Cut the chicken breasts into bite-sized cubes and place them in a mixing bowl.
Add olive oil, garlic powder, onion powder, paprika, salt, and black pepper. Toss well to coat every piece evenly.
Sprinkle cornstarch over the chicken and toss again until fully coated.
Preheat the air fryer to 400°F (200°C) for 2 minutes.
Place the chicken bites into the air fryer basket in a single layer.
Air fry for 8 minutes, then shake the basket to ensure even browning.
Continue cooking for another 6–7 minutes until golden and crispy.
Meanwhile, prepare the glaze by melting butter in a skillet over medium heat.
Add minced garlic and sauté for 30 seconds until fragrant, being careful not to burn it.
Stir in honey, soy sauce, vinegar, and water. Bring the mixture to a gentle simmer.
Add the cornstarch slurry and whisk until the sauce thickens into a glossy glaze.
Transfer the crispy chicken into the sauce and toss until fully coated.
Allow the chicken to simmer in the sauce for 1–2 minutes to absorb the flavors.
Remove from heat and serve immediately, garnishing with sesame seeds or green onions if desired.
Store leftovers in an airtight container in the fridge.
