Step 1

Preheat the air fryer to 380 degrees F (190 degrees C). Spray basket with cooking spray.

Step 2

Pat chicken wings dry with a paper towel. Whisk together baking powder, salt, pepper, and paprika; pour into a resealable plastic bag. Place some of the chicken wings into the bag and give it a good shake until wings are well coated. Shake off excess baking powder mixture and repeat with remaining wings until all wings are coated.

Step 3

Place chicken wings in the air fryer basket, and cook, flipping halfway through, 22 to 23 minutes.

Step 4

Meanwhile, combine vinegar, pineapple juice, ketchup, brown sugar, soy sauce, Sriracha, and sesame oil in a small saucepan over medium heat. Stir well and bring to a boil. Boil for about 2 minutes. Reduce heat to a simmer. Stir cornstarch and water together in a small bowl, pour into the saucepan, and quickly whisk until sauce thickens, about 1 minute. If sauce is too thick, thin out with a little water.

Step 5

Increase air fryer temperature to 400 degrees F (200 degrees C) and cook wings until cooked through and crispy brown, about 2 more minutes.

Step 6

Pour sauce into a large bowl and add the cooked wings. Toss to coat well. Garnish with sesame seeds and green onion and serve immediately.
