1. Prepare the Chicken Pieces: Start by patting your chicken pieces dry with paper towels. This step is crucial for achieving a crispy exterior. In a shallow bowl, combine the flour, salt, and black pepper. Toss the chicken pieces in this mixture until they are evenly coated, shaking off any excess flour.

2. Sear the Chicken: Heat 1 tablespoon of the unsalted butter in a large non-stick skillet or cast-iron pan over medium-high heat. Once the butter is melted and shimmering, add the floured chicken pieces in a single layer, making sure not to overcrowd the pan. You might need to cook the chicken in two batches to ensure even browning and crispiness.

3. Brown the Chicken Evenly: Cook the chicken for about 3-4 minutes per side, or until golden brown and cooked through. The internal temperature should reach 165 F (74 C). Remove the cooked chicken from the skillet and set it aside on a plate. If cooking in batches, add another tablespoon of butter for the second batch if needed.

4. Prepare the Honey Butter Sauce: Reduce the heat to medium-low. Add the remaining 2 tablespoons of unsalted butter to the same skillet. Once melted, stir in the honey, apple cider vinegar, garlic powder, onion powder, and red pepper flakes (if using). Whisk constantly for 1-2 minutes until the sauce is smooth and slightly thickened.

5. Glaze the Chicken: Return all the cooked chicken pieces to the skillet with the honey butter sauce. Toss gently with tongs or a spatula, ensuring every piece of chicken is thoroughly coated in the sweet and savory glaze. Continue to cook for another 1-2 minutes, stirring constantly, until the sauce has thickened and beautifully clings to the chicken.

6. Serve Immediately: Transfer the honey butter chicken bites to a serving platter. Garnish with fresh chopped parsley or chives, if desired, for a pop of color and freshness. Serve hot and enjoy!
