01 - In a large bowl, whisk together the flour, sugar, baking powder, and salt until evenly blended.
02 - In a separate bowl, whisk the milk, eggs, melted butter, and vanilla extract until well combined and smooth.
03 - Pour the wet ingredients into the dry ingredients and gently mix until just combined. Do not overmix; a few small lumps are acceptable.
04 - Preheat a non-stick skillet or griddle over medium heat and lightly grease with additional butter.
05 - Pour 1/4 cup of batter per pancake onto the skillet. Use a spoon to shape into hearts or use a greased heart-shaped mold. Cook until bubbles appear on the surface and edges look set, about 2 minutes. Flip and cook 1–2 minutes longer until golden brown.
06 - Transfer cooked pancakes to serving plates. Top with sliced strawberries, a dusting of powdered sugar, and whipped cream if desired. Serve immediately with maple syrup.
