In a bowl, add the flour, sugar, baking powder, baking soda, and salt. Whisk together to combine.
In a different bowl, combine buttermilk, vanilla, ground cinnamon and egg. Whisk to combine. Drizzle in melted butter while whisking.
Slowly pour the wet ingredients into the dry ingredients, whisking to mix together just until combined.
Use a 1/4 or 1/3 cup measuring cup to scoop to pour the pancake batter onto a preheated griddle or skillet coated with butter.
Let the pancake cook about 2-3 minutes. You'll notice bubbles popping up on the surface of the pancake and the edges beginning to look set. Carefully flip the pancake over and ook another 2 minutes on the other side.
You can place the pancakes on a baking sheet and keep it in a low heat oven (175-200 degrees), until you're ready to serve. Serves 4.
