My co-workers and I have a little tradition we call Friday Food Day. The title is pretty self-explanatory, but we basically take turns bringing in a treat each Friday. Typically, it is a breakfast item, since we have to be at work earlier than usual on Fridays, and everyone needs a little push to get the day started. However, the bounds of "breakfast" have been stretched on occasion to include red velvet cupcakes and cookies. I'm not one to turn down cream cheese frosting, no matter what time of day it is, but I generally like to fool myself into thinking that my breakfast offers some health benefits. So when my turn came around on a recent Friday, I went searching for a recipe for a somewhat wholesome muffin. I found a winner on one of my favorite food blogs, Smitten Kitchen. These whole wheat apple muffins are nice and moist, with big chunks of apple and some heartiness from the whole grain flour. I used about 1 3/4 cups of peeled and chopped Braeburn apples (they were on sale), and definitely don't skip the brown sugar topping--the sweet, crunchy top is a great contrast to the more virtuous bottom.
