Grind peppercorns and cumin seeds to a powder. Place in a bowl. Add salt, garlic powder, onion powder and cinnamon. Mix it up.
Pat dry chicken wings with paper towels. Coat the wings in the spice blend, mix well. Place the wings on a rack on top of a foil lined baking sheet. Cook in the heated oven for approximately 45 minutes turning the wings halfway through cooking. Cool for 5 minutes and enjoy! These wings taste great on their own. Ranch dressing is a good choice served on the side to cut the heat.
