Preheat your oven to 350 degrees F (175 degrees C). Grease a 9-inch round cake pan with butter or cooking spray.
In a medium bowl, whisk together the egg yolks, flour, baking powder, sugar, butter, milk, salt, and vanilla extract until smooth.
In a separate bowl, beat the egg whites with an electric mixer until stiff peaks form. Gently fold the egg whites into the egg yolk mixture until just combined.
Pour the batter into the prepared pan and bake for 15 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.
Remove the pancake from the oven and let cool for 5 minutes before serving.
