01 - Preheat the waffle iron in accordance with the manufacturer's instructions to ensure even cooking.
02 - Whisk together the all-purpose flour, granulated sugar, baking powder, and salt in a large mixing bowl.
03 - In a separate bowl, whisk eggs, milk, melted unsalted butter, and vanilla extract until thoroughly combined.
04 - Pour wet mixture into the dry ingredients and gently mix until just blended; do not overmix as some lumps are acceptable.
05 - Carefully fold diced strawberries into the waffle batter, distributing them evenly.
06 - Lightly grease the preheated waffle iron with a small amount of butter. Spoon the prepared batter onto the iron, following the suggested quantity guidelines of the appliance. Close the lid and cook for 3 to 5 minutes, or until waffles are golden brown and crisp.
07 - Serve waffles immediately while warm. Top with whipped cream or yogurt, additional diced or sliced strawberries, and maple syrup or honey as desired.
