Coat the chicken in buttermilk: Add the 1 pound chicken pieces and 1/3 cup buttermilk to a shallow bowl. Toss to coat the chicken and set aside.
Whisk dry ingredients: Whisk together the 1 cup flour, ¼ cup cornstarch, 2 teaspoons sugar, 2 teaspoons salt, ½ teaspoon black pepper, ½ teaspoon garlic powder, ½ teaspoon onion powder, and ½ teaspoon paprika in a separate shallow bowl.
Put buttermilk in a bowl: Add the remaining ⅔ cup buttermilk to a third shallow bowl.
Coat chicken three times: Using a fork, take a single buttermilk-coated piece of chicken and place it into the flour mixture. Lightly coat with flour then move it to your third bowl to coat it in buttermilk. Return it back to the flour mixture and heavily coat. Place on a baking sheet lined with parchment paper and repeat with the remaining chicken pieces.
Let chicken rest: Once all pieces are coated, allow to rest for 10 minutes.
Heat the oil: To a heavy skillet, add 1 inch of oil and heat over medium.
Cook chicken in the oil: When the oil reaches 375°F, add the chicken pieces in batches of 8-10 pieces and cook for 4-5 minutes, flipping halfway through. The chicken should be golden and the internal temperature should reach 165°F.
Remove chicken: Remove the chicken onto a paper towel lined baking sheet and repeat until all chicken is cooked.
Toss chicken in sauce: Toss half of the chicken in ½ cup buffalo sauce and the other half in ½ cup honey barbecue sauce. Or, use 1 cup of your choice of sauce to coat all the boneless chicken wings.
Serve: Serve immediately.
