I had some frozen bananas that I wanted to make muffins with, but wanted to add some bran to make them more breakfasty. So I searched online and found a recipe on allrecipes.com. And so that I didn't lose it I pinned it too.
I didn't use walnuts in mine, but substituted chocolate chips instead.
Although they were tasty and turned out pretty well, they were a little too greasy!
Next time I think I would use less butter than called for, but I would definitely make them again!
