Ingredients
½ cup canola or vegetable oil, plus more for the pan
1 ½ cups/360 grams mashed bananas (from 3 to 4 very ripe medium bananas)
½ cup/120 grams sweetened creamy or chunky peanut butter (not natural)
¼ cup/60 grams sour cream
1 cup/201 grams sugar
2 large eggs
2 teaspoons pure vanilla extract
1 ½ cups/192 grams all-purpose flour
¾ teaspoon baking powder
½ teaspoon baking soda
¾ teaspoon kosher salt (such as Diamond Crystal)
1 cup/170 grams chopped semisweet chocolate or chocolate chips
Preparation
- Step 1
Heat the oven to 350 degrees. Grease a 4 ½-inch-by-8 ½-inch loaf pan, then line with parchment, leaving a 2-inch overhang on two sides.
- Step 2
In a large bowl, whisk together the oil, bananas, peanut butter and sour cream until smooth. Whisk in the sugar, eggs and vanilla until well combined.
- Step 3
In a medium bowl, whisk the flour, baking powder, baking soda and salt to combine. Add the flour mixture to the banana mixture and stir to combine. Use a flexible spatula to fold in the chocolate by gently scooping the batter from the bottom and folding it over the top. Rotate the bowl and repeat until just combined.
- Step 4
Pour the batter into the prepared loaf pan and spread into an even layer. Bake until a skewer inserted into the center comes out with a few moist crumbs attached, 55 to 65 minutes. (If the top of the loaf is becoming too dark before it’s baked through, loosely cover with foil.)
- Step 5
Transfer the loaf from the oven to a cooling rack and run a thin knife around the two short edges of the banana bread to separate it from the pan. Let cool in the pan for 10 minutes before using the parchment to transfer the bread to a rack to cool completely. Store the bread in an airtight container at room temperature for up to 3 days, or slice and freeze for up to 1 month. To reheat, wrap in foil and bake at 325 degrees for 10 minutes. (You could also brown the slices with butter in a skillet over medium-high and serve sprinkled with flaky salt.)

I used natural peanut butter and Greek yogurt because it's what I had on hand. I cut the oil down to 1/3 cup to account for the higher fat content of the PB. And cut the sugar down by ~3Tbsp because I like less sweet. Delicious recipe! Wonderfully moist crumb with a slight savory note to the taste. I'll definitely make again. Maybe switch to an 8"x8" pan to speed up bake time and lean into the dessert cake vibe.
I made this today as part of some post-election stress baking. I made it mostly as directed with one unintentional omission. In my sleep-deprived state I completely forgot to add any sugar. But it was actually ok! I did add a heaping cup of chocolate chips so maybe that plus the sweetness of the peanut butter made up for the lack of added sugar. I also usually cut down the amount of sugar in banana bread recipes since I don’t have a big sweet tooth. I only noticed the omission because the outside of the bread had a different texture than I’m used to. I’ll definitely make this again, and next time I will probably add a half cup of sugar and see how that compares.
What happens if you use all natural PB instead of conventional?
This turned out so so good! I veganized this with Bob's Red Mill Egg Replacer and the scraps of my leftover vegan sour cream and vegan Forager Greek yogurt. It took about 75 minutes to bake. The top was a little dark, I tented it with foil a little too late. It all turned out though. This bread is so moist, soft, and delicious! Will definitely bake again! I'm just so glad it turned out so well with the vegan mods.
substitutions i made cuz i didnt have the ingredients and turned out amazing - 70 gr sugar - 30 gr refined sugar i had kept in a vanilla jar - sme weight fagr yogurt instrad of sour cream - 3 extraaaa ripe bananas
I made this exactly as written and we like a lot. A nice texture with a subtle peanut butter flavor. I made it in an XL cast iron loaf pan (appx 10x5) and it worked out perfectly. It made a beautiful loaf.
