Whisk together the dry ingredients, including the flour, baking soda, baking powder, cinnamon, salt, and sugar in a large mixing bowl.
Make a well in the center of the mixture.
Add the applesauce, buttermilk, and canola oil to the well; then stir just until moistened.
Lightly spray a griddle with cooking spray, and heat to a moderate temperature over low to medium heat.
Spoon the pancake batter onto the hot griddle, and cook until the tops are covered with bubbles and the edges turn golden brown.
Flip the pancakes and cook the other side. Cook until the pancakes are golden brown and cooked through.
Serve with butter, warm syrup, or a dusting of powdered sugar.
