01 - Preheat the waffle iron according to the manufacturer's specifications.
02 - In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, baking powder, and salt until thoroughly blended.
03 - In a separate bowl, whisk the eggs, whole milk, melted unsalted butter, and vanilla extract until the mixture is smooth and fully integrated.
04 - Pour the wet mixture into the dry ingredients and gently fold together until just combined; avoid overmixing to maintain tenderness. Batter may remain slightly lumpy.
05 - Carefully fold the diced strawberries into the batter, distributing them evenly.
06 - Lightly grease the preheated waffle iron with melted butter. Spoon an appropriate portion of batter into the center and close the iron. Cook for 3 to 5 minutes, or until the waffles are golden brown and crisp.
07 - Transfer waffles to plates and serve immediately with desired toppings such as whipped cream, sliced strawberries, and maple syrup or honey.
