Preheat oven to 375 °F
Add frozen hashbrowns to a greased 9x13 pan.
Divide 2 Tbsp Butter evenly (into about 8 smaller pieces) and place all over the Hashbrowns.
Bake hashbrowns for 30 minutes at 375 °F
While hashbrowns are baking: Put the eggs in a large mixing bowl, cook and crumble the bacon (add to bowl) and add shredded cheese to bowl.
In a small bowl - mix garlic powder, onion powder, salt, and pepper.
After the hashbrowns have cooked for 30 minutes, use a fork to separate them a little bit (like a little "stir" while they are still in the pan).
Sprinkle the garlic, onion, salt, and pepper evenly over the hashbrowns. (again, give it a little "stir" with the fork)
Pour the egg, bacon, and cheese mixture evenly over the hashbrowns. (and again - a slight "stir" with the fork).
Bake for 30 more minutes at 375 °F
