banana cake with Nutella frosting ~ now how could that be bad?

This amazing banana layer cake was first posted on the Great Island site in 2013, and it’s been a powerful food memory for me personally ever since. The combination of the perfect moist banana cake with that rich chocolate hazelnut buttercream is out of this world good. The 2013 version was just a single layer, which was fine, but doubling it really turns a great cake into a spectacular cake. Any banana cake or Nutella lover would be proud to have this for their birthday.

banana cake with Nutella frosting shopping list

Lots, maybe most, of the desserts and sweets that come out of the Great Island kitchen are on the simple side. This one is more of a celebration dessert, and that’s ok, because sometimes that’s just what the occasion calls for. But all the ingredients here are pantry staples except the ground hazelnuts, the Nutella (depending on your pantry!) and the sour cream.

  • ripe bananas, about 6, which will be 3 cups after you mash them. This is the cake for those bananas that are so ripe and pungent you could swear you spilled a little bourbon into the batter. I like to wait till the last minute to use my bananas for cakes and breads ~ they get better with age, like fine wine or cheese…
  • granulated and brown sugar
  • vegetable oil
  • eggs
  • sour cream
  • all purpose flour
  • ground hazelnuts ~ find hazelnut meal or flour in well stocked grocery stores, or make your own by toasting and grinding hazelnuts.
  • baking soda and salt
  • vanilla extract

for the Nutella frosting

  • butter
  • Nutella ~ this is the reason you always want an extra jar of Nutella in the pantry.
  • sour cream ~ sour cream is in the cake and the frosting, so you know it’s going to be good 🙂
  • confectioner’s sugar
  • unsweetened cocoa powder
  • cream or milk to thin it down
  • vanilla extract

that Nutella frosting!

The Nutella in the frosting makes it extra glossy and gives it that elastic quality that makes dramatic swoops and swirls.

With a frosting this good, I might be tempted to say it’s the star of the show, but no, in this case it’s all about that combination. Banana and Nutella is a match made in heaven, who knew?

my best frosting making tip

You can make frosting in your full sized food processor the easy way with less mess, and better, silkier results. Just dump everything in and process until smooth. Taste and adjust as needed. The powdery mess in contained in the processor, and it’s so powerful you don’t have to sift your confectioner’s sugar, or even bring cream cheese to room temperature before using. Lumps don’t stand a chance!

banana cake with Nutella frosting FAQs

Can I use frozen bananas?

Yes, defrost them and mash well.

Can I make this cake in a 9×13 pan?

Yes, it should work well that way. You won’t need the full amount of frosting in that case.

Can I bake this in 8 inch pans?

There is too much batter for 8 inch pans, and three layers would be too tall for stability.

Can I make this as a single layer cake?

Yes, just halve the recipe.

What’s the best way to store this cake?

I store it on the counter for up to a day, under a cake dome. After that I would refrigerate it due to the sour cream component in the frosting.

Can I make this cake ahead?

I like to bake the layers the day before. I cool them completely and wrap in plastic wrap. The next day I throw together the frosting and assemble the cake.

Can I freeze this cake?

The layers will freeze well, just cool completely before freezing and wrap in plastic and then again in foil. Frost the cake before serving.

  • 2 9-inch non stick cake pans, at least 2 inches tall Do not use shallow pans for this cake, there is a lot of batter.


  • 3 cups well mashed bananas, about 6 medium bananas
  • 1 cup granulated sugar
  • 1 cup light brown sugar, lightly packed
  • 1 cup vegetable oil
  • 4 large eggs at room temperature
  • 1 cup sour cream
  • 2 teaspoons pure vanilla extract
  • 2 tsp baking soda
  • 1 tsp salt
  • 4 cups all-purpose flour
  • 2 cups ground hazelnuts or hazelnut meal

Nutella buttercream

  • 8 Tbsp unsalted butter, room temperature
  • 13 oz jar of Nutella
  • 1/2 cup sour cream
  • 1 tsp vanilla extract
  • 3 cups confectioner's sugar
  • 1/4 cup unsweetened cocoa powder
  • 1/4 cup heavy cream or milk


  • Set the oven to 350F. Lightly spray two 9-inch nonstick cake pans and line with circles of parchment at the bottom.
  • Cream the bananas and sugars together until smooth, then add the rest of the wet ingredients and beat until well mixed. Scrape down the bowl as needed.
  • With the mixer on low, add the baking soda and salt, then the flour, a cup at a time. Fold in the hazelnut meal. Be sure to scrape down the sides and bottom of the bowl well to ensure everything is incorporated.
  • Turn the batter into the prepared pans. Bake for about 40-45 minutes, until a toothpick inserted in the center comes out moist but does not have wet batter clinging to it.
  • Cool for 10 minutes in the pan, then remove the cake from the pan and continue to cool completely on a rack before frosting.
  • Frost the cool cake with Nutella frosting.

For the frosting:

  • Cream the butter, Nutella, sour cream, and vanilla, then beat in the sugar and cocoa powder. Mix in the heavy cream. The frosting should be thick and glossy, but spreadable. If you want to thin it down, add a bit more cream. If you want to thicken it, add a bit more sugar. Note: You can make frosting in your full sized food processor the easy way with less mess, and better, silkier results. Just dump everything in and process until smooth. Taste and adjust as needed.
  • Frost the cooled cake and enjoy!

    This looks delicious and I’m making it right now ! Will let you know how mine turns out ! Just a quick question – in the list of ingredients you list baking soda and in the detailed instructions it says baking powder. Should it be baking soda, and does it make a difference between the two ? Thanks so much ! Love your website with all the great recipes !

    Can another pan be used successfully such as a Wilton mini bundt or a 4cske cake pan? I wanted to include them on a gift tray. Thank you!!!

      I think that should work Kris, just watch your baking times with the smaller pans.

    Looks delicious — I’m going to give it a try this weekend. If I have hazelnut meal already, any idea what amount to substitute for the whole nuts?

      It would be 2 cups of hazelnut meal for the layer cake.

    Hi Aunt Sue!

    I made this cake for Bruno’s birthday a few days ago and it turned out so well! I Googled “banana cake with Nutella frosting” hoping to find a recipe I had used years ago, and was so sad when all I could find were sticky, gross-looking recipes. Then there was yours! It was perfect…thank you!!!

    Hi – made this cake yesterday and frosted it today. Help! My nutella buttercream is grainy! What did I do wrong? I looked for some remedy’s online, but just couldn’t get it right. Any tips would be appreciated! I finally gave up and slathered it on the cake only because it still tastes absolutely DELISH! People are just gonna have to get over the graininess! Can’t wait to dig into this cake later tonight!

      Hi Margaret— I can’t imagine why your frosting would be grainy. Did you use confectioner’s (aka powdered) sugar? And did you sift it? If you used regular sugar it might be grainy. Let me know if that helps!

    Hi Sue… Sounds amazing! Do you think there is enough batter for me to make this in a bundt pan? Also… I’m obsessed with Nutella but not hazelnuts (I know )…have you tried putting chocolate chips in the cake instead? I’m going to make this tomorrow so ill let you know how it turns out:)

      Hey Amanda— I haven’t tried this in a bundt pan, so I can’t say for sure. As far as the chocolate chips, I haven’t tried that, but why not?? Good luck!
