Bake in preheated oven until the nuts are golden brown, about 30 minutes. Stir the mixture 2 or 3 times to ensure even cooking. Once done, scrape the peanuts into a large metal bowl, and sprinkle with the spice mixture. Toss the peanuts to evenly coat with the spice mixture. Allow the peanuts to cool to room temperature, tossing every few minutes so the nuts do not stick together.
