01 - Preheat oven to 400°F or heat air fryer to 375°F. Line a baking sheet with parchment paper or spray air fryer basket with nonstick spray.
02 - In a bowl, toss chicken pieces with salt, black pepper, and garlic powder until evenly coated.
03 - Mix almond flour and parmesan cheese in a shallow dish until well combined.
04 - Dredge each seasoned chicken piece in the almond flour mixture, pressing lightly to ensure thorough coating.
05 - Place coated chicken pieces on the prepared baking sheet or in air fryer basket in a single layer.
06 - Bake for 15–18 minutes or air fry for 12–15 minutes, turning halfway through, until golden brown and cooked through with internal temperature reaching 165°F.
07 - While chicken cooks, whisk together mayonnaise, sriracha, rice vinegar, sweetener, and sesame oil in a bowl until completely smooth and well incorporated.
08 - Transfer cooked chicken immediately to the bowl with sauce. Toss gently but thoroughly to coat each piece evenly with the spicy cream sauce.
09 - Transfer sauced chicken to a serving platter. Sprinkle generously with chopped scallions and toasted sesame seeds. Serve immediately while hot.
