Preheat your oven to 250°F (120°C) and line a large baking sheet with parchment paper or lightly grease it.
In a very large mixing bowl, combine the Chex cereal, corn nuts, pretzels, Cheeze crackers, sesame sticks, walnuts, and bagel chips.
In a small bowl, mix together all the sauce ingredients—melted butter, honey, gochujang, Worcestershire sauce, soy sauce, onion powder, garlic powder, salt, and optional cayenne or chili flakes—until well combined.
Pour the sauce over the snack mix and stir gently with a spatula until everything is evenly coated.
Spread the coated mix evenly onto the prepared baking sheet in a single layer. Use two baking sheets if needed.
Bake for 40–50 minutes, stirring every 15 minutes to ensure even coating and prevent burning.
Remove from the oven and let cool completely on the baking sheet.
Store in an airtight container at room temperature for up to 1 week.
