01 - Preheat your heart-shaped waffle iron according to the manufacturer's instructions.
02 - In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt until well combined.
03 - In a separate bowl, beat the eggs, then add the milk, melted butter, and vanilla extract. Whisk until smooth and fully incorporated.
04 - Pour the wet ingredients into the dry ingredients and gently fold until just combined. Do not overmix; small lumps are acceptable and will yield tender waffles.
05 - Lightly grease the preheated waffle iron. Pour approximately 1/2 cup of batter per waffle, adjusting based on iron size. Cook until golden and crisp, about 3–5 minutes per batch.
06 - While waffles cook, whip the heavy cream with powdered sugar and vanilla extract until soft peaks form.
07 - Wash and pat dry the berries. Hull and slice strawberries if using; leave smaller berries whole.
08 - Plate warm heart-shaped waffles topped with a generous dollop of whipped cream and a handful of mixed berries. Drizzle with maple syrup and garnish with mint leaves or a dusting of powdered sugar if desired.
