Martha Stewart Banana Bread Recipe: Moist Loaf with Walnut Crunch

This banana bread delivers the moist, tender crumb and perfect balance of sweetness you expect from a classic recipe. The addition of walnuts provides a satisfying crunch that complements the soft texture.

With simple ingredients and straightforward instructions, this proven method ensures professional results every time. The loaf bakes up golden brown with a crackly top that gives way to an irresistibly moist interior.

Ingredients for Martha Stewart Banana Bread

Simple pantry staples and ripe bananas create this classic loaf with signature texture and flavor.

The bananas are critical—use ones with plenty of brown speckles (the starch has fully converted to sugar). Whole Foods or Trader Joe’s often have perfect overripe bunches marked down. For the flour, King Arthur is the gold standard for consistent results. Unsalted butter allows you to control the salt content precisely. Always check your baking soda’s freshness—if it doesn’t bubble when mixed with vinegar, replace it.

No sour cream? Full-fat Greek yogurt works at a 1:1 ratio. Out of walnuts? Pecans or almonds offer similar texture. For a nut-free version, add an extra half-cup of chocolate chips (they’ll provide moisture and richness). The cinnamon can be omitted if you prefer a plainer flavor, but it adds warmth that complements the bananas beautifully.

Store the loaf wrapped in plastic at room temperature for up to 3 days. For longer storage, refrigerate for up to 1 week or freeze slices for 3 months. Slice before freezing for easy single-serving portions (just toast straight from the freezer).

Step-by-Step Instructions for Banana Bread

Master the technique for a perfectly moist loaf with these professional steps.

Step 1: Prepare and Mix Dry Ingredients

Begin by preheating your oven to 350°F. In a medium bowl, whisk together the 1.5 cups All-Purpose Flour, 1 tsp Baking Soda, 0.5 tsp Salt, and 1 tsp Ground Cinnamon until uniformly combined. Sifting the flour first ensures a lighter texture, which is crucial for the final crumb structure.

This dry mixture creates the foundation for your bread’s structure. The cinnamon adds warmth, while the baking soda guarantees proper rise. Set this aside while you prepare the wet ingredients—keeping them separate until the last moment prevents premature gluten development.

Step 2: Cream Butter and Sugars, Then Incorporate Wet Ingredients

In a large bowl, use an electric mixer to cream the 0.5 cup Unsalted Butter and 0.75 cup Granulated Sugar on medium speed for 2-3 minutes, until the mixture is light and fluffy. This step aerates the butter, which contributes to the bread’s tender texture.

Add the 2 whole Large Eggs one at a time, mixing well after each addition. Stir in the 1 tsp Vanilla Extract, then the 3 whole Ripe Bananas, mashing them slightly as you go. The bananas should be heavily speckled for optimal sweetness and moisture. Finally, fold in the 0.5 cup Sour Cream, which ensures the loaf stays rich and moist.

Step 3: Combine Wet and Dry Ingredients

Gradually add the dry ingredient mixture to the wet ingredients, folding gently with a spatula just until combined. Overmixing will result in a dense loaf, so stop as soon as you no longer see streaks of flour. The batter will be thick but still pourable.

Fold in the 1 cup Chopped Walnuts at this stage, ensuring even distribution throughout the batter. The walnuts add a satisfying crunch and contrast to the soft, moist crumb. If you prefer a toasted flavor, ensure the walnuts are toasted before adding them to the mix.

Step 4: Bake to Golden Perfection

Pour the batter into a greased 9×5-inch loaf pan, smoothing the top with your spatula. Bake in the preheated oven for 55-65 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs attached.

The bread is done when the top is golden brown and the edges begin to pull away from the sides of the pan. If the top browns too quickly, tent the pan with aluminum foil to prevent over-browning while the center finishes cooking.

Step 5: Cool and Serve

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, making it easier to remove without crumbling. After 10 minutes, transfer the bread to a wire rack to cool completely.

Slice only after the bread has cooled for at least 30 minutes to ensure clean cuts and optimal texture. Serve at room temperature for the best flavor and moisture. Store any leftovers wrapped tightly in plastic wrap at room temperature for up to 2 days.

Pro Cooking Tips for martha stewart banana bread

Banana Ripeness Matters

I always use bananas with deep brown speckles covering at least 80% of the peel. The starch has fully converted to sugar at this stage, giving you maximum sweetness and moisture. If your bananas aren’t ripe enough, roast them at 300°F for 15-20 minutes to intensify their flavor. 🌟

Room Temperature Ingredients

Take your eggs and butter out of the fridge 30-60 minutes before starting. Room temperature ingredients emulsify better, creating a smoother batter and more even texture in your final loaf. I’ve found this makes a noticeable difference in crumb consistency.

Mixing Technique

When combining wet and dry ingredients, use a spatula and fold just until the flour disappears. Overmixing develops gluten, which can make your bread dense. The batter should look slightly lumpy—that’s perfect. I count 10-12 folds as my maximum before stopping.

Pan Preparation

Grease your 9×5-inch loaf pan thoroughly with butter or nonstick spray, then dust with a light coating of flour. This creates a reliable release. For extra insurance, I line the bottom with parchment paper, leaving an overhang on the long sides for easy removal.

Doneness Test

Start checking for doneness at the 55-minute mark. Insert a toothpick into the center—it should come out clean or with just a few moist crumbs. If the top browns too quickly, tent with foil. The internal temperature should reach 200-205°F when fully baked. 💡

Cooling Patience

Let the bread cool in the pan for exactly 10 minutes, then transfer to a wire rack. Slicing too soon causes crumbling. I wait a full 2 hours before cutting to ensure the structure sets completely and the flavors meld beautifully.
