Cut end of corn to fit air fryer basket. If needed for smaller air fryer, cut the corn in half. Coat all sides of the corn with melted butter. Season with salt and pepper around the whole corn.
Air Fry at 370°F/190°C for 12-16 minutes, flipping half way. Cook until kernels are tender and lightly browned. (Cooking time will depend on size of corn, how full air fryer basket is, & different models/sizes of air fryers)

Transfer corn to a platter and spoon cheese mixture over the corn. Sprinkle with extra cheese, paprika or chili powder, green onions and/or chopped cilantro. Serve with lime wedges.
