Add oils to a liquid measuring cup along with all of the spices. Whisk to combine.
Add rice chex, corn chex, wheat chex, pretzels, rye chips and peanuts to a very large bowl. Pour 1/3 of the oil over. Stir then pour another 1/3. Stir and pour remaining 1/3 over. Continue to stir until evenly coated in the spices and oil. Let the mixture sit for 5 minutes, then stir again. Let it sit another five minutes and then pour on to a large, rimmed baking sheet.
Bake chex mix for 15 minutes, then stir, repeat three more times for a total of one hour of cooking. Let cool and store in an airtight container.
