Preheat oven to 425 degrees. Lightly grease a baking sheet.
In a small bowl, combine dry rub ingredients: baking powder, onion powder, paprika, black pepper, and salt.
Use paper towels to pat dry wings. Toss wings in dry rub, either right on the baking sheet or in a large bowl. Spread wings out in a single layer on the greased baking sheet.
Bake wings for 35-45 minutes (35 for lightly crispy, 40 for crispy [recommended], 45 for extra crispy wings). Toss halfway through.
While wings are in the oven, prepare the garlic parmesan “sauce” by combining parmesan, garlic, olive oil, parsley and lemon juice in a small bowl. Mixture will be pasty.
Use a spoon or sturdy basting brush to add garlic parmesan sauce to each wing. Some of the mixture will fall on the baking sheet. Bake for another 3-4 minutes.
Remove from oven and serve wings hot. Scrape down the baking sheet and use the fallen garlic parmesan mixture as dipping sauce for your wings!
