Start in cold air fryer. Do not pre-heat. If you cooked something in your air fryer previously and it's still warm, allow it to cool completely. Starting in a pre-heated or warm air fryer will cook the cookie too quick on top and the center can still be raw.
Combine cookie mix according to package instruction. Pour the batter in to the paper pan that was included in the box kit.
Place pan with cookie batter in air fryer basket or rack.
Air Fry at 300°F/149°C for 22 minutes. After the initial base cooking time, stick a toothpick in the cookie. If it's "almost" cooked, turn off air fryer and leave the cake to rest inside the air fryer for about 5-10 minutes to gently finish cooking in the residual heat. If the cookie batter is still wet, Air Fry for 1-3 minutes more or until nearly cooked. Then turn off air fryer and leave the cookie to rest inside the air fryer for about 5-10 minutes to gently finish cooking in the residual heat.
