These brownies with banana and peanut butter have come in handy in multiple instances.
One of my biggest pet peeves is when I really want something (like dark chocolate brownies) but I lack some key ingredients, like eggs.
When this happens, I adapt and that’s how these peanut butter banana chocolate brownies came about. I didn’t intend to make these peanut butter brownies vegan, but back to the egg situation.
If we’re making peanut butter banana brownies (or anything with peanut butter for that matter), you can count my kids in.
Peanut butter is a staple food in our house.

So, these peanut butter chocolate banana brownies are a healthyish treat that came about out of luck, and now we rely on them for our weekly meal prep snacks.
Plus, you only need one bowl.
There’s nothing wrong with making regular brownies! But, when you’re making them each week, it is nice to have a lower-sugar option for toddlers and kids.
So, we rely on these peanut butter chocolate banana brownies and silken tofu brownies a lot!
Ingredients You Need
As you can guess, you need a few key ingredients, plus some others.
- flax eggs – I love this flax seed for making flax eggs. If not vegan, regular eggs will work great.
- medium-ripe bananas – These really make the brownies naturally sweet and the perfect texture. The riper your bananas, the more natural sweetness.
- coconut oil – If you’re not vegan, you can use butter in place of coconut oil
- applesauce – I used unsweetened since I added maple syrup as a sweetener. However, you could also opt for sweetened applesauce.
- maple syrup – optional
- vanilla extract
- whole wheat flour
- cocoa powder – I order this from Thrive Market
- baking powder
- salt – this sea salt on top is to die for
- creamy peanut butter – this is the best “creamy” peanut butter I’ve found. Almond butter, cashew butter or any nut butter replacement works too!

I’m sure that these healthy banana chocolate brownies will become your favorite way to use ripe bananas.
I know we all have them and then blank on how to use them. Well, ripe bananas are now prime real estate for banana chocolate peanut butter brownies.
How to Make Healthy Brownies with Banana and Peanut Butter
These peanut butter banana chocolate brownies come together very easily, which is a major win.
First, you have to make your flax egg, which is a vegan alternative to using real eggs.
Just mix 1 Tbsp of ground flax seed with 2.5 Tbsp of water, and let it gel. We’re using two flax eggs, so I doubled that recipe.

Next, mash your bananas in a large bowl with a fork. Using ripe bananas will make these easier to mash (and taste sweeter).
Then, add your coconut oil, applesauce, maple syrup, vanilla, flour, and baking powder to the bowl.
Finally, mix in your cocoa powder and flax eggs. You’re almost ready to pop these eggless peanut butter brownies in the oven!

Pour the batter into a 9×9 baking pan and swirl in the peanut butter with a knife (see tip below on the best way to swirl).
Then, bake for 27-32 minutes. Test with a fork or toothpick – when it comes out clean, they are done.

I know you’ll want to dive right in, but you want to make sure you let them cool completely before cutting.
I like to sprinkle some sea salt on top as they’re cooling to help bring out more flavor.
You really can’t go wrong with peanut butter, banana and chocolate.

I played around with a few versions and I’m thrilled with how gooey, soft, chocolatey, and peanut-buttery these peanut butter chocolate banana brownies came out.
How to Store Peanut Butter Banana Brownies
You have three choices for storing these healthy peanut butter banana chocolate brownies.
You can store them at room temperature in a tight container or bag, a stasher bag, or in the fridge, and they will last 5-7 days.
You can also freeze them for up to 3-4 months. Make sure to add them to your freezer prep before baby or even as freezeable snacks for toddlers, or snacks.

These tasty banana peanut butter brownies are in a world of their own.
They’re different from my vegan protein bars and pumpkin blondies because they don’t use beans, but all are delicious and healthy snack recipes.
Expert Tips
- When swirling the peanut butter, I like to make sure it mixes well into the bottom of the batter too, not just the top. This gives a fuller and deeper flavor to these easy banana brownies.
- Wait until the brownies cool before cutting them. This is the hard part but if you cut them when they’re too warm and soft, they will crumble easier!
- Sprinkling a quality sea salt on top will help bring out the flavor.

Support Bucket List TummyI printed this recipe and look forward to my blender results in the AM! 👍
I love making a batch of these when I have friends coming over – some of whom are vegan and others are not, but they all love them!
Can you use regular whole wheat flour instead of white whole wheat flour? That’s what I have at home. Can’t wait to try these!
Yes, whole wheat flour will work just fine, just may be a little heartier 🙂 Hope you like them!
Very easy to make and taste good
Thanks Sarah. Might try it tomorrow. Will let you know
Can you use applesauce instead of the bananas? If so, how much? Thanks!
Hi Tami! I did not test this, but it looks like you can substitute 1/2 cup of applesauce for each banana (so about 1 cup of applesauce for the 2 bananas): https://www.thespruceeats.com/banana-equivalents-1807459
Let us know how it comes out!
If using real eggs ????, how many would use ?
It’s a 1:1 substitution with flax eggs, so two whole eggs!
I’ve printed this recipe out and I can’t wait to try them. They look so gooey and delicious – thank you for sharing the recipe for us xo
Hope you enjoy them, Gemma!
Absolutely cannot wait to try these!

I was going to make your pumpkin chocolate chip chickpea bars this weekend but then Alex’s parents got him a Valentine’s Day chocolate box which means I’m eating those instead haha.
