Place the pretzels in a gallon sized bag and set aside.
In a small bowl combine the garlic powder, paprika, onion powder, ranch seasoning, and brown sugar. Mix well and set aside.
Combine the vegetable oil and Frank's RedHot Buffalo Wings Sauce in a small bowl. Pour over top of the pretzels in the bag. Zip the bag shut and shake well.
Open the bag and pour in the seasoning mix. Zip the bag shut and shake well.
Pour the pretzels onto a large baking sheet with a rim.
Bake for 30 minutes, stirring halfway through the cooking time to prevent burning.
Once the pretzels are cooked remove from oven and cool completely. Keep in an air tight container for up to 1 week.
