet mixture and stir. Gently fold in the all-purpose flour. Be careful not to overmix the batter; stir just until the flour streaks disappear. If you are using chocolate chips or nuts, fold them in now.
Step 4: Air Frying the Bread: Pour the batter into your prepared pan and smooth the top with a spatula. Place the pan into the air fryer basket. Set the air fryer to 320°F (160°C) and bake for 30 to 35 minutes. At the 30-minute mark, insert a toothpick into the center; if it comes out clean, the bread is done.
Step 5: Cooling: Carefully remove the pan from the air fryer and let it sit on a wire rack for about 10 minutes. Once cooled slightly, remove the bread from the pan and let it cool completely before slicing.
