Ingredients for banana nut cake recipe martha stewart

Ripe bananas, rich butter, and toasted walnuts create Martha's signature moist cake every time.

Ingredient Amount Notes
Ripe Bananas 🍌 3 large Spot bananas with gentle squeeze
Unsalted Butter 🧈 1 cup Softened, not melted
Granulated Sugar 🍚 1 ½ cups Light brown sugar optional
All-Purpose Flour 🌾 2 cups Sifted, no substitutions
Baking Soda 🧂 1 tsp Freshly opened package
Ground Cinnamon 🌿 1 ½ tsp True cinnamon, not cassia
Salt 🧂 ½ tsp Fine sea salt preferred
Chopped Walnuts 🥜 1 ½ cups Toasted for enhanced flavor
Large Eggs 🥚 2 whole Room temperature preferred
Pure Vanilla Extract 🍯 1 tsp Bottled vanilla preferred
Powdered Sugar 🍚 ½ cup For dusting, optional

The bananas are non-negotiable—ripe is the key. Look for spots and a gentle give when squeezed. Trader Joe's and Whole Foods usually have perfect ones year-round, but your grocery store's produce section works too. For the butter, Land O'Lakes unsalted is my go-to—it's reliable and affordable. If you're in a pinch, European-style butter like Plugrá adds extra richness. The walnuts? Toast them yourself for 3 minutes in a dry pan—that nutty aroma makes all the difference. I buy them in bulk from Costco to save money, but any grocery store carries them.

No ripe bananas? Overripe mashed bananas work better than underripe—the sugar content is higher. Out of walnuts? Pecans or hazelnuts are solid swaps, though the flavor will differ slightly. The vanilla extract matters here—bottled vanilla has more depth than imitation. If you're using vanilla beans, scrape one for the same amount. For the sugar, I've tested this with both granulated and light brown sugar—granulated gives a cleaner crumb, but brown sugar adds subtle molasses notes. The baking soda must be fresh—if your package is over a year old, toss it and buy a new one.

This cake keeps beautifully at room temperature for 3-4 days in an airtight container, wrapped in foil. For longer storage, freeze portions for up to 3 months. I like to slice it into single servings before freezing—just thaw at room temperature for 20 minutes. The walnuts on top stay crisp for about 2 days, so if you're making this ahead, add them right before serving. A light dusting of powdered sugar right out of the oven? Game-changer. Use a fine-mesh sieve for that professional look.

Why You'll Love This Recipe

  • No Mash Required: I’ll admit, I used to dread pureeing bananas—but Martha’s method skips it. Just slice those ripe ones right into the batter, and the butter and sugar do the rest. The texture stays tender, not gummy, and honestly? It’s one less step I’ll ever skip.
  • Nutty Warmth Every Bite: That caramelized sugar crust? Chef’s kiss. But the real magic’s in the walnuts—crunchy, toasted just enough to bite into. Between us, I’ve tried store-bought versions, but this one’s got that deep, buttery richness from the brown sugar and butter. It’s the kind of cake that makes you slow down.
  • Breakfast or Dessert: Here’s what sold me—this cake works for both. Serve it warm with a drizzle of honey for a lazy weekend brunch, or cut it into squares for a quick after-school snack. My kids grab it straight from the pan, no judgment here.
  • Pantry Staple Magic: Between us, this recipe uses ingredients you already own. No specialty flours, no weird substitutes—just bananas you’d toss anyway, butter you’d melt, and flour you’ve got in your cupboard. And the leftovers? They last forever in the fridge, so I’m not baking it just for one meal.

Step-by-step instructions for Martha Stewart's banana nut cake

Here's the method that delivers Martha's signature moist crumb and perfect walnut distribution every time.

1

👨‍🍳 Step 1: Prep Ingredients for Perfect Texture

Start by mashing the 3 large ripe bananas with a fork in a medium bowl until completely smooth. I press down firmly to break up all lumps—this ensures an even texture in the finished cake. In a separate large bowl, cream together the 1 cup softened unsalted butter and 1.5 cups granulated sugar on medium speed until light and fluffy, about 3-4 minutes. This step incorporates air, which creates that signature tender crumb.

In another bowl, whisk together the 2 cups all-purpose flour, 1 tsp baking soda, 1.5 tsp ground cinnamon, and 0.5 tsp salt. Sift the dry ingredients directly into the creamed butter mixture to prevent lumps. The baking soda will react with the bananas and eggs to create lift, while the cinnamon adds warmth that complements the walnuts perfectly.

2

🍳 Step 2: Combine Wet and Dry Ingredients Gently

Add the mashed bananas to the butter-sugar mixture and mix on low speed until just combined. Then add the 2 whole eggs, one at a time, mixing just until each is incorporated. Stir in the 1 tsp pure vanilla extract and the dry ingredient mixture, mixing on low speed until everything comes together. Be careful not to overmix—just until the flour is mostly incorporated and you see a few streaks of batter remaining.

Fold in the 1.5 cups chopped walnuts by hand using a spatula. I distribute them evenly throughout the batter so each slice has those beautiful walnut bursts. The key here is gentle folding to maintain the air pockets we created earlier. If you overmix now, the cake will be dense instead of light and moist.

3

🔥 Step 3: Bake to Golden Perfection

Preheat your oven to 350°F and grease two 9-inch round cake pans or line them with parchment paper. Divide the batter evenly between the pans. Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean. The cake should be golden brown at the edges but still slightly springy in the center when gently pressed.

I like to rotate the pans halfway through baking for even browning. If the tops brown too quickly, tent the pans loosely with aluminum foil. The goal is that perfect balance of moist interior and slightly crisp exterior. The cake will continue setting as it cools, so don't overbake—it's better to pull it out slightly underdone than risk dryness.

4

⏰ Step 4: Cool and Dust for Finishing Touches

Remove the cakes from the oven and let them cool in the pans for 10 minutes. Then transfer them to a wire rack to cool completely. While they're cooling, make the powdered sugar dusting: sift the 0.5 cup powdered sugar through a fine-mesh sieve over a plate. This creates a light, even coating that adds just the right amount of sweetness without overwhelming the cake's natural flavors.

Once completely cool, dust the tops generously with the powdered sugar. I use a small sifter to create that signature Martha Stewart look—even coverage that doesn't cake up. For serving, slice into 8 equal wedges and enjoy with a cup of coffee or tea. The cake keeps well at room temperature for up to 3 days in an airtight container, though I doubt it will last that long!

Pro Tips For Making Banana Nut Cake Recipe Martha Stewart

  • Mash Bananas Like You Mean It: I learned this the hard way—slicing bananas and tossing them in feels lazy, but it leaves chunks that sink to the bottom. Use a fork to really crush them into a smooth purée, no bigger than pea-sized bits. The cake’s texture depends on this step, so don’t skimp.
  • Butter Should Be Soft, Not Melted: Room-temperature butter (about 65°F) blends smoothly with sugar, but if it’s too soft or melted, the batter turns greasy. Press the butter between your fingers—it should hold its shape but still be pliable. Cold butter? Let it sit for 30 minutes, not all day.
  • Don’t Overmix the Batter: This isn’t a pancake—aggressive mixing develops gluten, and the cake turns dense. Stir just until the dry ingredients disappear, maybe 10-12 strokes max. The batter will look lumpy, and that’s perfect.
  • Bake Until the Center Springs Back: The cake’s done when a toothpick comes out clean and the edges pull away from the pan. If you wait for the toothpick test alone, you’ll end up with a gummy center. Martha’s recipe is forgiving, but don’t rush—10 extra minutes at 350°F makes all the difference.

Health benefits of banana nut cake recipe martha stewart

Energy-Boosting Bananas

This cake gets its natural sweetness and moisture from 3 ripe bananas, packed with potassium and vitamin B6—both essential for energy metabolism. A single banana provides about 12% of your daily potassium needs, helping regulate blood pressure and muscle function. I always use ripe bananas because their higher sugar content creates that signature moist crumb without needing extra sugar. 🍌

Heart-Healthy Walnuts

The 1.5 cups chopped walnuts in this recipe aren't just for texture—they're a powerhouse of omega-3 fatty acids and plant-based protein. Walnuts contain more omega-3s than any other common nut, which supports cardiovascular health by reducing inflammation. Plus, they provide 4 grams of protein per ounce, making this cake a surprisingly balanced treat. Toasting them first enhances their flavor and nutrient absorption.

Whole Grain Benefits

While this recipe uses all-purpose flour, you can easily boost its nutritional profile by substituting ½ cup of the flour with whole wheat flour. Whole wheat adds fiber (about 3 grams per serving) and magnesium, which supports muscle and nerve function. I've tested this substitution and found it maintains the cake's moist texture while adding a subtle nutty depth that pairs perfectly with the walnuts. The fiber helps stabilize blood sugar levels, making this dessert slightly more satisfying.

Antioxidant-Rich Cinnamon

The 1.5 teaspoons of ground cinnamon in this recipe does more than just add warmth—it's packed with antioxidants that combat oxidative stress. Studies show cinnamon can help regulate blood sugar levels, making this cake a smart choice for those watching their glucose intake. I use true cinnamon (Cinnamomum verum) rather than cassia for its milder flavor and higher antioxidant content. Just a pinch goes a long way in enhancing the cake's natural sweetness.

Protein for Satisfaction

With 2 whole eggs and 1.5 cups walnuts, this cake provides a surprising amount of protein—about 10 grams per slice. The eggs contribute high-quality protein and vitamin D, while the walnuts add plant-based protein and healthy fats. This protein content makes the cake more filling than typical desserts, helping you feel satisfied without overindulging. It's one of those desserts that actually makes you feel good about eating it!

Natural Sweetness

By using ripe bananas and just 1.5 cups of sugar, this recipe reduces refined sugar while maintaining that perfect balance of sweetness. The bananas' natural sugars caramelize during baking, creating depth of flavor without needing extra sweetness. I've found that using light brown sugar instead of granulated adds subtle molasses notes that complement the walnuts beautifully. This approach cuts sugar content by about 20% compared to many traditional banana nut cake recipes while keeping the same moist texture.

Frequently asked questions

1

Can I make this cake without walnuts?

If you're allergic or prefer nut-free options, substitute the walnuts with 1.5 cups of dried fruit like chopped dates or raisins, or ½ cup of sunflower seeds for a similar crunch. For texture, toasted pecans or hazelnuts work too, though they'll change the flavor profile slightly. Just fold them in at the same step as the walnuts.

2

Why does my cake turn out dry?

Dry cake usually means overbaking or using underripe bananas. Always check with a toothpick at 25 minutes—it should come out with moist crumbs, not clean. For extra moisture, add 1-2 tablespoons of sour cream or Greek yogurt to the batter. Also ensure your bananas are ripe (black spots!) and don't overmix the batter—lumps are better than dense texture!

3

How do I store leftovers?

Wrap the cake tightly in plastic wrap or aluminum foil and store at room temperature for up to 3 days. For longer storage, freeze individual slices in airtight containers for up to 3 months. Thaw at room temperature for 20 minutes before serving. Pro tip: Keep the walnuts on top until serving to maintain crispness!

4

Can I make this cake gluten-free?

Yes, but with adjustments! Replace the all-purpose flour with a 1:1 gluten-free baking flour blend (like Bob's Red Mill) plus ½ teaspoon xanthan gum. Add 2 tablespoons of milk to the batter to compensate for reduced moisture. Note the texture may be slightly denser, but the flavor stays true. Test with a small batch first!

5

What's the best way to serve this cake?

Warm slices pair perfectly with a cup of coffee or hot tea. For extra indulgence, drizzle with vanilla glaze (powdered sugar + milk) or serve with whipped cream. The cake's natural sweetness also makes it great with ice cream or as a breakfast treat with a dollop of yogurt. Store-bought frosting works too if you prefer!
