In a large bowl, combine all-purpose flour, garlic powder, cayenne pepper, onion powder, salt, and black pepper. Mix well until all spices are evenly distributed. Coat the chicken breasts thoroughly in this flour mixture.

In a cast iron skillet, heat 2 tablespoons of unsalted butter and 2 tablespoons of canola oil over medium heat. Once melted, place the coated chicken breasts in the skillet. Cook for about 2-3 minutes on each side until golden brown.

Lower the heat to medium-low and add the remaining 2 tablespoons of butter. Stir in honey, soy sauce, apple cider vinegar, and a pinch of salt and pepper. Mix continuously for 3-5 minutes, letting the sauce thicken.

Return the cooked chicken to the skillet, tossing it in the honey glaze until fully coated. Let it simmer in the sauce for another 3-4 minutes.

Remove from heat and let the Honey Butter Chicken rest for about 5 minutes to retain juices and allow flavors to meld.

Transfer to a serving plate and garnish with freshly chopped green onions. Serve alongside rice and vegetables.
