WHAT MAKES THIS BANANA BREAD SO GOOD?
Not only because it is delicious and easy to make, it is very nutritious with rolled oats and very little added oil! You won't believe how soft the texture is with just 4 tablespoons of oil in the recipe!
Also, it is THE MOST VERSATILE banana bread ever!
I've made this without peanut butter, without chocolate, or without the oats.
Then I've made it with blueberries... whatever I do, it just works!

This one right here features one of the best flavour combos of all time: Chocolate + Peanut Butter!
Add banana to that equation and it's everything we need to be happy 🙂
Peanut butter adds a bit of extra protein and rolled oats add a bit of extra fibre. When you take into account that there's just ¼ cup of oil (that's just 4 tablespoons or 60ml), this starts to seem like a perfectly appropriate breakfast item.

I love to add sour cream to loaf recipes to offset the sweetness and provide the acidity required to react thoroughly with baking soda.
Baking soda promotes even browning and a fluffy crumb to loaf recipes, but without acid to react with it will leave an unpleasant taste. A bit of sour cream fixes that - it's a little food science tip!

WHAT IS A SUBSTITUTE FOR SOUR CREAM?
I have also made this recipe with full fat yogurt in place of the sour cream and the results were excellent. Feel free to make that substitution if sour cream is not available where you live.

This banana bread is so soft, moist and perfectly sweet. It's hard to over-bake it too, so it's pretty much no-fail!
I hope you make it and let me know what you think!

Chocolate Peanut Butter Banana Bread
Ingredients
- 1 ⅓ cups 190g all-purpose flour

- ½ teaspoon baking soda

Made this twice now. First time was exactly how it is. Second tine I made as muffins and added cream cheese. Took the cream cheese mixture from your cheescake brownie recipe. Both times were a hit. Thank you!

This one has become a family favorite! I've baked it many times. As I can't find sour cream in Greece I indeed used Greek yogurt but I have to make a note, the Greek yogurt in other countries is as I understand less thick than the actual Greek yogurt, even if it's called Greek. So I used a whole one (200gr) or else th result wasn't fluffy enough

Thanks for your feedback Athena! I'm glad your family loves this recipe!
Sarah
Would there be any appropriate substitute for the sour cream? Trying to make a non dairy version.
christina.marsigliese
Hi Sarah, you can try plant-based sour cream or yogurt.
Yvonne
Can we use whole wheat flour?
christina.marsigliese
Hi Yvonne, you can but you will need to reduce the amount by about 25%.
Priyanka Kale
Any substitute for eggs??
christina.marsigliese
Hi! I've only tested this recipe as written with eggs.
