My banana bread recipe is one of the most popular recipes this time of year. One thing users often ask is how much spice to add if they want to make it with cinnamon which is how this recipe came to be. I didn’t have buttermilk the day I started developing the recipe so I decided to try it with sour cream. The result was delicious!

Why This Recipe Works

  • Using sour cream makes sure your banana bread comes out moist every time.
  • A combination of white and brown sugar adds extra flavor.
  • Vanilla bean paste adds a luxurious and deep vanilla taste that can’t be beat!

This fantastic banana bread recipe with sour cream is a variation on the classic recipe that I just love. I always have a few left over bananas at the end of the week and what better way to use them up?

How To Make Sour Cream Banana Bread

  1. Mash the bananas with the melted butter.
  2. Combine wet and dry ingredients.
  3. Bake for around 55 to 60 minutes.
  4. Decorate with sliced banana.
  5. Serve and enjoy!

Ingredient Notes

bananas, sour cream, brown sugar, and vanilla extract
  • Sour Cream: Use the full-fat sour cream as low fat liquifies when heated. It can be replaced like for like with Greek yogurt.
  • Bananas: The best bananas are the ones that are left in the fruit bowl that no one will eat because they look bad, the softer the banana the better the flavor.
  • Sugar: I use a combination of granulated sugar and brown sugar (the brown sugar gives a lovely caramel taste), but caster sugar also works well.
  • Vanilla: I like to use vanilla bean paste because it adds that extra special touch, however you can use vanilla extract or vanilla essence.
  • Brown Sugar: I use light brown sugar, but dark brown sugar can also be used, just be aware that dark brown sugar is not as sweet as light brown sugar.

Step By Step Instructions

Mash the bananas with the melted butter using a potato masher or fork.

Erren’s Top Tips

  • Be sure to follow the steps of the recipe. Mixing the dry and wet ingredients well separately before combining them helps to avoid over mixing, this will create a dense, tough loaf.
  • Measure your flour correctly by using a measuring cup meant for dry measurements, and level off the top of the cup once the flour is scooped. This will ensure you’re not adding extra, which will result in a dry loaf.
  • To avoid the sour cream banana bread sticking to the pan, use a good quality, non-stick pan that’s greased well with baking spray or shortening (butter can cause sticking). When in doubt, line the pan with greased parchment paper.
  • Love Nuts? Use a combination of your favorite varieties!

Storing & Freezing Instructions

  • In the Fridge: Store this cake at room temperature in an airtight container for up to 3 days
  • In the Freezer: Wrap the cake in plastic wrap and place in a freezer safe container, freeze for up to three months.

Other Great Bakes

  • Ultimate Orange Cake
  • Citrus Olive Oil Bundt Cake
  • Berry Whipped Cream Cake
  • Chocolate Mayonnaise Cake

    measurement/weight of bananas? They are all different sizes! I’m guessing 1 1/2 c?

      When it comes to bananas, the size and ripeness can indeed vary, you are correct!

      As a general guideline:
      1 medium banana typically yields about 1/2 cup of mashed banana.
      So, 3 medium bananas would give you about 1 1/2 cups of mashed banana. Great job with that guess!

      If your bananas are on the smaller or larger side, you can adjust the amount to reach approximately 1 1/2 cups.
