01 - In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt until evenly mixed.
02 - In a separate bowl, whisk together the buttermilk, egg, melted butter, lemon zest, lemon juice, and vanilla extract until smooth.
03 - Pour the wet mixture into the dry ingredients and stir gently just until combined; small lumps are acceptable to avoid overmixing.
04 - Preheat 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 skillet. Cook for 2 to 3 minutes until bubbles form on the surface and the edges appear set.
06 - Flip pancakes and cook for 1 to 2 minutes more until golden brown and cooked through. Repeat with remaining batter.
07 - Serve pancakes warm with maple syrup, fresh berries, additional lemon zest, or a sprinkling of powdered sugar as desired.
