Over medium heat, add buffalo sauce, brown sugar, rice vinegar, sriracha, minced garlic, and honey to a pot or saucepan. Bring to a simmer to thicken into a glaze. Once it is thick, add the butter, red pepper flakes, and parsley. Mix to combine and then take off the heat and transfer to a large bowl. Set aside.
Pat dry the salmon filets with a paper towel.
Marinade the salmon filets with a drizzle of olive oil and a sprinkle of salt, onion powder, chili powder, and black pepper.
Add the salmon filets to the air fryer at 400°F and cook for 8 to 10 minutes or until crispy on the outside and flakey on the inside.
Take the salmon out of the air fryer and brush a generous amount of the volcano sauce on each filet.
Garnish with sesame seeds and green onions to enjoy!
