Preheat the oven or air fryer to 180°C. Line a baking tray with baking parchment or prepare a silicone liner that fits your air fryer.
Mash the bananas with the vanilla extract until smooth.
Stir in the oats, chopped apricots and chia seeds until well combined.
Leave the mixture to rest for 5–10 minutes so the oats can absorb some of the moisture.
Divide the mixture into about 8 portions. Shape each into a ball, then flatten slightly between your palms to form cookies.
Arrange the cookies on the prepared baking tray or in the air fryer basket, leaving a little space between them.
Bake in the oven for about 15–18 minutes, or until lightly golden.
Alternatively, bake in the air fryer for about 12–15 minutes, turning the cookies halfway through cooking.
Leave to cool on the tray for a few minutes before transferring to a wire rack to cool completely.
