In a large mixing bowl, whisk together the all-purpose flour, sugar, baking powder, baking soda, ground cinnamon, and salt until blended.

In a separate bowl, whisk the buttermilk, egg, melted butter, and vanilla extract until combined.

Gently fold the wet mixture into the dry ingredients until just combined; a few lumps are fine.

Let the batter rest for about 5 minutes.

Preheat a nonstick skillet or griddle over medium heat.

Pour about ¼ cup of batter onto the skillet for each pancake and cook until bubbles form on the surface, about 2-3 minutes.

Flip each pancake and cook for another 1-2 minutes until golden brown.

Serve warm with your favorite toppings.
