Banana Cake recipe with cinnamon buttercream frosting

Can we talk about bananas for a sec? I love bananas every which way you can eat them.

Plain, in yogurt, dipped in chocolate, smothered in peanut butter, blended into a smoothie. . . . You get the point.

I also love cake. And, most of all, I love frosting. So, banana cake covered with fluffy cinnamon buttercream is right up my alley! 

Banana Cake

As much as I love banana everything, I have a gripe with some banana cakes. Too many are just banana bread recipes baked up in a cake pan and renamed.

Don’t get me wrong! I adore a good banana bread in all its variations from Classic Banana Bread to Nutella Swirled Banana Bread. A loaf never lasts long in my house!

That said, when I want cake I want CAKE. I want it to be moist, sweet, rich and (usually) covered in frosting. A good banana cake has to be worthy of its status as “dessert.”

Let me tell you, folks. This Banana Cake recipe, well, takes the cake!

Made with plenty of ripe bananas and butter, you get rich banana flavor in every bite.

Then, there’s the frosting–fluffy buttercream whipped with a pinch of cinnamon to add the best possible finishing touch to banana cake. It’s a great option to bake ahead of time, too!

How to Make Banana Layer Cake

I made this banana cake in layer pans. You could certainly make it in a square cake pan instead but I like to layer for one very important reason: more frosting per square inch!

To make the cake, beat butter, sugar, eggs and vanilla together, then just toss your ripe bananas into the bowl. You can mash them first if you prefer but I usually don’t bother. (Why get an extra bowl dirty if you don’t need to, am I right?)

From there, add flour, baking powder and baking soda and the cake batter is ready to go in the oven! Divide it evenly between your two greased and floured layer pans and bake.

While the cakes are cooling, I make the frosting from scratch.

Cinnamon Buttercream Frosting

Based on my go-to vanilla buttercream, this frosting is lightly kissed with cinnamon!

Just beat butter, powdered sugar, vanilla and milk in your mixer with a pinch of ground cinnamon. I use my whisk attachment or electric beaters to get the frosting light, smooth and fluffy.

Try to resist just eating all the frosting straight from the bowl. I promise, the final cake is worth it!

How to frost Banana Cake:

After letting the cakes cool in the pan for about 10 minutes, turn them out onto a wire rack. Don’t add the frosting until the cakes are completely cooled.

Place one layer of the banana cake on a cake plate. Spoon frosting over the top and use a flat spatula to smooth it over the whole top of the cake. Top with the second layer and repeat, spreading frosting over the sides of the cake.

Garnish with banana slices on top if desired, cut into pieces and serve!

Can you freeze banana cake?

YES! Banana cake is a great make ahead option because it freezes beautifully.

I prefer to freeze the cakes in individual layers before frosting. Wrap each layer in plastic wrap and then foil or a ziploc freezer bag. The cake keeps well frozen for about 3 months.

When ready to serve, let the cake thaw while you make the cinnamon butter cream, frost and layer as directed.

Got leftovers? Wrap individual slices in plastic wrap and slide in a freezer safe ziploc or container. Thaw each slice overnight.

More Tips & Tricks

  • How to make cake layers even: I use Wilton Bake Even Cake Strips to get perfectly even layers with no hassle. If you don’t have any, you can also slice off the puffed tops of your cake layers so they fit together evenly.
  • Use ripe bananas: To make this cake moist and sweet, I recommend using very ripe (even over ripe) bananas. They have higher sugar content and they mash up much more easily!
  • Mashing bananas: If you’re making the cake batter in a stand mixer, there’s no need to pre-mash the bananas first. Just add them to the bowl and your mixer will do the work for you! If you’re making this without a mixer, I recommend mashing the bananas in a separate bowl with a fork or potato masher to make sure no big chunks are left.
  • How to store: This cake stays moist and delicious for several days after baking! Store it covered in the fridge and enjoy cold or at room temperature.

Bananas and cinnamon together make for a heavenly combination. Make this Banana Cake layered with cinnamon buttercream frosting and everyone will want to fight over who gets the last piece!


For the Cake:

  • ½ cup butter, softened
  • 1 cup granulated sugar
  • 1 egg
  • 1 tsp vanilla extract
  • 3 medium bananas
  • 1 ¾ cup flour
  • 1 tsp baking powder
  • 1 tsp baking soda
  • ½ tsp salt

For the Frosting:

  • 1 cup butter
  • 3 ½ cup powdered sugar
  • 2 tsp cinnamon
  • 2-3 Tbsp milk


  1. Grease and flour two 9inch cake pans. I line the bottom with parchment paper as well. Set aside.
  2. For the cake, blend butter and sugar until creamy. Add egg and vanilla, beat until combined. Blend in bananas (you can mash them first, but I just toss them in my kitchenaid and it does the work for me). Add in flour, baking powder, baking soda and salt.
  3. Divide batter in half and pour into cake pans. Bake in a 350 degree oven for 25 minutes.
  4. Remove and cool. Let cake cool in pans 10 minutes, then flip onto a cooling rack to cool completely.
  5. For the frosting, beat butter until fluffy. Add in powdered sugar and cinnamon. Add milk.
  6. Beat for 5 minutes until desired consistency.
  7. To frost cake. Lay one layer of cake on cake plate. Spoon frosting over layer and smooth.
  8. Top with second layer of cake. Again spoon frosting on top and smooth. Using a spatula, spread frosting around the sides of the cake. Slice and serve!


    If you want to have your cakes flat, you could slice off the tops. However, I used Wilton Bake even Cake Strips. You wrap them around your pans and your cakes bake even! Go figure!
