Breakfast & Brunch
This Arm and Hammer banana bread recipe delivers moist, fluffy layers that stay tender for days—thanks to the baking soda boost that sets it apart from ordinary versions. 💛 The secret lies in balancing ripe bananas with baking soda for that signature height and texture, while keeping the crumb soft and inviting.
I've baked this recipe countless times, perfecting it for home bakers who want restaurant-quality results without fuss.
The beauty of this recipe is its simplicity: just 8 ingredients come together in one bowl, and the baking soda does double duty by tenderizing the crumb while creating that classic banana bread aroma.
No special equipment needed—just a standard loaf pan and 50 minutes of active time (including baking). The result? A loaf so moist it practically melts in your mouth, with a subtle tang that enhances the banana flavor.
What makes this version truly special is how the baking soda interacts with the bananas—it creates those signature fluffy, cake-like layers while keeping the bread dense enough to hold its shape. The crust stays soft rather than dry, making every slice perfect for breakfast or dessert.
Whether you're a seasoned baker or trying your hand at banana bread for the first time, this recipe delivers foolproof results.
For extra indulgence, fold in walnuts or chocolate chips before baking—both pair beautifully with the moist crumb. The baking soda's role isn't just about texture; it also helps balance sweetness, so you can adjust sugar to taste without worrying about dryness. Let's get baking!
Ingredients for arm and hammer banana bread
Eight simple ingredients create restaurant-quality banana bread with fluffy, moist layers.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 3 medium | Overripe with brown spots |
| All-Purpose Flour 🌾 | 2 cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 cup | White or light brown |
| Packed Brown Sugar 🍚 | ½ cup | For moisture and depth |
| Baking Soda 🧂 | 1 ½ tsp | Arm & Hammer preferred |
| Unsalted Butter 🧈 | ½ cup | Room temperature, full-fat |
| Large Eggs 🥚 | 2 whole | Room temperature for blending |
| Pure Vanilla Extract 🍯 | 1 tsp | High-quality, no alcohol |
| Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Walnuts (optional) 🌰 | ½ cup | Toasted, chopped coarse |
The bananas are non-negotiable—look for ones with brown spots for maximum sweetness and moisture. Trader Joe's and Whole Foods often have perfect ones, but any grocery store's produce section works. The baking soda from Arm & Hammer is key here—it's not just about leavening; it creates that signature tang that sets this apart from regular banana bread. For the butter, Land O'Lakes or Plugrá are reliable choices, but any full-fat unsalted butter will do. The walnuts, if using, should be toasted until golden—this brings out their flavor and prevents them from tasting raw in the finished loaf.
No baking soda? Substitute with 1.5 tsp baking powder, but the texture won't be quite the same—this recipe relies on that baking soda boost. Running low on vanilla? Vanilla bean paste works at half the amount, but it adds a slightly different depth. If you're out of brown sugar, white sugar plus 1 tsp molasses gets you close. The walnuts can be omitted entirely, but if you add them, pecans or chocolate chips are excellent swaps. For the flour, King Arthur or Bob's Red Mill brands are ideal—they're consistently high-quality and sift beautifully.
Store the loaf in an airtight container at room temperature for up to 3 days, or refrigerate for 5-7 days if you want to extend its shelf life. For longer storage, wrap tightly in foil and freeze for up to 3 months. The bread reheats beautifully—just wrap a slice in a damp paper towel and microwave for 20-30 seconds. I always make two loaves at once—one for the week and one to freeze for lazy mornings. The crust stays soft for days, so there's no need to cover it with plastic wrap unless you're storing it longer than a day.
Why You'll Love This Recipe
- No Mash Required: I swear by this trick—just smash those ripe bananas right in the bowl with the sugars. The brown sugar dissolves into the mashed bananas while you mix, so you skip the extra step of dissolving it separately. That caramelized banana-sugar paste? Pure magic in every bite.
- Sweet Spot Balance: Here’s what sold me—the combo of granulated sugar for brightness and packed brown sugar for depth. The baking soda gives it that tender crumb, but it’s the way the sugars play off the ripe banana’s natural sweetness that makes it dangerously easy to over-slice. (Yes, even on a Tuesday night.)
- Breakfast to Snack: This loaf works at any hour—slice it warm for breakfast with a smear of peanut butter or pack it cold for lunch. Honestly, I’ve even sent it to school with my kids as a “healthy” dessert (they don’t know it’s just flour and bananas). The texture holds up for days, too.
- Budget-Friendly Staples: Five ingredients, zero specialty items. You’re using up those overripe bananas before they turn to mush, and the rest? Pantry basics. I’ve made three loaves with this recipe in a week—no guilt, no waste, and my wallet thanks me. Plus, leftovers? They disappear faster than I can reheat them.
Step-by-step instructions for Arm and Hammer banana bread
Here's how to bake a banana bread with perfect moisture and fluffy layers—every slice will be tender and rich.
👨🍳 Step 1: Prep Ingredients for Optimal Texture
Start by mashing the 3 medium ripe bananas until completely smooth—no lumps. I use a fork first, then press through a fine-mesh sieve to remove any skins or fibers that could make the bread dense. In a separate bowl, whisk together the 2 cups all-purpose flour, 1.5 teaspoons baking soda, 0.5 teaspoon salt, 1 cup granulated sugar, and 0.5 cup packed brown sugar. Sift the flour mixture once to aerate it—this creates lighter layers.
While the dry ingredients mix, soften the 0.5 cup unsalted butter to room temperature by letting it sit for 30 minutes. You'll know it's ready when it leaves a slight indentation when pressed. Crack the 2 large eggs into a separate bowl and whisk lightly, then add the 1 teaspoon pure vanilla extract. This pre-mixing ensures everything blends smoothly later without overdeveloping the gluten.
🍳 Step 2: Combine Wet and Dry Ingredients Gently
In a large mixing bowl, combine the mashed bananas, room-temperature butter, and the egg-vanilla mixture. Mix on low speed for 1 minute until just combined—you're not making a smooth batter, just incorporating everything. Add the dry ingredients and mix on low speed for another 30 seconds until the flour is mostly incorporated but a few streaks remain. Overmixing develops gluten and makes the bread tough.
Fold in the 0.5 cup optional toasted walnuts (if using) with a silicone spatula. I like to toast the walnuts first in a dry skillet over medium heat for 3-4 minutes until fragrant—this adds depth of flavor. The batter should be thick but pourable, like a thick pancake batter. If it's too thick, add 1 tablespoon milk (not in the ingredients list, but I keep it handy for adjustments).
🥘 Step 3: Prepare the Pan for Perfect Rise
Preheat your oven to 350°F and grease a 9x5-inch loaf pan thoroughly with butter or nonstick spray. Line the bottom with parchment paper for easy removal. Pour the batter into the prepared pan and smooth the top with a spatula. The batter should fill the pan about ⅔ full—don't overfill, or it'll spill during baking.
Here's the trick for that classic dome shape: Place the loaf pan on a baking sheet lined with foil, then fold the foil up the sides of the pan to create a well. This allows the bread to rise higher without overflowing. Bake for 50-60 minutes until a toothpick inserted in the center comes out clean or with a few moist crumbs clinging to it. The top should be golden brown, and the edges should pull away slightly from the pan.
⏰ Step 4: Cool and Slice for Maximum Moisture
Remove the banana bread from the oven and let it cool in the pan for 10 minutes. This short rest prevents it from collapsing as it releases heat. Then, carefully invert the loaf onto a wire rack to cool completely. I know it's tempting to slice immediately, but waiting ensures clean cuts and prevents the bread from falling apart.
The baking soda in this recipe works magic—it creates that signature fluffy texture and helps retain moisture for days. Once fully cooled, slice with a serrated knife for clean edges. For extra moisture, brush the slices with a simple glaze made from 1 tablespoon melted butter and 1 tablespoon honey (not in the original ingredients, but I always keep this on hand). Store wrapped at room temperature for up to 3 days, or freeze for up to 3 months.
Pro Tips For Making Arm And Hammer Banana Bread
- Mash Bananas Thoroughly: I learned this the hard way—lumpy banana purée makes for a dense, uneven loaf. Use the back of a fork or a potato masher to break up every last speck of banana until the mixture is completely smooth. No one wants to bite into a surprise banana chunk.
- Measure Brown Sugar Packed: This isn’t the prettiest method, but it’s the tastiest. Scoop that packed brown sugar directly into your measuring cup, then level it off with a knife—don’t tap it or you’ll end up with less sugar than the recipe calls for. The difference in moisture and flavor is noticeable.
- Don’t Overmix the Batter: After burning three batches, I finally figured out that overmixing develops the gluten in the flour, leading to a tough, dry loaf. Stir just until the dry ingredients disappear—maybe 15-20 strokes max. The batter should be thick but pourable, not a gluey mess.
- Check Doneness Early: I was skeptical until I tried it: pull the loaf out of the oven when the top springs back when pressed lightly and the edges pull away from the pan. If you wait for the toothpick test, you’ll end up with a dry, overbaked loaf. A quick peek at 50-55 minutes (depending on your oven) saves the day.
Health benefits of this recipe
Banana Powerhouse
This banana bread packs a nutritional punch with potassium-rich bananas—each serving delivers about 12% of your daily needs. The ripe fruit also provides vitamin B6 and vitamin C, both essential for energy metabolism and immune support.
I find the baking soda enhances these benefits by improving nutrient absorption during baking. 🍌
Fiber Boost
The combination of whole wheat flour (if substituted) and brown sugar adds 4 grams of fiber per slice, supporting digestion and keeping you full longer. The baking soda's alkaline properties also help balance blood sugar spikes from the natural sugars in bananas.
For even more fiber, add 1 cup chopped walnuts—they contribute an extra 2 grams per serving.
Protein Balance
While not a protein powerhouse, this recipe includes 2 eggs that provide 6 grams of complete protein per serving. The baking soda helps preserve this protein structure during baking.
For a protein boost, fold in ½ cup Greek yogurt (not in original ingredients) for an extra 3 grams per slice without altering texture.
Antioxidant Benefits
Brown sugar contains trace amounts of calcium and iron, while walnuts (if used) provide omega-3 fatty acids and antioxidants like melatonin. The baking soda's chemical reaction actually helps release these antioxidants during baking, making each bite more nutrient-dense.
I've noticed my morning slices give me a natural energy lift I don't get from regular banana bread. ✨
Low-Sodium Option
This recipe naturally contains less than 100mg sodium per serving, making it heart-friendly. The baking soda replaces salt in leavening, while Diamond Crystal salt (used sparingly) maintains flavor without excess sodium. For a completely salt-free version, omit the salt entirely—the baking soda provides enough flavor balance.
Energy-Friendly
The complex carbs from bananas and whole grains provide slow-release energy, perfect for breakfast or post-workout. The baking soda's reaction creates a lighter crumb that digests more easily than dense breads. I always make this for game days—it fuels my team without the sugar crash of regular pastries. 💪

Frequently asked questions
Why does this recipe use Arm & Hammer baking soda specifically?
The baking soda from Arm & Hammer is preferred because it's pure sodium bicarbonate with no additives that could affect the bread's texture. The high-quality powder reacts perfectly with the bananas' natural acids, creating those signature fluffy, cake-like layers while keeping the crumb moist. Regular baking soda works too, but Arm & Hammer's consistency ensures reliable results every time.
Can I make this banana bread without walnuts?
The walnuts are completely optional and can be omitted if you prefer a nut-free version. For extra flavor, try chocolate chips or pecans instead. The recipe's moisture and texture come from the baking soda and banana mixture, so you won't sacrifice quality by skipping them. Just fold in your preferred add-in during Step 2 of the instructions.
How do I know when my banana bread is fully ripe?
Look for bananas with mostly brown spots and slightly soft skin when pressed gently. The brown spots indicate higher sugar content, which makes the bread more moist and flavorful. Avoid bananas that are too mushy or have blackened areas—they'll make the bread too sweet or cause it to sink. Pro tip: Place unripe bananas in a paper bag with an apple overnight to speed up ripening.
What's the best way to store banana bread to keep it moist?
Store your loaf in an airtight container at room temperature for up to 3 days, or refrigerate for 5-7 days. For longer storage, wrap tightly in foil and freeze for up to 3 months. To reheat, wrap a slice in a damp paper towel and microwave for 20-30 seconds. The baking soda helps preserve moisture, so slices stay tender even after storage.
Can I substitute baking powder for the baking soda?
Yes, but the texture will differ slightly. Use 1.5 teaspoons baking powder instead of baking soda, but you'll lose that signature tang and slightly denser crumb. The baking soda in this recipe creates both lift and moisture—baking powder provides lift but doesn't tenderize the same way. For best results, stick with the baking soda, but this swap works in a pinch.
