01 - Preheat your waffle iron according to the manufacturer's instructions.
02 - In a medium bowl, whisk together the Greek yogurt, eggs, milk, melted butter, and vanilla extract until smooth and well incorporated.
03 - In a separate bowl, combine the flour, sugar, baking powder, baking soda, and salt, stirring to ensure even distribution of leavening agents.
04 - Add the dry ingredients to the wet ingredients, folding gently with a spatula just until incorporated. Avoid overmixing; small lumps are acceptable and will result in lighter waffles.
05 - Lightly grease the preheated waffle iron with melted butter or cooking spray to prevent sticking.
06 - Pour approximately 1/3 cup of batter into the center of the waffle iron, adjusting quantity based on iron size. Cook until golden brown and crisp, typically 3-5 minutes per batch.
07 - Serve immediately while warm, topped with fresh berries, honey, or pure maple syrup as desired.
