The original recipe is from Bob's Red Mill, however I have tweaked it to be slightly healthier so I am posting here despite the original recipe already being posted a few times on Food.com. My version is higher fiber, lower fat, and lower sugar as well. I actually will eat 3 or 4 of these muffins as a meal replacement and I find that they completely fill me up. And... the best part is that the taste is amazing... just like carrot cake. If you don't mind the calories, try it with a little butter on top.
