This is the best banana cake recipe, and it’s made completely from scratch! My recipe is perfectly balanced with extra bananas and complementary spices and is crowned with a silky smooth cream cheese frosting. Includes a how-to video!
The Actual Best Banana Cake Recipe (Moist, Easy, & Frosted!)
If you have some overripe bananas hanging out on your counter, I’ve got you covered: this banana cake recipe is exactly what they’ve been waiting for. Soft, plush, rich with banana flavor and smothered in a silky smooth, perfectly tangy cream cheese frosting, this recipe is made completely from scratch. It’s easy with basic ingredients and the prep takes less than half an hour, so what are you waiting for!?
Why This Banana Cake Really Works:
- Bananas are for more than just flavor. Overripe bananas aren’t just essential for locking in classic banana flavor. They’re also full of natural sugars and pectin, which help lock in moisture and create a plush, super moist crumb that stays soft for days.
- Butter for flavor, oil for texture. This is a combo that I use in many of my cakes (both my vanilla cake and chocolate cake recipe feature a blend of the two). While butter adds incredible flavor, butter alone can dry out a cake crumb a bit, especially one that needs to be refrigerated (since butter solidifies in the fridge it can make cakes seem dense and dry). Cooking oil is great for adding moisture, but doesn’t lend the same rich, buttery flavor. By using a blend of both, we get incredible flavor and texture.
- Cream cheese frosting, balanced just right. The tangy element of it works especially well here to counter the sweet, banana-rich base. A little acidity balances the whole bite, so it doesn’t feel too heavy! Psst: If you want to make this cake over-the-top luxurious, try it with my cream cheese-based brown butter frosting!)
Ingredients:
My banana cake recipe was carefully and intentionally designed to be sweet, simple, super flavorful, and moist. When developing it, I largely drew from my pumpkin cake (of all things). Let’s talk about a few of the key players:
- Bananas. For the best flavor & moistest cake, you should use overripe, spotty or mostly brown bananas. Have some that are looking a little sad on your counter and starting to attract fruit flies? Grab those. King Arthur has a great guide on choosing the best bananas to use for baking. A banana cake made with underripe or even regularly ripe bananas could be a bit less sweet, more dry, and underwhelming in flavor.
- Butter AND oil. Those of you who have made my Funfetti cake or marble cake recipe know that a blend of the two yields a better cake than simply using all butter or all oil. 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 a depth of flavor that pairs nicely with the bananas (thanks to the molasses in brown sugar!).
- Leavening Agents. Baking powder and baking soda create a perfect rise. The baking soda reacts with the banana and buttermilk (and helps create that beautiful golden surface), while the baking powder ensures a reliably even lift across the cake. 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, perhaps more importantly it adds moisture and a wonderful depth of flavor.
As always, 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 Banana Cake
Make the cake batter & bake
Start by mashing your bananas really well (a fork or potato masher works great). Set these aside and cream together your butter and sugars and gradually incorporate the rest of your wet ingredients.
The dry ingredients should be whisked together in a separate bowl, then gently stirred into the wet ingredients. Do not use your electric mixer for this step. Instead use a spatula to gently fold things together until the batter is completely combined. Overdoing it can cause the cake crumb to be dense and dry (don’t under-do it either, though, or the cake could sink or not bake properly).
ake the cake until it’s golden brown and a toothpick inserted in the center comes out clean or with a few moist crumbs. If you notice your cake is darkening more than you’d like in the oven, you can tent it with foil to prevent this.
SAM’S TIP: Measure your bananas! The recipe lists the amount of mashed bananas that you need for a reason, simply stating “3 bananas” or “4 bananas” is too ambiguous and could lead to a cake that’s too dry and bland (if under-measured) OR too moist and sinks in on itself (if over-measured). It’s best to mash and measure (or go by weight!).
Make the Cream Cheese Frosting
SAM’S TIP: The pan you bake your cake in matters. The banana cake will take longer to bake in a glass pan than a metal one.
The frosting is quick and easy to prepare. Beat softened cream cheese and butter, vanilla, and salt until smooth and creamy (make sure there are no lumps!), then gradually stir in the powdered sugar. Stirring in a bit of cream gives you a silky smooth frosting that spreads easily (similar to the one I use on my zucchini cake).
Top with regular or toasted pecans or walnuts (my preference), or make things extra decadent with a drizzle of caramel sauce or dulce de leche 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: Too much banana. Extra banana (especially if yours were particularly large!) can make the cake batter too wet. For best results, mash and measure your bananas rather than try to guess a number of bananas.
2: Stir well (but don’t overdo it). The batter needs to be uniformly combined so that all of the ingredients can properly interact with each other. If you don’t mix in the proper order or well enough, you could have spots within the cake where the oil didn’t have the chance to properly absorb into the batter.
3: It’s under-baked. This cake is very moist, so check your toothpick closely. It should come out with moist crumbs but definitely not a thin coating of wet batter. The toothpick should be dry or (preferably) have moist, discernible crumbs.
I have not one, but 3 secrets to share with you, but know it’s all about a smart selection of ingredients and a little baking science.
First: very ripe bananas are key to a good banana cake recipe! As bananas ripen, their starches turn to sugar and the moisture content increases, keeping the cake moist and flavorful.
Second: a blend of oil and butter adds both moisture and flavor.
Finally: just the right amount of brown sugar. Brown sugar doesn’t just add flavor, it also helps the cake stay soft and tender even after a night in the fridge, thanks to the fact it’s hygroscopic (this just means it loves moisture!).
Banana bread is baked in a bread pan, is more dense and hearty and a bit less sweet. It’s not uncommon to find it on a breakfast menu. Banana cake, on the other hand, would be hard to pass off as breakfast food. It’s baked in a cake pan, fluffier and even more moist, and dressed up with a heavy-handed swirl of frosting.
Both over and 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.

AWESOME!! I made this for fellow nurses and we ALL love it !!!!!
Todd
. Recipe is easy to follow, all directions are perfect, if this didn’t turn out don’t blame the writer. You need to look at what you did wrong. My only comment is it is a bit sweet,FOR ME, yes we all have different tastes and you should adjust to what you like, but never change the recipe the first time then complain about something not being right. When I make this again I may try to cut some sugar, but I know my sweet toothed family will think it is perfect.
Lisa
Made this banana cake recipe over the weekend ! Obsessed it was so good everyone loved it and it was to overwhelming with banana flavor , it was perfect . Thanks Samantha 😊
Erika Flynn
I do not bake. I made this recipe. AMAZINGLY delicious and yes moist. 😋

A couple of years ago I was looking for a banana cake recipe that used a significant quantity of bananas. I found it. This was my introduction to your website and I have never looked back. This cake is beyond delicious, and the frosting perfectly compliments the cake. It is hard to eat only one piece. I actually have an unfrosted one in my freezer (can’t waste those overripe bananas). I love Sugar Spun Run!!!
Sam
I’m so glad you have enjoyed it so much, Gale! 🙂
Claire
Delish cake, thanks for putting the effort into creating a recipe so we can all enjoy it! I made x1.5 recipe in x3 8inch pans and baked for approx 50mins, no fan. They’re about 1.75inchs high each.
Paola
Fake reviews. Upon putting 2 stars on this recipe and leaving my review then submitting – I got this message “Duplicate comment detected; it looks as though you’ve already said that!
« Back”
False as I havent left a review. This site seems to be set up to do this on purpose if you are to leave a bad review.
The cake only smelled great, but ultimately it sank. Baked for 45 min on 175C, it started to get a bit too brown at the top for my liking. Used oven thermometer. At 45 min mark inserted toothpick, toothpick came out clear, and toothpick upon insertion showed how light and airy but moist the cake is and it was nicely risen but when taken out to cool and as it cooled it sank. Unsure why this happened. None of you reasons for why the cake sank are faulty in my case. Not even under/over mixing as I mixed for exact time as you have. All the ingredients except bananas were new, and were tested before using. I used scales for this recipe. Unsure what went wrong but probably wont try this recipe again.
Sam
Hi Paola! The reviews are legitimate. I see you have left the same comment multiple times with various stars. The fact that you left the identical comment multiple times is why you got the “duplicate comment” message (because you left multiple duplicate comments).
There’s no gimmick or game here, all of my comments are held for review before approval, this prevents spam messages as I get many (as in hundreds) of those every day and have to filter them. You’ve also commented on YouTube where I first answered your comment.
In case anyone else runs into this problem I would recommend (as I did on YouTube) simply baking for longer. If it sank and the leavening agents weren’t bad, everything else was followed to a “T” then the only thing that makes sense would be that the cake simply needed more time in the oven. You can see in the photos and the video that it should not sink after cooling, again, I’m not trying to fool anyone, the cake will not sink if prepared and baked properly and I have photographic and video evidence of that 😅. If it begins to brown before it’s finished baking, simply tent with foil as noted in the recipe. I hope this is helpful to someone 🙂
Kathy Stem
She should also check the actual oven temperature, using an oven thermometer. It may not be calibrated properly.

Sam, you are my first choice for all my baking adventures. Non bakers should understand baking is a science and the recipe should be followed exactly. Fact of life: sometimes you fail… try, try again.
No need to post multiple negative reviews. If you don’t like the recipe, keep it movin. You are great, Sam and EVERYTHING I have made with your recipe has blown the roof off.
Don’t let the haters win! You’re the BEST!
DETROIT LOVES YOU!!
Liz
great cake! easy, moist and tons of flavor.
Camille
Just made the banana cake. Most banana cakes, muffins, etc. just taste like banana bread to me. This one finally made a difference. The frosting is also the best cream cheese frosting I’ve made. I’m nearly 80 and a long time baker. I used chopped toasted pecans to top it. Pecans are about all I use…around 15 pounds a year. I did cut the baking time to 42 minutes. I hate to over bake anything I can always add time. I would send a picture if there was an option, but I’ll just sit here and eat my delicious cake at 10:40pm. 😋
Kristy
How would you suggest baking times if I wanted to use 8-9 inch circle pans to stack them for a tiered cake? Thank you!
Emily @ Sugar Spun Run
Hi Kristy! We’ve never baked this recipe in round pans, so we can’t say for sure. Just keep an eye on them and use the toothpick test for doneness 😊
Julie
Hi there, I’m planning on making this for my husband’s birthday. Banana cake is his favorite. I read somewhere else that if we stick it in the freezer immediately after taking it out of the oven it will help keep the moisture. Should I try this technique with this particular recipe, or will it make it TOO moist (since it is supposed to be a naturally moist cake)? I love to bake but am not a natural in the kitchen If you catch my drift 🙂
Sam
Hi Julie! This cake is very moist. I would be very hesitant to pull anything directly from the oven to the freezer. Enjoy! 🙂
Kenny
Hello Sam,
Looking forward to trying this recipe. I was wondering about adding crushed Oreo cookie bits into the batter and baking in a 6” round pan. Can you advise on the quantity of Oreo bits please?
Thank you.
Sam
Hi Kenny! If you are making the full batter you could probably break up and add about 20 oreos into the batter. This recipe will make enough for probably 4, 6″ cakes. 🙂
Debbie
Could I use castor sugar in place of granulated sugar
Emily @ Sugar Spun Run
Hi Debbie! That should work fine 😊
Abby
This cake was amazing!!! We ate it so fast! I am about to make it a second time. I especially liked the silky cream cheese frosting. I’ve never made frosting so smoothly. I don’t particularly like frosting but this one was divine. I look forward to trying more of your recites
Debbie
I need your help. I have been excelling the ripeness by brown bag and apple. Yesterday they spotted nicely, but I am sick. They s there any way to save even though they are brown now. I don’t want this to turn into banana bread. I please advise. The thank you!
Sam
Hi Debbie! Lots of people freeze their browned bananas to use later. I hope that helps!
Misty
Tasted delicious but I took it out to soon. The top was browning and the middle came out clean (I used a fork). While I let it cool the middle sank down & the middle was gooey. We ate around the gooeyness & it was delicious. Will make again soon! Just to note *I took it out a few minutes sooner (due to too browning) than the recommended time.
Emily @ Sugar Spun Run
Oh no! It can be tough to judge browning with banana breads/cakes. We are glad it still tasted good regardless 😊
Rachelle Bishop
I first made this for my son’s first birthday in January 2019. Since then this cake has been a staple in our household and a huge hit! Every year, I ask both my kids (now 5 and 7) what cake they want, the answer is always “banana cake!!”. Thank you for this awesome recipe, perfect as-is!!!
Emily @ Sugar Spun Run
That so sweet, Rachelle! We love that our recipe has become a tradition for your family ❤️
Maria B Rugolo
I increased this recipe by half, baking it in a 10x15x2 glass pan. Cooking time was 55 minutes, tenting it with foil at the 30-minute mark was necessary. I only had frozen bananas (over-ripe that I froze) which I defrosted in a sieve overnight to remove excess liquid (which was plentiful). I toasted walnuts and chopped them up to top off the amazingly delicious and creamy cream cheese frosting. This cake was moist and delicious and full of flavor as promised!
Sam
Thank you so much for trying my recipe and for sharing your notes, Maria! I’m so glad you enjoyed!
Mariah
Can this make a layer cake?
Sam
Hi Mariah! That should work just fine. 🙂
Gigi
So yummy! Added a teaspoon of cinnamon and about an eighth teaspoon of nutmeg for a bit of a banana bread flavor. Super moist cake and the frosting is so creamy and sweet. Will definitely make it again soon!
Kristy
Any idea if I can use 8 or 9 inch round pans instead of traditional rectangular size? If so how long is cooking time? Any tips?
Emily @ Sugar Spun Run
Hi Kristy! Either size will work fine here, but we’re not sure on cooking time. Enjoy!
