I'm into banana recipes lately. I just got done making and eating one of these, and I knew I would have to sit down and share it. Right now, I'm anticipating tomorrow when I will have another one. This is another recipe by Joanna Lund. The diabetic exchanges per serving are: 1 1/2 Starch, 1/2 Fruit and 1/2 Fat. Each serving (muffin) is only 137 calories.
