One Bowl Double Chocolate Banana Bread

This is a deep chocolaty banana bread that is going to get you from desserts to your breakfast. This is a banana bread you’ll want to make again and again.

This banana bread is seriously chocolaty. & the best way to use your over ripe bananas is to make a deliciously healthy banana bread. It is chocolaty and yummy and loved by the kid's too.

The way I chose to make this banana bread seriously chocolate has two parts:

First, I used bittersweet chocolate chips. You can use semisweet, but bittersweet has a deeper, darker chocolate flavor. More chocolate and less sugar means you can pack in the flavor without making the bread too sweet.

Second, I bloomed the cocoa powder.

What Does It Mean To Bloom Cocoa Powder?

Blooming refers to the process of mixing your cocoa powder with a hot liquid. Water, milk, coffee, oil, or in this recipe – butter. If you have a liquid in your recipe with cocoa powder and you heat that liquid, you can bloom your cocoa even if the recipe doesn’t call for it.

When cocoa is mixed with a hot liquid (think about when you make hot cocoa), it dissolves and thickens, losing any graininess or lumps it may have had.

Why Bloom Cocoa Powder?

Because it releases the flavor of the cocoa into your recipe!

Simply stirring cocoa powder into the batter along with the dry ingredients is not going to give you the full chocolate power of the cocoa. It is only when cocoa meets a hot liquid that the flavor compounds are released. This is likely because cocoa powder contains a certain amount of cocoa butter which then dissolves in the hot liquid; however, I haven’t found anything definitive about that.

How To Make Double Chocolate Banana Bread

Ready to make an easy, intensely chocolatey banana bread which you can just about have ready to go before the oven is even done preheating?

First step is to make a parchment sling for your loaf pan since getting this chocolate topped bread out of the pan is not simple otherwise. Though I ran out of my parchment paper, I still managed to get it out of the pan in 1 piece. Just got lucky!

Next, you’re going to melt the butter and stir in the cocoa. Then mash the bananas and whisk together the butter/cocoa and bananas.

In that same bowl, add everything but the flour and chocolate chips – the brown sugar, sour cream, egg, vanilla, salt, and baking soda. Whisk it until smooth. Or smooth-ish since you do want those nice lumps of banana in the batter.

Now you fold in the flour and then half the chocolate chips and pour the batter into the pan. Spread it out evenly and top with the rest of the chocolate chips and bake until your tester comes out clean.

A little rest for the bread, and then use the sling to move the bread to a cooling rack. Wait as long as you can, or at least an hour, and then slice and eat!

Course: Breakfast, Dessert

Cuisine: American

Author: Aaisha Fakih


  • 8 tbsp (4 oz) unsalted butter

  • 1/2 cup (1 1/2 oz) natural cocoa powder

  • 3 large very ripe bananas, about 1 cup mashed

  • 3/4 cup (5 1/2 oz) packed light brown sugar

  • 1/2 cup sour cream

  • 1 large egg

  • 1 tsp baking soda

  • 1 tsp vanilla extract

  • 1/2 tsp table salt

  • 1 cup (5 oz) all-purpose flour

  • 1 1/2 cups (9 oz) bittersweet chocolate chips, divided: 1 cup for the batter, 1/2 cup for the top


  • Preheat oven to 350F.

  • Grease a 9x5 inch loaf pan and make a parchment sling by cutting a piece of parchment paper to the length of the pan and pressing it into the loaf pan so that the ends of the paper hang over the sides of the pan. Grease the parchment paper as well.

  • Melt the butter in a small saucepan over medium heat. Once the butter is melted, stir in the cocoa to make a smooth paste.

  • Mash the bananas with a fork in the large bowl. Stir in the butter and cocoa paste until well combined.

  • Add the brown sugar, sour cream, egg, vanilla, salt and baking soda to the bowl and whisk to combine.

  • Add the flour to the bowl. Use a large silicone spatula to lightly fold over the batter until just combined. Then add 1 cup of the chocolate chips, and fold them in as well.

  • Pour the batter into the prepared loaf pan and smooth it out. Then top the batter with the remaining 1/2 cup of chocolate chips, making sure to spread them out fairly evenly.

  • Bake the banana bread for 50 minutes at 350F. Then reduce the temperature to 325F and bake for 10 minutes more, until a toothpick comes out clean of batter (though you may see some melted chocolate).

  • Cool the bread in the pan for 15 minutes. Then run a knife along the two ends of pan with no parchment and use the sling to pull the bread out onto a cooling rack. Allow to cool for about an hour before attempting to slice so the bread has time to solidify.


  • Slicing: The bread is full of chocolate, which does make neat slices a bit difficult. First, it's best to slice the bread within a few hours of baking so that the top chocolate chips are still soft and you can slice them. Second, the chocolate does tend to stick to the knife, so I like to have a cloth handy to wipe it off as needed. (Also, a little hot water on the knife to warm it up can be quite useful.)

  • Blooming the cocoa: You will note that I added the cocoa to the hot butter before adding both to the bananas. Mixing cocoa with any hot liquid is called blooming and it allows the cocoa flavor to deepen and intensify.

  • Parchment sling: Please use a sling for this recipe! It is very hard to get the bread out of the pan otherwise since there is a lot of soft and melty chocolate on top.
