This is a cake made with bananas so ripe they don’t even need to be mashed. So 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.

How can it be that I’ve never made a Nutella frosting before? It’s such a no brainer. My recipe makes enough to frost the top and sides of the cake, if that’s your preference, but I like it piled high just on top. This frosting is a real winner. It would be perfect for all sorts of cakes and cupcakes, and it’s a nice change from the regular chocolate frosting that everyone expects on something like this.

The cake itself is a nice, moist cake with a pronounced banana flavor.

The Nutella buttercream inspired the toasted hazelnuts in the cake. I roasted and then ground them up so they echo the flavor of the Nutella and add a nice texture to the cake.

This is the kind of recipe that doesn’t require a lot of introduction, I mean, seriously, how bad could banana cake with Nutella buttercream frosting be?

The cake is adapted from one of Ina Garten’s (so you know it’s going to be good!), and the frosting is my own.

Definitely give this one a try, it’s swoon-worthy. And even if you have a favorite banana cake of your own, try topping it with this frosting, you won’t be disappointed.

Author Sue Moran


  • 9 inch springform pan, or 9 inch non stick cake pan


  • 3 ripe bananas mashed
  • 1/2 cup granulated sugar
  • 1/2 cup light brown sugar lightly packed
  • 1/2 cup vegetable oil
  • 2 large eggs room temperature
  • 1/2 cup sour cream or buttermilk
  • 1 teaspoon pure vanilla extract
  • 2 cups all-purpose flour
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 1 cup toasted hazelnuts measure before grinding finely ground

Nutella Buttercream

  • 4 Tbsp unsalted butter at room temperature
  • 1 13- oz jar of Nutella
  • 1 cup sifted confectioner's sugar
  • 4 to 6 Tbsp heavy cream or milk


  • Set the oven to 350F Grease a 9 inch springform pan or nonstick cake pan with a piece of parchment at the bottom.
  • To toast the hazelnuts, spread them out on a dry baking sheet and roast for 10 minutes the preheated oven. Let them cool, and grind in a food processor until finely ground. You could also use ready made hazelnut meal, which Trader Joe’s sometimes carries, as well as Whole Foods. You could also substitute walnuts.
  • Cream the bananas and sugars together until smooth and fluffy, then add the rest of the wet ingredients and beat until well mixed.
  • Whisk the dry ingredients together and add to the wet, mixing until just thoroughly combined.
  • Pour into the prepared pan. Bake for about 55 -60 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.
  • Frost the cool cake with Nutella Buttercream.

For the Buttercream:

  • Cream the butter and add the Nutella, sugar, and cream. Beat until smooth and spreadable. Add a little more cream or a little more sugar if necessary to get a good consistency.
  • Spread over the top of the cooled cake and enjoy!

    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?

    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 don’t think there’s enough batter for a regular sized bundt cake, but I’m sure if you watched the cooking time and are fine with it being half the height, it could be done. As far as the chocolate chips, I haven’t tried that, but why not?? Good luck!
