Preheat oven to 400°. In a medium bowl, combine cream cheese, ¼ cup buffalo sauce, cheddar, and chives. Season with salt and pepper.
Using a sharp knife, carefully cut a pocket in side of each chicken breast. Divide filling evenly between breasts and place in a large baking dish. Season tops with salt and pepper.
Bake until chicken is no longer pink and internal temperature is 165°, 30 minutes.
Turn oven to broil. Brush remaining ¼ cup buffalo sauce over chicken and broil until golden in spots, 5 minutes.
Drizzle with blue cheese dressing and garnish with more chives before serving.
