Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
In a bowl, mix the flour, garlic powder, onion powder, salt, and pepper.
In another bowl, pour the non-dairy milk.
In a third bowl, place the breadcrumbs.
Dip each vegan cheese stick into the flour mixture, then the non-dairy milk, and finally coat with breadcrumbs.
Place the coated cheese sticks on the prepared baking sheet.
Bake for 15-20 minutes or until golden brown and crispy.
Serve hot with your favorite dipping sauce.
