Preparation Steps

• In a bowl, whisk together the flour, baking powder, salt, and sugar.
• In a separate bowl, beat the egg whites until stiff peaks form. Set aside.
• In a third bowl, whisk the milk, egg yolks, and vanilla extract. Stir in the melted butter.
• Combine the milk mixture with the dry ingredients and mix until just combined. Gently fold in the beaten egg whites.
• Heat a large non-stick skillet over low heat and lightly coat with butter. Pour 1/4 cup of batter for each pancake and cook until bubbles form on the surface.
• Flip the pancakes and cook for an additional 2-3 minutes until golden brown.
