Oreo brownies
This batch of brownies uses a whole packet of Oreos – they're crumbled up inside and baked on top – as well as indulgent dark chocolate chips and cocoa powder for an extra chocolatey finish
Heat the air fryer to 160C. Butter and line an 18cm square tin with baking paper. Check that it fits in your air fryer – you may need to remove the perforated basket first. Put the butter and chocolate in a heatproof bowl, then set over a pan of simmering water, making sure the bottom of the bowl isn’t touching the water. Heat gently for 6-8 mins or until melted. Allow to cool slightly, then whisk in the sugar and eggs until well combined.
Stir in the flour and vanilla paste, mix well, then pour into the prepared tin. Bake for 18-20 mins or until cooked but still fudgy in the middle. Allow to cool completely in the tin before slicing. To firm up the fudginess, chill in the fridge for 1 hr before slicing, if you prefer.
