Separate the eggs into two bowls (yolks in one, whites in another).
In the yolk bowl, whisk together egg yolks, milk, vanilla extract, and 1 tbsp sugar until smooth.
Add flour, baking powder, and salt to the yolk mixture and whisk until thick and smooth.
Beat the egg whites until foamy, then gradually add the remaining 2 tbsp sugar and beat until stiff, glossy peaks form.
Fold one scoop of meringue into the yolk batter to loosen it, then gently fold in the remaining meringue in batches without overmixing.
Heat a nonstick pan on low heat and lightly grease with butter or oil.
Spoon or pipe tall mounds of batter into the pan, stacking batter to build height.
Add 1 tbsp water to an empty spot in the pan, cover with a lid, and cook for 4 to 5 minutes on low heat.
Carefully flip the pancakes, add another 1 tbsp water, cover again, and cook for 4 to 5 minutes more until cooked through.
Serve immediately with your favorite toppings.
