Combine flour, sugar, baking powder, baking soda, salt, and optional dash of cinnamon in a mixing bowl.
Separate the egg.
In a small bowl, combine the egg yolk, oil, vanilla, and milk.
Pour over the dry ingredients and mix with a fork until lumps are gone.
In another bowl beat the egg white until stiff.
Gently fold the egg whites into the pancake batter with a silicone spatula.
Heat a skillet over medium heat.
Put a ⅓ of a cup of batter onto a hot skillet and cook until golden. (Watch for small bubbles to come up and the edges to look a little more firm.) Flip and cook the other side.
Serve with toppings of choice.
Notes
Buttermilk Substitute: use regular milk or almond milk, decreasing amount by 2 tablespoons. Add a scant tablespoon of vinegar or lemon juice and let stand for 5 minutes.
