Tender and moist Peanut Butter Muffins are possible with just a scoop of sour cream and a couple of bananas.
These muffins are moist and sweet and absolutely perfect for a breakfast treat, an afternoon snack, or even for dessert.

Peanut Butter Banana Muffins
After numerous attempts to find a perfectly moist peanut butter muffin in the past, I finally found the secret ingredient in my friend Jenny’s Healthier Banana Peanut Butter Muffins.
These muffins are adapted from her recipe and thanks to the addition of a banana, they turn out wonderfully every single time we make them.
We’ve been enjoying these Peanut Butter Banana Muffins on a regular basis ever since my youngest son was born. (That’s over 10 years ago now! Wow.)
The bananas don’t add an overwhelming banana flavor, but the moisture they provide for these muffins is priceless.
The sour cream and the banana help create a very moist muffin that freezes quite well and as an added bonus they reheat beautifully at a later date.

Peanut Butter Chocolate Chip Muffins
These are the first Peanut Butter Muffins I have found that freeze well, without drying out. That is a huge success in my book!
While I love them best with chocolate chips, they’re also terrific without the chocolate!
We love having muffins tucked into the freezer for mornings when there isn’t a lot of time for breakfast. They reheat beautifully in about 30 seconds.
If you are out of liners try this trick to make your own in no time at all.

Along with these muffins, the Hawaiian Muffins are kid favorites every time I make them.
Don’t forget to try pumpkin muffins, blueberry bran muffins, and zucchini muffins too!

Kitchen Tip: I use this muffin tin, these liners (best deal ever!), and this scoop to make this recipe.

Fresh Garden says
Absolutely fantastic!
Thanks for sharing, you're wonderful! 🙂
Susan from Food Blogga says
Numerous attempts? Considering that they have pb, chocolate chips and bananas in them, that couldn't have been too hard on you. 😉
Barefeet In The Kitchen says
Yeah, it was torture. 😉
Lynn says
Looks amazing! I wanted to make these in mini muffins tin for a snack to preschool class. Do they rise too much? I wanted to know if I should fill the mini cups all the way or just half way.
Thanks!
Mary says
I'd fill them about 3/4 of the way. They have a pretty good rise. Enjoy!
Peggy says
Is wheat flour required?
Mary says
Not at all. Feel free to substitute all purpose flour. Enjoy!
Char Steen says
Going to make these today with the ripe bananas that I didn't know what to do with. Thank You, Mary & Happy New Year !!!

Googled to find a nutritious banana muffin recipe & found this recipe! I doubled the recipe, and it came out fine.
It’s also a very versatile recipe, and accommodated a number of substitutions for things I had on hand!
I used the following substitutions:
Coconut oil instead of butter
1/2 cup rolled oats for 1/2 cup flour
organic whole milk plain yogurt for sour cream
I used 1/2 the amount of chocolate chips called for, and it was sufficient (even for me, and I am a confessed choco-holic)
I think methods matter, so I recommend:
Mash the bananas in a bowl. In separate bowl, cream the butter/oil & peanut butter. Add sugar, then add the beaten eggs.
In a separate bowl, mix the dairy with the baking soda & set aside for a couple of minutes (because it’s cool to see the chemical reaction. )
Then, add all these wet ingredients together.
Sift in the flour, salt & baking powder until well mixed.
Lastly, I added oats, then the chocolate chips.
Since it didn’t specify (but the photo showed a cupcake paper) I tried both using paper muffin liners & greased muffin pans.
Greased muffin pans resulted a thin crispiness on the outside & moist inside
Paper liners took a little longer to bake & were very moist, but left a good amount of the muffin sticking to the paper (although I confess, I didn’t wait for the muffins to cool).
I prefer the greased muffin, then place it in a paper liner afterward, if necessary to serve. Since I made these for a group function, I placed them in the paper liners. At home, I don’t think I’d use the paper. Also, oddly, the peanut butter melted through the paper in a couple of paper cups, leaving a puddle in the bottom of the pan. These were name brand cupcake liners – Betty Crocker, not some off brand, so I don’t recommend the paper.
Other substitutions I intend to try:
dried cranberries, goji berries, cacao nibs, chia seeds, nuts, fresh blueberries or cranberries, lemon/orange rind. All of these would pair well with banana. (Some would compete with peanut butter, so I’d omit that ingredient.)
Beth says
Any substitute for the bananas in this recipe???
Mary Younkin says
Normally, you could sub applesauce for the bananas, probably about 3/4 cup for 2 small bananas worth, but I haven’t tried that in this particular recipe and I’m not sure how the flavors will work with that, Beth.
Allison Hoffman says
Every time I click on a recipe, I find your picture! We must have similar taste buds because all of the recipes look so inviting and makes me anxious to try them!
Mary Younkin says
I’m so glad that you’re enjoying the recipes, Allison!
Diane Young Decker says
Have you tried this with gluten-free flour of any kind? What worked or didn’t. GF muffins are notorious for being dry, but with sour cream AND bananas, perhaps this one would be more moist.
Mary Younkin says
I don’t have a GF variation for this recipe, Diane. I’m guessing it will work nicely though.
Kate says
I’m so excited to try these muffins! In my opinion, it doesn’t get much better than peanut butter, chocolate and banana all wrapped up in a mini moist cake! Thank you for sharing!
Mary Younkin says
I hope you love them too, Kate!
mpotter says
I am a fan! I eat PBB sandwiches a lot!! Can you please clarify if this is JIF styled peanut butter, or natural peanut butter?
Thanks so much.
Mary Younkin says
I use Jif peanut butter myself.
Monica says
I just made these and although tasty, I do not get a strong taste of peanut butter and almost no banana flavor. I only put half the amount of chocolate chips but that is pretty much the main flavor I am getting. I made a few with no chips and the peanut butter comes through but still not much banana. But easy and quick!
