Banana Bread Recipe for 9×5 Pan: Perfectly Moist Loaf Every Time

This recipe delivers on its promise of a perfectly moist loaf every time, with a golden crust that cracks just right.

I developed this method after years of testing, focusing on the ideal balance of ripe bananas, butter, and a touch of sour cream for that signature tenderness.

The 9×5 pan ensures even baking, while precise oven temperature and timing create a loaf with a soft crumb and rich banana flavor.

No dry, dense results here—just consistent, bakery-quality banana bread that stays fresh for days.

The bananas are key here. Use ones that are heavily speckled or entirely brown—they’re sweeter and mash more easily. I usually grab mine from Whole Foods or the local farmers market when they’re on sale. The butter should be unsalted so you control the sodium. Land O’Lakes or Kerrygold are reliable brands for consistent results.

No sour cream? Plain Greek yogurt at the same amount works just as well. Out of walnuts? Pecans or chocolate chips make great add-ins. If you’re avoiding nuts, leave them out entirely. The cinnamon is optional but adds a nice warmth—Penzeys has a great Ceylon variety if you want to splurge.

This loaf stays fresh at room temperature for 2-3 days, wrapped tightly in foil or plastic. For longer storage, slice and freeze for up to 3 months (thaw slices as needed). The flavor actually deepens after a day.

Step-by-Step Instructions for Banana Bread in 9×5 Pan

Here is the tested method that guarantees a perfectly moist, evenly baked loaf.

Step 1: Prepare the Wet Ingredients

In a large bowl, mash the 3 whole Ripe Bananas until smooth with only a few small lumps remaining. I find a potato masher or the back of a fork works best for this. The bananas should be very ripe with plenty of brown spots for maximum sweetness and moisture.

Add the 0.5 cup Unsalted Butter (melted and cooled), 0.75 cup Granulated Sugar, 2 whole Large Eggs, 0.25 cup Sour Cream, and 1 tsp Vanilla Extract. Whisk until fully combined and the mixture looks slightly pale. The butter should be just warm to the touch—too hot and it will cook the eggs.

Step 2: Combine the Dry Ingredients

In a separate medium bowl, whisk together the 1.5 cups All-Purpose Flour, 1 tsp Baking Soda, 0.5 tsp Salt, and 0.5 tsp Ground Cinnamon. This ensures the leavening agent is evenly distributed, which prevents pockets of metallic taste in the finished loaf.

Make a well in the center of the dry ingredients. This classic technique helps prevent overmixing when you combine the wet and dry components, which would make the bread dense. The cinnamon adds warmth, but you can omit it if you prefer a more traditional flavor.

Step 3: Mix Wet and Dry Components

Pour the wet mixture into the well of the dry ingredients. Using a silicone spatula, fold the ingredients together just until you see no more streaks of flour. The batter will be thick and slightly lumpy—that’s exactly what you want.

If using, fold in the 0.5 cup Chopped Walnuts at this stage. I recommend toasting them lightly first to enhance their flavor, but this is optional. Overmixing at this point would develop the gluten in the flour, resulting in a tough, chewy bread instead of a tender one.

Step 4: Bake Until Golden and Tested

Pour the batter into a greased 9×5-inch loaf pan and smooth the top with the spatula. Bake in a preheated 350°F oven for 55-65 minutes, or until the top is golden brown and a toothpick inserted in the center comes out clean or with just a few moist crumbs.

About halfway through baking, I like to tent the pan loosely with foil to prevent the top from over-browning while the center finishes cooking. The bread is done when the internal temperature reaches 200-205°F on an instant-read thermometer.

Step 5: Cool Properly Before Slicing

Remove the pan from the oven and let the bread cool in the pan for 10 minutes. This brief rest allows the loaf to set slightly so it doesn’t fall apart when you transfer it. Then, turn it out onto a wire rack to cool completely.

Wait at least 1 hour before slicing. I know it’s hard to resist, but cutting too soon will result in a gummy texture. The bread will continue to cook slightly from residual heat, and cooling completely ensures clean, even slices with that perfect moist crumb.

Flavor Customization for banana bread recipe for 9×5 pan

Spiced Up Version

Add ½ tsp nutmeg and ¼ tsp allspice to the dry ingredients for a warm, aromatic twist. I love foraging for wild cinnamon basil to infuse into the batter—it adds a unique herbal note that pairs beautifully with the banana. 🌿

Chocolate Lovers

Fold in 1 cup chocolate chips or chunks at the end for a decadent treat. I prefer Ghirardelli 60% cacao for the perfect balance of sweetness. For extra richness, sprinkle a handful on top before baking.

Nutty Variations

Swap walnuts for pecans or hazelnuts for a different crunch. Toast them in a dry pan over medium heat for 5 minutes to enhance their natural oils. I often pick up fresh nuts at local farmers markets.

Tropical Twist

Add ½ cup diced pineapple and ¼ cup shredded coconut to the batter for a taste of the tropics. The pineapple adds moisture, so reduce the bananas to 2 to keep the texture balanced.

Healthier Swaps

Replace ½ the flour with whole wheat flour for added fiber. You can also swap the granulated sugar for coconut sugar—it has a lower glycemic index and a caramel-like flavor.

Boozy Banana Bread

Add 2 tbsp dark rum or bourbon to the wet ingredients for a grown-up twist. The alcohol bakes off, but it leaves a subtle depth of flavor. I like using Myers’s Rum for its rich molasses notes. 💫
