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.

Lise
Just wondering if you don’t have buttermilk can I use sour cream instead
Emily @ Sugar Spun Run
You could, but you’d need to thin it out. Or you could just use our buttermilk substitute 🙂
Jo Scott
Question, how long in the oven for cupcakes?
Sam
I would recommend following my banana cupcake recipe. 🙂
Teresa
Does this cake need to be refrigerated because of the cream cheese frosting?
Emily @ Sugar Spun Run
Hi Teresa! This cake can sit out for a few hours but ultimately needs to be stored in the fridge. Hope that helps!
Susanne
I’m making this recipe and want to bake it using the 12-count brownie baking pan, how long would you recommend baking? Would it follow more along the lines of cupcakes, 20-25 minutes?
Emily @ Sugar Spun Run
Hi Susanne! Honestly without trying it ourselves we’re not sure how long it would take. We’d just recommend keeping an eye on it and testing with a toothpick for doneness. Hope that helps! 😊
Rachelle Bishop
I have made this cake now about 6 or 7 times. My entire family loves it — including picky 3 and 6 years olds. Every time it’s come out perfect. Perfect balance. This time we put half in some fun Star Wars shaped cake tins… curious if you think there is some glaze we could put on top to not hide the Star Wars characters faces…? Thank you!!
Sam
Hi Rachelle! You could do a simple vanilla glaze, which is just powdered sugar, a splash of vanilla extract, and enough milk to thin it out. It won’t have quite the flavor of the regular frosting though. 🙂
Jacueline
You may want to put a warning sign at the top of your buttermilk substitute recipe. I put the whole cup in. UGH!
PERHAPS WARN: NEED ONLY 1/4 CUP
Sam
Hi Jacueline! I’m not sure that will work as the buttermilk substitute works for really any recipe that needs buttermilk. I do have 1/4c in the instructions for the banana cake though.
Ani
Hi! I just made this recipe!! I halved the recipe, but I accidentally added the full amount of buttermilk! 🙁 It turned out scrumptious, just super gooey (which could be a good thing). It had great flavor. Another winner!
Patti
OMG!!!I MADE THIS IN A BUNDT PAN. AWESOMELY AWESOME
Jackie Harvill
First I love your recipes! But I am older and now have diabetes. Wanted to ask if you were to ever make lower calories and sugar recipes Please let me and everyone know. For now I change using oat flour, applesauce for oil. And honey with very little real sugar.
Sam
I’m glad you still enjoy everything, Jackie! Unfortunately I’m not super familiar with the low sugar/calorie side of baking. I do appreciate feedback on how you do it so I can relay the information to others though. 🙂
Tammy

Thank you so much, Tammy! You should try our banana cupcakes and banana cream pie too 😊
Kat
Amazing!!
Sydney
Hello!! I just made a test cake with your recipe. I want to use this for a grooms cake. I did some cupcakes and OH MY GOSH it is delicious!! My question to you is, do you think this cake would hold up as a stacked cake. I want to do 2 or 3 layers.
Thank you for any advise!!
Sydney
Sam
I’m so glad you enjoyed it so much, Sydney! I think it would work being at least 2 layers, but I haven’t tried it to be sure. 🙂
SYDNEY L MACINTYRE
Thank you!! I made a 6″ tasting cake. I put a caramel sauce in between the layers and a chocolate ganache buttercream on the outside!! I hope he loves it!! Everyone at my house who tried the tester muffins loved them!!
Sam
That sounds so incredible! I’m so glad everyone enjoyed it, Sydney! 🙂
Alexis
Is there any way I can use something other than buttermilk? I mean, I just don’t have any on hand. Thank you in advance!
Sam
Hi Alexis! I do have a buttermilk substitute you can use. 🙂
Jessica
I keep powdered buttermilk on hand too and there are directions on the box for substituting for fresh. It has always worked for me!
Becky
Can you freeze this cake for later?
Sam
Hi Becky! Yes, that will be fine, enjoy! 🙂
Mary McMahon
As with all your recipes this was a winner. It is my husband’s new favorite. I have had great results with your muffin recipes, my favorite is blueberry. Thanks for all your hard work.

Kristin
Super delicious and a great way to use up overripe bananas. Made this for friends and family and got lots of compliments. Now I’m trying really hard not to eat the rest!
Evelyn
Thanks Sam for answering my comment, Can you tell me how much cake flour I would need if I use 3 round 8″ pans to make my cake. I trying to make a cake for my son this Saturday.
Sam
Hi Evelyn! You will need to increase the recipe by 50% so if using weights you’ll need 468g of cake flour. 🙂
