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