01 - Preheat oven to 400°F or air fryer to 375°F. Line a baking sheet with parchment paper or spray air fryer basket with nonstick cooking spray.
02 - Place chicken pieces in a mixing bowl and toss thoroughly with salt, black pepper, and garlic powder until evenly coated.
03 - Combine almond flour and grated parmesan cheese in a shallow dish, mixing until well blended.
04 - Press each seasoned chicken piece into the almond flour mixture, ensuring a complete coating on all sides. Shake off excess.
05 - Place coated chicken pieces in a single layer on the prepared baking sheet or in the air fryer basket, ensuring pieces are not touching.
06 - Bake for 15-18 minutes or air fry for 12-15 minutes, turning pieces halfway through cooking, until golden brown and cooked through to an internal temperature of 165°F.
07 - While chicken cooks, whisk together mayonnaise, sriracha, rice vinegar, erythritol, and sesame oil in a medium bowl until completely smooth and emulsified.
08 - Transfer immediately cooked chicken to the bowl with sauce. Toss gently but thoroughly to coat each piece evenly with the spicy cream sauce.
09 - Arrange sauced chicken on a serving platter. Sprinkle with chopped scallions and toasted sesame seeds. Serve immediately while hot.
