Cut the eggs in half and scoop out the yolks into the bowl of a stand mixer fitted with a whisk attachment; set the whites aside. Add the mayo, ranch and hot sauce. Add salt and pepper to taste and whip until smooth. Fold in the blue cheese and diced celery using a rubber spatula.
Using a small spoon, fill each egg white half with a generous mound of filling. Top with the extra blue cheese and reserved celery leaves and serve.
