Chocolate Banana Bread Recipe tastes like a rich, fudgy brownie that ran off and married your favorite banana bread, and they invited cocoa nibs to the party. It works for busy parents, college students, and anyone who wants a cozy treat in about 1 hour from start to finish. I first baked this on a rainy Sunday in a tiny apartment kitchen, and my neighbors still talk about that smell in the hallway.

Ingredients You’ll Need
Bananas & Dairy
- 3 large very ripe bananas, mashed (the more brown spots, the sweeter and more flavorful)
- 1/2 cup plain Greek yogurt or sour cream (adds moisture and tenderness)
- 1/2 cup unsalted butter, melted and slightly cooled
- Use salted butter if you like; just reduce added salt a bit.
- 2 large eggs, at room temperature
- 1 teaspoon vanilla extract (use pure vanilla for best flavor)
Dry Ingredients
- 1 1/2 cups all-purpose flour
- You can swap up to half with whole wheat flour; expect a slightly denser loaf.
- 1/2 cup unsweetened cocoa powder
- 3/4 cup granulated sugar
- 1/4 cup light brown sugar, packed (adds moisture and a hint of caramel note)
- 1 teaspoon baking soda
- 1/2 teaspoon baking powder
- 1/2 teaspoon fine sea salt
Chocolate & Mix-ins
- 1 cup chocolate chips or chunks
- Use semi-sweet for balance, milk chocolate for extra sweetness, or dark chocolate for a richer loaf.
- 1/2 cup chopped walnuts or pecans (optional, for crunch)
- 2 tablespoons mini chocolate chips for topping (optional but very pretty)
Pantry Shortcuts & Substitutions
- No yogurt or sour cream: use 1/2 cup buttermilk or 1/2 cup milk mixed with 1 teaspoon vinegar and let it sit 5 minutes.
- No butter: use 1/2 cup neutral oil like canola or avocado oil; the loaf stays extra moist.
- Need it dairy free: use oil instead of butter and a thick dairy-free yogurt.
Equipment List
- 1 standard 9 x 5 inch loaf pan
- Parchment paper or nonstick spray
- 2 mixing bowls
- Whisk and rubber spatula
- Measuring cups and spoons
- Cooling rack
- Toothpick or thin knife for doneness check
Tips & Tricks
- Use bananas with lots of brown spots; pale yellow bananas do not give enough sweetness or flavor.
- Mash bananas well, but leave a few small lumps for texture.
- Bring eggs and dairy to room temperature so the batter mixes smoothly.
- Sift cocoa powder if it looks clumpy to avoid dry pockets of cocoa.
- Do not overmix once you add flour; stir just until no dry streaks show to keep the crumb tender.
- Toss chocolate chips with a teaspoon of flour before folding them in so they spread evenly.
- Line the loaf pan with a parchment sling so you lift the bread out easily.
- Bake on the middle rack so the top does not brown too fast.
- Start checking for doneness at 50 minutes since ovens vary.
- Let the loaf cool at least 20 to 30 minutes before slicing so it does not crumble.
How to Make Chocolate Banana Bread
1: Prep the pan and oven
Preheat your oven to 350°F (175°C). Grease a 9 x 5 inch loaf pan and line it with a strip of parchment that hangs over the long sides for easy lifting. Lightly grease the parchment as well so nothing sticks.
2: Mash the bananas
Peel the bananas and place them in a large mixing bowl. Use a fork or potato masher and mash until mostly smooth with a few small lumps. Measure to make sure you have about 1 1/2 cups mashed banana for best texture.
3: Mix the wet ingredients
To the mashed bananas, add melted butter, Greek yogurt or sour cream, eggs, sugar, brown sugar, and vanilla. Whisk until the mixture looks smooth and glossy and the sugar starts to dissolve. Scrape the sides of the bowl so everything blends evenly.
4: Combine the dry ingredients
In a separate bowl, whisk together flour, cocoa powder, baking soda, baking powder, and salt. Break up any cocoa clumps with the whisk. This step keeps the leavening and cocoa spread evenly through the batter.
5: Bring the batter together
Pour the dry mixture into the banana mixture. Use a spatula and fold gently until you no longer see dry flour. Stop as soon as the batter looks combined so the loaf stays soft and tender.
6: Add chocolate and nuts
Fold in the chocolate chips and nuts, if you use them. Sprinkle the extra mini chocolate chips over the top of the batter in the bowl or after you pour it into the pan. Spread the batter into the prepared loaf pan and smooth the top.
7: Bake
Place the pan on the middle rack of the oven. Bake for 55 to 65 minutes, until a toothpick inserted in the center comes out with a few moist crumbs but no wet batter. If the top browns too quickly, tent a piece of foil loosely over the pan during the last 10 to 15 minutes.
8: Cool and slice
Set the pan on a cooling rack and let the bread cool in the pan for about 15 minutes. Use the parchment sling and lift the loaf out onto the rack. Let it cool another 15 to 20 minutes, then slice with a sharp serrated knife and serve.
