This spicy and bold chex mix is so good and addicting. The flavors of buffalo hot sauce, ranch seasoning, and parmesan go together so well. This chex mix won't be around for very long.
In a large baking dish combine all of the ingredients in the order that they occur on the list. Stir well before adding the oil, continue to stir to make sure all of the ingredients are fully coated with the oil, hot sauce, worcestershire, ranch, and parmesan.
Bake for 1 hour stirring every 20 minutes or until all pieces are crunchy. Let cool to room temperature before eating to ensure each piece crisps up.
