Banana Bread in the Air Fryer: Quicker, Cheaper, Better,

Source video by John Kirkwood on YouTube. This recipe was adapted with strict source-fidelity rules and is marked for human review.

John Kirkwood's air fryer banana bread is a creamed-butter cake loaded with two ripe bananas, cinnamon and freshly grated nutmeg. The mixture is folded with self-raising flour and walnuts, then baked in a loaf tin in a preheated air fryer at 160°C for 35 minutes. A sprinkle of demerara sugar on top gives a lovely crunchy crust, while the inside stays soft, light and beautifully moist. Best eaten slightly warm so the banana aroma comes through.

Ingredients

Wet
  • 2 wholeripe bananas, large, mashed with a fork
  • butter, at room temperature
  • sugar
  • eggs, at room temperature
  • vanilla extract
Dry
  • self-raising flour, sifted
  • 2 tspbaking powder
  • ground cinnamon
  • salt
  • nutmeg, freshly grated
Fold-in
  • walnuts, roughly chopped
Topping
  • demerara sugar, coarse, for sprinkling (add late)
For the tin
  • lard, for greasing

Method

  1. Mash 2 large ripe bananas on a plate with a fork until smooth. Set aside.

    ~2 min
  2. Line the base of a loaf tin that fits your air fryer drawer with parchment paper and grease the tin with lard.

    ~2 min
  3. Put the butter and sugar into a medium mixing bowl. Cream together with a spatula. If the butter is too hard, microwave for 5 seconds on full power.

    ~1 min
  4. Swap to a whisk and beat the butter and sugar until light and creamy, about 3 to 4 minutes.

    ~4 min
  5. Add the mashed banana, eggs and vanilla extract. Whisk for 2 minutes. The mix may look grainy from the banana, this is normal.

    ~2 min
  6. In a separate bowl, mix the cinnamon, salt (omit if using salted butter) and freshly grated nutmeg roughly into the self-raising flour. If using plain flour, add 2 tsp baking powder.

    ~1 min
  7. Sift the dry ingredients into the wet mixture. Using a spatula, gently fold together to keep the air in the batter.

    ~2 min
  8. Add the roughly chopped walnuts and gently fold them through.

    ~1 min
  9. Remove the crisp tray from your air fryer. Set to bake mode at 160°C (320°F) and preheat for 3 minutes.

    ~3 min
  10. Scrape the batter into the prepared loaf tin. Tap the tin on the bench to release any large air bubbles. Sprinkle coarse demerara sugar over the top.

    ~2 min
  11. Lower the tin into the air fryer drawer. Bake at 160°C (320°F) for 35 minutes.

    ~35 min
  12. Test in a couple of places with a cocktail or kebab stick. It should come out dry. Lift the tin out carefully and rest on a wire rack for 10 minutes.

    ~10 min
  13. Turn the loaf out of the tin, peel off the parchment, and transfer to a board. Best enjoyed slightly warm.

    ~2 min

Frequently asked

Do I need to preheat my air fryer for banana bread?
Yes. John preheats on bake mode at 160°C for 3 minutes. Preheating helps the cake start rising straight away and gives a more even crumb. If your model has no preheat function, just add 2 to 3 minutes to the total bake time.
Can I use plain flour instead of self-raising?
Yes. Add 2 teaspoons of baking powder to the dry ingredients before sifting, otherwise the cake will not rise.
Why should I remove the crisp tray or rack?
Taking out the crisp tray gives the cake more room to rise and keeps the top further from the heating element, so it doesn't scorch before the centre is cooked.
How do I know when it's done?
Insert a cocktail or kebab stick into the centre in a couple of different spots. If it comes out clean and dry, the banana bread is baked through. If there's wet batter on the stick, give it another 3 to 5 minutes and test again.
Can I bake this in a conventional oven instead?
Yes, John mentions it can also be baked in a conventional oven. As a general guide for a loaf this size, bake at around 170 to 180°C fan for 45 to 55 minutes, testing with a skewer. Check the creator's recipe page for his exact oven times.
Extraction notes (transparency): Transcript describes the full method clearly but does NOT state quantities for butter, sugar, eggs, flour, vanilla, cinnamon, salt, nutmeg, walnuts or demerara topping. Only 2 large ripe bananas and (conditionally) 2 tsp baking powder for plain flour are explicit. Quantities below are marked null and flagged for review; the written recipe page on the creator's website would need to be consulted to confirm amounts.
