There are banana breads, and then there are chocolate banana breads. This is the latter—a decadent, fudgy, deeply chocolatey twist on the classic comfort loaf that transforms overripe bananas into something truly extraordinary.
Moist, tender, and bursting with chocolate in every bite, this double-chocolate banana bread is the answer to every chocolate lover’s prayers. The bananas keep the bread incredibly moist while adding natural sweetness, while cocoa powder and chocolate chunks deliver rich, complex chocolate flavor.
Best of all, it comes together in one bowl with no mixer required. Perfect for breakfast, afternoon snacking, or dessert, this loaf is guaranteed to disappear faster than you can say “seconds.”
Instructions
Preheat and Prepare
Preheat your oven to 350°F (175°C). Grease a 9×5-inch loaf pan generously with butter or non-stick spray, or line with parchment paper, leaving overhang on two sides for easy removal.
Mash the Bananas
In a large bowl, mash the overripe bananas with a fork until mostly smooth with a few small lumps remaining. The bananas should measure about 1½ cups.
Combine Wet Ingredients
Add the melted butter, granulated sugar, and brown sugar to the mashed bananas. Whisk until well combined and the sugars have mostly dissolved. Add the eggs, vanilla extract, and sour cream (or yogurt). Whisk until the mixture is smooth and uniform.
Add Dry Ingredients
Sift the flour, cocoa powder, baking soda, and salt directly into the wet ingredients. Use a spatula to fold gently until just combined—a few streaks of flour are okay. Overmixing develops gluten, which can result in a dense, tough loaf.
Add Chocolate Chips
Reserve ¼ cup of the chocolate chips for topping. Fold the remaining ¾ cup chocolate chips into the batter until evenly distributed.
Bake
Pour the batter into the prepared loaf pan and spread evenly. Sprinkle the reserved chocolate chips on top, pressing them lightly into the surface. If desired, sprinkle with flaky sea salt. Bake for 50 to 65 minutes, until a toothpick inserted into the center comes out with a few moist crumbs (not wet batter). If the top is browning too quickly, tent loosely with aluminum foil for the last 15 minutes of baking.
Cool and Serve
Let the bread cool in the pan for 15 minutes, then transfer to a wire rack to cool completely before slicing. For the cleanest slices, let the bread cool completely or even refrigerate for a few hours before slicing. Dust with powdered sugar just before serving if desired.
This Chocolate Banana Bread is the perfect way to use up overripe bananas—rich, moist, and utterly irresistible.
