Bake a moist and flavorful banana bread in your PowerXL Air Fryer. Mash ripe bananas and mix them with melted butter, sugar, eggs, and vanilla extract. In a separate bowl, combine flour, baking soda, and salt. Gradually add the dry ingredients to the banana mixture and mix until just combined. Pour the batter into a greased loaf pan that fits in the air fryer basket. Cook at 325°F for 40-45 minutes, or until a toothpick inserted in the center comes out clean. Enjoy a homemade banana bread that's perfect for breakfast or a sweet treat.
