Add 1 tablespoon Milkand 120 g Chocolate chips.
Use your hands to mix together and form into a ball of dough.

Cook at 160°C/320℉ for 10 minutes.
Allow to cool on a wire rack for 5 minutes.
Notes
For best results, chill the dough for at least 30 minutes (although you can chill a day in advance). This allows the butter to solidify and stop them spreading so much when cooking.
Make sure there is space in the air fryer between each cookie as they will rise and spread.
Leave the cookies to rest in the air fryer basket, out of the air fryer, for 5 minutes before moving them on to a cooling rack.
When the air fryer cookies have finished cooking, press a couple of chocolate chips into them before they cool, to make them look extra chocolatey.
If you have any leftover cookie dough, you can wrap it up and put in an air tight container and it will keep in the fridge for up to a week.
You can use this recipe to make mini air fryer cookies too.
