This is the best easy, moist banana cake recipe, and it’s made completely from scratch! My recipe is perfectly balanced with extra bananas and complementary spices and it’s crowned with a silky smooth cream cheese frosting. This is the snack cake of your dreams!

An Easy, Moist Banana Cake Recipe
This banana cake recipe exist solely because so many of you wrote to tell me how much you loved my banana muffins (see, I don’t call them “the best” for nothing) and asked if you could use that recipe to make a cake. The translation from muffin to cake wasn’t perfect, so I headed to the kitchen and, well over a dozen well-browned bananas later, finally have a perfectly moist and yet fluffy version that I think you’ll love.
Why This Recipe Works:
- The bananas do the heavy lifting. Overripe bananas are of course key for intense flavor, but they’re also full of natural sugars and pectin. These help lock in moisture and create a plush, super moist crumb, without making the cake dense.
- Oil for moisture, butter for flavor. Just using butter can leave you with a dry cake, while the flavor can fall flat without it. A balance of both works great here: butter adds rich flavor and oil keeps the crumb tender longer (especially helpful if you refrigerate the cake!). There’s a reason I use this blend of the two in so many cake recipes, like my vanilla cake and chocolate cake recipe!
- Cream cheese frosting, balanced just right. Cream cheese frosting is good enough to eat on its own by the spoonful, but 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 really want to make this cake luxurious, try my cream cheese-based brown butter frosting!)
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!).
What You Need:

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), and it worked wonderfully. Let’s talk about a few of the key players:
- Bananas. For the best flavor & moistest cake, you should use ripe, spotty 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 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 depth of flavor, thanks to the molasses.
- 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 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 as it will yield the best texture.
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

- Mash the bananas! A potato masher or even just a fork works well. Try to mash out as many lumps as you can, but it’s OK that you won’t be able to get all of them.
- Beat together the sugars and butter. Look for a light, creamy, well-combined mixture, then stir in the oil until it’s well 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 (especially since you need to be quite light-handed in the next step.

- Whisk together the dry ingredients.
- Stir the dry ingredients into the wet. You want the ingredients to be thoroughly combined, but as with banana bread or pancakes, over-mixing can result in dense, dry results.
- Spread the batter evenly into a greased 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 not raw batter!).
Make the Frosting

- Combine (softened!) 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).
- Gradually add the powdered sugar until completely combined.
- Add the cream. If you want a thicker frosting, you can skip this step, but I like the looser, silky feel that adding a splash of cream adds.
- 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!) 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.
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 has more of a “let’s call this breakfast” energy. Banana cake 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.
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.

Dorothy Williams
Good morning,
I made this cake for my granddaughter’s birthday and it was great. Now my daughter wants cupcakes. Would there be any changes besides baking time?
Thanks,
Dot
Sam
Hi Dorothy! I actually have a banana cupcake recipe I would recommend following. ๐
Annette
Can I use low fat buttermilk? I can’t find full fat buttermilk anywhere. Absolutely love using your recipes. The recipes turn out perfectly every time.
Sam
Hi Annette! It’s not my preference, but if it’s all I had I think I would use it. Let me know how it goes. ๐
Stella
This was one of my favorite cakes ever and your brown butter frosting complemented it so perfectly! Thank you so much for such a wonderful recipe! Happy Easter!
Luann
There’s a lot of recipes that say they are the best. This is amazing
Emily @ Sugar Spun Run
We’re so happy it was a hit for you, Luann!
Koriann Baldwin
Could this cake be made in a 9 inch 2 layer cake? Don’t have a 9×13 pan.
Sam
Hi Koriann! That could work. You will likely want to increase the frosting a bit. I’m not sure on a bake time in 9 inch pans. ๐
Diana A Hall
can I use a Bundt pan
Sam
Hi Diana! I haven’t tried it, but it could potentially work. I’m not sure on a bake time though.
Eleni
Oh So Good!! I did switch out the vanilla for maple extract, my family ate it until they nearly popped :o)
Casey @ Sugar Spun Run
That sounds delicious, Eleni! We’re so glad you enjoyed them!
jackie newcomer
this cake is the best. want to know if i make a 9 X 13 double layer cake for a birthday will the frosting be enough to frost both layers or will I have to double the recipe? or 1 1/2 times it. Thanks Jackie
Sam
Hi Jackie! If you are doing a 2 layer 9 x 13 cake I would double to frosting to make sure you have enough. ๐
Marion M Edwards
this is the best banana cake ever
Maria B Rugolo
Rave reviews every time! I made this recipe in two 8″x2″ round pans and it’s sturdy, moist and delicious. I filled it with banana pudding and carmel and frosted with Italian meringue buttercream. held up beautifully. Your recipes are always the best!
Emily @ Sugar Spun Run
That sounds wonderful, Maria! Thanks for coming back to let us know how it went for you ๐
jackie newcomer
This cake was exactly as described, the cake of your dreams. Best banana cake I ever made or ate.Husband said it is a keeper the frosting was delicious too light and fluffy. My cake was done in 32 min. glad I checked before 45min. I was 56 grams short on the banana’s maybe that is why it was done sooner.
Will definitely be making again and again. Thanks for the recipe Jackie
Emily @ Sugar Spun Run
We are so happy you enjoyed it so much, Jackie! ๐ฉท
Ni
hi can I add in blueberries, would that work? how many can I add for the recipe?
Sam
I haven’t personally tried adding the blueberries here so I’m not sure how many to add and how much to add.
deb
could this recipe be halved for a 8×8 square pan, also will the banana cake still be good without the topping, thanks
Emily @ Sugar Spun Run
Hi Deb! That will work fine. It will be less sweet without the frosting, but you could always dust some powdered sugar on top after the cake cools to help with that ๐
Joy
How do I store this on the counter for 3 days if it has cream cheese frosting on it? Wonโt it go bad- or is the room temp storage for if I donโt put the frosting on top?
Sam
Hi Joy, I have storing instructions in the recipe card. I only recommend keeping at room temperature for a day.
Kristin
Hello Sam, I was considering making this for a birthday, do you think the cake would be just as good in 9 inch round layers? I was concerned with it possibly being more fragile than regular cakes. was going to pair it with your brown butter frosting. it’s delicious. I put it on your spice cake for my mother’s birthday and I ended up eating the third of leftover cake all by myself lol. thanks for great recipes!
Emily @ Sugar Spun Run
Hi Kristin! This recipe will work just fine in round pans. We love that frosting pairing! ๐ฅฐ
Ann
what if I don’t have buttermilk, will whole milk work the same?
Sam
Hi Ann! I would make my buttermilk substitute using the whole milk. ๐
Larry Borian
Dear Sam I would just like you to know that I have tried your banana cake recipe and it was a smash. Every one that tried loved it Thanks for the help and recipe i would also like to say i am stuck on using 13ร9 cake pans i have found some more cakes i would to make Would i half to right for cake mix for that pan THANKYOU Larry
Sam
Iโm so glad you enjoyed the banana cake so much, Larry! It really depends on the individual recipe. Typically a 2 layer 8 or 9 inch round cake will fit in a 9 x 13.
N.Porter
I made this cake a month ago and my family is still talking about it. It tasted like the perfect banana pudding but cake, if that makes sense. I’ll definitely be making this again.
Enriquetta Fernandez
Just pulled it out the oven – second time making it AND it’s perfect! Absolutely Delicious!
