Makes 12 slices

Here we’ve got something that reminds me of pressing my face against the glass dessert case at my neighborhood Jewish bakery. Marbled treats were a childhood fascination and they still hold some of that “how did you do that?” wonder. Swirls of cocoa through banana bread. It’s a simple trick but it never gets old.
This vegan marble banana bread is perfectly banana-y, not too sweet, and surprisingly low fat — only 2 tablespoons of oil in the whole loaf. The banana does most of the moisture work, which means the crumb stays tender and almost fudgy without needing a lot of fat to get there. The outside gets a little crunchy from baking, but leave it in Tupperware or wrapped at room temperature overnight and it gets even more moist. It tastes great both ways but the next day version is genuinely special.
The marbling takes a little extra work and a couple of extra bowls — but isn’t it worth it to awaken that childhood intrigue? You scoop out a cup of plain batter, mix it with bloomed cocoa, then alternate spoonfuls of each in the pan and drag a butter knife through in lazy circles for about ten seconds. That’s it. Then the baking process takes care of the aesthetic. Glossy, swirly and completely wonderful.
One reader said they make two loaves a week. Another said it makes the best French toast they’ve ever had. Both of these people are onto something.
VEGAN MARBLED BANANA BREAD FAQ
How ripe do the bananas need to be for vegan banana bread? Very ripe, the more black spots the better. The riper the banana the sweeter and more flavorful the bread. Frozen bananas work great too, just thaw them first. They mash up perfectly and some people swear frozen bananas make even better banana bread.
Why is my vegan banana bread flat? Most likely culprit is old baking soda. It loses its power over time and won’t give you the lift you need. Make sure yours is fresh. Also make sure you’re using an 8×4 loaf pan — a larger pan will spread the batter too thin.
Why does vegan banana bread get rubbery? Banana bread can get rubbery if you work the batter too hard once the flour goes in. Mix just until the flour disappears and stop. A few streaks are fine. Gentle is the move.
Can I make vegan banana bread muffins with this recipe? Yup. Fill liners about 2/3 full and bake for about 18 minutes. Makes 12 muffins. Reader approved.
Can I add walnuts to vegan marble banana bread? Yes yes a thousand times yes. Fold a cup of chopped walnuts into the batter. Toasted walnuts are especially good here.
Can I add chocolate chips to vegan marble banana bread? My word, you have good taste. Add 1/2 a cup.
Is this really THE BEST vegan marble banana bread recipe? I promise. And look at the comments.
What do I do with leftover vegan banana bread? Make French toast. Seriously. Thick slices of this bread in a pan with a little oil or vegan butter — it is one of the best French toasts you will ever eat. You’re welcome.
How did I end up here? Searching “vegan marble banana bread” maybe? Or “vegan banana bread,” “chocolate banana bread,” “easy vegan quick bread.” Could have been “what do I do with these ripe bananas” at 10pm. All roads lead here.

Marbled Banana Bread
Ingredients
- 1 cup mashed very ripe banana
- 3/4 cup sugar
- 1 teaspoon pure vanilla extract
- 2 tablespoons canola oil
- 1/3 cup almond milk (or your preferred non-dairy milk)
- 1 1/2 cup all purpose flour
- 3/4 teaspoon baking soda
- 3/4 teaspoon salt
- 3 tablespoons unsweetened cocoa powder
- 6 tablespoons boiling water divided
Instructions
- Prepare boiling water, no need to measure yet. Also, preheat oven to 350 F.
- Mash the banana in a large mixing bowl until relatively smooth. It should take 3 average sized ones, but spoon the mashed ‘nanas into a measuring cup to make sure, then return to the mixing bowl. Beat in the sugar, canola oil, milk and vanilla.
- Now add the flour, baking soda and salt and gently mix just to incorporate. It’s okay if there is some flour still visible, just be careful not to overmix at this point.
- Scoop one cup of the batter up and transfer it to a separate mixing bowl. Now, in a small tea cup mix the cocoa powder with 3 tablespoons boiling water and stir vigorously with a fork until the chocolate is dissolved. Add this chocolate mixture to the one cup of banana and mix until the chocolate is thoroughly smooth and incorporated.
- Now back to the original plain banana batter; add 3 tablespoons of boiling water and mix the batter just until relatively smooth.
- Here comes the fun part, it’s time to marble! Lightly grease an 8×4 loaf pan. Scoop alternate 1/2 cupfuls of chocolate/banana batter into the loaf pan. Nothing has to be precise here, in fact, the more random, the better. Once all of the batter is in, take a butter knife and swirl it through the batter in circular directions for about 10 seconds.
- Bake for 55 minutes. Use a butter knife to test for doneness. Let cool and enjoy!

Hi, just bought your beautiful cookbook, working through it and loving it. Re this marble bread, does it freeze well? I have a bunch of rip bananas but need to store this bread for a future party…
It does! I’ve made and froze it whole and it cuts like fresh. Just let it cool completely on the counter, then wrap tightly, cool in the fridge for a bit, and and then stick in the freezer.

It’s for the marbling effect.

This is now my go-to banana bread recipe! I love how your recipes are perfect the way they are while also being so tolerant of tampering. If you’re just looking for bread, rather than a sweet treat, I’ve gotten the sugar down to 1/4 cup. (Especially if you’re just going to put jam on it anyway…) I’ve also successfully used whole wheat pastry flour – perfect – and regular whole wheat flour. The regular whole wheat sucks up a lot of moisture, so it’s hard to avoid over mixing, but it comes out just fine.
(swapping whole wheat flour and cutting sugar to 1/4 cup brings the calories from 220 to 141 for an eighth of a loaf)
@ Elissa – the purpose of separating out the batter is that only some of the batter gets the cocoa so that you can marble the cocoa colored banana bread batter with the regular banana bread batter
oops – I meant 170 calories for 1/4 c. sugar, whole wheat flour. (Too much banana bread; my fingers are getting chubby 😉 )
Love, love, love! Best banana bread I’ve ever had! My whole family agrees.

this is my favourite Isa recipe of ALL TIME.
With the big muffin tin, took 25 minutes.
Thank you so much for this. Just made muffins and the timing was perfect.
I have made this recipe (out of Isa Does It) several times and it is a major winner. We have successfully substituted 4 tb. melted chocolate for the water/cocoa mixture in a pinch.
Do you think
This could work with avocado ??

Just put this in the oven….hoping for a delicious treat! ❣
This was soooooo delicious & fun to make 🙂
Thank you Isa 🙂
It’s going straight on my FB, Instagram & groups letting everyone know to try it with your link attached 🙂
So good & happy 🙂
This recipe is incredible. I’ve made it 15 times and it always turns out beautifully. It’s the first banana bread recipe that I’ve tried and not been disappointed with.
I love this recipe, but I substitue 6 squares of Baker’s unsweetened chocolate for the cacao powder/water (if you like it less chocolatey, use 4 squares) … it’s THE BEST banana bread recipe ever, and so easy!
This recipe is still going strong, it is tried and true! Makes great mini loaves for bake sales or random gifts.
Great recipe! One of the first vegan banana bread recipes I made years ago!

This was incredible and EASY. The small amount of oil really helps with the texture and moistness. I used about 1/8 cup less sugar bc I was using regular almond milk rather than unsweetened and it’s perfectly sweet.
this sounds great.. but not a big fan of bananas.. i know thats the point.. but looking for a marble loaf.. like i used to getin brooklyn ( leons!)
can u possibly recommend a sub.. would applesauce work. im thinking pumpkin would, but that would change flavor and color…
cant seem to find a good marrble loaf recipe.. even Fran doesnt have one..
Can I ask the size of your loaf pan?
Thank you ☺️
I’ve been making this banana bread for years. It’s the best!
This recipe’s such a winner, please never take it down! So easy and so good. I don’t visit this site as often because I don’t do cane sugar anymore, but I used 1/2 c coconut sugar in this recipe since I remembered liking it (though I’m not a big fan of banana bread in general), and it still turned out great. It also rose impressively with no adaptation: perfect texture! Thank you, Isa Chandra!
I’ve made this recipe doezens of times over the years and it always hits the spot! Easy and comforting ❤️
My go-to banana bread recipe, it’s so good and the marbling gives it a little something extra! I’ve added chocolate chips, nuts, and made it as muffins. Sometimes I don’t do the marbling part but the base recipe is still perfect. Highly recommended!
This looks great when you slice it open! It’s one to impress your friends with. The extra dishes may seem like a bit of a faff, but it’s worth it for how pretty it looks. It tastes amazing too.
This is probably my most-made recipe from Isa Does It (or maybe the chocolate cake, which is the foundation of every bday cake I have made my kids for ages). Everyone loves it and asks for the recipe, and the marbling makes it look like you are a pro baker that actually knows what you are doing even if all you can handle is following a recipe. It’s just fantastic!
