I was delighted to find a high fiber, whole grain recipe for muffins, which certainly is wholesome and tasty. I probably made way to many changes to rate, but I can attest to the fact that even changing this recipe substantially it makes great muffins. I had sweet potatoes to use up (instead of pumpkin), buttermilk to use up (instead of milk), soft spelt flour (instead of whole wheat), used agave syrup (instead of honey) and Splenda brown sugar blend (instead of brown sugar). Also, I made 15 muffins and baked them for 18 minutes in a convection oven at 350F. So you see why I couldn't rate this, but I would like to say that it is a great basic recipe that still turns out well when substitutions are made.
