• ▢ 2 large eggs 100 grams
• ▢ 1 teaspoon pure vanilla extract 4 grams
• ▢ ½ cup sour cream 114 grams
• ▢ 1 cup bittersweet chocolate chips 170 grams, divided

• Preheat oven to 350°F, grease 9×5-inch loaf pan with nonstick spray, and set aside.

• In a medium bowl, sift together the flour, cocoa, baking soda, and salt. Set aside.

  1 cup all-purpose flour, ½ cup unsweetened Dutch-process cocoa powder, 1 teaspoon baking soda, ½ teaspoon kosher salt

• In a large bowl, combine the mashed bananas with the melted butter. Stir to combine.

  3 ripe bananas, ½ cup unsalted butter

• Add the brown sugar, egg, vanilla, and sour cream. Mix well.

  1 cup brown sugar, 2 large eggs, 1 teaspoon pure vanilla extract, ½ cup sour cream

• Gradually add dried ingredients to the large bowl of wet ingredients. Do not overmix.

• Fold in the chocolate chips, reserving ¼ cup for the top of the bread.

  1 cup bittersweet chocolate chips

• Pour the batter into the prepared pan and sprinkle with the remaining chocolate chips.

• Bake for 60 minutes. Oven times may vary. Check for doneness at 50 minutes, and every 5-10 minutes after that until a toothpick comes out batter free.

• Allow to nearly completely cool to room temperature before removing from pan.

• Use very ripe bananas for the richest and sweetest flavor.
• Bake the bread in a pre-heated oven so that it cooks evenly all the way through.
• Be careful to not over-bake your banana bread.It’s done when a tester inserted into the center of the loaf comes out with a few moist crumbs attached.

Storage: Store double chocolate banana bread in an airtight container at room temperature for up to 4 days, in the refrigerator for up to 1 week, or in the freezer for up to 4 months.

I usually make a plain ole walnut banana bread, but wanted something new. This was amazing! Especially if you like chocolate which we do, it was perfect. I didn’t use Hershey’s cocoa powder and mini chocolate chips. Turned out perfect.

Thank you for this amazing recipe. It looked so good, I doubled it and baked in a 9×13 pan until it was done, but I’m not really sure how long it took. I used my frozen bananas that I throw in the freeze when I have extras that are getting very ripe. Since I didn’t have sour cream, I substituted whole milk plain Greek yogurt. To cut down on the sugar a bit since the bananas as a great natural sweetener, I I didn’t pack down the brown sugar as was a little stingy with measuring. Also, I cut down on the chocolate chips, using 1/2 the amount of mini semi-sweet chips because that’s what I had on hand. This recipe is a definite keeper. I love that the outside edges got a little crispy and tasted caramelized!

My son-in-law loves chocolate so when I saw your recipe I had to try it. My oven tends to run hot so I shortened the time to 45 minutes and added more minutes after the toothpick test. Because it is so moist I know now that it needs all the time listed and maybe more. This bread is better than the chocolate muffin recipe I have! I could eat a whole loaf by myself ;oP BTW my SIL loved it!

We love anything with bananas. The 1st time I made this, I used a loaf pan, but my son suggested to use mini loaf pans, I doubled the recipe, I only have 2 pans and the rest I put them in muffin cups/liners. No turning back, will use the loaf mini pans again. This is so deliciously moist. Thanks you Cookie Rookie/Becky.

I’ve made this before and it’s amazing!

Can I use regular (natural) cocoa powder, like Hershey’s, instead of a dutch processed cocoa powder? Thank you.

I really liked this recipe, it turned out lovely and is really tasty, but I think next time I make it I will try and use 4 or 5 bananas and hope it turns out as well. It didn’t have a lot of banana flavor and we love that in this house.
