Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper or spray with nonstick cooking spray.
In a medium bowl, combine the shredded chicken, buffalo sauce, cream cheese, and shredded cheddar. Stir until everything is well mixed and creamy.
Separate the biscuit dough and flatten each piece slightly. Place a spoonful of the buffalo chicken mixture into the center of each round. Fold the dough around the filling and pinch the seams to seal. Roll gently into a ball shape.
Place the filled dough balls seam-side down on the baking sheet. Brush the tops with melted butter and sprinkle with garlic powder. Bake for 13–15 minutes, or until golden brown and cooked through.
Let cool slightly, then serve warm with ranch or blue cheese dressing. Garnish with chopped parsley or green onion if desired.
