In a large bowl, combine flour, salt, onion powder, garlic powder, and black pepper. Mix well, then add the chicken thighs, ensuring each piece is thoroughly coated. Set aside for about 10 minutes.

Heat a skillet over medium-high heat and add 1 tablespoon of butter and a splash of olive oil. Once melted, carefully add the coated chicken pieces. Fry for about 5-7 minutes per side until golden brown and cooked through.

In the same skillet, reduce heat to medium and add 3 tablespoons of unsalted butter. Once melted, stir in honey, apple cider vinegar, and soy sauce. Simmer for 3-4 minutes until thickened.

Return the fried chicken to the pan and gently stir until each piece is well-coated in the glaze. Cook together for another 2-3 minutes.

Remove from heat and serve immediately, garnished with green onions or sesame seeds if desired.
