In a small bowl, mix together the buffalo sauce and oil or butter. Place the cauliflower florets in a large ziplock bag. Add the sauce and a pinch of salt then shake the bag to evenly coat the cauliflower. Use your hands or tongs to transfer the coated cauliflower florets into a large mixing bowl (see notes).
In a small bowl, combine the garlic powder, herbs (if using), paprika, gluten free flour, cornstarch, and remaining salt. Gradually sprinkle the flour mixture over the cauliflower florets, tossing or shaking until all the florets are coated.
Preheat the air fryer to 400 degrees Fahrenheit.
Once the air fryer has preheated, add the cauliflower to the air fryer basket, making sure they are evenly spaced. Depending on the size of your air fryer, you might need to work in two batches.
Spray the cauliflower with cooking oil. Air fry for 16- 18 minutes, shaking the cauliflower every 5 minutes through cooking. Spray with cooking oil again after tossing halfway. Note – Check for doneness at 14-15 minutes if your cauliflower floret are on the smaller side. The florets are done when lightly browned and crispy on the edges.
Brush the cauliflower with extra sauce, if desired, before serving.
Store leftovers in a sealed container in the fridge for up to 4 days.
