Rich, chocolaty, and loaded with sweet banana flavor, this chocolate banana bread turns those spotted bananas on your counter into an irresistible snack that’s wonderful any time of day.

If you love banana bread but never say no to chocolate, this chocolate banana bread combines the best of both. Cocoa powder and plenty of chocolate chips create rich chocolate flavor, while sour cream keeps every slice exceptionally moist and tender. Ripe bananas add natural sweetness and plenty of banana flavor. It comes together like a classic quick bread but tastes almost like chocolate cake—perfect for breakfast, an afternoon snack, or dessert.
Love chocolate quick breads? Be sure to try my chocolate zucchini bread too—it’s just as rich, moist, and chocolatey.
“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: Provides the structure for the loaf. Measure it by spooning the flour into your measuring cup and leveling it off with a knife rather than scooping directly from the bag, which can pack in too much flour and lead to a dry loaf.
- Natural unsweetened cocoa powder: Gives the bread its rich chocolate flavor. Be sure to use natural cocoa powder rather than Dutch-process cocoa, as its acidity reacts with the baking soda to help the loaf rise properly.
- Baking soda: The leavening that gives the bread its lift and tender crumb. It reacts with the acidity in the natural cocoa powder and sour cream. (Baking powder is never a suitable substitute; for more on the difference between the two, see my guide to baking soda vs. baking powder.)
- Salt: Enhances both the chocolate and banana flavors while balancing the sweetness. All sweet treats need a touch of salt!
- Unsalted butter: Adds richness and buttery flavor. Make sure it’s softened to room temperature so it creams easily with the sugar.
- Sugar: Sweetens the bread while also contributing to its soft, tender texture.
- Large eggs: Bind the batter together and provide structure.
- Mashed bananas: The riper the bananas, the better. Look for peels that are heavily speckled or mostly brown, as overripe bananas are sweeter, softer, and mash more easily into the batter. Frozen bananas work well too (see my post how to freeze bananas for details on freezing and thawing). Pro tip: To quickly ripen bananas, store them in a loosely sealed brown paper bag.
- Sour cream: One of the keys to this recipe. It makes the loaf exceptionally moist and tender while its acidity works with the baking soda to create a lighter texture. Full-fat plain Greek yogurt can be substituted in a pinch.
- Vanilla extract: Rounds out the flavors and enhances both the chocolate and banana.
- Semi-sweet chocolate chips: Create little pockets of melted chocolate throughout the loaf for a double dose of chocolate. Feel free to stir in a handful of chopped walnuts or pecans for crunch, or substitute some of the chocolate chips with white chocolate or peanut butter chips for a fun variation.

STEP-BY-STEP Instructions
Step 1: Mix the dry ingredients. Whisk together the flour, cocoa powder, baking soda, and salt. Set aside.

Step 2: Cream the butter and sugar. In another bowl, cream the butter and sugar until light and fluffy. This step helps create a tender crumb, so don’t rush it.
Pro tip: Make sure your butter is fully softened before you start — it should give easily when you press it but still hold its shape. If it’s too cold, it won’t cream properly; if it’s too warm and greasy, you won’t get that light, fluffy texture.

Step 3: Add the eggs. Add the eggs one at a time, beating well after each addition until fully incorporated before adding the next.

Step 4: Add the dry ingredients. Add the dry ingredients to the butter mixture and beat gently until just combined.

Step 5: Mix in the bananas, sour cream, and vanilla. Mix in the mashed bananas, sour cream, and vanilla until just evenly incorporated. It’s important to avoid overmixing once the flour is added, as it develops the gluten in the flour, which can make quick breads tough instead of tender.

Step 6: Fold in the chocolate chips. Add the chocolate chips and fold with a rubber spatula until evenly incorporated. The batter will be quite thick—that’s exactly what you want. Pour the batter into a greased loaf pan and spread evenly with a spatula. Don’t worry if it isn’t perfectly level, as it will even out as it bakes.

Step 7: Bake and cool. Bake for about 70 minutes, or until done. A toothpick inserted into the center should come out with a few moist crumbs attached but no wet batter. Because chocolate batters are dark, it’s harder to judge doneness by color alone. Let the bread rest in the pan briefly, then turn it out onto a rack to finish cooling. The bread is best freshly baked, but keeps at room temperature for up to 3 days or can be frozen for longer storage.
Freezing tip: If you’d like to enjoy the bread as an occasional snack when a craving strikes, before freezing, slice the bread and wrap the slices individually— that way you can pull out exactly what you need rather than thawing the whole loaf.

Chocolate Banana Bread
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
- ½ cup (1 stick) unsalted butter, at room temperature
- 1 cup sugar
- 2 large eggs
- 1 cup mashed very ripe bananas, from 2 to 3 brown bananas
- ½ cup sour cream
- 1 teaspoon vanilla
- ½ cup semi-sweet chocolate chips
Instructions
- Preheat the oven to 350°F (175°C) and set a rack in the middle position. Grease a 9 x 5-in (23 x 13-cm) 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.
Notes
- 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/Freezing 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.

The smell of this Chocolate Banana Bread baking evokes a Pavlovian response from family members, who shuffle into the kitchen to stare at the timer on the oven. The only thing I do differently is use Ghirardelli tiny chocolate chips because they seem to get distributed throughout the loaf, rather than settling on the bottom.
Made this bread last week, it is delicious except for the fact that the Chocolate overpowers the Banana. I could taste some banana but it was almost like a flavoring. The the cake is very moist and tastes good especially if you like chocolate.
This is now a family favorite!! It is very moist and keeps well….I will definitely be making this again…Thanks Jen!!
This is a good recipe for Chocolate Banana Bread. I didn’t change a thing in the recipe, amount of sugar is just right. I baked it in two 8 x 4 pans at 325 degrees for 35 minutes. It turned out perfect, moist and chocolatey. I love the chocolate chips in the bread
Just made this and it is delicious! I doubled the recipe and used white whole wheat flour, plain yogurt for the sour cream, and only 1 1/4C sugar. Came out great! I also used double dutch dark cocoa powder from King Arthur Flour and it tasted just fine.
This is delicious! I did not have sour cream, so I substituted with cream cheese. I did not have chocolate chips either (because my kids used an entire bag to make chocolate balloon bowls last night) so I substituted with white chocolate chips. Personally, I think both of these additions to your wonderful recipe kept it just as delectable. I made two loaves; one is in the freezer. Thanks so much. xo Natalia
Also, I made my banana bread with 1 cup of sugar today but do you think it would turn out the same next time if I used any of these sugar substitutions: To replace 1 cup of white sugar you can substitute it for 3/4 cup honey, or 3/4 cups maple syrup or 2/3 cup agave or 1 teaspoon stevia.
Hi Misty, I wouldn’t recommend using honey or maple syrup in place of the sugar. And regarding other alternatives like agave or stevia, I don’t have enough experience with either of those to say confidently how they would impact the results. If you try either, I’d love to hear how it turns out!
Hi, why can’t honey or maple syrup be subbed here? Is it because of the butter? In which case, can we make your Healthy Banana bread (using coconut or olive oil and honey or syrup), then just add cocoa powder? Thank you for all your hard work!
Hi Elle, while a small portion of honey (or maple syrup) can be used in place of sugar in baked goods, honey browns much faster than sugar and can lead to burning. And for a bread like this one that is already dark in color because of the chocolate, it would be hard to tell if it is getting overly browned. Hope that clarifies! 🙂
It clarifies that you’re awesome. Thank you!
I just made this banana bread and it is truly delicious! (You are right…it tastes like moist chocolate cake!). What type of loaf pan do you use? (I am trying to read the wording in your photos but I can’t make it out). I have a stainless steel loaf pan that I buttered then sprayed with coconut oil, yet my banana bread stuck to the bottom of the pan which is not a problem for our family, but I would like to get a non-toxic loaf pan that I know will work for future loaves of bread. Thank you!
Hi Misty, glad to hear you enjoyed the banana bread! The loaf pan you see in the recipe photos is a KitchenAid one, but not sure they make it anymore. I recently bought a new loaf pan that I really like; it’s by USA Pan. Hope that helps!
Chocolate Banana Bread – The bread is wonderful and moist. When I make it I add chopped roasted pecans and omit the chocolate chips. I have made this recipe several times.
Excellent. I’m a retired chef, living at 7000′ altitude and rarely does any baking recipe NOT need adjustments. Took a chance, followed this as is. Perfect, done in 1 hour. Used extra dark chocolate chips, all I had on hand, guitars. This banana bread tastes great, as someone said, like a chocolate cake! Thanks!
