Chocolate Chip Banana Bread
This full-size loaf has a browned, naturally cracked top and a tender crumb with chocolate throughout. Measuring the mashed banana keeps the batter from getting too wet, while a light-colored 9×5-inch metal pan helps the center bake before the crust gets too dark. Start checking early, but let the center—not the clock—tell you when the bread is done.
Yield: 1 loaf, about 10 thick slices. Prep: 15 minutes. Bake: about 55–70 minutes. Cooling: about 1 hour.
Ingredients for Chocolate Chip Banana Bread

- 1 1/2 cups mashed very ripe banana, from about 3 medium bananas (340g)
- 1 3/4 cups all-purpose flour (210g)
- 1 teaspoon baking soda
- 1/2 teaspoon fine salt
- 1/2 cup unsalted butter, melted and cooled slightly (113g), plus a little for greasing the pan
- 3/4 cup packed light brown sugar (150g)
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 cup semisweet chocolate chips or coarsely chopped semisweet chocolate (170g)

The Right Bananas and Loaf Pan
Use bananas with heavily spotted or browned skins, and measure them after mashing. Three bananas can yield different amounts; more than 1 1/2 cups can leave the center too wet.
The bake-time range is for a light-colored 9×5-inch metal loaf pan. A smaller pan makes a deeper loaf, while dark or glass pans change how quickly the crust browns. Leave parchment overhang on the pan’s long sides to make the cooled loaf easier to lift out.
How to Bake Chocolate Chip Banana Bread
- Prepare the pan: Preheat the oven to 350°F (175°C) with a rack near the center. Grease a light-colored 9×5-inch metal loaf pan and line it with parchment, leaving overhang on the long sides.
- Mix the dry ingredients: Mash and measure 1 1/2 cups banana. In a separate bowl, whisk together the flour, baking soda, and salt. If using large chocolate chunks, reserve a little of the measured flour to coat them before adding them to the batter.
- Mix the wet ingredients: In a second bowl, whisk the slightly cooled melted butter with the brown sugar, eggs, and vanilla. Stir in the banana; small pieces are fine.
- Fold the batter: Add the dry ingredients to the wet ingredients and fold just until no dry flour remains. Gently fold in the chocolate. The batter should be thick and spoonable; continued stirring can make the loaf dense.
- Bake: Spread the batter in the pan and bake uncovered. Begin checking at 50 minutes; expect about 55–70 minutes in the specified pan. The top should be browned and naturally cracked, and the center should look set rather than shiny. A tester inserted near the center should come out clean or with a few moist crumbs, not wet batter.
- Cool and slice: Leave the loaf in the pan for 15 minutes, then lift it onto a wire rack. Cool completely, about 45–60 minutes more, before cutting thick slices so the crumb holds together.
How to Tell When the Center Is Done
Melted chocolate can leave a dark smear on a tester. If the tester hits chocolate, check another spot near the center. Wet batter means the loaf needs more time, even if the crust is already brown. If the top becomes too dark before the center is done, tent it loosely with foil and continue baking.
Serving and Chocolate Variation
Serve thick slices plain, or warm an individual slice and add a little butter. For a less-sweet contrast, replace the semisweet chocolate with the same amount of dark chocolate; the method stays the same.
Storing and Freezing Chocolate Chip Banana Bread
Cool the loaf completely before wrapping it tightly or storing it in an airtight container. Keep it at room temperature for about 2–3 days, checking sooner in a warm or humid kitchen.
For longer storage, wrap the cooled loaf or individual slices tightly, seal, and freeze for about 2–3 months for best quality. Thaw slices at room temperature or warm them in a toaster oven. A room-temperature slice can also be microwaved for about 10–15 seconds.
Nutrition
Approximate nutrition per slice, based on 10 thick slices: 345 calories, 5g protein, 15g fat, and 50g carbohydrates. Per 100g of baked bread: approximately 360 calories, 5g protein, 16g fat, and 53g carbohydrates, assuming a baked loaf weighing about 950g. Values vary with the chocolate used and moisture lost during baking.

Tips
- Use heavily spotted or browned bananas and measure them after mashing.
- Keep the mashed banana to 1 1/2 cups to avoid an overly wet center.
- Use a light-colored 9×5-inch metal pan for the stated baking time.
- Avoid overmixing after adding the flour to help keep the loaf tender.
- If a tester hits melted chocolate, check another spot near the center.
Variations
- Dark Chocolate Banana Bread: Replace the semisweet chocolate with the same amount of dark chocolate.
