Place the chicken wings into a 6-quart crock pot. Pour the hot sauce over the wings and stir to coat. Cut the butter into pieces and lay them on top of the wings.
Cover and cook on HIGH for 2 hours, stirring halfway through the cooking time.
Remove the wings from the slow cooker and place them onto a foil-lined baking sheet in a single layer.
Broil the wings for 3-4 minutes then baste them with the sauce and flip the wings over. Then continue broiling until they're crisped up the way you like.
Drizzle with more sauce before serving with blue cheese and/or ranch dressing, carrot sticks, and celery sticks.
Notes
If you are using frozen chicken wings, be sure to thaw the chicken ahead of time before adding them to the crock pot.
