As part of our on-going effort to eat healthier, I've been making a big batch of these muffins on the weekend and then dividing them up and freezing them for us to eat on all through the week. I found this recipe at Farmgirl Fare sometime last winter and think it is the best one ever. I will admit to changing the recipe a little, mainly because I don't have something on hand. Sometimes I add raisins, sometimes cranberries, sometimes both. Occasionally, I will use just a dollop of sour cream in addition to the yogurt and once I even used buttermilk instead of plain milk. It seems to be fairly bomb-proof, as recipes go. These days, I'm mixing up the dry ingredients in zip-lock bags, listing the wet ingredients on the outside of the bag with a waterproof marker pen and storing them in the freezer. I don't even have to look for the recipe that way. If you eat one of these muffins every day, you will never have to worry about getting enough fiber in your diet (if you know what I mean!).
