Why You’ll Love This Chocolate Tahini Banana Bread
This isn’t just another banana bread recipe; it’s a carefully crafted loaf designed to deliver maximum flavor and texture. Here’s what makes this chocolate tahini banana bread a must-try:
- The Creaming Method for Superior Texture: This recipe utilizes the classic creaming method, where butter and sugar are vigorously whipped together until they become light, fluffy, and pale in color. This process incorporates air into the mixture, resulting in an incredibly tender and airy crumb. The dry ingredients and sour cream are then added in three alternating additions, ensuring a well-emulsified batter and preventing overmixing, which can lead to a tough loaf. The meticulous attention to this foundational step is key to the banana bread’s signature softness.
- Sour Cream for Unbeatable Moisture: A generous amount of full-fat sour cream is a secret weapon in this recipe, imparting unparalleled moisture and a subtle tang that perfectly complements the sweetness of the bananas and chocolate. It contributes to a richly flavored, exceptionally tender crumb that stays fresh longer. If sour cream isn’t readily available, or you prefer an alternative, full-fat Greek yogurt can be used as a direct substitute, offering a similar moisture boost and a slight tang.
- Tahini: The Unexpected Star Ingredient: Tahini, a paste made from ground sesame seeds, is typically found in savory Middle Eastern dishes like hummus. However, its rich, nutty, and slightly bitter flavor profile is surprisingly versatile and truly shines in sweet applications, much like in traditional halva. In this banana bread, tahini adds a sophisticated depth and an earthy counterpoint to the sweet bananas and intense chocolate, creating a complex and incredibly addictive flavor combination that will surprise and delight your palate.
- Beautiful Swirl and Elegant Toppings: Beyond its incredible taste, this banana bread is a visual masterpiece. The dramatic chocolate swirl achieved by layering the plain and tahini-infused batters makes every slice look gourmet. Before baking, a sprinkle of both white and black sesame seeds adds a delicate crunch and a beautiful aesthetic, hinting at the tahini within. For an even more indulgent finish, consider topping the cooled loaf with a rich chocolate ganache, transforming it into an elegant dessert fit for any special occasion.
- Quick Preparation, Lasting Enjoyment: Despite its gourmet appearance and complex flavors, this banana bread requires only 15 minutes of active preparation time. The majority of the work is done by your mixer, allowing you to enjoy the baking process without feeling rushed. It’s a perfect recipe for those who want to create something truly special without spending hours in the kitchen.
Essential Ingredients for Your Chocolate Tahini Banana Bread
Crafting the perfect loaf begins with selecting the right ingredients. Each component plays a vital role in achieving the moist, flavorful, and beautifully swirled banana bread you’re aiming for. Pay attention to quality and temperature for the best results.

The printable recipe card with the full list of ingredients and detailed instructions can be found at the bottom of this post
- Bananas: The star of the show! For the best flavor and ease of mashing, ensure your bananas are very ripe. Look for several dark spots or even an almost entirely black peel. Ripe bananas are not only easier to mash into a smooth consistency, but their sugar content is also significantly higher, contributing to a naturally sweeter and more aromatic banana bread. If your bananas aren’t quite ripe enough, see our FAQ section for tips on speeding up the ripening process.
- Sour Cream: This ingredient is a game-changer for moisture. Sour cream’s acidity helps break down gluten in the flour, resulting in an incredibly tender and moist crumb. It also adds a subtle tang that balances the sweetness. If you don’t have sour cream, full-fat plain Greek yogurt or buttermilk can be excellent substitutes. Ensure it’s at room temperature for optimal mixing with the other ingredients.
- Butter: I always recommend using European-style unsalted butter, such as Kerrygold, in my recipes. European butter boasts a higher butterfat content compared to its American counterparts, which translates to a richer, creamier flavor and a more luxurious texture in your baked goods. Always use unsalted butter to control the overall salt content in your recipe. Make sure it’s at proper room temperature – soft enough to make an indentation with your finger but not melted.
- Granulated Sugar & Light Brown Sugar: The combination of these two sugars provides the perfect balance of sweetness and moisture. Granulated sugar offers sweetness and helps with browning, while light brown sugar, with its molasses content, adds a deeper, caramelized flavor and extra moisture, contributing to the banana bread’s chewy texture.
- Eggs: Eggs act as a binder, provide structure, and add richness to the banana bread. For best results, use a large egg and ensure it’s at room temperature. A room-temperature egg emulsifies more easily with the butter and sugar, creating a smoother, more uniform batter.
- Vanilla Extract: A touch of pure vanilla extract enhances all the other flavors in the bread, adding a warm, aromatic depth that is essential in most baked goods.
- All-Purpose Flour: Use unbleached all-purpose flour. While not glamorous, it’s the structural backbone of your bread. Measuring flour by weight (grams) is highly recommended for accuracy, as scooping directly from a bag can lead to too much flour, resulting in a dense, dry loaf.
- Baking Soda: This leavening agent reacts with the acidic sour cream and bananas to create carbon dioxide bubbles, giving the banana bread its lift and tender texture. Ensure your baking soda is fresh for optimal results.
- Kosher Salt: Salt is crucial for balancing flavors and enhancing sweetness. Kosher salt has larger flakes and a cleaner taste than table salt. If using fine table salt, halve the amount specified in the recipe.
- Cocoa Powder: Unsweetened cocoa powder is essential for creating the rich chocolate swirl. Use a good quality natural unsweetened cocoa powder for the best chocolate flavor and color. It should be sifted to prevent lumps in the batter.
- Tahini: This Middle Eastern sesame paste is the unique ingredient that makes this recipe special. It imparts a delightful nutty, slightly savory, and earthy flavor that pairs exquisitely with both banana and chocolate. Look for a good quality tahini that is smooth and pourable, ideally made from hulled, roasted sesame seeds. You can typically find it in the international foods aisle of most grocery stores. Stir it well before measuring, as the oil often separates.
- Sesame Seeds (White & Black): Used for topping, these provide a lovely visual contrast and a subtle nutty crunch, complementing the tahini flavor within the bread. They’re optional but highly recommended for that gourmet finish.
Step-by-Step Guide to Baking Your Swirled Banana Bread
Follow these detailed steps to create a show-stopping chocolate tahini banana bread that’s moist, flavorful, and beautifully swirled.

Step 1: Prepare Your Bananas. Begin by preheating your oven to 350°F (175°C). Next, grease and line an 8.5×4.5 inch loaf pan with parchment paper, leaving an overhang on the longer sides to easily lift the baked bread out later. In a medium bowl, mash your ripe bananas thoroughly with a fork or a potato masher until mostly smooth with only small, desirable lumps. Set the mashed bananas aside. This ensures they are ready to be incorporated into the batter at the right moment.
Step 2: Cream Butter and Sugars. In the bowl of a stand mixer fitted with the paddle attachment, or using a large bowl and a hand mixer, beat your room-temperature unsalted butter on medium speed until it’s creamy and smooth, about 1-2 minutes. Then, add both the granulated sugar and light brown sugar to the butter. Continue beating on medium-high speed for 2-3 minutes until the mixture is light, pale, and fluffy. This creaming process is crucial as it incorporates air, which contributes to the bread’s tender texture.

Step 3: Combine Dry Ingredients. In a separate medium bowl, whisk together your all-purpose flour, baking soda, and kosher salt. Whisking ensures that the leavening agent and salt are evenly distributed throughout the flour, leading to a consistent rise and flavor in your finished banana bread. Set this mixture aside.
Step 4: Incorporate Wet Ingredients. With the mixer still on low speed, add the vanilla extract, room-temperature egg, and tahini to your creamed butter and sugar mixture. Beat until all these wet ingredients are thoroughly combined and the mixture is smooth. Scrape down the sides of the bowl as needed to ensure everything is incorporated. Next, reduce the mixer speed to low and add your mashed bananas. Mix just until combined; it’s perfectly normal for the mixture to appear slightly lumpy due to the mashed bananas. Avoid overmixing at this stage.

Step 5: Alternate Dry and Wet Additions. Gradually add your dry ingredients in three additions, alternating with the room-temperature sour cream. Start by adding one-third of the dry ingredients, mixing on low speed just until almost combined. Then, add half of the sour cream, mixing gently. Repeat with another third of the dry ingredients, followed by the remaining sour cream, and finally, the last third of the dry ingredients. Always begin and end with the dry ingredients. This method prevents overmixing the flour and ensures a tender crumb. Mix only until just combined – streaks of flour are acceptable.
Step 6: Create the Chocolate Batter. Gently scrape out approximately half of the prepared banana bread batter into a separate bowl. To the remaining batter in the mixer bowl, add the unsweetened cocoa powder. Fold the cocoa powder into the batter using a spatula until it is evenly incorporated and has a consistent dark chocolate color. Be careful not to overmix, as this can develop the gluten and make the bread tough. You should now have two distinct batters: a plain tahini-banana batter and a chocolate tahini-banana batter.

Step 7: Layer the Batters for Swirl Effect. Now comes the fun part! Using an ice cream scoop or a large spoon, begin layering the plain and chocolate batters into your prepared 8.5×4.5″ loaf pan. Alternate scoops of each batter, creating a checkerboard or random pattern. You will have enough batter to do two full layers in this fashion. This method helps to ensure a beautiful, distinct swirl throughout the loaf. Aim for even distribution.
Step 8: Swirl and Bake. Once all the batter is in the pan, take a butter knife or a skewer and gently swirl the two batters together. Make a few figure-8 motions or S-shapes, ensuring your knife reaches the bottom of the pan to integrate the layers without completely blending them. Remember, less is more when swirling; over-swirling will result in a muddy color rather than a distinct marble pattern. Tap the pan gently on your counter a few times to release any trapped air bubbles. If desired, sprinkle the top generously with white and black sesame seeds. Bake in your preheated oven at 350°F (175°C) for 55-65 minutes, or until a wooden skewer inserted into the center comes out with a few moist crumbs attached, but not wet batter. If the top starts to brown too quickly, loosely tent the loaf with aluminum foil to prevent over-browning. Once baked, remove from the oven and let it cool in the pan for 10-15 minutes before transferring to a wire rack to cool completely.

Expert Baking Tips for Success
Achieving a perfect loaf of banana bread every time involves a few key practices. Keep these tips in mind to ensure your chocolate tahini banana bread turns out flawlessly moist and delicious.
- I highly recommend using a weighing scale and measuring out your ingredients the metric way (grams). Baking is a science, and precision is paramount. Volume measurements (cups) can be notoriously inaccurate due to variations in how ingredients are packed or scooped. Using a scale makes a huge difference to the consistency and accuracy of your baking, ensuring optimal texture and flavor every time.
- Always ensure that all of your ingredients are at room temperature before you start the recipe. This includes butter, eggs, and especially sour cream. Room temperature ingredients emulsify much more easily, creating a smoother, more uniform batter that traps air better during the creaming process. This leads to a lighter, more evenly textured final product. Remember to pull out all necessary ingredients at least 30-60 minutes before you plan to bake.
- Use a light metal pan for this recipe. Dark metal pans tend to absorb more heat, which can cause the sides and bottom of your loaf to scorch or become overly dark before the center is fully cooked. A lighter colored metal pan ensures a more even bake and a beautifully golden-brown crust without burning.
- Be sure to allow your loaf to cool completely on a wire rack before slicing into it. It might be tempting to cut into it while warm, but warm bread is still actively setting its internal structure. If you cut into it too soon, the loaf can fall apart, crumble, or appear gummy inside. Cooling allows the starches to set and the moisture to redistribute, resulting in a clean slice and a perfect texture.
- Do not overmix the batter once the flour is added. Overmixing develops the gluten in the flour, which can lead to a tough, rubbery banana bread. Mix only until the ingredients are just combined, and a few streaks of flour are still acceptable.
- Judge ripeness by appearance: For bananas, the browner, the better! Black spots indicate high sugar content, which means more flavor for your bread.
- Storage is Key: Proper storage will keep your banana bread fresh and delicious. See the FAQ section below for detailed storage instructions.
Frequently Asked Questions
Here are some common questions and helpful answers to ensure your baking experience is smooth and successful:
If you find yourself with under-ripe bananas and an urgent craving for banana bread, there are a few tricks. The simplest method is to place them in a paper bag with an apple or another ripe banana. The ethylene gas emitted by the ripe fruit will accelerate the ripening process, usually within a day or two. For a quicker fix, some “hacks” suggest baking unpeeled bananas in their skins at a low temperature (around 300°F/150°C) for 15-30 minutes until they turn black and soft. While this makes them mashable, it won’t develop the same deep, complex banana flavor that naturally ripened fruit offers. For the absolute best taste, patience with naturally ripening bananas is always recommended.
To maintain the freshness and moisture of your banana bread, proper storage is crucial. Wrap the cooled loaf tightly in plastic wrap or aluminum foil, or store it in an airtight container at room temperature for up to 2 days. If you wish to extend its shelf life, it can be stored in the refrigerator for up to 5 days. For longer storage, this banana bread freezes beautifully. Wrap individual slices or the entire loaf tightly in plastic wrap, then again in aluminum foil, and freeze for up to 3 months. To enjoy, simply defrost slices overnight in the fridge or at room temperature, or gently warm in the microwave or oven.
This recipe is designed for an 8.5×4.5 inch loaf pan, which yields a beautifully tall and domed loaf. If you opt to use a larger 9×5 inch loaf pan, while it might not seem like a significant difference, it will spread the batter thinner. This will result in a flatter loaf that will bake faster, requiring less time in the oven. Be sure to adjust your baking time accordingly and keep a close eye on it to prevent over-baking, which can lead to a dry bread. Always check for doneness with a toothpick test.
While this recipe has not been specifically tested with gluten-free flour, you can often substitute a 1:1 gluten-free all-purpose flour blend (one that contains xanthan gum) for the regular flour. However, the texture might be slightly different. Begin by reducing the baking time slightly and check for doneness, as gluten-free flours can bake differently.
Absolutely! This banana bread is wonderfully adaptable. Feel free to fold in about ½ to 1 cup of chopped walnuts, pecans, or chocolate chips (dark, milk, or white chocolate work well) into the plain batter, the chocolate batter, or both, during Step 6. This adds an extra layer of texture and flavor that complements the tahini and chocolate beautifully.

Instructions
-
Preheat the oven to 350°F/175°C. Grease and line an 8.5×4.5 inch loaf pan with parchment paper, leaving an overhang for easy removal.
-
Mash your ripe bananas until smooth with minor lumps. Set aside. You can use a fork or a potato masher to mash them.
-
In a separate medium bowl, whisk the all-purpose flour, baking soda, and kosher salt together. Set aside.
-
In your mixer with the paddle attachment, beat the room-temperature unsalted butter until creamy. Add both granulated sugar and light brown sugar and beat on medium speed for 2-3 minutes until the mixture is pale and fluffy.
-
Add the vanilla extract, tahini, and the room-temperature egg to the butter mixture, then beat well to fully incorporate. Scrape down the sides of the bowl as needed.
-
Turn the mixer speed to low and add your mashed bananas. Mix just until combined; it might still be slightly lumpy, which is perfectly fine.
-
With the mixer on low speed, add the dry ingredients in three additions, alternating with the room-temperature sour cream. Begin and end with the dry ingredients, mixing only until just combined to avoid overmixing.
-
Scrape out about half of the batter into a separate bowl. To the remaining batter in the mixing bowl, fold in the unsweetened cocoa powder until it is evenly incorporated and has a consistent dark color.
-
Using an ice cream scooper or a large spoon, alternate scoops of the plain and chocolate batters into the prepared loaf pan, creating a checkerboard or random pattern. You will have enough batter to create two layers. Use a butter knife or skewer to gently swirl the two batters together, making a few figure-8 shapes. Ensure the knife reaches the bottom but avoid over-swirling to keep the distinct marble effect.
-
Tap the pan gently on your counter a few times to release any air bubbles. If desired, sprinkle the top generously with white and black sesame seeds.
-
Bake for 55-65 minutes. The banana bread is ready when a toothpick inserted into the center comes out with a few moist crumbs attached, but no wet batter. If the top begins to brown too quickly, loosely tent the loaf with aluminum foil for the remaining baking time. Let cool in the pan for 10-15 minutes before transferring to a wire rack to cool completely.
Notes
Butter: For the best flavor and texture, I recommend using European-style unsalted butter, such as Kerrygold. Its higher butterfat content contributes to a creamier, richer crumb in your finished bake.
Salt: This recipe calls for kosher salt. If you are using fine table salt, remember to halve the amount called for, as it is saltier by volume. (1 teaspoon kosher salt = ½ teaspoon fine salt.)
Sour Cream: If sour cream is unavailable, full-fat plain Greek yogurt or buttermilk can be successfully substituted for a similar moist and tangy result. Ensure it is at room temperature.
Topping: For an extra touch of indulgence, instead of sesame seeds, consider topping this loaf with a rich chocolate ganache. You can find a suitable ganache recipe from my marble loaf cake post.
Storage: Store your cooled banana bread tightly wrapped in plastic wrap or an airtight container at room temperature for up to 2 days, or in the fridge for up to 5 days. For longer storage, freeze individual slices (wrapped in foil or plastic wrap) for up to 3 months and defrost overnight in the fridge when ready to enjoy.
