In a large mixing bowl, combine flour, sugar, baking powder, baking soda, cinnamon, and salt. Whisk until evenly mixed.

In a separate bowl, whisk together buttermilk, egg, melted butter, and vanilla until smooth.

Pour wet ingredients into the dry mixture and fold gently until just combined. Let the batter rest for 5 minutes.

Heat a nonstick skillet over medium heat, greasing lightly. Test by dropping water onto the skillet—if it dances, it's ready.

Pour ¼ cup of batter for each pancake. Cook until bubbles form and edges set, about 2-3 minutes. Flip and cook an additional 1-2 minutes.

Keep pancakes warm in a 200°F oven until serving. Drizzle with maple syrup or top with fresh berries.
