Preheat oven to 325 degrees.
In a small saucepan, combine avocado oil through garlic powder. Stir. Heat on low-medium heat, stirring frequently, until sugar dissolves and bubbles around the edge for about one minute. Careful not to burn or overcook! It will thicken up a tiny bit.
Spread popcorn, pretzels, and nuts evenly on a baking sheet. May want to cover baking sheet with foil or parchment for easier cleanup. Pour sauce evenly over snacks in the pan. Stir gently to combine and spread out evenly.
Bake for 8 minutes. Stir gently. Bake another 2-5 minutes. Allow to cool completely before packing in an airtight container.
