Do not use an air fryer model smaller than 3 qt. The cake pan might fit, but a small air fryer usually burns the top of the cake. The heating element will be too close to the cake. Ingredients needed may differ if using a different cake mix.
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 cake too quick on top and the center can still be raw.
Combine cake mix according to package instruction. Pour the batter in to the paper pan that was included in the box kit.
Place cake in air fryer basket or rack.
Air fry at 320°F/160°C for 20 minutes. After the initial base cooking time, stick a toothpick in the cake. If it's "almost" cooked, turn off air fryer and leave the cake to rest inside the air fryer for 5-10 minutes to gently finish cooking in the residual heat. If the batter is still wet, Air Fry for 2-5 minutes more or until nearly cooked. Then turn off air fryer and leave the cake to rest inside the air fryer for 5-10 minutes to gently finish cooking in the residual heat.
Allow to cool. Squeeze the frosting provided over the cake and spread evenly. Enjoy!
