An Easy, MOIST Banana Cake Recipe
This banana cake recipe is a result of many, many emails and comments from so many of you writing to tell me how much you enjoyed my banana muffinsย (see, I didn’t call them the “best” for nothing).ย
A few of you wrote to ask me if it would be possible to bake the muffin recipe into a banana cake, but I had a few reservations. I was worried that the original recipe wouldn’t make the best banana cake, and so I started recipe testing to develop the perfect moist cake.
I went through a lot of overripe bananas (and some not-so-ripe ones, in moments of desperation), and finally ended up modifying my pumpkin cake (of all things) to land on this winning banana cake recipe. It’s incredibly soft, fluffy yet moist, and topped with a smooth and creamy version of my popular cream cheese frosting (though to make things extra decadent try it with my brown butter frosting!).
Let’s get started:
๐ง Ingredient Overview
My banana cake recipe was carefully and intentionally designed to be sweet, simple, super flavorful, and moist. There are a few key players that help make this happen. For those of you interested in the thought behind the ingredients, let’s discuss:
- Bananas. For the best flavor & moistest cake, you should use ripe, spotty, brown bananas. Have some that are looking a little overripe on your counter and starting to attract fruit flies? Grab those. Ideally I prefer mine to be browner than the too-yellow ones shown in the photo above (but my recipe is versatile, so use what you have on hand!). King Arthur has a great guide on choosing the best bananas to use.
- Butter AND oil. Those of you who have made my vanilla cake or marble cake recipe know that a blend of the two yields a better cake than simply using all butter or all oil. All-butter cakes are more dense and dry than all-oil ones, but using all oil mean you lose that precious buttery flavor. For my banana cake recipe I sought balance, and a blend of the two yielded a perfect moist cake. For the oil, any neutral cooking oil (canola or vegetable are most common) will work.
- Sugar. Another best-of-both-worlds scenario. Granulated sugar adds sweetness without weighing the cake down too much, while brown sugar adds depth of flavor. Light or dark brown sugar will work, but dark brown sugar makes the cake a bit richer and sweeter.
- Leavening Agents. Baking powder and baking soda are welcome additions here, they add a bit of lift to the cake to make it perfectly fluffy. Without the two of them we’d have a dense, gummy cake. .
- Buttermilk. While this plays a role in helping the banana cake to rise a bit when combined with the baking soda, more importantly it adds moisture and a very subtle tangy flavor. You may use my buttermilk substitute if you can’t find buttermilk in stores (or just don’t have any), but the “real” stuff is best here.
This is just an overview of a few of the main ingredients I used and why. For the full recipe please scroll down to the bottom of the post!
How to Make the Cake Layer
- Use a potato masher or fork (or even a mixer) to mash the bananas, eliminating as many lumps as you can (you won’t get all of them, that’s OK!).
- Beat together the sugars and butter until light, creamy and well-combined. Then, stir in your oil until it’s incorporated.
- Add the bananas to the butter/sugar mixture and stir well to combine.
- Add the eggs, buttermilk, and vanilla extract and stir well. The batter most likely won’t be smooth since your mashed bananas are bound to be a bit lumpy, but everything should be thoroughly mixed.
- In a separate bowl whisk together the dry ingredients.
- Add the flour mixture to the wet mixture gradually. You want the ingredients to be thoroughly combined, but as with my banana bread, over-mixing can result in dense, dry results. One of the things that helps keep this banana cake recipe so moist and perfectly textured is being sure to not overdo it when combining the wet and dry ingredients. Either fold them together by hand using a spatula, or use an electric mixer on low-speed and stir until just-combined.
- Spread the batter evenly into a greased 9×13″ baking pan. I use a metal pan, if you use a glass one note that your cake will take longer to bake than indicated.
- Check the doneness of the cake by inserting a toothpick into the center. The toothpick should come out mostly clean, or, preferably, with some moist crumbs (but no raw batter!).
How to Make Banana Cake Frosting
The other day someone commented to me that they’d eat shoe leather if it had cream cheese frosting on it. That resonated with me ๐. Cream cheese frosting complements everything, and it was a no-brainer that this was the perfect choice for when developing the BEST banana cake recipe. Fortunately, it’s also very easy to make:
- Combine (softened, full-fat) cream cheese, butter, vanilla extract, and salt and beat until smooth and creamy. There should be no lumps remaining (if it’s lumpy, your cream cheese may have been too cold).
- With mixer on low speed, add the powdered sugar in small increments until it is all mixed in.
- Add the cream gradually while increasing the speed of your mixer from low to high. Beat on high-speed for 30 seconds (this helps whip some air into the frosting, making it smooth but also stable) and you’re finished!
- Spread the frosting over the (cooled) cake. Top with regular or toasted pecans or walnuts (or a drizzle of caramel sauce or dulce de leche ๐คค) for a finishing touch!
Frequently Asked Questions
This banana cake recipe should yield results that are perfectly moist, but certainly not oily. If yours seems more of the latter than the former, consider these possible issues.
1) Using too much banana can make the cake too wet and make it seem oily. While just grabbing 4 ripe bananas might work out just fine for you, if they’re larger than you realize it could cause a wet cake, and for this reason I recommend you mash and then measure your bananas.
2) Not thoroughly combining the wet ingredients, or not thoroughly combining the wet and dry ingredients together. Make sure you stir very well when mixing the butter/bananas etc., then when you combine the wet and dry ingredients do so carefully but thoroughly (remember that over-mixing at this step can yield dense, dry results).
3) Under-baking. Examine your toothpick carefully when testing. With such a moist cake, sometimes the toothpick may appear clean when there’s actually a thin, nearly translucent layer of banana cake batter on it. The toothpick should be dry or (preferably) have moist, discernible crumbs.
Either over or under-mixing can result in a cake that sinks as it cools. If the banana cake is not baked thoroughly, this can also cause it to sink after baking. Finally, if your baking powder or baking soda are expired and/or not properly stored, this may cause the cake to not rise properly. Store these in a cool dry place and make sure they are not expired before you use them.
This cake is very carefully and specifically designed to be moist, so it’s unlikely you’ll run into this issue (I’m not sure anyone has so far!) BUT, if you do it’s likely because:
1) The flour was accidentally over-measured. I recommend that you use a kitchen scale or stir your flour, spoon it into a measuring cup, and then level it off (see my post on how to measure flour).
2) It was baked too long or your oven is running too hot. Unfortunately many ovens do not run true to temperature, and for this reason I recommend keeping an oven thermometer in yours.
It took quite a bit of tweaking and testing but I’m very proud to finally be sharing my favorite banana cake recipe with you. If you try it, please leave me a comment letting me know how you liked it!
Enjoy!

Notes
ยนBaking note:
Keep an eye on your banana cake as it bakes. 30 minutes in, check your cake to see if it’s becoming too brown on top (pay attention to the edges, if they’re getting darker in color and pulling away from the edges), if so you may lightly tent with foil before baking the remaining 15 minutes. I had this issue when baking in a glass dish but not in a metal one (which was the opposite of what I expected).ย ยStoring
I store my cake in the pan that I baked it in, covered. It will keep at room temperature for up to 3 days or in an airtight container in the refrigerator for up to a week.ยNutrition

antika
hey! can I make this in two 8inch pans? i want to make layer cake. thankyou!
Sam
Hi Antika! I haven’t tried baking it in 2 8 inch pans. You will have enough batter so I don’t see any reason it couldn’t work. ๐
Shelley Johnn
Hi Sam. My first time baking one of your recipes and WOW what a success! My 96 year old mother wanted me to use up some of the oatmeal as I overbought on a BYOB. I found your best chewy oatmeal cookie recipe and made them the day my daughter Sam came over with my 15 and 16 year old grandsons to go swimming. The cookies were almost gone before they went home and I just finished baking a second batch for my mother. Thank you for being such a perfectionist. I am trying the banana cake recipe next.

Amelia
Can I make this into cupcakes? What would you suggest as the bake time then?
Sam
Hi Amelia! I would recommend my banana cupcake recipe instead, which has been particularly designed to work best as cupcakes (it is closely based off of this recipe).
Magee
Can I put chocolate chips? Please let me know
Sam
Hi Magee! That will work just fine. I would just stir them in briefly at the end. ๐
Evelyn
Hi, can I use cake flour instead of regular flour for this cake recipe?
Sam
Hi Evelyn! I haven’t tried it but I think it could work if substituted properly. ๐
Jennifer
Hi Sam! I really want to make this but I donโt like walnuts. Do you think pecans would be ok? Or would I be better off just leaving the nuts out? Thank you!
Sam
Hi Jennifer! You could use pecans if you’d like or you can just leave them off. ๐
Larry
Made this tonight. I added raisins. We can’t have nuts so I added red sprinkles to the top. Very tasty. thanks for the recipe.
Sam
I’m so glad everyone enjoyed it, Larry! ๐
Hamida Musa
Pls how much white sugar can you add if you can’t get brown sugar??
Sam
Hi Hamida! You can use the same amount of granulated sugar. The cake won’t be quite as moist and flavorful. I do have an article on how to make brown sugar you could check out. ๐
Jess
I love this cake recipe so much! I have made it twice and I make it into a cute little layered cake with the naked frosting look and it turns out so so cute and delicious!
Sam
I am so glad you enjoyed it so much, Jess! ๐
Samantha
Hi Sam, your blog is definitely one of the best baking blogs out there and I am honestly so grateful to have stumbled upon it! I am planning to bake this banana cake as a layer cake and fill it with pastry cream for my mom’s birthday. Which frosting do you think will go well with that combination? Thank you so much!
Sugar Spun Run
Happy (early) Birthday to your mom, Samantha! If you are planning to create a banana cake, with a pastry cream center, I would reccomend either the cream cheese frosting, vanilla buttercream, or chocolate cream cheese frosting. One of those options would work nicely. I hope that your mother enjoys her cake. Keep me posted on how it turns out! ๐
Samantha
Tasted soo delicious! My mom ate half of the cake in one day, its now her favorite๐!
The chocolate cream cheese frosting, pastry cream, and this amazing banana cake went together so well! Thanks for all of the awesome recipes, Sam!
Sam
That is so awesome! I’m so glad everyone enjoyed it so much. Sounds like mom will be asking for another one soon. ๐ ๐
Janet Pohl
The best banana cake I ever ate! The frosting is very special, too, and suits the cake perfectly. I made this for a birthday cake and we all loved it. Thank you so much for this recipe.
Sugar Spun Run
I am so glad that everyone enjoyed it, Janet! Thanks for using my recipe for such a special occasion. ๐
Jane
Is there any other type of glaze or frosting that you would recomend with this cake? I want to make this for my mom but she’s not a big fan of sugar so if there was anything that isn’t as sweet but taste good with this cake I would love to try it out. Thanks!
Sam
Hi Jane! You could use the glaze that I use in my bundt cake but I honestly like the cream cheese frosting here because I don’t think it’s overly sweet.
Sash
Can I make cupcakes with this recipe ?
Sam
That should work here. The cupcakes may not bake up very tall but they should definitely still turn out. ๐
Jonie
I really love this recipe. Is it sturdy enough to make it as a layer cake?
Sam
Hi Jonie! It should hold up pretty well for you. ๐
SandyH
Is there no brown sugar in the frosting?
Sam
You may be remembering my brown sugar frosted banana cake, but I have since removed that recipe as this one is much much better. If you want a brown sugar frosting you can use the frosting from my pumpkin cupcakes. ๐
