This air fryer banana cake is quick and easy to put together and bakes up beautifully in the air fryer! It’s a small batch cake that uses up 1 ripe banana.

Baking cake in an air fryer

We had our oven break a little while ago and while waiting for the new one I baked and cooked everything in the air fryer. It cooks much faster than a regular oven, so I bake the cake at a lower temperature until baked through. This stops the top from browning too fast before the middle has had a chance to cook.

The top of an air fryer cake will always be a bit lumpier and interestingly shaped than in the oven, but it doesn’t hinder the flavour and it’s nothing a bit of icing can’t fix!

A few key ingredients

  • A ripe banana – A nice, large brown banana. The riper it is, the more natural sweetness it will bring (and the easier it is to mash.)
  • Greek yoghurt – This brings in some acidity and it makes a more tender cake texture.
  • Butter – salted or unsalted, this brings richness. I use salted butter, I think the extra salt balances the sweet.
  • A large egg – Perfect if you’re running low on eggs!

Method

  1. Grab your air fryer (I use a 5.3L one) and line a 6″ circle pan with parchment paper.

Tips

  • Use really ripe bananas They add natural sweetness and moisture.
  • Don’t overmix the batter so that the cake stays light and fluffy.
  • If your air fryer runs hot, check the cake a few minutes early.

    I made a double batch and it took about an hour to bake all the way through. I was a bit anxious that the long cooking time will impact the flavor and moistness. It did neither. The cake is tasty and moist. I will definitely make this again.
