01 - In a large bowl, whisk together the flour, sugar, baking powder, and salt until thoroughly incorporated.
02 - In a separate bowl, whisk the milk, eggs, melted butter, and vanilla extract until smooth and uniform.
03 - Pour the wet ingredients into the dry ingredients and gently fold until just combined. Avoid overmixing; small lumps are acceptable and will yield tender pancakes.
04 - Heat a non-stick skillet or griddle over medium heat and lightly coat with butter to prevent sticking.
05 - Pour 1/4 cup of batter per pancake onto the skillet. Shape into hearts using the back of a spoon or a greased heart-shaped mold for precision.
06 - Cook until bubbles form across the surface and edges appear set, approximately 2 minutes.
07 - Carefully flip pancakes and cook for an additional 1 to 2 minutes until golden brown and cooked through.
08 - Transfer pancakes to serving plates. Arrange sliced strawberries on top, dust with powdered sugar, add whipped cream if desired, and serve with warm maple syrup.
