Preheat oven to 220°F. Pour pretzels on a baking sheet lined with a silicone matt or parchment paper.
Whisk together oil, cheddar powder, and garlic powder. Pour over pretzels and toss to coat.
The pretzels will soak up all the oil if you continue to stir every 15 minutes but to speed up the process I recommend baking them at 220°F for 10-15 minutes until they are dry.
That's it! Snack away!
