In a large mixing bowl whisk together the BBQ sauce, honey, and apple cider vinegar. Set aside.
In a shallow bowl add the cornstarch, salt, pepper, garlic powder, onion powder, chili powder, and paprika. Whisk together.
In a second shallow bowl add the egg and milk and whisk together.
Pat the chicken dry with paper towels.
Work in batches to dredge the chicken in the cornstarch mixture, shaking off excess. Next, place the chicken pieces in the egg to coat, letting excess drip off. Last, dredge one more time in the cornstarch mixture. Set on a clean plate and continue this process until all the chicken is coated.
In a large skillet, heat 3 tablespoons of oil over medium high heat. Once the oil is glistening, add about half the chicken pieces and fry for 2 minutes. Rotate the chicken pieces and cook an additional 2-3 minutes or until chicken reaches 165 degrees F and is cooked through.
Remove to a paper-towel lined plate and cook the second batch of chicken.
Gently toss the chicken in your prepared sauce and serve warm.
