Heat the oven to 375°F (190°C) and lightly grease or line a baking dish with parchment.
Separate the eggs, placing the yolks and whites in different bowls.
Whisk the milk and flour into the yolks until the mixture is mostly smooth.
Beat the egg whites until stiff peaks form.
Gently fold the whites into the yolk mixture in portions, keeping as much air in the batter as possible.
Pour into the prepared baking dish and spread evenly.
Bake for 30 to 35 minutes, until puffed, golden, and set in the center.
Serve warm with your preferred toppings.
