Full Ingredients

For the Banana Bread Loaf

• 3 large very ripe bananas, peeled and mashed (about 1 1/2 cups / 340 g)
• 1/2 cup (113 g) unsalted butter, melted and slightly cooled
• 2 large eggs, at room temperature
• 3/4 cup (150 g) packed light brown sugar
• 1/4 cup (50 g) granulated sugar
• 2 tsp pure vanilla extract
• 1/4 cup (60 g) full-fat sour cream or plain full-fat Greek yogurt
• 1 1/2 cups (190 g) all-purpose flour, spooned and leveled
• 1 tsp baking soda
• 1 tsp ground cinnamon
• 1/2 tsp fine sea salt or table salt
• 3/4–1 cup (130–170 g) semisweet chocolate chips, mini or regular (optional)

For the Crackly Sugar Top

• 1 1/2 tbsp granulated sugar
• Pinch of ground cinnamon (optional, for extra aroma)

Step-by-Step Instructions

Step 1: Prep your pan and preheat the oven

Preheat your oven to 350°F (175°C) with a rack in the center position. Lightly grease a 9 x 5 inch (23 x 13 cm) loaf pan with butter or nonstick spray. For easiest removal, line the pan with a strip of parchment paper that overhangs the two long sides like a sling, then lightly grease the parchment as well. Set the pan aside.

Step 2: Mash the bananas

Peel the bananas and place them in a large mixing bowl. Using a fork or potato masher, mash until mostly smooth with just a few small lumps left for texture. You should have about 1 1/2 cups (340 g) of mashed banana. If you are a little over or under by a tablespoon or two, that is fine, but try to be close for the best texture.

Step 3: Mix the wet ingredients

To the bowl with the mashed bananas, add the melted butter (make sure it is warm, not hot), eggs, brown sugar, 1/4 cup granulated sugar, vanilla extract, and sour cream or Greek yogurt. Whisk until the mixture is smooth and well combined, with no streaks of egg. This is your wet mixture and it should smell strongly of banana and vanilla.

Step 4: Whisk together the dry ingredients

In a separate medium bowl, whisk the flour, baking soda, cinnamon, and salt until everything is evenly distributed. This step helps prevent pockets of baking soda or spices and keeps your loaf tender and evenly risen.

Step 5: Combine wet and dry without overmixing

Pour the dry ingredients into the banana mixture. Using a spatula or wooden spoon, gently fold the dry ingredients into the wet just until you no longer see visible streaks of flour. Scrape the bottom and sides of the bowl as you go. The batter should be thick and slightly lumpy; it is important not to overmix, or the bread can become dense.

If you are using chocolate chips (and/or a handful of chopped nuts), sprinkle them over the batter and fold in just 2–3 times until they are distributed. Overmixing at this point can cause the loaf to be tough and can sink the chips to the bottom.

Step 6: Add the crackly sugar top and bake

Scrape the batter into the prepared loaf pan and smooth the top with a spatula so it is level. In a small bowl, stir together the 1 1/2 tbsp granulated sugar and a tiny pinch of cinnamon (if using). Sprinkle this mixture evenly over the surface of the batter. This thin layer of sugar will bake into a crackly, shiny crust.

Place the pan on the center rack of the preheated oven and bake for 55–65 minutes. Begin checking around 50 minutes. The banana bread is done when the top is deep golden brown and a toothpick inserted into the center comes out mostly clean with a few moist crumbs, but no wet batter. If the top is browning too quickly before the center is done, loosely tent the loaf with foil for the last 10–15 minutes of baking.

Step 7: Cool, slice, and serve

Remove the pan from the oven and place it on a wire rack. Cool the loaf in the pan for 15 minutes to set the structure. Then use the parchment sling to carefully lift the bread out of the pan and place it directly on the rack.

Let the banana bread cool for at least 45 minutes before slicing; it will slice more cleanly and stay moister. Use a sharp serrated knife to cut into thick slices. Serve slightly warm or at room temperature, plain or with a little butter, peanut butter, or cream cheese.

Pro Tips

• Use very ripe bananas: The best bananas for this recipe are heavily speckled or mostly brown on the outside. The riper they are, the sweeter and more flavorful your loaf will be.
• Measure flour carefully: Too much flour makes banana bread dry. For accuracy, fluff your flour, spoon it into the measuring cup, and level it with a knife, or use a scale (190 g).
• Do not overmix: Once the flour goes in, mix gently and stop as soon as the batter is combined. Overmixing develops gluten and leads to a tough, rubbery loaf.
• Check doneness in the center: Insert a toothpick into the tallest part of the loaf. A few moist crumbs are ideal; if you see wet batter, bake a bit longer, checking every 5 minutes.
• Let it rest before slicing: It is tempting to cut into it right away, but cooling helps the crumb set, so the slices stay tender and do not fall apart.

Variations

• Nutty banana bread: Fold in 1/2 cup (55 g) chopped walnuts or pecans along with, or instead of, the chocolate chips for crunch and a toasty flavor.
• Chocolate swirl banana bread: Remove 1 cup of the finished batter and mix it with 2 tbsp unsweetened cocoa powder and 1–2 tsp milk. Dollop plain and chocolate batters alternately in the pan and swirl with a knife.
• Cinnamon streusel topping: Skip the sugar sprinkle and instead top with a quick streusel made from 3 tbsp flour, 3 tbsp brown sugar, 1/2 tsp cinnamon, and 2 tbsp cold butter rubbed into crumbs.

Storage & Make-Ahead

Once completely cool, wrap the banana bread tightly in plastic wrap or store in an airtight container.

Room temperature: Keeps well for 3 days at cool room temperature. For best texture, store at room temperature rather than in the refrigerator.

Refrigerator: If your kitchen is very warm, you can refrigerate it for up to 5 days. Bring slices to room temperature or warm gently in the microwave or toaster oven before serving.

Freezer: Wrap the whole loaf tightly in plastic wrap and then in foil, or wrap individual slices and place them in a freezer bag. Freeze for up to 3 months. Thaw overnight at room temperature, or warm slices directly from frozen in a low oven or toaster oven.

This banana bread also works well for making ahead: bake the night before, cool completely, and store tightly wrapped. The flavors deepen by the next day.

Nutrition (per serving)

Approximate values per slice (1/10 of the loaf), without optional chocolate chips: about 290 calories, 11 g fat, 45 g carbohydrates, 3 g protein, 2 g fiber, and 22 g sugar. With 1 cup of chocolate chips, each slice is closer to 350 calories and 15 g fat. These numbers are estimates and will vary with exact ingredients and portion sizes.
