Hi friends, here is the recipe you’ve all been waiting for: Banana Oat Chocolate Chunk Muffins! I am just so excited to FINALLY be posting this recipe–mostly because I’ve baked these muffins like a hundred times and the recipe is too good not to be shared with the people I love!
Why This Recipe is Amazing:
It’s made with ingredients you already have.
Besides the fact that these Banana Oat Chocolate Chunk Muffins are amazingly moist and delicious, one of the best things about this recipe is that it’s made with ingredients you probably have sitting in your pantry.
Bananas? Check.
Flour? Check.
Oats? Check.
Chocolate Chips? Yup. (Um…always!)
If you live in the beautiful continent of North America, there’s nothing foreign about this recipe.
It’s the perfect way to use up your overripe bananas!
I used to think that a brown banana was no good, that it was rotten and past its prime. NO NO NO! Don’t even think about throwing those weird lookin’ long brown things away. If you didn’t get a chance to eat up your bananas while they were ripe and don’t have the time to bake with them at this very moment, just toss them in the freezer!
(I mean…some people are a little more organized, but I literally find myself tossing them in my freezer, Ha!)
Overripe bananas freeze so well! And when you’re ready to use them, place them on a plate and let them thaw to room temperature for a couple of hours. Because you are gonna want to use them for this recipe–overripe bananas give the best flavour!
And honestly, how many of us have like 20 bananas sitting in our freezers right now? Haha! We need to do some baking with those babies!
No electric mixer required!
All you need to whip up a batch of these Banana Oat Chocolate Chunk Muffins is a couple of bowls and a wooden spoon (and a plate and fork to mash your bananas). This is a major reason why I LOVE to bake muffins because they’re super fast, easy, and of course the clean-up is quick too.
They freeze really well.
I love having muffins stocked away in my freezer because they make the perfect quick breakfast. You’ll find me almost always doubling a recipe for this very reason, so that I can have extras to keep in the freezer!
For uber-quick thawing, just unwrap them, place them on a paper towel and let them go in the microwave for a few seconds. Breakfast is served, my friends!
Baking these Banana Oat Chocolate Chunk Muffins
Mash those bananas!
The first thing you want to make sure of is that your overripe bananas are thawed and ready to be mashed. It really depends on the size of your bananas, but for this recipe I can use anywhere between 2 and 3 bananas. Just mash ’em on a plate with a fork and fill a 1-cup measuring cup as you go. And why not go ahead and make yourself a smoothie with any leftovers you may have? 😉
To bake standard size muffins or mini muffins…
THAT is the question and just another reason why I love this recipe–you can bake regular size muffins or MINI muffins (mini muffins are so fun)!! I actually like to do half and half: bake 6 standard size muffins, and 24 mini muffins. It’s the best of both worlds.
I find that standard size muffins are perfect for eating in the comfort of your own home, for when you need a substantial breakfast. Whereas the mini muffins are perfect to just pop in your mouth for breakfast’ and snacks on the go.
Mini muffins are also great to bring to special events like potlucks at church, or bridal showers/baby showers–where guests just need a tiny little taste of something dainty-er.
Because of their obvious size difference these different sized Banana Oat Chocolate Chunk Muffins require different baking times (which is all in the recipe below, no worries). If you decide to bake both mini and standard size, because the baking temperature is the same you can bake them in the oven together on the same rack; just take the mini muffins out after 10 minutes of baking, and leave the regular muffins in longer.
The secret to beautiful looking muffins:
So, after you’ve gently folded your muffin batter together, I say folded because you never want to overmix your muffins (this results in a dense and tough texture), divide your batter into the greased muffin tins. I don’t use paper baking cups for this recipe, as I find that these muffins come off really easily from the tin itself, but feel free to use them!
Unlike cupcake batter, you’ll want to fill your muffin tins right to the top. These muffins just rise and take shape so beautifully!
You guys, this is the secret to beautiful looking muffins: sprinkle reserved (or extra) oats, chopped nuts, and chopped chocolate chunks on top of the muffin batter. And then bake! You’ll be surprised at how much better muffins look when you can see the ingredients that make these muffins taste so good, sitting right on top!
I almost always do this fancy trick with any cookies that I bake, such as my Peanut Butter Oatmeal Cookies with chocolate chunks and M&Ms! Seriously guys, do this and take pictures so I can see your beautiful creations! 🙂

Fellow Bakers and Food Photographers:
If you’re wondering how I styled these Banana Oat Chocolate Chunk Muffins to be photographed, I wrote a blog post all about it here:

I am not exaggerating when I say I was in heaven while eating these. I followed everything to a T and they could not have been more perfect. Not overly sweet, which I am all for. This is so great! Quick little pick-me up for the week. Thank you so much for this!!! I will be making this again very soon.
Absolutely divine! Moist, not overly sweet, quick and easy to make. Thank you very much. All the way from Aotearoa.👌👍🏼😀
I doubled the recipe and made 30 small and 16 standard. Delicious. Will definitely make again.
Best tasting muffins I ever made. I did change a couple ingredients, whole wheat flour, olive oil and regular size chocolate chips. I did use walnuts . Very moist and tasty.
These are my new favourite muffins. I absolutely loved the texture and the taste! I am a fan of muffins and always seem to have extra bananas. I did not have walnuts so I added 1/4 cup of pumpkin seeds and 1/2 cup of All Bran cereal for the crunch. Your food photography is beautiful! I am looking forward to trying more of your recipes.
Great recipe! I made small adjustments to make the muffins even healthier: 1/8 cup sugar (instead of 1/2 cup), 3 bananas (instead of 2) to fill in the sugar gap, 1/4 hemp seeds, and 1 cup AP flour + 1/2 cup oat flour combo (instead of 1.5 cups of just AP flour). Turned out great!
Hi, love the simplicity of this recipe!
Unfortunately I only got 34 Mimi muffins not 48 as stated. I always make minis as they are better suited for my grandson.
Regardless, they are supper yummy.
I just made these for breakfast. I ended up having enough batter to make 16 muffins. They are delicious! The oats don’t give too much of an oatmeal-y taste to the muffins, and that’s okay! They are more like banana bread with texture and extra fiber. Haha. I used mini chocolate chips in large muffin tins. This recipe is great to make lots of leftovers for breakfast. Thank you!
