You have a choice in what kind of flour you use. These are already low-fat cookies, but if you want to make them even healthier, you can make them with whole wheat pastry flour. I would've, normally, but I don't have any right now and I can't run to the grocery store and even if I did I really doubt I'd find any there. So I used all purpose flour, but you can also use a mix of apf and whole wheat flour. Or sub half a cup with almond flour, which makes these cookies chewier and nuttier and altogether even more divine. You will need to puree the bananas for these cookies--don't just mash them the way you would for a banana bread because you don't want any lumps in here. Just a quick turn in the blender or food processor works. Like I said earlier, you can use white or regular chocolate chips. Or leave out the chocolate and stir in some nuts, like walnut, pecans or blanched or chopped almonds. If you have Halloween candy you hid from your kids after you realized they were staying up half the night because they were eating their weight in chocolate (just sayin'), this is a good time to dig it out. You can stir in candies like Skittles whole, or even chop up larger pieces of candy into smaller bits and toss them into the batter. Get creative, there's never been a better time
