If you’re a fan of classic upside-down cake and also happen to love chocolate, this chocolate banana upside down cake might just be your new go-to dessert. It’s nostalgic, rich, and comforting, with a twist. Instead of the usual pineapple topping, ripe bananas are caramelized in butter and brown sugar, then crowned with a soft, chocolatey cake that stays moist for days.
The magic starts with the base (which becomes the top once inverted): slices of ripe bananas nestled in a pool of melted butter and brown sugar. As the cake bakes, the bananas soften and the sugar caramelizes, creating a glossy, golden topping that’s both sweet and sticky. The contrast of the rich chocolate cake against the tender bananas is a perfect marriage of flavors—bittersweet meets tropical sweetness.
This cake is also a wonderful way to use up bananas that are just a bit too ripe for snacking but perfect for baking. The riper they are, the more flavor they’ll bring to the top layer. The batter comes together easily with pantry staples: cocoa powder, flour, eggs, butter, and a touch of vanilla. For an extra decadent version, try folding in chocolate chips or a handful of chopped walnuts.
When it’s time to flip the cake out of the pan, don’t stress. Just let it cool slightly, run a knife around the edges, and invert it confidently onto a serving plate. The aroma alone, warm banana caramel and deep cocoa, is worth the effort.
Serve it warm with a scoop of vanilla ice cream, a dollop of whipped cream, or just as it is. It’s the kind of dessert that doesn’t need much dressing up to make an impression. Whether you’re baking for guests or just indulging yourself, this chocolate banana upside down cake is a sure crowd-pleaser.

I tried this but it came out super soggy. Not sure what I did wrong 😕.
This cake is amazing! So moist and the bananas are divine!
Yummy!!! Best cake ever! So good I ate half. 😋
I substituted almond milk for buttermilk, and it didn’t taste right. Stick to the recipe!
I don’t like bananas. Can I use apples instead? Just wondering.
Using apples sounds like a great idea! It’ll give it a different flavor but still be yummy. Let us know how it turns out!
Tastes like heaven! My family couldn’t get enough of it. Will definitely make again! 🍌🍫
LOL, upside down cake?? I just flipped it and made it right side up! 😂
Really easy to follow tho I messed up the caramel; it burnt! I’ll try again.
Nice cake!
Too many steps!! I’m just gonna buy a cake next time. 🙄
I understand! But the steps really make it worth it. This cake is so delicious! 😍
Too complicated!! Who has time for all that? I’ll just buy a cake from the store. 🙄
Yummy! But what is 350°F? I just used high heat, lol. It works too!
LOL, high heat works too? That’s kinda brave! I always follow the temp exactly, but glad it turned out yummy for you! 🌟
350°F is important! If you use high heat, the cake might burn or not cook good inside. Just sayin’.
Wow. So good. So sweet. I want more! 🍌🍫
I totally agree! This cake is just the best. Can’t wait to bake it again!
Easy to make! I didn’t have buttermilk, so I used regular milk with a bit of vinegar instead. Still turned out great!
Heard bananas r bad for dogs? Idk, but maybe leave it out for them. Cake was alright tho.
Best cake ever, OMG!!! I Made it for my friend’s birthday and everyone loved!
Flop! My cake came out super dense. I think I messed up somewhere. Any tips for fluffier cake?
I followed the recipe but the cake turned out a bit dry. Maybe I overcooked it. Not sure I’ll try again.
Maybe try reducing the baking time next time? Sounds like a yummy recipe otherwise!
I think you probably did it wrong. I never have dry cake when I make this! 🤷♂️
Eh, I’m not so sure about the buttermilk part. Why not just use regular milk? Can anyone explain?
I think buttermilk adds a richer flavor and makes the cake super moist! Regular milk won’t do the same. Trust the recipe!
Nah, not for me. Too sweet and sticky. Not a big fan of banana either.
I get that! Bananas can be super polarizing. Have you tried it with other fruits instead? Maybe apples or berries would work better for you!
Bananas should be green for this right? I used ripe ones and it was too mushy.
Yum! Can’t believe I’ve never tried upside down cake before! This is way better than I imagined.
Easy to make but mine collapsed. Is it supposed to do that? Help!
Chocolate and banana? Perfection! My family loved it. A big success at our dinner party.
Yummy! I loved the caramel! Definitely a keeper for family gatherings. Thxs for sharing!
Not what I expected. It was a bit too rich for my taste. Maybe less cocoa next time? But good idea.
I tried making this and it turned out a bit soggy. Maybe I added too much buttermilk?
Yuck. My cake fell apart when I flipped it. Guess I need to practice. Lol.
Banana and chocolate together? Sounds weird but it was surprisingly good.
Not sure if I liked it. The texture felt off, and I thought it needed more chocolate. But my kids gobbled it up.
Good cake, but doesn’t taste like a cake. More like a pudding. Still kind of good tho.
I kinda agree, it’s more pudding-y for sure! But I love banana stuff, so it works for me.
Isn’t cake supposed to be cake? If it ain’t, I wouldn’t call it cake! But hey, if you like it, that’s what matters.
This cake is amazing! I made it for a family gathering and everyone loved it. It was gone in minutes!
This looks absolutely delicious! Can’t wait to try it out this weekend!
This cake was absolutely delicious! The caramelized bananas on top just made it heavenly. Definitely a keeper!
I’m so glad you enjoyed it! The caramelized bananas really do take it to another level. What a brilliant idea to try this recipe!
It sounds good, but I’m not sure about the chocolate and bananas together. Seems like a weird combo to me.
Wow, never thought of putting bananas and chocolate together like this. Who knew?!
I tried this recipe, but the cake turned out too dry. Maybe I overbaked it? Not sure if I’ll try again.
I dunno, I think my cake turned out a bit too soggy. Maybe I added too much buttermilk? Not sure if I’ll make it again.
Uhh, so confused. Can I use green bananas? I might have that in my kitchen…😅
Why not? Just use what you got! May taste a bit different, but who cares. 😂
I think you should use ripe bananas for this recipe. Green bananas might not caramelize well. Just a thought! 🍌
So easy to make! Even my 10-year-old helped. Great family recipe!
This cake was an absolute hit at my family gathering! Super moist and flavorful. We loved the caramelized bananas on top!
This is a cake?? More like a banana disaster for me. No offense! But it just didn’t work out. 🙁
This cake was delicious! The bananas caramelized perfectly. Will make again!
I tried making this and it flopped big time. The bananas burned and the cake was dry. Shouldn’t be that hard, right? 😒
I’m glad you enjoyed it! The caramelized bananas can really take it to the next level. Did you add any nuts? I think that would make it even better!
Used margarine instead of butter, came out okay. Maybe a bit less sweet. Did anyone else try that?
I followed the recipe and it turned out great! But my friend thought it was too sweet. Guess taste varies.
Bananas ruin every dessert. Chocolate should be solo! 1 star.
I tried making this but ended up with burnt bananas… Whoops! Maybe I need to watch the oven more closely next time!
This cake is so easy, I made it with my kids. They loved smearing the batter everywhere! 😂
Yum! I added nuts to the topping and it was a hit! Can’t wait to make it again.
I thought this would be healthier since it has bananas, but it’s full of sugar! Next time, I’ll decrease the sugar.
Yeah, sugar sneaks up on ya, right? But it’s a dessert, so I kinda expect it. Maybe use less sugar next time like you said!
I don’t get why you thought it would be healthy. It’s cake! Cake has sugar. Just enjoy it, it’s delish!

I think the recipe is missing something. It was kinda dry and not super sweet.
I totally get what you mean! I found it a bit dry too. Maybe try adding more bananas or a bit of yogurt next time for extra moisture!
This cake is absolutely heavenly! The caramelized bananas on top are to die for!
I dunno, caramelized bananas? Sounds weird. What if they turn mushy? 🤔
Totally agree! The bananas make it so much better! I can’t wait to try making it myself!
Yum!!! Chocolate and banana are a perfect combo. My kids loved it!
That’s awesome! I love how kids can try new things and enjoy them. Makes cooking worth it! 😊
Is it really an upside down cake if it’s right side up? Asking for a friend. 😂
That’s a good question! 😄 Technically, it becomes upside down when you flip it, right? But I get what you’re saying!
Yum! Can’t believe how easy it was to make. Tastes just like heaven! 😍
I tried this recipe and it was a disaster! The cake didn’t rise at all. 😩
Cake wasn’t bad but I guess I expected something different? Like more chocolatey? 🤷♂️
Wow! This tastes like heaven! I couldn’t stop eating it! Definitely a keeper in my recipe book.
What’s the deal with the bananas? I used a different fruit instead and it was gross. This recipe is misleading!
I tried it but something went wrong. The bananas were mushy and the cake was too dry. Not sure if I did it right.
I didn’t have buttermilk, so I used yogurt instead. Cake still tasted amazing! Thanks for the recipe!
So good! I didn’t have buttermilk, so I used regular milk and it still turned out great!
This cake was a hit at my party! Everyone loved it! Totally making it again.
That’s awesome! I’m so glad it was a hit! I plan to try it this weekend. Any tips?
This cake is absolutely heavenly! The caramelized bananas on top are a game changer. Will definitely make again!
I have a question, can I use different type of bananas? Or does it have to be the type? Idk!
Is it really upside down? My cake went sideways… 😂 Good flavor tho.
I don’t know, the bananas turned brown too fast. Not sure if it’s worth the fuss.
I hear ya! Bananas do that sometimes. Maybe try using firmer ones next time?
Eh, I don’t get the hype. Tasted too much like banana bread but with chocolate.
Did I do something wrong? Mine didn’t rise much at all. Had to throw it away. 🙁
