This comes from my Hungry Girl cookbook, these are my personal changes - i prefer slicing the apples before baking, and i also use Gala apples (since that's what I normally eat), and i used enough soda to cover the apples (more than 12 oz.), so adapt to your preferences :-)
This is a recipe from Kashi Go Lean Crunch Cereal, healthy and yummy - I'm officially a fan. I personally use vanilla soy milk and egg whites
Note: preparation time allows the 1 hour to refrigerate batter.
