Preheat oven to 400 degrees. Line a large cookie sheet with aluminum foil. Place a raised wire rack (like a cookie cooling rack) on top of the cookie sheet and spray with cooking spray.
Dredge the chicken tenderloins in the flour, then dip into the buffalo sauce mixture. Next dip into the panko breadcrumbs and coat well, pressing the panko into the chicken.
Spray the tops of the chicken with oil or cooking spray, then bake in the preheated oven for 8-10 minutes. Flip the chicken fingers and bake for an additional 8-10 minutes.
