01 - Preheat your heart-shaped waffle iron according to the manufacturer's instructions. Lightly grease the surface with melted butter or nonstick cooking spray to ensure easy release.
02 - In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, baking powder, and salt until thoroughly combined.
03 - In a separate bowl, beat the eggs until frothy. Add the milk, melted butter, and vanilla extract, whisking to incorporate fully.
04 - Pour the wet ingredients into the dry mixture. Stir gently with a spatula or whisk just until combined—do not overmix. Small lumps in the batter are acceptable and will produce tender waffles.
05 - Ladle approximately 1/2 cup of batter onto the preheated waffle iron for each waffle, adjusting based on your iron's capacity. Close the lid and cook for 3 to 5 minutes until golden brown and crispy.
06 - Remove cooked waffles carefully and place them on a wire rack or warm oven (200°F) to maintain crispness while you repeat with the remaining batter.
07 - Arrange two heart-shaped waffles on each plate. Distribute the fresh strawberries, blueberries, and raspberries evenly over the waffles. Dust generously with powdered sugar, drizzle with maple syrup or honey if desired, and garnish with fresh mint leaves.
