Prep the chicken. Pat the chicken dry with paper towels. This helps the coating stick and promotes browning. Cut into even 1-inch pieces for quick, uniform cooking.
Season and coat. In a large bowl, toss chicken with oil, salt, pepper, garlic powder, smoked paprika, and onion powder.
Sprinkle in the cornstarch and toss until every piece looks lightly coated and no dry pockets remain.
Preheat the air fryer. Set to 400°F (200°C) for 3–5 minutes. A hot basket jump-starts crisping.
Load the basket. Arrange chicken in a single layer with a little space between pieces. Work in batches if needed.
Lightly mist with oil if your air fryer tends to run dry.
Air fry. Cook at 400°F for 8–10 minutes, flipping or shaking the basket halfway. Cook until golden with crisp edges and an internal temperature of 165°F. If needed, add 1–2 more minutes for extra color.
Make the hot honey. While chicken cooks, warm honey, hot sauce, and vinegar in a small saucepan over low heat just until thin and glossy.
Stir in red pepper flakes and a pinch of salt. For a richer finish, whisk in the butter off heat.
Toss to coat. Transfer the hot chicken bites to a bowl and drizzle with the hot honey sauce. Toss gently until each piece gleams.
Start with half the sauce, taste, and add more as you like.
Finish and serve. Top with chopped herbs or sesame seeds. Serve immediately over rice, with a simple salad, or as a snack with lemon or lime wedges.
