Rich, chocolaty, and loaded with banana flavor, this chocolate banana bread is as delicious as it is easy to whip up! Enjoy it as a breakfast treat, afternoon snack, or dessert—it’s perfect any time of day.
I usually think of banana bread as a breakfast treat (or, let’s be honest, something you grab a little slice of every time you pass through the kitchen). But this chocolate banana bread is so rich and decadent, you could easily top it with a scoop of vanilla ice cream and call it dessert. With chocolate chips and cocoa powder for a double dose of chocolate and sour cream to keep it irresistibly moist, this quick bread is always a family favorite.
“Exquisite, fabulous, hands down the most beautiful, moist, decadent, delicious, cake-like, chocolaty, awesome banana bread I’ve ever had.”
What You’ll Need To Make Chocolate Banana Bread

- All-Purpose Flour: The base of your chocolate banana bread. Measure it by spooning it into the measuring cup and leveling it off to ensure accuracy.
- Natural Unsweetened Cocoa Powder: Adds a rich chocolate flavor. It’s important not to substitute this with Dutch-process cocoa powder due to differences in acidity.
- Baking Soda: Acts as a leavening agent, helping the banana bread rise.
- Unsalted Butter: Provides moisture and richness. Using it at room temperature ensures it creams well with sugar.
- Sugar: Adds sweetness and contributes to the bread’s tender texture.
- Large Eggs: Bind the ingredients together and add structure.
- Mashed Bananas: The star ingredient for moisture and flavor. Use very ripe, brown bananas for the best taste. To quickly ripen bananas, store them in a loosely sealed brown paper bag. (Overripe bananas can be frozen—simply peel and store them in a resealable bag in the freezer, ideally 2 to 3 bananas per bag, as this is the common amount used in recipes.)
- Sour Cream: Adds richness and ensures the banana bread is moist.
- Vanilla Extract: Enhances the overall flavor of the bread.
- Semi-Sweet Chocolate Chips: Add gooey, chocolatey pockets to the bread. If you’d like, you can also add a handful of chopped nuts, like walnuts or pecans for extra texture and flavor. You can also substitute some of the chocolate chips with white chocolate or peanut butter chips for a different twist.

Step-by Step Instructions
To begin, combine the flour, cocoa powder, baking soda, and salt in a large bowl. Whisk well and set aside.

In another bowl, cream the butter and sugar until light and fluffy.

Add the eggs one at a time, making sure to mix well after each addition.

Next, add the dry ingredients to the butter and egg mixture.

Beat gently until just combined, then mix in the mashed bananas, sour cream and vanilla.

Add the chocolate chips and fold with a rubber spatula until evenly incorporated. Be sure not to overmix the batter.

Pour the chocolate banana bread batter into a greased loaf pan and spread evenly.

Bake until done, about 1 hour and 10 minutes.

Let the chocolate banana bread rest in the pan for about 10 minutes, then turn out onto a rack to cool completely. The bread is best enjoyed fresh, but it can be stored at room temperature for up to 3 days or frozen for longer storage.

Deeply chocolaty and wonderfully tender, this chocolate banana bread is the perfect way to use up your ripe bananas—comfort food at its best!
Ingredients
- 1¼ cups all-purpose flour, spooned into measuring cup and leveled-off
- ¼ cup natural unsweetened cocoa powder, such as Hershey's (see note)
- 1 teaspoon baking soda
- 1 teaspoon salt
- 1 stick (½ cup) unsalted butter, at room temperature
- 1 cup sugar
- 2 large eggs
- 1 cup mashed very ripe bananas, from 2-3 brown bananas
- ½ cup sour cream
- 1 teaspoon vanilla
- ½ cup semi-sweet chocolate chips
Instructions
- Preheat the oven to 350° F. Grease a 9 x 5 x 3-inch loaf pan with non-stick cooking spray.
- In a medium bowl, combine the flour, cocoa powder, baking soda and salt. Whisk until there are no more lumps in the cocoa powder and the mixture is well combined. Set aside.
- In a large bowl or electric mixer fitted with the paddle attachment or beaters, beat the butter and sugar until light and fluffy, 2 to 3 minutes. Add the eggs one at a time, incorporating well after each addition. Add the dry ingredients and beat gently until just combined. Add the bananas, sour cream and vanilla and mix on low speed to combine. Fold in the chocolate chips. Do not overmix.
- Pour the batter into the prepared loaf pan and spread evenly with a spatula. Bake until a toothpick inserted into the center comes out with a few moist crumbs attached, about 1 hour and 10 minutes. Let the loaf rest in the pan for about 10 minutes, run a blunt knife around the edges to loosen, then turn it out onto a rack to cool completely.
- Note: There are two types of unsweetened cocoa powder: natural (such as Hershey's) and Dutch-processed. Dutch-processed will not work in this recipe.
- Make-Ahead/Freezer-Friendly Instructions: The bread is best enjoyed fresh, but it can be wrapped in aluminum foil and stored at room temperature for up to 3 days. If you'd like to keep it longer, the bread can be frozen for up to 3 months. After it is completely cooled, wrap it securely in aluminum foil, freezer wrap, or place in a freezer bag. Thaw overnight in the refrigerator before serving.

This is my second time making this recipe and it has come out amazing both times. The first time i used big chocolate chips and they all fell to the bottom so make sure to use the mini ones. The texture of this banana bread is amazing. Thanks for the great recipe.
Is this recipe suitable for making muffins?
Yes I think it’d work. Enjoy!
I made the Chocolate Banana Bread yesterday. My children all like it very much. It is such a good recipe.
Worked very well! Mine turned out so fluffy that it overflowed quite a bit – I’d recommend a cookie sheet be placed on the rack below to catch drippings. I didn’t have sour cream to subbed full fat European style yogurt (not Greek) with a tbsp of lemon juice – and it turned out fine taste and texture. I accidentally put too much cocoa powder. Despite all of this the recipe was very forgiving.
Excellent! I used greek yogurt instead of the sour cream and it worked out perfectly. This is indeed another great recipe. Thank you Jen!
Made exactly per recipe. It’s much more a fluffy cake texture than a typically moist, dense banana bread. Tasted great … just not banana bread.
Hi Jenn
I made this last night and want to make it again. I overbaked it a little (my fault, not the recipe’s) so it came out drier than I would like but I have a few questions …if I mix it a little less, can that help with making it more moist? Also I used the Whole Foods natural canola spray and it was too oily and drippy. Is it OK to prepare the pan using the traditional butter/flour/lime with parchment paper method? I have heard that other cooking sprays have chemical propellants, which I sought to avoid. One last question – would tossing the chips in flour avoid them from sinking? Thanks for all your amazing recipes.
Hi S, sorry to hear this came out a bit dry. The dryness is likely because it was overbaked as opposed to overmixing. Also, dryness is often caused by measuring the flour incorrectly. Did you use the spoon and level method to measure the flour? Even a few extra ounces can make a big difference. This article/video explains it nicely. And it’s fine for you to prepare the pan using the method you described. Last, if you found that the chocolate chips sunk to the bottom, it would be fine to toss them with a tiny bit of flour. (And so glad you like the recipes!)
Delicious!
I made this Banana Bread few days ago and I used Rodelle organic baking cocoa (dutch processed) because I didn’t have any other type. Came out perfect and it was delicious !!!
It was gone in one day. I will absolutely make this again 🙂
Thank you Jennifer.
I made these today (followed the exact recipe…just too many for 12, so made 14 muffins)…and they were fantastic!! Thank you!
How long did you bake the muffins for Tammy?
