Mei Mei, I used the "bake" function. Remember to lower down the temperature to 130-140 and bake longer, otherwise the cupcakes will look very ugly since the hot air will blow the cake mix to one side.
FatJedi, the airfield cupcake is a little bit more dry compared to oven baked one, but different is not much. The looking of oven version is better and the colour is more even. I don't have oven so I always use air fryer to do baking.
