In a mixing bowl - combine all dry ingredients (flour, garlic powder, onion powder, smoked paprika, salt, black pepper) then whisk in water and milk until batter has no lumps.
Add fresh cauliflower florets to batter and mix well to evenly coat with batter. Remove florets one at a time and transfer to a separate dish so that excess batter can run off.
Coat air fryer basket with non-stick cooking spray or oil, then add battered florets to air fryer basket in a single layer. Also, try to keep them from touching (if possible) so that all sides can get direct heat.
Cook at 350 degrees for 15 minutes.
Meanwhile, in a small pot (or in microwave) - bring hot sauce, butter, and molasses to low simmer, mixing well to combine. Then remove from heat.
Once cauliflower is done cooking, transfer to a bowl. When ready to serve, cover with sauce, then toss to coat.
Serve IMMEDIATELY with your dipping sauce of choice, or none at all. Enjoy!
