Easy Chocolate Chip Banana Oatmeal Muffins
I’m so happy to share these banana oat muffins with you! I created them for mornings when you want a brownie-level chocolate fix but still want something with real bananas, whole grains, and no refined flour. Oat flour replaces wheat for a tender, naturally gluten-free crumb, ripe bananas add sweetness and moisture, and cocoa powder plus chocolate chips deliver double chocolate flavor in every bite. So yummy!
The key to fudgy texture is using really ripe bananas. Look for ones with brown spots all over the peel because that’s when the starches have converted to sugar and the banana flavor is most concentrated.
These muffins are perfect for kid-friendly breakfasts, lunchbox snacks, or a healthier sweet treat, too.
They freeze beautifully for up to 3 months and microwave back to fresh-baked texture in 20 seconds. And if you love this banana-chocolate combination, my chocolate chip banana bread muffins use a similar one-bowl approach with banana bread flavor, and my flourless double chocolate zucchini muffins bring the same double-chocolate vibes with a “vegetable”hidden veggie” twist.

Testing Tips for Chocolate Banana Oatmeal Muffins
- Use the ripest bananas you can find for sweetest flavor in the final muffins.
- Sift the cocoa powder before adding it to the batter if you can. Cocoa powder is notorious for clumping, and any clumps in the batter become bitter pockets in the finished muffin.
- Use mini chocolate chips instead of regular-size chips for a fun twist. Bonus, they also stay suspended in the batter better and don’t sink to the bottom as easily as larger chips.

Banana Oat Chocolate Muffins (No Flour)
Ingredients
- 2 large eggs
- ¼ cup melted coconut oil (or other neutral flavored oil such as avocado or canola)
- 1 ⅓ cup mashed very-ripe banana
- ⅓ cup pure maple syrup
- 2 teaspoons pure vanilla extract
- 1 ¾ cups oat flour*
- ⅓ cup cocoa powder
- ½ teaspoon baking soda
- ½ teaspoon baking powder
- ¼ teaspoon kosher salt
- ⅓ cup chocolate chips, plus more for topping
Equipment
Instructions
- Heat the oven to 350F.
- In a large bowl, whisk together the eggs, coconut oil, banana, maple syrup, and vanilla extract.
- Add the oat flour, cocoa powder, baking soda, baking powder and salt. Stir gently until just incorporated.
- Add in the chocolate chips and stir to combine.
- Fill each muffin tin section with roughly ¼ cup batter, then bake for 15-20 minutes, or until the edges begin to pull away from the sides and a toothpick comes out clean.
- Allow to cool in the pan for 5 minutes, then cool the rest on a cooling rack.
Notes
- Most chocolate chips include dairy. Be sure to use dairy-free if that’s important to you. I like Enjoy Life brand.
- Skip the chocolate chips to keep this recipe completely refined sugar-free.

Haha! I love the photos of Ellie with her face in the bowl 😊 Trying this recipe soon!
Ashley, the girl loves her some chocolate! Hope you enjoy this one. 🙂
Just tried this recipe this evening, to include grinding my own oat flour. Super easy and amazing. This is definitely more like dessert, but there’s something about dark chocolate and banana that goes so well together. Thanks for sharing.
Jenn, yay, so glad you enjoyed. I agree, these are definitely dessert-worthy! 🙂
Can I use cacao instead of cocoa?
Jane, absolutely! I hope you enjoy. 🙂
great thanks!
will I need to change anything else in the recipe? or can I just do a straight substitution?
Jane, it should just work as a straight substitution.
What would be a good substitute for coconut oil?
Emily, butter would be the best substitute, or a vegan butter alternative would probably work too. If you try it, let us know how it turns out!
Are bittersweet chocolate chips the same as dark chocolate chips? I can’t wait to try these!
Jennifer, either will work in this recipe!
I absolutely love these! Could I add protein powder and/or like chia seeds and flax seeds too or would that mess up the batter?
Madison, I think you can play around with adding a tablespoon or so of each. Adding more than that will change the ratio too much. If you try and find a combo you like, let us know!
Hi! I’d love to make these!! I do not have any oats/flour but have almond and coconut flours. Are you able to guide me in best substitution? Thanks so much! I’m new to your blog and love your recipes!!-clayton
Clayton, I haven’t tested this one with other flours, but usually almond flour is a good substitute for oat flour. Don’t use coconut flour, it won’t work. If you try with almond flour let us know how it turns out! 🙂
These are delicious! We’ve already made them twice. Thank you for a great muffin recipe!
Wonderful, so glad you’re enjoying these Trisha! 🙂
I just found this recipe on Pinterest. It is a huge hit with my family! I will definitely be making these again. Thanks for the great recipe!
Fantastic, so glad you enjoyed Erika!
I make these weekly, I sub 1/4 cup of the oatmeal flour for 1/4 cup of hemp protein powder. The kids (13 and 14 year olds) love them,
So glad you and your crew are enjoying these. Love your adaptations!
