Adjust oven racks to upper-middle and lower-middle positions.
Preheat oven to 250 degrees. Prepare a rimmed baking sheet with tinfoil and coat its rack with cooking spray. Set aside.
Wash and pat wings dry with paper towel and place in a large resealable bag.
Sprinkle baking powder all over them. Adjust and shake the wings around to ensure they're lightly coated in baking powder.
Place chicken wings on rack of prepared baking sheet.
Season with salt and pepper (or lemon pepper) and bake for 30 minutes on the lower-middle rack.
Remove wings from lower-middle to upper-middle rack and turn the temperature up to 425 degrees.
Bake until wings are a nice golden brown color; between 40 to 45 minutes. Timing will depend on the size of the wings and cooking time could take a little bit longer. Turn baking sheet halfway through baking.
Remove wings from oven and let stand for at least 5 minutes.
Transfer wings to a medium or large bowl.
Serve plain or toss with Caesar salad dressing and sprinkle with Parmesan cheese. Or add wing sauce of your choice, with or without dip.
Serve immediately. Enjoy!
