01 - Preheat your oven to 400°F. Grease a 24-cup mini muffin tin thoroughly.
02 - In a large mixing bowl, combine the thawed hashbrowns, cheddar cheese, crumbled bacon (if using), green onions, chives, eggs, sour cream, garlic powder, onion powder, salt, and pepper. Mix until thoroughly incorporated.
03 - Spoon the mixture evenly into the prepared muffin tin, pressing down gently to compact each portion.
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 them using a spoon, then serve warm. Garnish with extra chives or serve with a side of sour cream if desired.
