Follow these straightforward steps to create your Bang Bang Chicken:

1. Marinate the Chicken: Place chicken breasts in a bowl and pour buttermilk over them. Let them marinate for at least 15 minutes.
2. Prepare the Flour Mixture: In a shallow dish, mix flour, garlic powder, paprika, cayenne pepper, salt, and pepper.
3. Coat the Chicken: Remove the chicken from the buttermilk, allowing excess to drip off. Dredge each piece in the flour mixture, coating evenly.
4. Heat Oil: In a large skillet or frying pan, heat enough oil to cover the bottom over medium-high heat.
5. Fry the Chicken: Once the oil is hot, add chicken pieces in batches, being careful not to overcrowd the pan. Fry for about 5-7 minutes per side or until golden brown and fully cooked.
6. Make the Bang Bang Sauce: While the chicken cooks, whisk together mayonnaise, sweet chili sauce, sriracha, and lime juice in a bowl.
7. Remove and Drain: Place fried chicken on a plate lined with paper towels to absorb excess oil.
8. Toss in Sauce: In a large bowl, gently toss the fried chicken with the Bang Bang sauce until evenly coated.
9. Garnish: Sprinkle chopped green onions over the top for added flavor and aesthetics.
10. Serve Immediately: Enjoy your Bang Bang Chicken while still hot.
