Preheat your oven to 400°F (200°C) and grease a muffin tin with cooking spray or oil.
In a large bowl, combine the thawed hash browns and shredded cheddar cheese. Mix well.
Press the hash brown mixture into the bottom and up the sides of each muffin cup to form a crust.
In another bowl, whisk together the eggs, milk, salt, pepper, garlic powder, and onion powder until well combined.
Stir in the chopped bacon, then pour the egg mixture evenly into each hash brown crust.
Bake in the preheated oven for 20-25 minutes, or until the egg is set and the edges are golden brown.
Allow the muffins to cool for a few minutes before carefully removing them from the tin.
