Preparation Steps

• Preheat the waffle iron according to the manufacturer's directions.
• In a large bowl, whisk together flour, baking powder, sugar, and salt.
• In a small bowl, whisk together egg yolks, milk, melted butter, and vanilla extract. Set aside.
• In a separate medium bowl, beat egg whites with a mixer on medium-high speed until stiff peaks form.
• Add the egg yolk mixture to the dry ingredients and stir to combine. Gently fold in the beaten egg whites.
• Pour by large spoonfuls onto the preheated waffle iron, filling until most of the wells are covered. Close the lid and cook for about 3-5 minutes, or until golden brown.
