Butter a 20cm (8inch) cake tin.
Melt the butter, sugar and syrup in a pan.
Put the oats in a bowl and add the melted butter mixture. Combine together and then add to the cake tin. Press down well into the tin until it's flat.
Put the low trivet into the instant pot with the cake tin on top.
Put the air fryer lid on and set to bake for 12 minutes at 185c (365f).
Remove the lid and the cake tin. Place on a cooling rack. Leave to cool for around 1 hour and then cut into triangles.
Serve and enjoy.
