01 - Preheat the waffle iron according to the manufacturer's instructions.
02 - In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, baking powder, and salt until evenly combined.
03 - In a separate bowl, whisk together eggs, milk, melted unsalted butter, and vanilla extract until thoroughly blended.
04 - Pour the wet mixture into the flour mixture and stir gently until just combined; a few lumps are acceptable to ensure tender waffles.
05 - Gently fold the diced strawberries into the batter, distributing evenly without overmixing.
06 - Lightly grease the hot waffle iron with butter. Pour the recommended amount of batter onto the center of the waffle iron.
07 - Close the waffle iron and cook until the waffles are golden brown and crisp, typically 3 to 5 minutes per batch, depending on your equipment.
08 - Serve waffles warm, topped with whipped cream, extra sliced strawberries, and maple syrup or honey as desired.
