Line two baking sheets with parchment paper and place a wire rack on top of each. Spray the racks with nonstick spray.
Place wings in a large bowl and thoroughly dry with paper towels.
Mix baking powder, salt, ranch seasoning, garlic powder, and onion powder together in a small bowl.
Sprinkle the ranch seasoning mixture evenly over the wings and toss to coat, pressing the wings into the seasoning as needed.
Evenly place on the racks, sprinkle with remaining seasoning and chill for at least 1 hour and up to 12.
Preheat oven to 425 degrees.
Bake the wings for 25 minutes. Flip the wings, and continue to bake until they are crisp and golden brown about 10 minutes.
Serve immediately with your favorite sauce.
