01 - Preheat the waffle iron according to the manufacturer's directions.
02 - In a large bowl, whisk together all-purpose flour, granulated sugar, baking powder, and salt.
03 - In a separate bowl, whisk the eggs, milk, melted unsalted butter, and vanilla extract until uniformly blended.
04 - Pour the wet mixture into the dry ingredients and stir gently until incorporated. Avoid overmixing; a few lumps are expected.
05 - Gently fold the diced strawberries into the batter.
06 - Lightly grease the hot waffle iron with butter. Spoon the appropriate amount of batter onto the iron and close the lid. Cook each waffle until golden brown and crisp, approximately 3 to 5 minutes per batch.
07 - Serve warm waffles with whipped cream, extra sliced strawberries, and maple syrup or honey as desired.
