Brown Butter Banana Bread with Chocolate Chips

If you love classic banana bread but want to take it up a notch, this recipe is it. Browning the butter gives it a deep, nutty aroma, while ripe bananas keep it extra moist and flavorful. A touch of sour cream adds creaminess, and the dark chocolate chips melt into little pockets of goodness. Topped with a crunchy turbinado sugar crust, this loaf is cozy, rich, and perfect for any occasion, from weekend baking to sharing with friends over coffee.

Yields

1 (9 x 5-inch) loaf | Serves 8–10

Ingredients

Wet Ingredients

• 1 stick unsalted butter
• 1 ¼ cups light brown sugar, packed
• 1 large egg
• 2 cups ripe banana, mashed (about 4 medium)
• ½ cup full-fat sour cream
• 2 teaspoons vanilla paste

Dry Ingredients

• 1 ½ cups all-purpose flour
• 1 teaspoon kosher salt
• ½ teaspoon baking soda
• 1 teaspoon ground cinnamon

Mix-Ins & Toppings

• ½ cup dark chocolate chips
• 2 tablespoons turbinado sugar

Nonstick cooking spray, for greasing

Instructions

1. Preheat the Oven
   Preheat your oven to 350°F (180°C). Lightly grease a 9 x 5-inch loaf pan with nonstick cooking spray, then line it with parchment paper so it overhangs on the long sides—this will make it easy to lift the bread out later. Give the parchment one more light spray to make sure nothing sticks.
2. Brown the Butter
   In a medium nonstick saucepan, melt the butter over medium heat. Once melted, continue to cook, stirring occasionally, as the milk solids settle and begin to turn golden brown. You’ll notice a toasty, nutty aroma and the butter will deepen to a rich amber color—this usually takes about 3–4 minutes. Remove from the heat as soon as it reaches that point (it can burn quickly), then pour it into a large mixing bowl. Let the butter cool for 10–15 minutes so it doesn’t melt the sugar or cook the egg when mixed..
3. Cream the Butter & Sugar
   Once the butter has cooled, add the light brown sugar to the bowl. Using an electric hand mixer on medium speed, beat the mixture for about 1 minute until smooth and glossy. Add the egg and beat again for 3–4 minutes, or until the mixture becomes lighter in color and fluffy—this step adds air and helps create a tender crumb in the final loaf.
4. Mix the Wet Ingredients
   In a separate medium bowl, mash the ripe bananas until mostly smooth with just a few small lumps for texture. Stir in the sour cream and vanilla paste, mixing until the ingredients are fully blended and silky. This mixture adds moisture and flavor depth to the batter.
5. Combine the Dry Ingredients
   In another bowl, whisk together the all-purpose flour, kosher salt, baking soda, and cinnamon. Whisking helps break up any clumps and evenly distributes the leavening agents, ensuring a consistent rise.
6. Bring the Batter Together
   Switch to a rubber spatula and begin folding the wet and dry ingredients into the creamed butter mixture. Start by adding about one-third of the dry ingredients, folding gently until just combined. Next, add half of the banana mixture, folding again. Repeat this process, alternating between dry and wet, and end with the dry ingredients. Take care not to overmix—the goal is to stop as soon as there are no visible streaks of flour. Overmixing can lead to a dense or tough loaf.
7. Fold in the Chocolate
   Add the dark chocolate chips and fold them in gently until they’re evenly distributed throughout the batter. If you like a few melty bits on top, set aside a tablespoon of chips to sprinkle over the surface before baking.
8. Bake
   Pour the batter into the prepared loaf pan, smoothing the top with an offset spatula to help it bake evenly. Sprinkle the turbinado sugar evenly over the surface—this creates that signature crunchy, golden crust. Bake on the center rack of the oven for 60–70 minutes, or until the top is deeply golden and a toothpick inserted into the center comes out clean or with a few moist crumbs. If the top starts to brown too quickly, tent the loaf loosely with foil during the final 15–20 minutes of baking. An instant-read thermometer should register 200–205°F in the center when it’s done.
9. Cool & Slice
   Place the loaf pan on a wire rack and let the bread cool for at least 1 hour—this helps the crumb set fully and prevents it from crumbling when sliced. Use the parchment overhang to gently lift the banana bread out of the pan. For the cleanest slices, let it cool another 10–15 minutes before cutting. Serve slightly warm or at room temperature. It’s especially good with a cup of coffee or tea, and it keeps beautifully for a few days (if it lasts that long!).

Let’s Talk Ingredients: Why They Matter

Brown Butter
Browning the butter adds a toasty, nutty depth of flavor that sets this banana bread apart from the usual. It makes the loaf smell incredible even before it hits the oven.

Bananas
Very ripe bananas are key here — the browner the better. They bring natural sweetness, moisture, and that signature banana flavor. Mashing them smooth ensures an even texture.

Sour Cream
A little sour cream adds moisture and richness, giving the bread a tender crumb without being heavy.

Dark Chocolate Chips
These melt into rich pockets throughout the loaf, adding a touch of indulgence to every slice.

Turbinado Sugar
Sprinkling turbinado sugar on top before baking gives the crust a beautiful crunch and sparkle.
