01 - Preheat oven to 400°F. Generously grease a 24-cup mini muffin tin with nonstick cooking spray or butter.
02 - In a large mixing bowl, combine the thawed and dried hashbrowns, shredded cheddar cheese, crumbled bacon (if using), chopped green onions, chives, eggs, sour cream, garlic powder, onion powder, salt, and pepper. Stir until all ingredients are evenly distributed.
03 - Spoon the mixture evenly into each cup of the prepared muffin tin, pressing down gently with the back of a spoon to compact each portion firmly.
04 - Bake for 20 to 25 minutes, or until the tops are golden brown and the edges are crispy.
05 - Allow the bites to cool in the pan for 5 minutes. Carefully loosen and remove each bite using a spoon or small spatula.
06 - Serve warm, garnished with additional chives or alongside sour cream for dipping.
