Here are the ingredients you’ll need for this recipe, including substitution ideas:
- Vegan Butter — Use vegan butter or substitute melted coconut oil.
- Flax egg — You can use a Flax Egg or substitute a Chia Seed Egg.
- Brown sugar — Use light, dark, or homemade brown sugar.
- Flour — I used all-purpose flour, but you can substitute Whole Wheat Pastry Flour or even gluten-free baking flour.

What Bananas are Best?
Look for bananas with a few or even a lot of brown spots. If the banana is too ripe (verging on dark brown or even black), the flavor may be too overpowering and the consistency too soft.

- Stir together the flour and salt.
- Make the batter by stirring together the wet and dry mixtures.

Marly’s Tips
- You can add up to a teaspoon of cinnamon to the blondie batter
- For a festive event, add some colorful sprinkles on top
- Make banana chocolate chip blondies by adding a cup of dairy-free chocolate chips to the batter.
- Make it a bit lighter by halving the peanut butter frosting on top.

Frequently-Asked Questions
Can you freeze banana blondies?
You can freeze blondies by wrapping them tightly in plastic wrap or transferring slices to a freezer bag. They can be frozen for up to 2 months when stored properly.
How are blondies different than brownies?
Whereas brownies are infused with chocolate flavor, blondies have notes of caramel thanks to the use of brown sugar in the batter. You can add different flavorings, such as bananas, to accommodate different tastes.
What is the texture of a blondie?
A blondie texture is very similar to a brownie, in that it is dense and gooey. The trick to achieving gooey blondies is to not use a leavener (such as baking soda or baking powder) and to not overbake them.

I honestly don’t even like bananas, but like, these sound really good!
I have these in the oven now while my wife is sleeping. I wanted to surprise her tomorrow! The batter was amazing! Can’t wait to give them a try. I’m using my grandmothers old fashioned cooked peanut butter icing which I veganized. So delicious pours right over the top and firms up into a soft peanutbutter fudge.
Toni! Your description sounds heavenly. Your grandmother’s recipe sounds perfect! ❤️
Love these! I have really been into baking with bananas lately. Maybe it’s the weather, but banana treats just feel so cozy. Can’t wait to give these a try. That peanut butter frosting is sending me over the edge!
I made these last night and they were so good! Excellent recipe 🙂
I’m SO glad, Jessica! Thanks so much for coming back to tell me this. I loved this recipe too – so simple and yet so flavorful. XOXO, Marly
Omg Marly, your recipes look fantastic! I can’t wait to try these banana blondies–as well as many other amazing recipes on your website! I’ll let you know how it goes 🙂

Thanks SO much Roula-Maria! By the way, great name! You’re the best!

What incredibly and sweetly delicious blondies. I just love the look of them – and all that oozy peanut butter frosting!
OMG, Thalia, that oozy peanut butter frosting is the BEST! I could have eaten that with a spoon. Oh wait. I think I did! Oh well, less frosting for the blondies is ok. Right?
These looks scrumptious! Do you think I could substitute almond or coconut flour for the flour, and use xylitol or stevia for the brown sugar? I’m adrenally challenged and the sugar and carbs tempt me so.. but just aren’t good for me. lol
These blondies are so moist that I bet you could get by with using either almond or coconut flour. Regarding the sweetener, I could see trying the stevia. But I’ve been into date sugar lately. Have you tried that? Or even coconut sugar. I’m not sure how these impact your condition, so you will have to make that call in the end. Let me know how it goes!
These blondies look heavenly! Can’t wait to try this amazing recipe!
Thanks so much Sommer! You made my day! 🙂
Anything with peanut butter seems to win my family over, yum! Especially Peanut Pan Peanut butter (i know, not the best for you, will try the organic kind instead =)
I think your family and my family has a lot in common Laura! Honestly, I use the organic peanut butter, but I also buy brands like Jiff and Peter Pan, especially their natural varieties. I find they work really well in recipes like this one. I hope you love these Banana Blondies as much as we do!
Good gracious these look good!!! Definitely putting them on my To Make list!
Thanks Jenn! I hope they tickle your fancy! 🙂
