Prepare the ingredients per the instructions above.
Preheat the oven to 350°F (176°C).
Spray ramekins with nonstick spray. In a large bowl, add the rotisserie chicken, half of the mozzarella cheese, cream cheese, buffalo wing sauce, and ranch dressing. Mix until well combined. Transfer the mixture into a ramekin(s) and spread it into an even layer. Top with the remaining mozzarella cheese. Bake for 20 minutes.
Toss the wings with garlic powder, oil, salt, and pepper.
Preheat a grill on medium heat. Grill the wings on all sides to get a nice crispy char to an internal temperature of 160℉ (71℃) using a thermometer.
(Alternatively, use the oven. Cook the wings on a baking sheet in the oven until crispy to an internal temperature of 160℉ (71℃) using a thermometer.)
Toss the wings in buffalo sauce in a bowl.
Serve the wings with buffalo dip with chips, celery sticks, ranch, and beer.
