"Yum, yum, yum", said my 8 year old son! This is a great muffin!!! I love that it added a bit of health value to an otherwise unhealthy mix. My bananas were frozen, so I mashed them and let them thaw out for this and another recipe. For the yogurt, all I had was ff strawberry cheesecake, but that apparently was a good thing. Also used finely chopped walnuts, because my family is a big fan! I baked them for a little over the time here, but I made them a bit larger. Will be giving some to my friend when I see him this weekend. He and his daughter love this sort of thing. Thanks so much!
