Frosted Banana Cake

A slice of Frosted Banana Cake, a yellow banana, sliced almonds, fork on a black dinner plate

Bananas, bananas, bananas. Somehow I always seem to end up with way too many stashed in the freezer. Probably because I insist on buying them at Costco since they’re around half the price of Safeway. And, I have good intentions of eating one or so a day, and counting on Alex to at least eat one or two, but it never happens before they go brown and mushy. So, the peels come off, they get thrown into freezer bags and saved for whenever I remember they’re there, which is a chore in and of itself. We’re just a couple months away from having a 3rd banana eater, so maybe then my freezer stash will diminish.

This cake is great. Not only is it delicious, but it uses up a whole 3 bananas!! Super moist and teeming with banana flavor. The frosting turned out amazing and brought the banana taste to another level. My cake stacking ability is severely lacking, so the sliced almonds helped beautify my endeavor :)

Frosted Banana Cake, adapted from The Only Bake Sale Cookbook You’ll Ever Need

2 cups all-purpose flour
1 3/4 teaspoons baking powder
1 teaspoon baking soda
1/2 teaspoon salt
1 1/4 cups sugar
1 cup mashed ripe bananas (about 2 medium)
1/2 cup unsalted butter, softened
1/2 cup buttermilk
2 eggs, lightly beaten
2 teaspoons vanilla

Heat the oven to 350 degrees. Grease and flour two 8-inch round cake pans.

Combine the flour, baking powder, baking soda and salt in a large bowl; stir to mix. Add the sugar, mashed bananas, butter and buttermilk. Using an electric mixer on medium speed, beat for 2 minutes. Add the eggs and vanilla and beat for 1 minute. Spread the batter evenly into the prepared pans, smoothing the tops with a rubber spatula.

Bake for 35 to 40 minutes, or until a toothpick inserted in the center comes out clean. Cool for 10 minutes in the pans on a wire rack, then remove the layers from the pans and cool completely on the wire rack before frosting.

Meanwhile, make the banana buttercream frosting…

Banana Buttercream Frosting

1/2 cup unsalted butter, softened
1/2 cup mashed rips banana (about 1 medium banana)
4 cups powdered sugar
1 tablespoon milk
1 teaspoon vanilla

Using an electric mixer on medium speed, cream the butter, mashed banana, and half of the powdered sugar until creamy. Add the milk and vanilla and beat until combined. With the mixer running, add the remaining powdered sugar, beating until smooth and creamy.

Frost the top of one cooled layer, then stack the 2nd layer on top. Frost the sides then the top of the cake and you’re ready to eat!

I really like banana cake! I was given an old family recipe years ago and it came with a caramel buttercream that no one could ever make so making a banana buttercream seems wonerful to put with it!

I usually think banana bread/cakes are kinda boring looking (though delicious!), but yours looks SO pretty and is very photogenic :) And I’m certain it’s also delicious!! :)

I adore bananas. Bananas in my cereal, bananas and peanut butter and toast, and of course banana cake. This looks delicious, I adore layer cakes, and I’m always looking for something more exciting than my typical vanilla. I’m sure that this was moist and flavorful. Thank you for sharing!

Nice website you have here. Great pictures too! I wanted to reach in and have a bite of that cake. :)

We almost always make banana cake or cupcakes with over ripe bananas. They freeze well, so usually there are a couple in the freezer waiting for a busy night. Your cake is lovely.

My husband and I both love banana bread, so I’m thinking I might have to try this for his birthday cake! Sounds and looks delicious!

I’ve never heard of banana buttercream before. That sounds delicious!

MMM!! Just the title had my interest! A perfect way to use up those bananas. Banana has been my daughter’s favorite since she was born, we are always collecting banana recipes. This one is a keeper!

This banana cake looks so moist and delcious. My grandma use to make an awesome banana cake, I have never tried one myself. I always have bananas hanging around my kitchen. I bookmarked this one, I think it would be great for thanksgiving (if I can wait that long)! :)

I love banana cake. My mum always makes it when she has old looking bananas and I always make sure I’m around. I really like the idea of icing it! It looks lovely.

That looks great!

That looks reeeeeally delicious. I would take just a big bowl of the frosting, and a spoon, or maybe just my finger, and it would be treat enough.

I’ve sent you a couple emails (I hope you’ve gotten them). I adore your blog and was hoping to spotlight you in an online magazine I’m starting. Let me know if it’s ok to do a feature on your blog in the first issue that comes out on November 1st. Thanks!!!

Can you tell me how much baking soda and butter needs to be added. They are not listed to how much only tells me to combine and mix them. I am ready to bake and try this cake, it looks so yummy!!! Thanks

Thanks for catching that! I updated the recipe (sorry it’s taken me so long to respond…I had a long vacay…) and I hope you’re still able to try this out!
