Banana Cake with Buttercream Frosting (+Video)
This Homemade Banana Cake with frosting is made totally from scratch and has the best banana flavor ever! So moist and delicious!
A MOIST, FLAVORFUL HOMEMADE BANANA CAKE
I buy bananas like crazy. Every time I go to the store, I pick up a bunch. Mainly because my son and husband love them. Also because they can never eat them as fast as I buy them so I have excuses to make yummy goodness like Banana Bread or Banana Bread Crumb Cake and this Homemade Banana Cake with Vanilla Frosting.
TIPS FOR MAKING BANANA CAKE:
- The riper the banana, the sweeter the cake! Keep that in mind whenever you make any baked goods with bananas. If they haven’t started to brown then your bread or cake won’t be as sweet.
- Try adding a touch of rum extract to the batter or to the frosting to create a flavor similar to Bananas Foster.
INGREDIENTS NEEDED: (FULL RECIPE AT THE BOTTOM OF THE POST)
- sugar
- sour cream
- eggs
- salted butter
- super ripe bananas (a lot of brown spots)
- vanilla extract
- all-purpose flour
- baking soda
- chopped walnuts
- heavy cream
- powdered sugar
HOW TO MAKE BANANA CAKE:
Preheat the oven to 375F degrees. Spray 9×13-inch baking dish with nonstick cooking spray. In a medium bowl, cream together sugar, sour cream, egg, and melted butter.
Add mashed bananas and vanilla extract.
Add flour, salt, and baking soda; mix well
Pour into greased pan.
Bake for 25-35 minutes until a toothpick inserted in the center comes out clean. Cool completely before frosting.
To make frosting:
Cream butter and confectioner’s sugar together until smooth. Slowly add the heavy cream; stir until smooth. Stir in vanilla extract. Spread on cooled cake.
Cook’s Note: The frosting really is optional in this. This cake is so moist and is plenty sweet all by itself. It will be more like a snack cake without the frosting.
Like cream cheese frosting? Try adding 1/2 block (4 oz.) of softened cream cheese to the frosting mixture, adding a little more milk or heavy cream if necessary to make it spreadable.

I haven’t done much baking during our COVID-19 stay at home order. Had some ripe bananas and the first thing I thought of was cake. It is a delicious cake made with things I didn’t have to risk going to the store for. Thanks for the recipe. My husband and I are enjoying the cake with a lovely cup of coffee.
Hi there! I was wondering— could you give a measurement for the amount of mashed banana? Like in general, when you make this cake to perfection, how many cups/grams/oz would you say the amount of banana comes to? I’m always afraid of recipes that just state the number of bananas because even with the “medium” descriptor— I fear it will vary.
Hi Michelle, you can’t really mess it up if you overuse the mashed bananas. The real key is to make sure they are very ripe. I’ve never actually measured the bananas. I’ll try to do that the next time I make it! 🙂
BEST Banana cake Ever
Woo hoo!! Thanks so much Adrienne!
So, so good!!
You forgot to tell us in the directions when to put in the walnuts. I substituted pecans as I had a lot of them. I ground them in a food grinder first and then folded them into the batter after it was all mixed in my Kitchen Aid Stand Alone Mixer.
Usually add-ins are folded into the batter last as to not over work the batter and adding too much bulk so that the dry ingredients won’t incorporate with the wet properly and develop gluten from over mixing. And you should fold them in by hand.
It’s a great cake but the cooking time isn’t right…it took 50 min here…
This is the best cake ever.told son inlaw i was making it again,and didnt have time that day. He was really upset.lol made it today.tu very much for the keeper recipie. P.s hubbie loves it too!

Thank you for sharing this recipe. The cake is amazing and I'm in love :)))!
I think I'll try it with a peanut butter cream cheese frosting, THANKS for the site and the great & easy to read and follow recipes!
2 Thumbs up!!
My mother and i tried this recipe because we had so many ripe bananas laying around and we wanted to get rid of them, it's amazing! thank you so much for this recipe, it will be made a million times!
This looks nice and easy. I do not have any bananas at the moment, but will buy some extra to ripen especially for cake. When we were growing up our neighbor made banana cake all the time and she always put a caramel icing on it. Lots of different ways to top it.
Must try this recipe. It sounds delicious. My mom always made banana cake with a pink butter icing made with chopped marachino cherries and some of the cherry syrup for colour. Wonderful memories… Thank you!
I am a big fan of moist cake and bananas, so this recipe is a hit! Made it this afternoon and the frosting will be put on the cake tomorrow. If there is any cake left by then remains to be seen.
I am so so glad that you are sharing this wonderful easy recipe, just like all the other recipes you have. This sounds so great and I will be making it for my husband's bday next month. I am really glad to have found this blog site of yours. Thank you Brandie, you are making my cooking days happier with your recipes.
