01 - Whisk together flour, sugar, baking powder, baking soda, and salt in a mixing bowl until thoroughly combined.
02 - In a separate bowl, whisk buttermilk, eggs, melted butter, and vanilla extract until smooth and emulsified.
03 - Pour wet ingredients into dry ingredients and fold gently until just combined. Stop mixing when small lumps remain; overworking will produce tough pancakes.
04 - Combine sliced strawberries with sugar and lemon juice in a small bowl. Set aside to release juices while preparing pancakes.
05 - Place a non-stick skillet or griddle over medium heat. Lightly coat surface with butter to prevent sticking.
06 - Pour approximately 1/4 cup batter per pancake onto the skillet. Use a heart-shaped mold if desired. Cook until surface bubbles form and edges appear set, approximately 2 minutes. Flip and continue cooking for 1 to 2 minutes until golden brown and cooked through.
07 - Continue with remaining batter, adding butter to the skillet as needed between batches.
08 - Stack warm pancakes on plates. Top generously with macerated strawberries, whipped cream, and maple syrup.
