I sort of used this recipe but altered it a bit.
I used 4 bananas and added cinnamon (sifted with the flour) and vanilla (mixed into the banana mixture), as was suggested by several people in their reviews. I also folded in about a cup of oats after everything was combined.

They’re very very moist and delicious. Mmm.
I tend to feel that walnuts make most things better… but I didn’t add any this time. It would’ve been good though!
Walnuts + oats = my favorite things to add to stuff, in general.
