01 - Preheat oven to 400°F. Coat a 24-cup mini muffin tin generously with nonstick cooking spray.
02 - In a large mixing bowl, combine the thawed hashbrowns, shredded cheddar cheese, sour cream, melted butter, crumbled bacon (if using), green onions, garlic powder, onion powder, salt, black pepper, and egg. Stir until all ingredients are evenly distributed.
03 - Spoon the mixture evenly into each cup of the prepared mini muffin tin, pressing gently to compact and shape each bite.
04 - Bake for 20 to 25 minutes until the tops and edges are golden brown and crispy.
05 - Let the bites rest in the tin for 3 to 5 minutes before carefully removing. Serve warm with additional sour cream or chopped green onions on top.
