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.

I’m going to make this for Easter. And after reading some reviews, I may substitute plain apple sauce for the oil. And since I don’t use white flour, I’ll use coconut & almond flour. A little more healthier LOL Fingers crossed it turns out ok. Thanks for the recipe. Happy Easter!
Sam
I hope you love it! Let me know how it turns out! 🙂
Mika Darlene Pickard
My family, friends, and coworkers absolutely LOVED this cake!!!! I made it for my ex-boyfriend and he actually tried to eat the entire cake by himself!!! I love how moist and flavorful this cake is. And this icing, OMG!!!!! The icing is the best cream cheese icing I’ve ever made. WOW!!! Thanks so much for sharing this recipe!
Sam
I am so glad everyone enjoyed the cake so much, Mika! You can never go wrong with cream cheese frosting! 😉
Lidia Bayliss
Cake was tasty but too much fat (2-3 times other recipes). I’ll use half the amount next time and see how it turns out. The frosting was delicious, the best I’ve had. Thanks!
Mika Pickard
I cannot thank you for this recipe!!! The cake was super moist. And that fantastic icing!!! OMG!!!! I’ve received so many compliments on this recipe!!!!
P.s. Thanks so much for the information about using the foil to tent the cake. Thanks again!
Sam
I am so glad you enjoyed the cake, Mika! 🙂
Lori chesney
Why is there a choice of light or dark brown sugar? Which one should I use? What is the difference between the two when baking? Help me please!!!
Sam
Hi Lori! Either will work perfectly fine. Dark brown sugar lends a tad more moisture, richness, and color to the cake. I usually use whichever one I have on hand. I hope you love the cake 🙂
Galeb
I had several bananas I needed to use ASAP. I just usually make banana bread but I decided to look for a recipe that used a significant amount of bananas. Once I saw that this banana cake used a whole 2 cups of bananas, I decided to make it. It is delicious and full of banana flavor. I followed recipe exactly and was very pleased with the results. The addition of whipping cream to the frosting lightened the usually heavy cream cheese. I will make this again.
Sam
I am so glad you enjoyed the cake, Galeb! 🙂
Lorraine
Hi, I made this yesterday, but amended as i went, i didn’t put in the white sugar, only put in 120ml oil, my eggs were small and added another one, and added a bag of chocolate chips, I’ve never had so many complements on a cake before, but I did have a cunning plan which was to arrive with it just out of the oven, oh and I added apple pie spices though, I usually go by the recipes and hate people who tweak them, so sorry, but your muffins were fab, and this is another recipe to add to my growing collection,
Sam
I am so glad you enjoyed the cake, Lorraine! 🙂
Dawna Meier
Absolutely amazing. Super moist and delicious
Sam
I am so glad you enjoyed the cake, Dawna! 🙂
Midge
I made this cake on Saturday late in the afternoon. Today is Monday morning and the cake is gone.
My husband told me not to make it again, he can’t stop eating it. My son love it also. We all loved the cake.
I followed the receipt and it was the best cake I have ever made.
All because no one ate the bananas this week.
Thank you so much.
Sam
😂 Sounds like they secretly want another cake! 😉 I am so glad everyone enjoyed it. 🙂
Vandana
This is one hell of a recipe! I instinctively knew when I read the recipe that it is it! I read all the comments and became slightly skeptical about people saying it’s oily. I used exact measurements except I used 3 eggs. I added cinnamon. Instead of butter milk i used half cup milk and one lemon juice left unstirred for sometime. I made the exact icing but used a pinch of cream of tartar and a dash of coconut powder. This is s really really good recipe. It’s going to be my best banana cake ever!
Sam
Thank you so much! I am so glad you enjoyed the cake! 🙂
Claudia
Hallo Sam,

Sam
Hi Claudia! The metric size of a 9 x 13 inch pan is 33 x 23 x 5 cm. 🙂
Liz
Tasted awsome.. But my cake did not rise.. Everything was as per meaurement
Sam
Hi Liz! Could your baking powder or baking soda have been bad/expired? That might have kept the cake from rising. I’m glad you enjoyed the taste! 🙂
Kris Lutz
Sam, thank you so much for this fabulous recipe! My husband asked for a banana cake with cream cheese icing for his birthday. When I came across this recipe, I appreciated all your effort to perfect it. And all the comments were glowing. So I made it. Oh. My. Gosh. Fabulous! Moist, rich, banana taste; creamy icing; deliciousness. Thank you for helping me treat my husband on his birthday!
Sam
I am so glad you enjoyed it, Kris! 🙂
Carl
Taste ok but came out extremely oily. Might cut back on the oil next time. Made it once using measuring cups then again with weighed out ingredients and the same result.
Sam
Hmm I am disappointed to hear it was so oily. I will do some trouble shooting in my kitchen to see why that could have happened. 🙂
Aanchal Soni
My cake turned out a little sour in taste perhaps because of salt. Also it was too oily. Do we need to cut down butter or oil’s measure???
Can i skip salt the next time i try??
I used the exact measurements.
Sam
I wouldn’t recommend cutting down the salt, nor do i recommend cutting the butter or oil. I’m really not sure where the sour taste might’ve come from (not from the salt, though), if it was too oily I’m wondering if the flour may have not been measured properly, did you use cups or a scale?
Aanchal Soni
I used the scale. If I forget the salty taste, oil was dominating banana’s flavor.
Katt
So I love this recipe! I used salted butter and didn’t add any salt. For cake and frosting. Also the second time I baked this cake, I added a third egg and made it a two layer cake. The extra egg made it 👌. Moist and delicious. Not nearly as thick and dense as with only 2 eggs. Thanks for posting this recipe! Everyone asks for it now!
