01 - Whisk together flour, sugar, baking powder, baking soda, and salt in a large mixing bowl until evenly distributed.
02 - In a separate bowl, whisk milk, eggs, melted butter, and vanilla extract until fully blended and smooth.
03 - Pour wet ingredients into dry ingredients. Stir gently with a spatula until just combined; the batter should remain slightly lumpy. Avoid overmixing to prevent tough pancakes.
04 - Heat a nonstick skillet or griddle over medium heat. Lightly grease the surface with butter, using additional butter as needed between batches.
05 - Pour batter into a heart-shaped mold or freeform the shape with a spoon. Cook until bubbles form across the surface and edges appear set, approximately 2 minutes. Flip carefully and cook another 1 to 2 minutes until golden brown.
06 - Continue cooking remaining batter, replenishing butter on the cooking surface as necessary. Keep cooked pancakes warm if desired.
07 - Arrange pancakes on serving plates. Top generously with sliced strawberries, drizzle with maple syrup or honey, and finish with a dusting of powdered sugar or dollop of whipped cream.
