    Banana bread is a staple recipe in many kitchens. Even my friends who don't like to bake often tend to have a go-to banana bread recipe handy for when that bunch of bananas sitting on the kitchen counter go uneaten every now and again.

    Well, now I'm bringing you a handy variation on your go-to banana bread recipe with this Marbled Chocolate Banana Bread.

    This recipe is deceivingly easy to put together and makes for a delectable change of pace from classic banana bread. This Chocolate Banana Bread is moist and well-balanced between the chocolate and the sweetness of the overripe bananas. You're gonna love it!

    Chocolate + Banana = a Match Made in Heaven

    To be honest, I'm not the biggest fan of fruit plus chocolate together.

    Chocolate and banana, on the other hand, is clearly an exception. This pairing is one of those quintessential flavor combos that just makes everyone smile. So, I M now sharing a tried-and-true, delicious and super easy-to-bake recipe that highlights these flavors so well.

    The secret to this Marbled Chocolate Banana Bread

    Putting this chocolate banana bread recipe together is a lot easier than it may look! It starts with making my easy Banana Bread batter. (If you are out of baking soda, try my popular Banana Bread (without baking soda).)

    TIP: Don't have brown bananas? Use this simple method of ripening your bananas using your oven for a quick turn around.

    After the batter is all mixed, divide it in half by scooping half the batter into a clean bowl, leaving the remaining half in the mixing bowl.

    Add ¼ cup unsweetened cocoa powder to one of the batters. Fold in using a spatula or wooden spoon until well combined and no dry spots appear.

    Scoop out about ¼ cup of the plain banana bread batter and place in the bottom of the prepared loaf pan. Then scoop the same amount of the chocolate batter and place next to the plain batter dollop. Continue alternating the dollops of batter, layering them on top of one another until you have used up all the batter.

    Using a butter knife, swirl the batters together gently. Sprinkle the top with chocolate chips then bake .

    Tips for Making Marbled Chocolate Banana Bread

    • To mash the bananas, simply place the peeled bananas in a bowl and mash with a fork. No fancy potato masher or other equipment needed. I like to leave some pieces of banana in there – feel free to mash to whatever consistency suits you best! I typically need about 3 to 4 medium to large bananas for the amount specified in the recipe
    • I use an 8×4 loaf pan, whereas I’ve seen many other recipes call for 9×5. This isn’t the hugest of deals, but my personal preference is to have a taller loaf of banana bread rather than a shorter, denser loaf. Feel free to use whichever size you have on hand
    • When swirling the chocolate and plain banana bread batters together, resist temptation to keep swirling. Swirl only once through top to bottom of the pan. If you swirl too much the batters will blend together and you'll lose the marbling effect
    • Don't like bananas? Try my Moist Vanilla Chocolate Marble Pound Cake (Loaf) instead.

    US Customary - Metric

    Instructions

    • Preheat oven to 350ºF (180ºC). Grease a 8×4 loaf pan with butter or line with parchment paper and set aside.
    • In the bowl of a stand mixer, cream together the butter, sugar, eggs and vanilla until well blended and smooth.
      ½ cup unsalted butter, 1 cup granulated sugar, 2 eggs, 2 teaspoons vanilla extract
    • Stop the mixer, add in the mashed bananas and stir until well combined.
      1 ¼ cups mashed overripe banana
    • With the mixer off, add to the bowl the flour, baking soda and salt, mixing until just combined.
      1 ½ cups all-purpose flour, 1 teaspoon baking soda, 1 teaspoon kosher salt
    • Add in the sour cream and blend well.
      ½ cup full-fat sour cream
    • Pour half the batter into a clean bowl and add to it the cocoa powder. Stir until well combined and no dry spots appear.
      ¼ cup unsweetened cocoa powder
    • With a large ice cream scoop or a ¼ cup measuring cup, scoop out and dollop into the corner of the prepared pan the plain batter.
    • Repeat for the chocolate batter, placing the dollop next to the first.
    • Repeat this pattern, adding alternating dollops of plain then chocolate batter to the loaf pan, layering them on top of each other, until there’s no batter remaining.
    • Using a butter knife, gently swirl the top of the batter. Refrain from swirling too much otherwise the batters will get mixed together and muddled, losing the marbled effect.
    • Bake in preheated oven for 1 hour or until toothpick inserted into the center comes out clean. Allow to cool before removing from the loaf pan and slicing

    Notes

    • Once completely cool, wrap the loaf tightly with plastic wrap and store at room temperature up to 4 days
    • If you have leftovers, store them tightly wrapped in plastic wrap in the freezer for up to 3 months

      I cannot thank you enough for sharing this 10 out of 10 banana bread recipe. I am over the moon because I have been baking my whole life, and now, at 62 years old, I can stop my life long search for the ultimate banana bread recipe. Couldn't find a banana bread recipe that I felt was outstanding until I baked this recipe. It is absolutely 100% the very best banana bread I have ever tasted in my life. Nothing I've ever had tops this recipe, nothing even comes close in comparison. Didn't even put the chocolate chips on top because I wanted to make sure I liked it first, and didn't want to waste the chocolate chips in case it didn't taste very good. So even without the chips, this banana bread is a literal slice of heaven, LOL! Thank you 😊

      Can I use olive oil instead of butter?

        I would not recommend using olive oil. The flavor is strong and will impact the flavor of the baked banana bread. Instead try using vegetable oil, canola oil, or avocado oil, as these do not have a flavor.
