01 - Preheat oven to 400°F. Generously spray a 24-cup mini muffin tin with nonstick cooking spray.
02 - In a large bowl, combine the thawed hashbrowns, shredded cheddar, sour cream, melted butter, crumbled bacon, green onions, garlic powder, onion powder, salt, pepper, and egg. Mix thoroughly until all ingredients are evenly distributed.
03 - Spoon the mixture evenly into the prepared mini muffin tin. Gently press down the filling with a spoon to pack it tightly into each cup.
04 - Bake for 20 to 25 minutes, or until the tops are golden brown and the edges are crispy.
05 - Let the bites cool in the tin for 3 to 5 minutes before removing. Serve warm with optional toppings like sour cream or extra green onions.
