Toss cheddar with flour in a bowl to coat evenly.

Combine cream cheese, beer, mustard, Worcestershire, garlic powder, cayenne, and salt in a 6-7 inch air fryer-safe dish.

Preheat air fryer to 320°F.

Cook dish 5 minutes; carefully remove and stir well.

Air fry another 8-10 minutes until cheese fully melts and smooths, stirring every 3 minutes.

Cool 2-3 minutes to thicken slightly; serve warm with soft pretzels, chips, or fresh vegetables.
