Banana bread is one of my favorite quick breads! I love using the bananas for the added sweetness and moisture, and I also love how versatile it is. My original Sourdough Banana Bread recipe is baked in muffin form and has the option of using chocolate chips or other mix-ins like walnuts or shredded coconut. For this recipe, I decided to take it up a notch and really infuse the banana bread with rich, gooey, chocolatey flavor by adding cocoa powder and chocolate chips. This banana bread is so chocolatey and delicious, you are going to love it!

Ingredients for Sourdough Chocolate Banana Bread

- Vanilla extract – The vanilla will help enhance the flavor of the chocolate.
- Bananas – Use very ripe bananas, the riper they are, the more sweetness they will add to the bread.
- Sourdough discard – Cold or room temperature discard will work. I use mine directly from the fridge.
- Milk – You can use whatever type of milk you have on hand.
- Baking soda- This is added to leaven the banana bread.
- Salt – Using salt in baked goods brings out the flavor. You can use whatever type of salt you have on hand.

Directions to make Sourdough Chocolate Banana Bread

Step 1: Beat the butter and the sugars until light and fluffy in a large bowl. You can also use your stand mixer with the paddle attachment.

Step 2: Mix in the wet ingredients: eggs, sourdough discard, milk and vanilla.
Add in the bananas and mix. To ensure there are no chunks in the bread, pre-mash the bananas before adding.

Step 3: Mix in the dry ingredients: flour, cocoa powder, salt, and baking soda and stir to combine. Dump into the batter. Gently mix until just combined. Do not over mix here to ensure the banana bread stays tender.
Lastly, gently fold in chocolate chips.

Step 4: Spray a 9” x 5” pan with non-stick spray and pour in the batter. Add additional chocolate chips on top if you would like.
Bake for 1 hour in a preheated 350℉ oven or until a toothpick comes out clean.

Step 5: Once baked, set on a cooling rack to cool before slicing.
Recipe Tips
- Mash the bananas before adding them to the batter to ensure there are no chunks in the bread.
- Cream the butter and sugars completely before you add the remaining ingredients
- Do not over-mix! This is the most important rule to follow to ensure that the bread stays tender and doesn’t turn out tough. It’s okay if the batter is a little lumpy, it does not need to be smooth. The more you mix the batter the more gluten development happens, which results in a tough bread.
- Do not overbake the bread. Check the bread with a toothpick or cake tester and as soon as it comes out clean, it is ready. All ovens are different, so your total time for baking may vary slightly.

How to store Sourdough Chocolate Banana Bread
To store the Sourdough Chocolate Banana bread, wrap it up with aluminum foil or plastic wrap or store in an airtight container once completely cooled. The bread can be left at at room temperature for several days. Or, if kept in the fridge it will last for about a week.
To freeze, double-wrap the loaf when it’s completely cooled and then add it to a freezer bag. You can store it in the freezer for up to three months. When you would like to eat the banana bread, remove it from the freezer and let it defrost on the counter.

Thanks so much!
Hi! Any recommendations on making this dairy free?
Full-fat coconut milk in place of milk and plant-based butter 🙂
Can you use frozen bananas?
Yes! I just recommend thawing them so they are easy to mash and drain off the excess liquid.
This is my go to for the family. It’s fudgy , it’s decadent, it’s delicious. I ran out of cows milk and used coconut, it turned out just as good as the original recipe.
Love all of your recipes.
My husband said this was the best banana bread he has ever had!! And he has had many kinds! I agree. We ate it warm so it was like dessert after dinner, and then again room temperature for breakfast the next day. Both incredible! The flavor gets better the longer it sits. I would not change a single thing. Moist and delicious!!!
Thanks so much Kristin!

Absolutely decadent!!! I made this recipe into muffins today, and sampled one just as soon as they cooled. I’m telling you, I believe this is the best recipe I’ve baked in my lifetime, and I’ve done a lot of baking. It must be the bananas, coupled with the semi-sweet chocolate chips, that give them this incredibly moist texture. Take my word for it when I say this is a must-try recipe!
