METHOD In your mixing bowl, add the cake mix, butter, water and chocolate chips. Mix everything together until it forms a thick dough. Spoon the dough into ramekins and press it down to create a smooth, even layer. Place the ramekins in your air fryer at 160°C and cook for 12-14 minutes. Serve warm with a scoop of ice cream on top and a sprinkle of marshmallows.
