Banana Cake with Buttercream Frosting

This easy Homemade Banana Cake with buttercream 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.

  • sugar
  • sour cream
  • eggs
  • salted butter
  • super ripe bananas (a lot of brown spots)
  • vanilla extract
  • all-purpose flour

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.

    My mom always made banana cake but frosted it with peanut butter frosting – you will have to try that – it was delicious! 🙂 LOVE your site and recipes! Thanks so much for sharing!

  4. Wow..I love this cake! My family raved about it. I made it again today and somehow forgot to add in the sugar haha. It was a bit bland but the frosting made up for it! (I did a whipped cream cheese frosting this time). This cake is a total winner in our home 🙂

  5. Hello Norway!! I don't see why you couldn't make these into cupcakes. You'll have to adjust the baking times slightly though 🙂

  6. I know exactly what you are talking about ….. And this recipe looks delicious. Cannot wait to try this one.
