If you know me, then you know that I have a true love for a good layer cake. I find them beautiful, delicious, and at times a challenge to photograph. But I always end up loving them. I would say that nine and a half times out of ten, if you ask me to bake a cake, it will be a layer cake. If I’m baking for a chocolate lover, I turn to my standard three-layer chocolate cake. If It’s someone who really appreciates a fruit cake, this blackberry lavender naked cake is my favorite. And if it’s Easter? I’ll bake this layered coconut carrot cake from the HBH Super Simple cookbook (or maybe this lemon coconut naked cake, depends on my mood).

Yes, it’s safe to say that layer cakes are what I am passionate about when it comes to cakes. That’s probably why I’ve avoided making sheet cakes for the longest time. They just never excited me like a layer cake does. But that all changed the minute I made this banana cake. It’s one of my better cakes for sure. So super simple. And so insanely delicious.

I cannot wait to tell you guys about it. This cake is SO GOOD.

What’s the reason for cake?

Well, you never need a reason for cake, it’s always good, and always welcome, but I will say my dad’s birthday was the inspiration behind this recipe.

As you all know, I love cooking and baking for people. It’s why I got into cooking in the first place. So whenever it’s someone’s birthday I love cooking and baking with the foods they love most. Two of my dad’s favorite foods? Bananas and chocolate. He loves them separately, but he loves them paired together even more.

Enter this cake. It’s moist, a touch coconutty, heavy on the bananas, and topped with a very generous spread of chocolate frosting. My banana bread recipe is probably in his top ten favorites when it comes to my baking. And I get the feeling this cake just made his list too. Why? The frosting, it’s to die for.

Here is how you make this banana cake.

This is VERY easy. The cake itself is made in just one bowl and comes together in no time at all.

Step One

Let’s start with the banana coconut sheet cake.

Find yourself some very ripe bananas, I’m talking practically black bananas everyone. Very, very brown bananas are KEY to keeping the cake, flavorful, sweet, and incredibly moist.

Mash up the bananas and then mix with a little coconut oil, honey, a couple of eggs, and a splash of vanilla. Add flour, a pinch of cinnamon (only if you wish), and a dash of salt. Stir in some shredded coconut. Maybe a bit more for that extra coconut flavor. The coconut is that unexpected ingredient that makes the cake really good. It’s subtle enough that you can barely tell it’s there, but it adds a special touch. Pour batter into the 8-inch square baking pan.

Step Two

Bake, and less than 30 minutes later your house is going to smell incredible. Nothing smells better than a banana cake baking. Stick a fork or toothpick into the cake and see if it comes out clean to ensure it’s baked completely!

Step Three

Now, to make that fudgy chocolate frosting.

No cake is complete without frosting, and a banana cake requires a simple chocolate frosting.

I wanted mine to be extra light and whipped, so I incorporated a bit of cream cheese and used plenty of cocoa powder, plus vanilla extract too. My real secret for this frosting however? Salted butter…it’s that ingredient that will make your frosting better than everyone else’s. Trust me. The touch of extra salt goes a long way.

Once the cake is out of the oven, let it cool for thirty minutes or so, then frost, snack, and enjoy! Love the fluffy texture of this cake and the delicious chocolate frosting.

This makes for a delicious afternoon treat or late night dessert but is equally great as a simple birthday cake. It’s no fuss, pretty, and so good. The best part? This cake can be baked, frosted, and ready for eating in really just about an hour. If you need to get the cake to cool quickly, just pop it in the freezer to chill off, then frost. I understand if you need to try a bite…right away. The cake just smells and looks too good, it’s a hard one to resist.

So with that. How about some Friday night baking? I think we should! And please, please share on Instagram so I can see!! Can’t wait. ENJOY!!

Ingredients

Chocolate Fudge Frosting

Instructions

  • 1. Preheat oven to 350 degrees F. Grease an 8-inch square baking pan. Line with parchment paper.
    2. In a large mixing bowl, stir together the mashed bananas, coconut oil, honey, eggs, and vanilla until combined. Add the flour, baking soda, cinnamon, and salt, mix until just combined. Fold in the coconut flakes. Pour the batter into the prepared bread pan. Bake for 30-40 minutes, or until center is just set. Remove and let cool for at least 30 minutes before frosting.
    3. To make the frosting, add the cream cheese and butter to a large mixing bowl. Using an electric mixer beat until light and fluffy, about 2 minutes. Add the powdered sugar, cocoa powder, and vanilla. Beat another 2-4 minutes or until the frosting is light and fluffy. Beat in the coconut cream until combined. 
    3. Spread the frosting over cake. Slice, snack, and enjoy!

Notes

To Make Gluten Free: Use an equal amount of your favorite gluten free flour blend in place of the all-purpose flour. I recommend Cup4Cup gluten free flour
To Replace Coconut Oil: use an equal amount of olive oil, melted butter, or canola oil.
Storing: this cake keeps well for 3-4 days at room temperature. 
To cool cake quickly for frosting: place in freezer for 15 minutes. Remove and frost.

    I had the IG reel about this cake saved for 2 years and finally made it yesterday. Neither the cake nor the frosting was as light and fluffy as it appeared on video, so while the cake was fine, I felt that it was a let down since it was much more dense and thick than the video portrayed.

    1. Hi Holly,
      Thanks for trying this cake and sharing your feedback, sorry to hear you didn’t love it. Is there anything you may have adjusted in the recipe? Please let me know how I can help! xx

    This dessert was a big hit for my two daughters-in-law’s birthday celebration during our family vacation. Both of the ladies wanted different desserts – one asked for a double-layer chocolate cake and the other requested a Banana Cream Pie. I decided to compromise and pre-make the Easy Coconut Banana Chocolate Fudge cake at home, wrapped it in plastic wrap, and made the frosting ahead of time. When we arrived at the farm, I assembled the cake by splitting it into two layers, spreading Vanilla Creme between the layers, frosting it, and then placing it in the refrigerator. I took it out of the fridge before dinner to unchill a bit. It was a big hit. The best part is no leftovers! Berry cobbler the next night!! 🥰

    1. Hey Kym,
      Thanks so much for making this recipe and sharing your feedback, love to hear that it was enjoyed! Have a great 4th of July! xT

    I made this cake and the Zucchini Banana cake for a group function and everyone loved them! This is a perfect banana coconut flavour and so tender & moist

    1. Hey Heidi,
      Happy Friday!! I am so glad to hear this recipe was a hit, thanks a lot for trying it and your comment:)

  5. I love this recipe and am wondering if these could be made into mini cupcakes. If so, how long would you recommend baking?

      1. I just made these into mini cupcakes and they came out beautiful!!!

        My only suggestion would be to chop up your coconut flakes if the coconut pieces are large. (I used Trader Joes unsweetened coconut flakes and they were stringy lol)

        side note I also subbed the honey for date syrup (b/c I was trying to make some of it vegan friendly) and it was a great substitute!!! I can’t wait to make these again!

        1. Thanks so much for sharing, Sheena!! Such a great idea and I’m so glad they turned out well for you! xT

    I followed the recipe exactly and it was perfection! I was a tad worried while mixing the frosting, but when I added the coconut milk it came together beautifully and so fluffy ❤️ thanks for this one, it was my husband’s birthday and he loved it !

  7. Looking forward to trying this cake. I just want to confirm a bread (loaf) pan should be used and not an 8×8 pan?

    Thanks!

    I made this cake and set the timer for 30mins of baking. The fragrant smell of coconut and banana signaled to me that the cake was done even before 30min. It was a bit dry so next time will shorten cooking time to 25mins. The icing was good and not too sweet. Will make again.

  9. Hi Tieghan!

    Love all your recipes! I’d like to make this tonight and I have a ton of frozen ripe bananas in the freezer. Is it ok to use frozen ones for the recipe? Do I need to drain any juices from the bananas if I do use frozen? Thanks so much!

    1. Made this tonight for dessert along with your Spicy Pesto Pasta Alla Vodka. OMG it was all delicious and a hit with the family. Thank you for creating easy, flavorful and healthy recipes.
