Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.
In a large mixing bowl, combine the shredded chicken, cheddar cheese, cream cheese, mayonnaise, green onions, hot sauce, garlic powder, onion powder, salt, and black pepper. Mix until well combined.
Open the package of biscuit dough and separate the biscuits. Flatten each biscuit into a round disc about 1/4 inch thick.
Place a generous tablespoon of the chicken mixture in the center of each biscuit disc. Fold the edges over the filling and pinch to seal tightly.
Arrange the filled buns on the prepared baking sheet, seam side down. Brush the tops with melted butter and sprinkle with dried parsley.
Bake in the preheated oven for 15-20 minutes, or until the buns are golden brown.
Allow to cool for a few minutes before serving. Enjoy warm!
