Start by setting your oven to 375 degrees F (190 degrees C) so it can reach the proper temperature while you prep. A fully preheated oven is crucial for getting the biscuit dough to rise quickly and become flaky.
Grab a medium-sized bowl and toss in your shredded chicken, the Buffalo sauce, and the mozzarella cheese. Stir everything together until the chicken is evenly coated in the sauce and the cheese is well distributed throughout the mix.
Take the biscuits out of the can and separate them, then place them on a clean, flat surface. Use your rolling pin to gently roll each biscuit out until it is about 1/8-inch thick, creating a larger surface area for stuffing.
Spoon about 1/4 cup of the chicken mixture into the center of each flattened biscuit round. Pull the edges of the dough up over the filling and pinch them tightly together to seal the chicken inside securely.
Place each filled biscuit on your ungreased baking sheet, making sure the seam side is facing down. This prevents them from bursting open while they bake and ensures they keep their nice round shape.
Slide the baking sheet into your preheated oven and let them cook for about 15 minutes. You are looking for a deep golden brown color on top and for the biscuits to be hot all the way through.
While they bake, mix the melted butter, parsley, and garlic powder in a small dish. As soon as you pull the biscuits out of the oven, brush this mixture generously over the tops for extra flavor.
Transfer the hot chicken bombs to a serving platter right away while the cheese is still melty. Set out small bowls of blue cheese or ranch dressing alongside them for your guests to dip.
