Cream together the butter and sugar until light and fluffy.

Add the egg and mix well, then fold in the self-raising flour, baking powder and mashed banana until just combined – don’t overmix.

Spoon the mixture into your silicone moulds – I use a silicone egg bites mould for 7 small cakes and a couple of larger moulds for the choc chip versions. Or you can do the bites in 2 batches.

Pop them in the air fryer and bake at 160°C for 15 minutes using Bake Mode. (If you don't have bake mode - just use the regular air fryer setting and keep an eye on them near the end of the cook time - bake mode just slows the fan down).

You can test if they’re done by inserting a skewer - when it comes out clean, they’re ready.

Let cool slightly before removing from the moulds. Super light, naturally sweet, and lunchbox-ready!
