In a large bowl, melt the butter in the microwave or on a stovetop.
Add the Franks Red Hot and almond flour to the bowl. Mix everything together.
Preheat the air fryer.
Smother the cauliflower head with the buffalo sauce mixture. Add the cauliflower head to the air fryer once ready. If you have an extra large cauliflower you may need to cut it into quarters to fit in the air fryer.
Cook for approximately 14 minutes. This amount of time works great in my air fryer, but default to your manufacturer recommendations for different brands of air fryers. Turn the cauliflower head over as recommended by the manufacturer.
Once the cauliflower is cooked, immediately remove it from the air fryer and place on a serving dish. Toss on the green onions and black sesame seeds and you’re ready to eat!
