Apple Brownies

An apple a day keeps the doctor away, right? That's what I kept telling myself while baking these. In my attempt to lead a healthier lifestyle in 2013 I'm trying my hardest to find "healthier" alternatives to my favorite foods.
So for my first "healthy" dessert I present Apple Brownies. In my opinion these brownies resemble an apple pie/cake . It looks and smells like apple pie, and that's mainly because of the cinnamon. Honestly these brownies are so decadent and flavorful and they don't require much ingredients.
