In a large mixing bowl, combine the dry ingredients: all-purpose flour, sugar, baking powder, baking soda, salt, and ground cinnamon. Whisk for about 1-2 minutes until well combined.

In a separate bowl, whisk together the wet ingredients: buttermilk, egg, melted butter, and vanilla extract. Beat until smooth, about 1-2 minutes.

Gently pour the wet mixture into the dry ingredients. Stir just until combined, leaving a few lumps. Let the batter rest for about 5 minutes.

Preheat your skillet or griddle over medium heat for about 5 minutes. Sprinkle a few drops of water to check readiness; they should sizzle.

Ladle approximately ½ cup of batter onto the skillet for each pancake. Cook for 2-3 minutes until bubbles form on the surface.

Carefully flip the pancake and cook for another 1-2 minutes until golden brown. Check for doneness by pressing the center.

Serve warm with syrup, fresh fruit, or whipped cream. Customize as desired.
