Sour Cream Banana Nut Bread is super moist with a crunchy sweet topping.
Put those ripe bananas on your counter to good use and make a batch of this delicious quick bread. You can easily double or triple the recipe and then freeze the loaves!
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:
- First step is to cream together the butter and sugar, then mix in all of the remaining wet ingredients
- The dry ingredients are sifted together and then mixed into the batter
- Finally, the walnut pieces are stirred in
- Next you will prepare the streusel topping
- Pour the batter into a prepared loaf pan and cover with the streusel topping mixture
- 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.

Hi, I just pulled the bread out of oven. I followed your recipe exactly. It looks good. Just wondering why it is so flat? It’s not even 3 inches high. Thx, Linda
Any chance the baking soda you used is old? It’s a pretty dense recipe, so it won’t rise a ton, but it should rise.
Made it for my family today and they approved ๐ For the crumbles, I decided to layer it: batter, crumbles, batter and top with crumbles.
Oh Yum!
This turned out great. The only change I made was I used Greek Yogurt instead of sour cream.
This is probably the best banana bread I’ve ever made.
Thanks for the recipe Krissy!
I made this the other day. I looked for a recipe with a lower amount of sugar and found yours. (I didnโt add the topping as I wanted less sugar) It turned out excellent. It took 60 min exact to bake.
DELICIOUS!!! I will be making this again for sure ๐
