Why You'll Love this Double Chocolate Banana Bread
It's super, super moist. The ripe bananas and buttermilk keep the bread extra moist.
It's as chocolatey as it possibly can be. The banana bread uses Dutch process cocoa powder for a rich chocolate flavor and it's also packed full of chocolate chips.
It stays fresh for days. This banana bread will keep it's perfect moist texture for up to four days. I do recommend refrigerating it after day two.

Ingredients for Double Chocolate Banana Bread

- All purpose flour
- Bananas- the more overripe the better
- Eggs
- Cocoa powder- I recommend using Dutch process cocoa powder because it has a deeper more chocolatey flavor
- Granulated sugar
- Butter- make sure it's softened
- Buttermilk- makes this banana bread super moist
- Chocolate chips- semi-sweet chocolate chips add extra chocolatey goodness to this banana bread
- Vanilla- I recommend vanilla bean paste for the best flavor
- Baking soda- leavens this banana bread and helps it to have a fluffy texture

Step By Step Instructions
(See recipe below for full measurements and baking time.)
STEP ONE: Mash your bananas
STEP TWO: Cream softened, unsalted butter and sugar together.
STEP THREE: Add in eggs and vanilla and combine.
STEP FOUR: Mix in mashed bananas and buttermilk.
STEP FIVE: In a small bowl whisk together all purpose flour, cocoa powder, baking soda and salt. Add the dry ingredients to the wet ingredients and combine.
STEP SIX: Lastly mix in semisweet chocolate chips.
STEP SEVEN: Grease and line 9 x 5 inch loaf pan with parchment paper. Pour batter into prepared pan. Bake the banana bread. After baking, let the banana bread cool in the pan for 20 minutes and then transfer to a cooling rack to completely cool. I recommend waiting until the banana bread is completely cooled before serving for the best taste. (It tastes more chocolatey and moist after it is completely cooled!) Enjoy! Store leftovers in an airtight container for up to four days. Refrigerate after day two.

FAQs
Can this be made gluten free or with whole wheat flour? I have not tested this recipe with anything other than all purpose flour so I'm not sure how it would come out. If you do please let me know!
Do I have to use Dutch process cocoa powder? No you can use regular cocoa powder, but Dutch process will give you an extra chocolatey banana bread!
Can I substitute the buttermilk with something else? No, the buttermilk is what makes this bread extra moist and gives it its perfect texture.
How long will it stay fresh for? It'll stay fresh for up to four days. Store leftovers in an airtight container and refrigerate after day two.

Pro Tips
Make sure all your wet ingredients are room temperature. This really helps the banana bread to have the best texture.
Don't skip lining the loaf pan with parchment paper. The parchment paper helps the bread to have a better shape.

How many chips do you put on the top ????
I have the same question.... How many chocolate chips do you put on top and when do you put them on top
Love this cake. Not a bread. Dense and amazing. I didn't have buttermilk so I substituted 3/4 cup Labne and some cream. I use labne (a thicken. dense yogurt ) in baking instead of sour cream or yogurt. I will make this bread/cake again and again. Thanks for the recipe.
Hi there, I will notate on the recipe but I did about 2-3 tablespoons. Just a few for looks!
Hi Sally, I did 2-3 tablespoons. I will be notating it on the recipe. You can put them on before baking or after. I choose to do after so they don’t melt all the way into the banana bread. I hope this helps!
Can I substitute all purpose flour with wholewheat flour?
Hi Mala, I'm not sure if the consistency of the banana bread will be the same with whole wheat flour.
I whipped this bread up after work yesterday. So easy. So moist. So delicious. I haven't even finished eating this first loaf and I'm already excited to make it again. Thank you for this amazing recipe!
Wow, this is the best banana bread I haver made. So moist and flavorful.Never going back to regular banana bread. I didn't have buttermilk,so instead I used heavy cream. It still came out delicious. Thanks for the recipe
How size the loaf pan?
Absolutely amazing! Every recipe I make on this website is AMAZING! I added more chocolate chips on top and the loaf was moist for so long! It was amazing. I will be making it again! Thank you!
