Preheat the Air Fryer: Preheat your air fryer to 320°F (160°C). This ensures that it's ready to bake your cake.

Mash the Bananas: In a mixing bowl, mash the ripe bananas until they're smooth and no large chunks remain. These bananas will infuse your cake with natural sweetness and flavor.

Prepare the Cake Batter: Add the yellow cake mix, eggs, vegetable oil, and water to the mashed bananas. Mix everything together until well combined. The batter should be smooth and free of lumps.

Grease the Cake Pan: Grease an 8-inch (20 cm) round cake pan with non-stick cooking spray to prevent sticking.

Pour the Batter: Pour the cake batter into the greased cake pan, spreading it evenly.

Air Fry the Cake: Place the cake pan in the preheated air fryer. Cook the cake at 320°F (160°C) for 20-25 minutes. The exact cooking time may vary depending on your air fryer, so check the cake's doneness by inserting a toothpick into the center. It should come out clean when the cake is ready.

Prepare the Pudding: While the cake is cooking, prepare the instant vanilla pudding mix. In a separate bowl, whisk the pudding mix and cold milk together until it thickens. This will be the creamy filling for your cake.

Poke the Cake: Once the cake is done, remove it from the air fryer. While it's still warm, use the handle of a wooden spoon to poke holes evenly across the cake's surface.

Pour the Pudding: Pour the prepared pudding over the cake, ensuring it seeps into the holes you've created. Spread it evenly to cover the entire cake.

Chill the Cake: Place the cake in the refrigerator and let it chill for at least 1-2 hours, allowing the pudding to set and the cake to cool.

Add the Whipped Topping: After the cake has chilled, spread the whipped topping evenly over the pudding layer.

Garnish (Optional): If desired, garnish the cake with banana slices for a decorative touch and an extra hint of banana flavor.

Serve: Slice and serve your Air Fryer Banana Poke Cake, delighting in its moist cake, creamy pudding filling, and fluffy whipped topping.
