Equipment

Ingredients

1 cup all purpose flour
½ teaspoon baking powder
½ teaspoon baking soda
¼ teaspoon salt
½ cup + 2 tablespoons mashed banana about 2 medium
½ cup light brown sugar packed
½ cup sour cream or plain yogurt
¼ cup vegetable oil
1 large egg
1 teaspoon vanilla extract
3 tablespoons chopped Walnuts for topping (optional)

Instructions

Preheat the air fryer to 340°F. It will run empty during this time, which helps jump-start the baking process. While it preheats, prepare the cake batter.
Grease a 6-inch round cake pan with cooking spray and set aside.
Add the flour, baking powder, baking soda and salt into a small bowl and whisk to combine.
In a large bowl, combine the mashed banana, brown sugar, sour cream, oil, egg, and vanilla. Whisk until smooth and well blended.
Add the flour mixture and gently fold it in using a rubber spatula, mixing just until combined.
Transfer batter to the prepared pan, smooth top and sprinkle chopped walnuts on top.
Set the air fryer to 330°F for 35 minutes. Once ready, place the cake pan into the air fryer basket and bake until the cake is golden brown and fully cooked through.
👉 Let the air fryer run at 340°F for at least 6 minutes, or until you're ready to place the cake inside. Then, reduce the temperature to 330°F and bake the cake.
Check for doneness by inserting a toothpick into the center of the cake—it should come out clean or with just a few moist crumbs.
👉 Baking Time – Air fryer cake tend to develop a darker top compared to oven-baked one. While the surface may look fully baked, the inside might still be undercooked. Start checking at the 35-minute mark using a toothpick or thin knife. If it doesn’t come out clean, continue baking for another 5 to 10 minutes.
Place the cake pan on a wire rack to cool completely. Slice and enjoy!

Notes

Bananas – Mash the bananas thoroughly. I prefer using a potato masher for a smoother texture, but a fork works just fine too.

How many bananas? – You’ll need two medium or one large banana for this recipe. Be sure to measure the mashed banana to match the quantity specified in the recipe, as the exact amount is key for the right texture.

Cake Pan – A 6-inch round baking pan works perfectly.

Air Fryer Used – This recipe was tested in the Instant Pot 6-quart Vortex Air Fryer. Cooking times may vary slightly depending on your air fryer model.
