Preheat waffle iron. Spray with cooking spray or brush with oil.
In a large bowl, combine flour, baking powder, baking soda, cinnamon, salt, and granulated sugar by whisking together.
Stir in vegetable oil, lemon juice and sparkling water until combined. Batter will be thick.
Stir in chocolate chips.
Add 1/2 cup of the batter to the middle of the waffle iron. Close the lid and cook for 5-6 minutes or until the waffle is lightly browned and crispy. Set aside or keep warm in the oven. Brush the waffle iron with more oil in between each use to prevent sticking.
