Sour Cream Banana Bread Recipe

A quick search for “banana bread” around here and you’ll be inundated with dozens of variations on the classic quickbread. Peanut butter-filled? I’ve got you covered. Chocolate-swirled? Oh yes, indeed. Streusel-topped? You better believe it. And now I’m adding one more to the mix with The Ultimate Moist Banana Bread loaded with your choice of mix-ins.


Sour Cream Banana Bread Recipe

So what’s the real secret to moist banana bread? If you ask me, it comes down to a trifecta of ingredients:

  • Brown Sugar: Swapping out a portion of regular sugar for brown sugar adds a touch of molasses to the mix. And we know the addition of molasses to any baked good translates to moisture!
  • Vegetable Oil: Skip the butter in favor of oil and your banana bread will soar to new highs.
  • Sour Cream: Last, but definitely not least, sour cream is my go-to for sealing in moisture and adding a touch of tang to offset the sweetness of your banana-filled loaf.

Sour Cream Banana Bread Recipe

This recipe for The Ultimate Moist Banana Bread is all that and a bag of chips glass of cold milk. And it can be as loaded or as simple as your heart desires when it comes to mix-ins. I’ve opted for mini chocolate chips and chopped walnuts, but this recipe welcomes all options, from coconut flakes and fresh fruit to buttery streusel and crushed toffee.

Sour Cream Banana Bread Recipe
Prep Time 15 mins
Cook Time 1 hr
Total Time 1 hr 15 mins
Servings 8 servings


  • 2 cups all-purpose flour
  • 1/2 cup sugar
  • 1/4 cup packed light brown sugar
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 3 very ripe, darkly speckled bananas, mashed well (about 1 ½ cups)
  • 1/4 cup sour cream
  • 2 large eggs
  • 1/4 cup vegetable oil
  • 2 teaspoons vanilla extract
  • 2/3 cup chopped walnuts, pecans or chocolate chips


  • Preheat the oven to 350°F. Line a 9-inch loaf pan with parchment paper leaving an overhang on the two longer sides. Grease the parchment paper with cooking spray.
  • In a large bowl, whisk together the flour, sugar, brown sugar, baking soda and salt.
  • In a separate medium bowl, whisk together the mashed bananas, sour cream, eggs, vegetable oil and vanilla extract. Add the wet ingredients to the dry ingredients, mixing just until combined. Stir in any mix-ins, such as chopped nuts or chocolate chips, then scrape the batter into the prepared loaf pan.
  • Bake the bread for 50 to 60 minutes or until a toothpick inserted comes out clean. Remove the bread from the oven and allow it to cool in the pan for 10 minutes before using the parchment paper overhangs to lift the loaf out of the pan and onto a rack to cool completely.

    I really enjoyed this recipe! This is the first time I’ve made banana bread with oil instead of butter and it really does make a difference.

    I never have sour cream on hand so substituted apple sauce and it turned out just fine. Thanks for sharing such a great recipe!
