Add flour, sugar, baking powder, baking soda, salt, and cinnamon to a mixing bowl.

In a separate bowl, whisk together buttermilk, vanilla and egg. Melt butter, cool slightly, and gradually add to wet ingredients.

Pour wet ingredients into dry and whisk together until smooth. Allow batter to rest for 1-2 minutes.

Spray a griddle with cooking spray and heat over medium. Once hot, add 1/4 cup of batter per each pancake. Once the pancake has begun to bubble, flip and cook for 1-2 minutes longer until cooked through. Remove from heat and continue with remaining batter until all has been used.

Top with maple syrup and serve with orange wedges on the side.
