Preheat the oven to 400°F and line a baking sheet with parchment paper.
Place the chicken wings in a large bowl and toss them with the salt and garlic powder until evenly coated.
Arrange the wings in a single layer on the prepared baking sheet and bake for 35 minutes, turning once halfway through.
While the wings bake, melt the butter in a small saucepan over low heat and stir in the hot sauce until combined.
Remove the wings from the oven and transfer them back to the large bowl. Pour the buffalo sauce over the wings and toss to coat.
Return the wings to the baking sheet and bake for 5 more minutes to set the sauce.
Serve the wings hot with the celery and carrot sticks on the side.
