For a baked alternative, preheat oven to 425°F (220°C). Place breaded chicken on a wire rack over a baking sheet, lightly spray with oil, and bake for 15-18 minutes until cooked through and crispy. The Bang Bang sauce can be made spicier by adding more sriracha or a pinch of cayenne. For best results, let the chicken marinate in the buttermilk for at least 30 minutes, or up to 4 hours, for extra tenderness. Assemble sliders just before serving to prevent the buns from getting soggy.
