I have a ton of bananas in my freezer (I can't stand them once they get over-ripe, but they're great for banana bread!) Before I got pregnant I kept meaning to make them into bread or muffins and never got around to it. Then once I DID get pregnant I actively avoided making any, because banana bread is a weakness of mine and I have a hard time saying no even without the added hormones. Well, I was talking to one of my students this week about my ridiculous stash, and she has been begging me to make banana chocolate-chip muffins to bring for the class. Today is the 100th day of kindergarten, so I figured I'd make the muffins and bring them as a special treat, which would help me unload some of those bananas taking up space in my freezer, and I could keep a few at home without having so many that I enter the "danger zone." So last night DD and I made them, and had a lot of fun. The recipe I use is pretty healthy--it calls for whole wheat flour, flax meal, rolled oats, just one cup of sugar, 5 bananas, and applesauce in place of oils. One cup of dark chocolate chips, because you just gotta. Recipe made enough for almost 40 muffins!
Well this morning DD threw an absolute fit when it was time for me to leave for work, and we didn't sleep very well last night so I was groggy and not in the mood to put up a fight. So I called in sick to work. 
And now I have all weekend long, and 40 banana chocolate chip muffins in my fridge, whispering my name. I'm sure that by Sunday night it will no longer be a whisper...
Not that there's anything wrong with your muffin plan 
but just another idea for future reference, if you cut up the frozen bananas into somewhat smaller pieces (maybe quarters) then put them in a food processor they will turn into a great banana gelato.
