Preheat oven to 350°F (175°C) and grease a 2-quart baking dish or four 8-ounce ramekins.
In a large mixing bowl, whisk the eggs until the yolks and whites are fully integrated.
Fold in the cottage cheese, shredded cheddar cheese, sea salt, black pepper, and baking powder.
Stir in the melted butter until the mixture is homogenous.
Pour the egg mixture into the prepared baking dish.
Bake for 25 to 30 minutes, or until the eggs are puffed and the center is just set.
Garnish with minced chives and serve immediately while aerated.
