Creating Bang Bang Chicken is simple and straightforward. Follow these steps for a delicious result:

1. Marinate the Chicken: In a bowl, soak the chicken breasts in buttermilk for at least 30 minutes. This helps tenderize the meat and adds flavor.
2. Prepare the Coating: In a shallow dish, combine flour, garlic powder, paprika, salt, black pepper, and cayenne pepper.
3. Heat the Oil: In a large skillet, heat about 1 inch of vegetable oil over medium-high heat until it shimmers.
4. Coat the Chicken: Remove the chicken from the buttermilk, allowing excess to drip off. Dredge each piece in the flour mixture, ensuring a thorough coating.
5. Fry the Chicken: Carefully place the coated chicken in the hot oil. Fry for about 5–7 minutes on each side or until golden brown and cooked through.
6. Drain Excess Oil: Once cooked, transfer the chicken to a paper towel-lined plate to drain any excess oil.
7. Make the Bang Bang Sauce: In a bowl, whisk together mayonnaise, sweet chili sauce, sriracha, lime juice, and sesame oil until smooth.
8. Combine: In a large bowl, toss the fried chicken pieces in the Bang Bang sauce until evenly coated.
9. Garnish: If desired, sprinkle chopped green onions on top for added flavor and presentation.

These straightforward instructions will guide you in creating a dish that is sure to impress.
