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.

To make the topping:

  • Mix together the topping ingredients into a small bowl. Mix well to combine. 
  • Pour batter into prepared pan. Drop crumb mixture over surface of batter. Cook in preheated oven for about 60 minutes or until a toothpick inserted into the middle comes out clean.

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.

    I made this sour cream banana nut bread and it was wonderful. I would put it into 2 pans instead of one. I baked my loaves at 310 instead of the 350. I would also double the brown sugar and granulated sugar if you want a little sweeter bread, otherwise it goes well with a cup of coffee in the morning, noon, or night.

  2. 5 stars
    Just made this bread today. Came out sooooo good! I had to bake it for 70 minutes, but was super easy and the topping came out delish! Thank you for sharing this recipe. I am so glad I tried it! Been looking for a yummy recipe for awhile. So glad I came across this one!❤️

  3. Why the F3%k do we have to read all of ur bs before one gets to ingredient amts? Wd don’t care about ur life?

    1. Oh, I’m sorry. Did the fact that I created the recipe, photographed it, and even created a step-by-step video so you knew exactly how to make it (all for free) bother you? If you took the time to actually read the post, I did not talk about my life – I only talked about the recipe with the intent to help out anyone who has never made banana bread before. Were you too lazy to click the “jump to recipe” button at the top to go DIRECTLY to the ingredient amounts?

      1. exactly!!! thanks! i exchanged 1/2 of the brown sugar with mollassas direct from the sugar mill. yummy

      2. I’m a new baker, so the intro helped me out a lot.

        I’m making this recipe for a second time. my mom loved it last time ❤️

      Did you not see the ‘Jump to Recipe’ at the TOP OF THE ARTICLE? There are no personal details about the author and, personally, I found the photos and info about ingredients very helpful.
      You must be an angry person with no friends. Nasty, false criticism, and swearing over a silly recipe doesn’t say much about you. Get a grip.
      Krissy, pay no attention to the trolls.

    1. soo good! 🙂
      i made quite a few mistakes with the batter and cook time, but it still turned out super moist. not only that, but it tasted incredible. thank you!

  4. 4 stars
    I’m sure this bread will be good….4 stars because the cook time is inaccurate. This recipe says bake for 60 mins BUT it is still in the oven after 90 mins and not done! So frustrating!!!! I have a very good oven & other recipes come out fine. Perhaps I should’ve used convection bake and adjust temp/time. Not sure why someone said you may need to reduce the cooking time.

  5. This recipe was spot on! I accidentally doubled up the butter, but it turned out great anyway. I also added dried cranberries and the zest of one orange. Very moist and firm. the crumble crust was a nice addition.
