Preheat the oven to 400 degrees Fahrenheit.
Prepare your chicken wings by cutting through the joint which connects the middle portion of the wing to the meatiest portion. Then cut through the joint which connects the middle portion to the tip. You will now be left with 3 separate pieces. Discard the tip, or reserve it for another use (see Helpful hints in the post). You will be cooking with the larger two portions of the wing.
Pat the wings dry with a paper towel.
In a medium size bowl use a fork to mix together the baking powder, oregano, salt and pepper.
Add the wings to the bowl and mix well with your hands, ensuring that you coat all parts of the wings with the baking powder mixture.
These wings are best when baked on a rack or pan with a drip tray (as pictured). Spray the surface on which you will place the wings with cooking spray or apply a very light brushing of vegetable oil to it. Place the wings on the baking tray rack being careful not to have the wings touching.
Bake in the lower third of your oven for approximately 30 minutes., flipping them over after 15 minutes.
Once your wings have cooked through, allow them to cool slightly before transferring to a serving platter.
