Why this recipe works:

If you love a good baking recipe, you’re going to be thrilled with this banana walnut bread recipe.

  • It’s super moist because the recipe uses sour cream and a lot of ripe mashed banana.
  • There’s a sweet and crunchy topping
  • There are tons of walnuts and loads of smashed ripe banana in this recipe which means tons of flavor and great texture
  • This banana bread freezes exceptionally well, so plan on making a lot if you have extra bananas

Ingredients used:

One of the things I love most about banana bread is that I almost always have everything I need in my pantry and refrigerator.

  • Butter – make sure it’s nice and soft
  • Granulated sugar and golden brown sugar – I find using both instead of one or the other yields the best results
  • Eggs – I always have them at room temperature when baking
  • Large ripe bananas – my ideal banana bread banana is yellow with lots of dark brown spots
  • Vanilla – make sure you use pure vanilla extract and not imitation
  • Sour cream – not lowfat
  • All-purpose flour – unbleached recommended
  • Baking soda – make sure it’s reasonably fresh when you use it for cooking
  • Cinnamon – I almost always replace with Pumpkin Pie spice when I bake
  • Salt – every sweet recipe needs salt
  • Walnuts – when I bake, I always use raw (not dry roasted) nuts

How to make it:

  1. First step is to cream together the butter and sugar, then mix in all of the remaining wet ingredients
  2. The dry ingredients are sifted together and then mixed into the batter
  3. Finally, the walnut pieces are stirred in
  4. Next you will prepare the streusel topping
  5. Pour the batter into a prepared loaf pan and cover with the streusel topping mixture
  6. Bake the loaf for about an hour

Recipe tips:

  • Bananas – The ideal banana is mostly yellow and just starting to brown. I will actually squeeze them while they’re still in the peel because it makes it easier to mash up the ripe banana once it’s in the bowl.
  • Nuts – This recipe calls for walnuts but you can easily substitute with a different nut if you prefer. I’ve used pecans as well as macadamia nuts. Raw nuts are recommended over roasted.
  • Baking tips –
    • You can either grease the loaf pan or use parchment paper. I prefer parchment so that as soon as it’s done cooking, you can lift the loaf out of the pan and pull the loaf out of the paper to cool. This will prevent it from getting soggy.
    • Be sure to insert a cake tester into the center of the loaf to ensure there is no wet batter before removing from the oven. If the top appears to be too brown, you can set the loaf lower in the oven to allow it to finish cooking without getting too browned on top.
  • Freezing tips – 
    • The loaf or loaves (if doubling recipe) must be fully cooled before freezing.
    • Wrap in foil or plastic wrap to eliminate air and prevent freezer burn. I actually now wrap the loaves in freezer paper and then in foil.
    • This banana bread should last 6-12 months in the freezer as long as you’re able to prevent freezer burn. To enjoy, allow to fully thaw before slicing.

Notes

Makes 1 standard sized loaf
You may use two mini loaf pans in place of a single standard size loaf pan if you wish. Cooking time will be reduced, so remove from oven when center is cooked.
If you have a lot of ripe bananas, you may want to double or triple this recipe.
This banana bread freezes well. Just slice, wrap tightly with plastic wrap, and freeze until ready to eat. For longer storage you may also want to use freezer paper to keep it from getting freezer burn.

  1. I had serious hope for this recipe because my boyfriend swears up and down this is the one he used when he surprised me longer ago by making me some (because a good, warm slice of banana bread is my favorite!). I ended dumping this before even adding my bananas. After reading the comments of others who had issues I’m wondering if it’s because there isn’t enough sugar? Looking at other comparable recipes, those that start with 1/2 cup softened butter you end up adding 1 cup sugar…this one only adds half that (1/4 granulated + 1/4 brown sugar). I dumped mine because with the butter, vanilla, sugar, eggs and sour cream it was waaaay too runny. It didn’t look right and didn’t want to waste the bananas.

    1. Hi Tiffany, I’ve made this recipe several times and I can guarantee that it turns out perfectly. I have a recipe video as well… just haven’t finished editing it. I’m sorry you threw it away before even trying to bake it! I use less sugar because I don’t think it needs that much, esp if your ripe bananas are extra sweet. Krissy

  2. Stepping away from my traditional recipe, I was excited to try yours….the idea of using sour cream and have a crumble topping made it seem so unique. Following your directions to a tee, after 1 hour of baking, the cake is not set…..it’s rather ‘wet’ and I am at a loss to know what to do. The topping is well done and browned, but the inside is not.

    Not sure why but so disappointed. Will let it sit on the counter and hope for the best – then I will slice and freeze it until an idea comes to me.

    1. Sorry this happened! Sounds like your oven cooks hotter on top than mine does. I’m guessing this recipe would work better for you if you cooked the bread on the lower rack of your oven. Also, did you use a metal bread pan or something different like glass or ceramic? I ask because the glass or ceramic can slow the cooking time. -Krissy

        1. 😂 wait you skipped flour. That’s ok. I once forgot eggs in my cake. Don’t feel bad. Just try again. Try to follow in order. It’s extremely hard for me because I have ADHD. But luckily I know basically this recipe and I love it. The only thing I do differently is add a quarter cup of OJ. It gives it its own unique taste without being citrusy. Thanks Krissy for taking the time to post your recipe and I did try cinnamon and made topping for first time. In oven now we shall see. 💜

  3. Excited to try this but I followed the recipe to a T And it’s been baking for an hour and a half and still isn’t done. What gives?

    1. Did it turn out for you? Sometimes baking times can vary drastically with things like quick breads depending on your altitude and humidity. I hope it worked!

      1. Can this recipe be done without bananas? I made it last week, it was delicious but my family prefers without bana6.

    Seriously, honestly, absolutely, and overwhelmingly THE best recipe I’ve ever discovered on the internet. It’s really that good.. I now actually like banana bread vs just tolerate it. This is great! Thanks..

  5. 5 stars
    GR8 recipe. Days flew by n I was concerned the bananas were way past ripe n recipe would have that spoiled banana taste. Nope bread turned out to be delicious, moist n perfect for breakfast midday n evening desert . Had to try them all so I could be sure. Made with extra nuts because we love them, an old corning ware dish that was readily available, a toaster oven, long story n skipped the topping just because. Will definitely make again only this time will double the recipe, may even use loaf pans n inclued topping. It was that good.

    1. I made this and I shared with family and my neighbor. Everyone raved about it! I definitely need to make more; at least a double recipe!!!
