01 - Set up three shallow bowls: combine flour, garlic powder, paprika, salt, and pepper in the first; beat eggs in the second; place cornstarch in the third.
02 - Dredge each chicken piece first in the flour mixture, then dip in the egg, and finally coat thoroughly with cornstarch.
03 - Pour 2–3 inches of vegetable oil into a deep skillet and heat over medium-high heat until shimmering.
04 - Fry chicken pieces in batches, turning occasionally, until golden brown and cooked through, approximately 5–6 minutes per batch. Drain on paper towels.
05 - Whisk together mayonnaise, sweet chili sauce, Sriracha, honey, rice vinegar, and salt until completely smooth.
06 - Toss the hot chicken pieces with the Bang Bang sauce until well coated. Transfer to a platter and garnish with scallions, sesame seeds, and cilantro if desired.
