In a large mixing bowl, use a wooden spoon or rubber spatula to gently fold together pretzel snaps, parmesan Goldfish, cheddar and sour cream chips, honey BBQ Fritos, oyster crackers, and white cheddar Cheez-Its.
Melt butter in a microwave safe dish. Then, whisk in 1 packet of dry ranch seasoning mix. Next, whisk shaved parmesan cheese into the butter and ranch mixture
Pour the butter mixture over the snack bowl and toss well. You really want to make sure all the snacks are coated.
Pour the snack mix onto a baking sheet. Sprinkle the ranch powder packet onto the snack mix and gently toss around. Bake for 1 hour.
While the snack mix is baking, remove to mix 2-3 times to prevent burning. Allow to cool for 15 minutes then dig in!
