Banana bars with cream cheese frosting are the perfect combination of moist, tender banana bread and a rich, tangy frosting. These bars are incredibly easy to make and deliver the same comforting flavor as banana bread but in a lighter, more dessert-like form. The cream cheese frosting adds a luxurious, sweet touch that perfectly complements the soft, flavorful banana base, making these bars a crowd-pleaser for any occasion.
The key to these banana bars is the ripe bananas. Overripe bananas are ideal because they bring out the natural sweetness and moisture in the bars, ensuring a soft, tender texture. The banana flavor is front and center, but it’s balanced by the richness of the cream cheese frosting, which offers a tangy contrast that makes each bite even more indulgent.
The banana bar batter is simple, combining mashed bananas with sugar, eggs, butter, and flour. The addition of baking soda helps the bars rise, creating a light texture without being too dense. A pinch of salt and a hint of vanilla extract enhance the flavor, while cinnamon adds warmth and depth, though it’s optional. The batter is spread into a baking dish and baked until golden brown. Once cooled, the bars are ready for the frosting.
The cream cheese frosting is what truly elevates these banana bars. Made from cream cheese, butter, powdered sugar, and vanilla extract, it’s smooth, sweet, and creamy. The tanginess of the cream cheese perfectly balances the sweetness of the banana bars, creating a delightful contrast. For an extra touch, you can add a bit of lemon juice or zest to the frosting to give it a refreshing zing.
These banana bars with cream cheese frosting are incredibly versatile. They make a perfect dessert for family gatherings, potlucks, or even as an afternoon snack with a cup of coffee or tea. The bars can be made in advance and stored in the fridge, allowing the flavors to meld together even more.
Whether you’re a banana bread lover or someone who enjoys a sweet, creamy dessert, these banana bars are sure to be a hit. They are rich, moist, and bursting with banana flavor, all topped with a silky cream cheese frosting that makes them absolutely irresistible.

These banana bars are absolutely divine! The cream cheese frosting takes them over the top. Definitely a 5-star recipe!
I don’t care for bananas, but my friend made these and they were super good! Just have a sweet tooth, that’s all. 5/5!
Bananas or not, I guess if they taste good, that’s what matters! Glad your friend liked ’em! 🍌
Sweet tooth indeed! But I don’t see how banana can taste good… I need a proof next time. 🤷♂️
Yum! My kids loved these, but I think I used too many bananas. Next time I’ll stick to just two. But overall, they were a hit! 4 stars!
Tried it, but mine came out really dense. Maybe I mixed it too much? I don’t know. Just didn’t work for me. 2 stars.
I think you might’ve overmixed the batter! Just mix until it’s combined, and it should be lighter. Don’t lose hope, try again!
Pretty easy, but I needed closer to 30 minutes in my oven. Toothpick came out clean around then. Tasted great after chilling 1 hour.
I tried these but 25 min was way too short for me—more like 40. Also I didn’t have “ripe” bananas so I just used regular and it tasted kinda bland. Might try again though, frosting looks good.
Good to hear! Mine also runs a little longer at 350—oven temps vary so much. Chilling helps the frosting set up too. Thanks for sharing the timing.
Easy recipe, but mine came out kinda dry… Maybe I overcooked them?
Dry? Oh no! I just don’t get how that happens. Mine were super moist. Maybe use a bit more sour cream?
I think you might’ve baked them too long! Try checking them a few minutes early next time.
I substituted applesauce for butter and they turned out delish! Healthy yet yummy! 🥳
I don’t know, mine turned out kinda dry. Maybe I overbaked it? A bit disappointing.
I had high hopes, but the frosting was too sweet for my taste. Maybe less powdered sugar next time?
I think the sweetness is a big part of what makes frosting delicious! But yeah, you could always adjust it to your liking. Maybe try adding some lemon juice to balance it out?
Less sugar? Nah, I love it sweet! But I get it’s not for everyone. Just remember, the more sugar, the more fun! 😄
They were okay, but too sweet for my taste. The frosting was a bit much.
I had a similar recipe that used peanut butter instead of frosting, and it was way better!
Nah, cream cheese is the best! Peanut butter just makes it too heavy. Stick with the recipe!
Peanut butter sounds interesting, but cream cheese frosting has its charm! Can’t beat that tangy flavor!
These banana bars are sooo good! I can’t believe how moist they are. Definitely making these again!
I agree! These banana bars are the best! So fluffy and sweet! Can’t wait to share them with my friends.
They look good, but I’m not sure about the sour cream. Isn’t that for savory dishes? 🤔
These banana bars are a hit! So moist and creamy. My kids loved them!
My frosting was grainy for a minute until I beat longer. If anyone else has that issue, don’t panic—just keep mixing.
Yes!! Mine was grainy too at first. I almost gave up but kept beating and it turned smooth after a few more minutes. Good tip—thank you!
I thought I followed the recipe, but my frosting stayed kind of gritty. Maybe my cream cheese wasn’t soft enough? Also I beat it pretty briefly—oops. Still tasty though, just not pretty.
Delish!
My kids loved these! Perfect snack for their lunch boxes, will be a regular from now on.
I’m so glad your kids loved them! These bars are such a hit with my family too. Perfect for a sweet treat!
Really? Are they that good? I tried banana bars once and they were too mushy. I might pass on this one.
Not bad at all, but 25 minutes feels short. Also my banana bars stuck slightly even though I greased. Maybe parchment next time.
Can this be made with chocolate frosting? I don’t like cream cheese.
I tried it but the batter seemed too thick? also I used 9×13 but maybe my pan was deeper? Idk. They tasted good, just not the texture I expected.
Ooh that makes sense. If your pan was deeper (or your bananas were more mashed than usual), it can make the bars bake up tighter and the batter feel thicker. Next time, try adding 1–2 tbsp sour cream or a splash of milk to loosen it just a bit—also make sure you only mix the flour in until combined (overmixing can make it thick/dense).
I’m pretty sure 25 min is too short for 9×13—if it’s deeper it needs longer. Mine were kinda gummy until I baked like 35-40 min and checked with a toothpick. But hey, if they tasted good, you’re not far off. Maybe don’t add more liquid though… just cook longer lol.
Easy to follow! I made these for my book club and everyone couldn’t get enough! Will make again!
I also made these and they were a hit! So easy and delicious. Thanks for sharing!
They look good but I wonder if they really taste as good as the picture. Has anyone tried substituting the sour cream?
Bananas?! YUCK! Who puts bananas in bars? Not for me. 😒
Bananas are the best! They make everything moist and sweet. You should give it a try! 🍌
Yea, bananas in a dessert kinda weird. I don’t get it either. How can you like banana bars? 🤔
Bar bananas good!! I love them, my grandma makes them too.
Good! My dog loved it too. 😂
Who put sour cream in a banana bar? Sounds weird, but I’ll give it a try I guess.
These banana bars are amazing! So moist and tasty! A definite hit at my party!
I totally agree! These bars are so good, my kids couldn’t get enough of them!
Do you have to use sour cream? Can I use yogurt? I wanna make these but scared to mess it up!
These turned out super moist and the banana flavor is spot on. I added a pinch of cinnamon too—highly recommend. Frosting was creamy and not overly sweet for me. Yum!
Made these tonight—so moist! The banana flavor is spot on, and the frosting is dangerously good. I used extra vanilla just because. Will bake again.
I tried these and they turned out kind of dry. Not sure what I did wrong.
Maybe you overbaked them? The time can vary a lot based on your oven! Try checking a few minutes earlier next time.
Is 350°F really the right temp? That seems high for banana bars…
Yummm!! I can’t stop eating them! Even my kids loved them!
They are good, but I didn’t really like the sour cream in it. Maybe I’ll try without it next time.
That’s awesome! I made these for a potluck and they disappeared super fast! The creamy frosting is the best part.
Can I use almond flour instead of regular flour? Asking for a friend.
Wow. Banana bars like dessert-cake vibes. I shared them and everyone asked for the recipe. Will make again for sure!
Right?! The cream cheese frosting really makes it taste like real dessert. 😄 Thanks for sharing—hope it turns out awesome when you make it again!
My kids devoured these! Easy recipe and I love the cream cheese frostin’. Definitely making again!
I had high hopes but they turned out a bit dry. Not sure what I did wrong.
Cream cheese frosting is where it’s at. I’m usually skeptical about powdered sugar frosting but this one tastes legit. Next time I’ll make it thicker by using a bit less sour cream in the base.
Honestly, not for me. Bananas and frosting? What’s the deal with that??
Pretty good! I can’t believe how easy it was to make them. Will make again!
I totally agree! These banana bars are super easy and they taste amazing! Glad you enjoyed them!
Really? They seemed a bit complicated to me. Did you find any tricky parts?
I’m not a big fan of bananas, but these bars are surprisingly delicious!
Honestly I was skeptical about mixing sour cream + bananas but wow. Texture is like a dense but tender cake bar. Frosting came out smooth.
I was skeptical too—bananas + sour cream sounds kinda weird—but your results sound exactly like what I want. Good call letting it cool completely before frosting!
