I can’t get over how ridiculously soft this Chocolate Chip Sour Cream Banana Bread turns out, with melty chocolate in every slice. One secret ingredient makes it so moist, you’ll want this loaf on repeat.

Jump to Recipe

I’m obsessed with this Chocolate Chip Sour Cream Banana Bread because it hits that sweet spot between tender, rich, and just messy enough to feel worth every crumb. The sour cream gives it this soft, almost melt-in-your-mouth texture that keeps me sneaking back for “one more” slice.

And the chocolate chips? They turn every bite into a little reward.

I love banana bread already, but this version feels more indulgent without trying too hard. Buttery slices, pockets of chocolate, that deep banana flavor I never get tired of.

Honestly, I’d make it just for the smell alone. No regrets.

Ever.

1. Preheat oven to 350°F (175°C). Grease and flour a 9×5 inch loaf pan or line it with parchment paper.

2. In a medium bowl whisk together 1 1/2 cups all purpose flour, 1 teaspoon baking soda, 1/2 teaspoon baking powder, and 1/2 teaspoon salt. Set aside.

3. In a large bowl cream 1/2 cup softened unsalted butter with 3/4 cup granulated sugar and 1/4 cup packed light brown sugar until light and fluffy.

4. Beat in 2 large room temperature eggs one at a time, then stir in 1 teaspoon vanilla extract until blended.

5. Stir in 1 cup sour cream until combined, then fold in 1 cup mashed ripe bananas until evenly incorporated.

6. Gradually add the dry ingredients to the wet mixture and mix until just combined. Do not overmix.

7. Fold in 1 to 1 1/4 cups semisweet chocolate chips and, if using, 1/2 cup chopped walnuts or pecans.

8. Pour batter into prepared loaf pan and smooth the top.

9. Bake at 350°F (175°C) for about 60 to 70 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.

10. Cool the bread in the pan on a wire rack for 10 to 15 minutes, then remove from pan and cool further before slicing.

Equipment Needed

2. 9×5 inch loaf pan (or parchment paper and a pastry brush for greasing)
3. Large mixing bowl and medium mixing bowl
4. Electric mixer or wooden spoon for creaming butter and sugar
5. Whisk for dry ingredients
6. Rubber spatula for folding and scraping the bowl
7. Measuring cups and spoons
8. Potato masher or fork for mashing bananas
9. Cooling rack and toothpick for testing doneness

FAQ

Q: Can I substitute the sour cream? A: Yes. Use an equal amount of plain Greek yogurt for similar tang and moisture, or make a buttermilk substitute with 1 cup milk plus 1 tablespoon lemon juice or vinegar, let sit 5 minutes.

Q: How ripe should the bananas be? A: Use very ripe bananas with lots of brown speckles for the best sweetness and flavor. Overripe bananas are fine and mash easily.

Q: Can I change the amount or type of chocolate chips? A: Yes. Use between 1 and 1 1/4 cups as listed; dark, semisweet, or milk chips all work. For even distribution, toss chips in a tablespoon of flour before folding in.

Q: Are the nuts necessary and can they be toasted? A: Nuts are optional. Toasting them in a dry skillet for 3 to 5 minutes enhances flavor. Chop roughly and fold in at the end to keep texture.

Q: How should I store or freeze the bread? A: Store wrapped at room temperature for up to 3 days, or refrigerate up to 5 days. Freeze cooled slices or whole loaf wrapped tightly for up to 3 months; thaw at room temperature.

Q: Can I make muffins or change pan size, and do baking times change? A: Yes. For 12 standard muffins, bake 18 to 22 minutes at the same temperature. A standard 9×5 loaf pan bakes about 55 to 70 minutes; check with a toothpick inserted in the center for a few moist crumbs.

Chocolate Chip Sour Cream Banana Bread Recipe Substitutions and Variations

All purpose flour: use an equal amount of whole wheat pastry flour for a nuttier, tender loaf, or substitute 1 cup cake flour plus 2 tablespoons all purpose flour for a lighter crumb.
Sour cream: swap with an equal amount of full fat Greek yogurt for similar tang and moisture, or use buttermilk at a 1 to 1 ratio for a slightly thinner batter.
Unsalted butter: replace with melted coconut oil at a 1 to 1 ratio for a hint of coconut, or use neutral vegetable oil at 3/4 cup for every 1 cup butter called for to keep the bread moist.
Eggs: for each large egg, use 1/4 cup unsweetened applesauce for a dairy free option, or whisk 1 tablespoon ground flaxseed with 3 tablespoons water and let sit 5 minutes to make a flax “egg” for a vegan swap.

Pro Tips

1. Use very ripe bananas with lots of brown spots. They mash more easily and give the bread the best banana flavor and natural sweetness, which lets you rely less on added sugar.

2. Bring the eggs, sour cream, and butter to room temperature before mixing. This helps everything combine smoothly so you get a tender, even crumb instead of a dense, gummy loaf.

3. Fold the dry ingredients in just until you no longer see streaks of flour. Overmixing develops gluten and will make the loaf tough. Same goes for folding in the chocolate chips and nuts gently so they stay suspended rather than sinking.

4. If the top is browning too quickly in your oven, tent a piece of foil loosely over the loaf during the last 15 to 20 minutes. That way the center can finish baking without the crust getting too dark.

5. Let the bread rest in the pan for about 10 to 15 minutes, then transfer to a wire rack to finish cooling. Slicing when it is still hot causes the crumb to tear and chocolate to smear. For cleaner slices, chill the completely cooled loaf for 30 minutes before cutting.
