Preheat your oven to 375°F (190°C).
Lightly spray a muffin tin with cooking spray and gently press a wonton wrapper into each muffin cup to form a cup shape.
In a mixing bowl, combine the softened cream cheese, Frank's RedHot sauce, and ranch dressing. Stir until smooth, then add the finely chopped chicken and chives.
Spoon the buffalo chicken mixture into each wonton cup, filling them generously.
Bake for 12-15 minutes until the wonton wrappers are crispy and golden brown.
Allow the cups to cool for a few minutes before serving. Garnish with additional chives if desired.
