01 - Preheat oven to 400°F. Generously grease a 24-cup mini muffin tin with nonstick spray or butter.
02 - In a large mixing bowl, combine the thawed hashbrowns, shredded cheddar cheese, crumbled bacon (if using), 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 mini muffin tin, pressing down 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, then carefully remove each one using a spoon.
06 - Serve warm, garnished with extra chives or alongside sour cream for dipping.
