If you're craving some deeply chocolatey, perfectly fudgy little brownie squares without having to turn the oven on, these air fryer brownies are for you.
Put the dark chocolate and butter in a large microwave-safe bowl. Microwave in 30-second bursts, stirring between each burst until melted. Avoid overcooking as this can negatively affect the chocolate.
Add the caster sugar, beaten eggs and vanilla and stir through with a manual whisk - I say stir as you don’t want to add air but a whisk is still the best tool as it distributes everything quickly.
Put the flour through a sieve into the bowl. Stir to combine.
Stir in the chocolate chips.
Pour the brownie batter into your greased tin and level off.
Set the air fryer to 140C/285F and bake for 35 minutes until a skewer pushed into the centre comes out with sticky crumbs.
Allow to cool in the tin, then chill overnight to make them easy to slice.
Slide onto a serving board and slice in 16 pieces (in a pattern of 4 by 4).
