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 homogeneous.
03 - Pour wet ingredients into dry ingredients and fold gently until just combined. Avoid overmixing; small lumps are acceptable and desirable for tender pancakes.
04 - Toss sliced strawberries with sugar and lemon juice in a small bowl. Set aside to macerate while pancakes cook, allowing natural juices to release.
05 - Heat a non-stick skillet or griddle over medium heat. Lightly grease surface with butter, adjusting heat as needed to prevent burning.
06 - Pour approximately 1/4 cup batter per pancake onto skillet. Use heart-shaped mold if desired. Cook until surface bubbles form and edges appear set, about 2 minutes. Flip and cook 1-2 minutes longer until golden brown and fully cooked through.
07 - Repeat with remaining batter, re-greasing skillet as necessary between batches. Maintain consistent medium heat for uniform results.
08 - Plate warm pancakes topped with macerated strawberries and their juices. Add whipped cream if desired and drizzle with maple syrup. Serve immediately while hot.
