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 combined.
03 - In a separate bowl, combine the all-purpose flour, sugar, baking powder, baking soda, and salt.
04 - Add the dry ingredients to the wet ingredients, mixing gently just until incorporated. Do not overmix; a few small lumps are acceptable.

06 - Pour approximately 1/3 cup of batter per waffle into the preheated iron. Cook until golden brown and crisp, typically 3-5 minutes per batch.
