01 - Preheat the waffle iron according to the manufacturer's instructions.
02 - Whisk flour, granulated sugar, baking powder, and salt together in a large mixing bowl.
03 - In a separate bowl, whisk eggs, milk, melted butter, and vanilla extract until thoroughly blended.
04 - Pour the wet ingredients into the dry mixture. Gently mix until just combined; avoid overmixing as some lumps are acceptable.
05 - Carefully fold the diced strawberries into the batter using a spatula.
06 - Lightly grease the preheated waffle iron with melted butter. Pour an appropriate portion of batter onto the hot plates following the waffle iron’s guidelines. 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, sliced strawberries, and maple syrup or honey as desired.
