01 - Preheat your waffle iron according to the manufacturer's instructions until ready.
02 - In a medium bowl, whisk together the Greek yogurt, eggs, milk, melted butter, and vanilla extract until completely smooth and well combined.
03 - In a separate bowl, combine the all-purpose flour, sugar, baking powder, baking soda, and salt. Whisk to ensure even distribution of leavening agents.
04 - Add the dry ingredients to the wet ingredients. Mix gently using a spatula or whisk just until the flour is incorporated. Stop mixing when a few small lumps remain—overmixing will result in tough 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 (adjust quantity based on your iron's size). Close the lid and cook until golden brown and crisp, typically 3-5 minutes per batch.
07 - Remove waffles carefully and serve immediately while warm. Top with fresh berries, honey, maple syrup, or additional Greek yogurt if desired.
