In a large bowl, mix together the flour, sugar, baking powder, baking soda and salt.
In a medium bowl, beat the egg until the whites and yolk are combined. Add the buttermilk and oil and stir to combine.
Add the wet ingredients to the dry ingredients and whisk to combine. For best results, let the batter rest 10 minutes before making pancakes.
Then place a griddle or large frying pan over medium heat. Spray with cooking spray.
Dollop the batter in 1/4 cup amounts per pancake. When the tops are covered with small bursting bubbles, flip the pancakes and cook the other sides to golden brown.
This recipe makes eight 5-inch pancakes.
