01 - In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.
02 - In a separate bowl, combine the buttermilk, egg, melted butter, lemon zest, lemon juice, and vanilla extract. Whisk until well blended.
03 - Pour the wet mixture into the dry ingredients and stir gently until just combined; small lumps are acceptable. Avoid overmixing.
04 - Heat a nonstick skillet or griddle over medium heat and lightly grease with butter or oil.
05 - Pour 1/4 cup of batter per pancake onto the hot skillet. Cook for 2 to 3 minutes until bubbles form on the surface and edges appear set.
06 - Turn pancakes over and cook an additional 1 to 2 minutes until golden brown and cooked through. Repeat with remaining batter.
07 - Serve warm, optionally topped with maple syrup, fresh berries, extra lemon zest, or a dusting of powdered sugar.
