This is from Food Network's low carb chef, George Stella, and I found it in Low Carb Living Magazine. I liked these because they rose (I was afraid they wouldn't - I can't even get ordinary muffins to rise!), and the banana extract overshadows the soy flavor, which is a very good thing. These are best fresh out of the oven, but are still good for the first couple of days. The magazine says that each muffin is 8.5 net grams carb & 8.1 grams protein.
