    Fabulous...only thing I changed was omitted walnuts and used chopped nuts instead. Everyone loved them 😋  -  05 Oct 2013


    While very good, I think the butter could be reduced to 1/4-1/3 cup-I had the same experience as another reviewer who commented that butter had actually seeped through the paper liners and was visible in the pan after the muffins were removed. Good banana flavor, hearty texture because of the oats and nuts, and a crunchy brown sugar topping. Muffin tin sizes vary, so you may get more or less than 12 muffins--just remember to fill the muffin cups 3/4 full.  -  29 May 2008  (Review from Allrecipes US | Canada)


    It really bugs me it when people review recipes after making a ton of changes but because a lot of swaps are suggested in reviews for this particular muffin, I will say this: these were good the way I made them after reading through the reviews but I suspect they would have been better had I not swapped half the butter for applesauce, exchanged for wheat flour and subbed low-fat yogurt for the sour cream. A solid three or four with the subs, I have no trouble believing they'd be 5 star if left alone.  -  19 Feb 2008  (Review from Allrecipes US | Canada)
