Mix all dry ingredients in a bowl. Add wet ingredients to the mixing bowl and mix well with a spoon until there are no more dry spots; don't over-mix. Heat a large skillet on medium heat. Lightly spray oil to coat and pour 1/4 cup of pancake batter. When the pancake starts to bubble, you may add your fruit if you wish. When the bubbles settle and the edges begin to set, flip the pancakes. Repeat with the remainder of the batter.
