In a large bowl, whisk together the buttermilk, salt, garlic powder, onion powder, paprika, and pepper. Add the chicken tenderloins and marinate for 4 hours or overnight. This is for optimal flavor and texture, but it is still great if you are short on time and can only marinate for a few minutes.
2 cups buttermilk, 1 tsp kosher salt, 1 tsp garlic powder, 1 tsp onion powder, 1 tsp paprika, ½ tsp black pepper, 2 lbs. chicken tenderloins
Preheat the oven to 425°F. Line a baking sheet with parchment paper and place a wire rack on top if available.
In a shallow bowl, combine the crushed cornflakes, panko, smoked paprika, garlic powder, salt, and pepper.
5 cups cornflakes, 1 cup panko breadcrumbs, 1 tsp smoked paprika, 1 tsp garlic powder, 1 tsp kosher salt, ½ tsp black pepper
Remove the chicken from the marinade, letting any excess drip off. Press each tender firmly into the cornflake mixture until completely coated.
Arrange on the prepared baking sheet and lightly spray with cooking spray.
Bake for 18–22 minutes, flipping halfway through, until golden brown, crispy, and cooked through.
While the chicken bakes, melt the butter in a small saucepan. Continue cooking until it turns golden brown and smells nutty, about 3–4 minutes.
6 tbsp unsalted butter
Remove from the heat and whisk in the hot sauce, honey, Worcestershire sauce, lemon juice, and cayenne if using.
⅓ cup Frank's RedHot, 1 tbsp honey, 1 tsp Worcestershire sauce, 1 tsp fresh lemon juice, pinch of cayenne
Arrange the crispy tenders on a platter and drizzle generously with the brown butter buffalo sauce. Do not toss them in the sauce so the coating stays crunchy. Garnish with chives and serve immediately.
