Preheat your oven to 425°F (220°C).
Remove any excess moisture from the wings with kitchen paper.
Place the wings into a mixing bowl, add the baking powder and salt, and toss to ensure the wings are evenly coated.
Place the wings on a baking dish with a rack or baking sheet lined with parchment paper, making sure they are arranged in a single layer. (Note 6)
Bake the wings in the preheated oven for about 15-20 minutes. Then turn and cook for another 10-15 minutes until they turn golden brown and crispy. (See note 7 for air fryer instructions)
Meanwhile, prepare the garlic butter sauce. Melt the butter in a saucepan on a medium heat, add the garlic and cook for one minute until fragrant.
Remove from the heat and stir in the parsley.
Remove the wings from the oven. They should be brown and crispy at this point. Brush them with the garlic butter sauce and cook for 5 more minutes until the butter has infused, and the wings are super crispy. (Note 8)
Serve immediately, topped with more fresh parsley if desired.
