**Preheat the Oven:**
Preheat your oven to 375°F (190°C) and grease an 8x8-inch baking dish or individual ramekins with butter.
**Whisk the Eggs:**
In a mixing bowl, whisk the eggs until smooth and well combined.
**Mix the Ingredients:**
Stir in the cottage cheese, shredded cheddar cheese, green onions, garlic powder, salt, and black pepper. Mix until evenly combined.
**Pour into Dish:**
Pour the egg mixture into the prepared baking dish or divide it evenly among the ramekins.
**Bake:**
Bake for 25-30 minutes, or until the eggs are set and the top is slightly golden. If using ramekins, check for doneness around 20 minutes.
**Serve:**
Remove from the oven and let cool for a few minutes before serving. Garnish with extra green onions if desired.
