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 smooth and fully combined.
03 - In a separate bowl, combine the all-purpose flour, sugar, baking powder, baking soda, and salt, whisking to ensure even distribution.
04 - Add the dry ingredients to the wet ingredients, mixing gently with a spatula just until incorporated. Do not overmix; small lumps are acceptable and will result in tender 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 your iron's size. Cook until golden brown and crisp, typically 3-5 minutes per batch.
07 - Serve waffles warm with desired toppings such as fresh berries, honey, maple syrup, or additional Greek yogurt.
