Preheat your oven to 350ºF and grease a 9x13-inch casserole dish.
Add the eggs to a large bowl and beat with an electric mixer until the eggs are light and foamy, about 2-3 minutes.
12 eggs
Add the baking powder, flour, and salt to the bowl and beat slowly until smooth.
½ cup flour, 1½ teaspoons baking powder, ¾ teaspoon sea salt
Add the shredded cheeses, cottage cheese, melted butter, and diced chilies and stir.
2 cups cheddar cheese, 1 cup Monterey Jack cheese, 2 cups cottage cheese, 6 Tablespoons butter, 8 ounces green chilies
Pour the batter into the prepared casserole dish and bake for 35 minutes. The top of the casserole and the edges will be golden brown. The center will feel firm when touched and not liquid.
Let the casserole cool for about 5 minutes before slicing and serving.
