Preheat your oven to 350°F (175°C).
Spray a mini muffin pan generously with cooking spray.
Press one wonton wrapper into each muffin cup well.
Bake for 5–7 minutes, or until the wontons become lightly golden and crisp.
Remove from the oven and carefully transfer the wonton cups to a cooling rack.
In a stand mixer bowl, combine cream cheese, blue cheese crumbles, blue cheese dressing, and hot sauce.
Beat until smooth and fully combined.
Add the shredded rotisserie chicken and mix until evenly incorporated and slightly shredded.
Spoon about 1 tablespoon of the Buffalo Chicken Dip Cups filling into each wonton shell.
Arrange the filled cups on a baking sheet.
Cover tightly with foil.
Bake at 300°F (150°C) for 10 minutes, or until the filling is warm, creamy, and gooey.
Remove from the oven and garnish with additional blue cheese crumbles and chopped chives.
Serve warm and enjoy.
