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

Shakila
Hello Sam! Greetings from Singapore! Ever since I tried your best cheesecake recipe, I’ve honestly trusted you hehe. I tried making banana cake yesterday with milk (without the lemon) and to my surprise, it still tasted good. I honestly love the moist and texture. My friends love it too! Thanks so much!
Sam
I am so glad you enjoyed it so much, Shakila! ๐
Hansa
Hey I made this cake in the evening, I skipped the frosting and the walnuts cause I didn’t have cream cheese or walnuts and even without a frosting the cake turned out to be a hit among the family. My parents who usually dont consume sweets much loved it and asked for a second piece. Thank you for the recipe. I made this in a glass dish and had to cook for 55 mins(just like you’ve said).. I put some cashews on top of the cake 20mins before taking it out. Amazing ๐ oh btw this was my first time eating a banana cake so I was a bit concerned making this cause I wasn’t sure what it should taste like or anything ๐ turns out I like banana cake
Sam
I am so glad you enjoyed it so much, Hansa! ๐
Rookie Baker
This is the second recipe from you after the chocolate cupcakes and this banana cake did not disappoint, itโs indeed the best! Again a big hit in our family. Thank you.
Instead of using cake pans, does it make any difference if I use cupcake pans? Thinking about portioning…
Sugar Spun Run
Thank you for visiting my site again to try another recipe, Wendy! I am so glad that you enjoyed the cake. I have not personally tried baking this recipe into cupcakes, however, it should work fine. You will want to keep on eye on it while it bakes as the bake time will be different. If you try it, I’d love to know how they turn out and how long it took for them to bake. Thanks for commenting. ๐
Melissa
I reduced the total sugar amount to 1 cup (granulated sugar) & added a handful of chocolate chips and it was still amazing!!!! IMO, could have gone down even more to 3/4 cups of sugar to make it โhealthierโ
I reduced 1 tablespoon of butter as well & it was ok too!
Sugar Spun Run
I am so glad that you enjoyed it and it turned out well even with some adjustments, Melissa! Thanks for commenting. ๐
Ana Beatriz Fernรกndez
Loved this banana cake! It was so moist and flavorful. This has now joined my all time favorites next to your delicious carrot cake! I would also love to see some microwaveable mug versions of your delicious desserts, since your page is now my go to for all things sweet except when I have a sweet tooth attack and I need to make something quick like that. Thank you so much for your great work!!!
Sugar Spun Run
Thank you so much for your sweet comment, Ana! I am so glad that you have enjoyed my blog and my recipes! I love that I have become a go-to site for all things sweet! I appreciate your feedback. I will add mug cakes to my list! ๐
Cindy
Hi Sam,
I was wondering if I could put a crumb topping on top of this cake. I am trying to re-create a banana crunch cake from Entenmannโs that was discontinued. I made one a week ago in a dark metal pan, and it was overcooked even though I removed at 10 minutes earlier than stated. So, do you think a crumb topping would work on this recipe, and should I def use a glass pan because it sounds absolutely amazing!!
Sugar Spun Run
Hi, Cindy! A crumb topping would work well on this. I have a banana muffin recipe that uses a streusel topping that you can check out as well. Glass or metal pan will work for this recipe. You will keep an eye on it while it bakes as timing may be slightly different. I hope that you enjoy the cake. Keep me posted on how it turns out. ๐
Nadia
Wow Iโve tried my fair share of banana cake recipes and this one takes the cake! Itโs super moist and the flavour is all banana…yum!
I did misread the instructions about putting it in a pan and instead used a springform round pan & the middle was slightly undercooked after the 45mins. Next time Iโll use the pan. Thanks so much for sharing your recipes, delicious (from Australia)
Sugar Spun Run
Thank you so much for trying my recipe, Nadia! I am so glad that you enjoyed it! Thanks for commenting. ๐
Cate
I have tried banana bread recipe and came out awesome. Checked banana cake and recipe seems the same. What is the major difference between the 2.
I also enjoyed the lemon blueberry and is my best recipe!
Thanks for your great work. You truly inspire me
Sugar Spun Run
Hi, Cate! Thanks for trying my recipes, I am glad that you have enjoyed them. The ingredients between the banana cake and banana bread are similar, however, the banana cake is much more moist and is paired with a cream cheese frosting. If I had to pick one, the cake would be my favorite out of the two. ๐
Cate
Thank you sam. Now I know. Determined to try all your recipes coz they are simple and amazing
Sugar Spun Run
Thank you so much for your support, Cate! I greatly appreciate. Excited to see which are your favorites. ๐

Alright, this is now the second recipe of yours that I have tried and I love it just as much!! The whole family does. Swapped out buttermilk for full fat as I didnโt have any, still tasted incredible!! So impressed with your recipes!
Thank you for turning this non baker into a baker!
Sugar Spun Run
I am so happy that you have enjoyed another one of my recipes, Andrea! Thank you so much for trying it. Enjoy! ๐
Joanne
Hey Sam!
I’d like to try this recipe. Would frozen bananas work?
Sugar Spun Run
Hi, Joanne! Yes, frozen banans will work, but will need to the thawed before making this recipe. I hope that you enjoy the cake. ๐
Leah
Hello Sam, I did it! I baked this recipe in two 8″ rounds. I have a family member who has an aversion to cream cheese icing, so I made peanut butter icing instead because, hello…peanut butter and banana!! It was a hit and my family loved it. I wish I could post a photo! Thank you for the inspiration!
Sugar Spun Run
Hooray! I am so glad that you were able to accommodate all taste buds and the cakes turned out perfectly, Leah! Peanut butter frosting was an awesome choice. Yum! Thanks for commenting. ๐
Donna Marie Rogers
Hi Sam…Love your site! I’ve been cooking a lot more than usual these last few weeks, and we always have overripe bananas, so I was excited to find this recipe (your cream cheese frosting is the first recipe of yours I made, and my daughter deemed it the very best!). For the Silky Cream Cheese Frosting, could I sub Half & Half for the heavy cream? Thanks!
Sugar Spun Run
Thank you so much, Donna! I am so glad that you have enjoyed my site along with my recipes. I hope that you love this cake. As for the frosting, half and half will work fine. Let me know how it turns out for you!
Donna Marie Rogers
This cake was moist and delicious, and the silky cream cheese frosting was amazing!! My daughter and I fought over the last piece…LOL Thanks so much, Sam, going to try another recipe this weekend…just have to figure out which one…so many choices!
Sugar Spun Run
I am so glad that you enjoyed the recipe, Donna! Thanks for commenting. Since you both fought over the last slice, I guess you will need to bake another. lol ๐
