Preheat and Prepare: Preheat your oven to 400°F (200°C). Place two oven-safe racks on two rimmed baking sheets lined with parchment paper. Spray the racks with oil and set them aside.
Prepare the Wings: In a large bowl, wash the chicken wings, drain them, and pat them dry with paper towels. Add the oil and half of the lemon-pepper seasoning to the wings, tossing to coat evenly. Sprinkle the baking powder over the wings and toss again to coat evenly.
Bake the Wings: Arrange the wings on the prepared racks in a single layer, making sure not to overcrowd them. Bake in the preheated oven for 30 minutes.
Flip and Continue Baking: After 30 minutes, remove the wings from the oven and flip them over. Return to the oven and bake for another 20 minutes.
Flip and Continue Baking: After 30 minutes, remove the wings from the oven and flip them over. Return to the oven and bake for another 20 minutes.
Prepare the Lemon Butter Sauce: While the wings are baking, in a separate large bowl, combine the melted butter, lemon zest, and the remaining lemon-pepper seasoning.
Coat and Serve: Once baked, add the wings to the bowl with the lemon butter sauce. Toss to coat evenly. Transfer the wings to a serving platter and enjoy immediately!
