Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper and place an oven-safe wire rack on top.
Pat chicken wings completely dry with paper towels to ensure maximum crispiness.
In a large bowl, toss wings with baking powder, salt, and black pepper until evenly coated.
Drizzle olive oil over the wings and toss lightly to coat.
Place wings in a single layer on the wire rack, leaving space between each piece.
Bake for 45–50 minutes, flipping halfway through. Increase oven temperature to 425°F for the final 10 minutes for extra crispiness.
Transfer hot wings to a clean bowl and toss immediately with ranch seasoning until evenly coated.
Serve hot for maximum crunch and flavor.
