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 piece of chicken first in the flour mixture, then dip in the egg, and finally coat thoroughly with cornstarch.
03 - Pour about 1 inch 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. Transfer to a paper towel-lined plate to drain.
05 - Whisk together mayonnaise, sweet chili sauce, Sriracha, honey, rice vinegar, and salt until smooth and fully combined.
06 - Toss the hot chicken pieces with the Bang Bang sauce until evenly coated. Transfer to a serving platter and garnish with chopped scallions, sesame seeds, and cilantro if desired. Serve immediately.
