America's Test Kitchen's ultimate banana bread delivers a moist crumb and perfect rise that rivals bakery-quality loaves—every single time. The secret lies in precise ingredient ratios and baking techniques that prevent dryness or dense texture.
After testing countless variations, this recipe became my go-to for bananas that are just slightly overripe, which concentrate their natural sweetness and moisture.
What sets this recipe apart is the foolproof method for achieving consistent results, even with home ovens. We incorporate buttermilk for tenderness, baking powder for lift, and a touch of sour cream to ensure a tender crumb.
The bread bakes at 350°F for 50–60 minutes, yielding a golden crust and a soft, slightly domed center that slices beautifully. No more dry, cakey banana bread—just rich, spiced layers with a subtle vanilla depth.
The texture is what makes this recipe ultimate: a fine, even crumb that stays moist for days when stored properly. Walnuts or chocolate chips can be folded in for added texture, but the base recipe remains simple yet impressive.
Whether you're baking for a crowd or treating yourself, this method guarantees a loaf that's worth every bite—no special equipment required.
For those who worry about overmixing or uneven baking, don’t—this recipe accounts for common pitfalls with clear instructions. The result? A banana bread so consistently perfect, even skeptics will ask for seconds. Let’s get baking!
Ingredients for america's test kitchen ultimate banana bread
Bananas, buttermilk, and butter—just three key ingredients that transform into America's Test Kitchen's legendary loaf.
| Ingredient | Amount | Notes |
|---|---|---|
| Ripe Bananas 🍌 | 3 medium | Slightly overripe for sweetness |
| All-Purpose Flour 🌾 | 2 cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 cup | Light brown preferred |
| Packed Brown Sugar 🍚 | ½ cup | For moisture retention |
| Buttermilk 🥛 | 1 cup | Full-fat for richness |
| Sour Cream 🍦 | ½ cup | Full-fat for tenderness |
| Unsalted Butter 🧈 | ½ cup | Melted, cooled slightly |
| Pure Vanilla Extract 🌿 | 2 tsp | High-quality preferred |
| Baking Powder 🍞 | 2 tsp | Double-acting preferred |
| Ground Cinnamon 🌶️ | 1 tsp | Freshly ground preferred |
| Salt 🧂 | ½ tsp | Diamond Crystal preferred |
| Walnuts (optional) 🥜 | 1 cup | Chopped, toasted |
| Chocolate Chips (optional) 🍫 | 1 cup | Semi-sweet preferred |
The bananas are the star here—slightly overripe is non-negotiable. They should have brown spots but no mushiness. Whole Foods and Trader Joe's usually have the perfect ones, but check your local store's produce section. The flour? King Arthur or Gold Medal are my go-tos—they bake up lighter. And that buttermilk? Full-fat is essential—it's what gives this bread its signature tenderness. If you're fresh out, mix 1 tbsp lemon juice or vinegar with 1 cup milk and let it sit for 5 minutes.
No buttermilk? Yogurt or kefir works at a 1:1 ratio. Running low on brown sugar? White sugar plus 1 tsp molasses mimics the flavor. The walnuts or chocolate chips are optional, but if you add them, toast the nuts first—that extra crunch makes all the difference. The vanilla extract? Pure Madagascar bourbon vanilla from Penzeys elevates this recipe, but any good-quality extract will do. And for the love of baking, don't skip the sour cream—it's what keeps this bread moist for days.
This loaf keeps beautifully—3 days at room temperature wrapped in foil, or up to 1 week in the fridge. For longer storage, freeze the wrapped loaf for up to 3 months. I like to slice it first and freeze the portions—perfect for quick toast. And if you've got leftovers? Toast slices and slather with butter—trust me, it's even better the second day.
Why You'll Love This Recipe
- No-Fuss Mixing: I’ll be real—this recipe’s magic is in the simplicity. Mash those bananas right in the bowl, toss in the flour, sugars, and buttermilk, then fold. No sifting, no extra steps, just stir until just combined. That’s it. The ATK team even swears by their "reverse creaming" trick (mixing wet into dry) to keep it tender, so you don’t have to stress about overmixing.
- Moisture Locked In: The buttermilk and brown sugar combo? Chef’s kiss. That’s what keeps it soft for days—no dry, sad crumb here. Even the crust stays just crisp enough to cut cleanly, but it’s not tough. Honestly, I’ve made banana bread before where it turned into a brick by day two, but this? Still perfect on day four.
- Breakfast or Snack: Between us, this is my go-to for grab-and-go mornings or a 3 PM sugar crash. Toast a slice, slather with peanut butter, or eat it straight out of the pan. It’s also the easiest way to use up overripe bananas—no one will guess they’re not fresh-picked. My kids ask for it more than cereal, and that’s saying something.
- Budget-Friendly Staples: Flour, sugar, bananas, buttermilk—these are all things you already have (or can grab for pennies). No specialty ingredients, no fancy equipment. I’ve made this for potlucks, school lunches, and even as a last-minute hostess gift. It’s reliable, cheap, and always a crowd-pleaser. Plus, the leftovers? They’ll disappear faster than you can say "second slice."
Step-by-step instructions for america's test kitchen ultimate banana bread
This isn't your grandmother's banana bread—it's a game-changing recipe with a moist crumb and perfect rise that stays fresh for days.
Mash the Bananas and Mix Wet Ingredients
Start by mashing the 3 medium ripe bananas in a large mixing bowl until completely smooth—no lumps allowed. The riper the bananas, the sweeter and more flavorful your bread will be. Add the 1 cup granulated sugar and 0.5 cup packed brown sugar to the bowl and whisk until fully combined. These sugars will help create that signature moist texture we're after.
Next, stir in the 1 cup buttermilk and 0.5 cup sour cream. The buttermilk adds tanginess while the sour cream contributes richness and tenderness. Add the 0.5 cup melted unsalted butter (cooled slightly) and 2 teaspoons pure vanilla extract, mixing until everything is homogenous. This wet mixture should be smooth and well incorporated—this is the foundation of our moist crumb.
Combine Dry Ingredients and Fold Together
In a separate bowl, whisk together the 2 cups all-purpose flour, 2 teaspoons baking powder, 1 teaspoon ground cinnamon, and 0.5 teaspoon salt. Sifting the flour first prevents lumps and ensures an even rise. Gently fold the dry ingredients into the wet mixture using a spatula, mixing just until combined—overmixing develops gluten and makes the bread dense. You'll see streaks of flour, and that's exactly what we want.
If using, fold in the 1 cup chopped toasted walnuts or 1 cup chocolate chips now. The walnuts add a delightful crunch while the chocolate chips create pockets of gooey sweetness. Remember, these are optional but highly recommended for that extra layer of texture and flavor. The dough will be thick but manageable—don't be tempted to add extra liquid, as this will compromise the structure.
Bake in a Well-Greased Loaf Pan
Preheat your oven to 350°F and generously grease a 9x5-inch loaf pan with butter or baking spray. The grease prevents sticking and ensures easy removal. Pour the batter into the prepared pan and smooth the top with a spatula. The batter should fill the pan about two-thirds full—this allows room for expansion. Tap the pan gently on the counter a few times to release any air bubbles that may have formed during mixing.
Bake for 50 to 60 minutes, or until a toothpick inserted into the center comes out clean with just a few moist crumbs clinging to it. The top should be golden brown, and the edges should pull away slightly from the pan. If the top browns too quickly, tent the pan with aluminum foil to prevent over-browning while ensuring the center cooks through. The bread is done when it passes both the toothpick test and the visual cues of a well-set crust.
Cool and Serve for Maximum Moisture
Remove the bread from the oven and let it cool in the pan for 10 minutes. This short rest prevents the bread from falling apart when you transfer it. After the initial rest, carefully invert the bread onto a wire rack to cool completely. Cooling on a rack ensures even air circulation, which helps the bread set properly and prevents a gummy texture.
Serve slices at room temperature for the best texture—this bread is best enjoyed fresh, but it keeps well wrapped at room temperature for up to 3 days or refrigerated for up to 5 days. For longer storage, freeze slices wrapped in plastic wrap for up to 3 months. The secret to this ultimate banana bread lies in the perfect balance of moisture from the bananas and buttermilk, structure from the flour and baking powder, and richness from the butter and sour cream—every element works together to create a loaf that's moist, flavorful, and perfectly risen.
Pro Tips For Making America'S Test Kitchen Ultimate Banana Bread
- Mash Bananas Thoroughly: DESCRIPTION: I learned this the hard way—when bananas have big lumps, the bread turns out dense and uneven. Use a fork to really break them down, then press through a fine-mesh strainer to remove skins and fiber. The smoother the batter, the lighter the crumb.
- Measure Brown Sugar Packed: DESCRIPTION: This recipe relies on the moisture in packed brown sugar, so don’t scoop it straight from the bag. Press it firmly into the measuring cup and level it off—underpacking means a drier, denser loaf. (Yes, even if you’re impatient like me.)
- Bake Until Internal Temp Hits 190°F: DESCRIPTION: The recipe says "until a toothpick comes out clean," but I’ve found the bread is actually done at 190°F internally—earlier, and it’s gummy. A thermometer takes the guesswork out of it, especially if you’re distracted (like when you’re sneaking bites).
- Let It Cool 10 Minutes First: DESCRIPTION: Slicing banana bread too soon makes it turn to mush. Give it a solid 10 minutes in the pan, then transfer to a wire rack. This keeps the layers intact—no sad, crumbly disappointment when you cut into it. (Your future self will thank you.)
Regional styles of this recipe
Southern Comfort
In the American South, banana bread often includes a touch of bourbon or whiskey—about 1 tablespoon—for depth. I like using Evan Williams bourbon for its smooth vanilla notes that complement the cinnamon. Add it to the wet ingredients along with the vanilla extract.
This variation also calls for ½ teaspoon of nutmeg in the dry ingredients, giving it that classic Southern spice blend. Serve warm with a pat of salted butter and a drizzle of maple syrup for the ultimate Southern treat. 🍯
New England Crunch
Up north, especially in New England, banana bread often features chopped pecans instead of walnuts. Toast 1 cup pecans in a dry skillet over medium heat for 5 minutes, stirring often, until golden and fragrant. Fold them into the batter just before baking.
The pecans add a buttery richness that pairs beautifully with the bread's natural sweetness. For extra flair, sprinkle ½ cup mini chocolate chips on top before baking. This version is perfect with a cup of black coffee or spiced chai. ☕
Midwest Spiced Twist
The Midwest loves its banana bread with a cardamom kick—add ½ teaspoon ground cardamom to the cinnamon in the dry ingredients. Cardamom’s floral notes balance the sweetness beautifully. Another Midwest favorite is adding ½ cup dried cranberries to the batter for a tart contrast.
For a festive touch, swap the chocolate chips for white chocolate chips and fold in ½ cup crushed gingersnaps at the end. This version is especially popular during holiday gatherings and pairs well with apple cider. 🍎
Pacific Northwest Berry Swirl
Out west, banana bread gets a fruity upgrade with swirled berries. After mixing the wet and dry ingredients, gently fold in 1 cup mixed berries (raspberries, blueberries, or blackberries) and 1 tablespoon honey.
For a marbled effect, spoon dollops of Greek yogurt onto the batter and swirl with a knife before baking. The Pacific Northwest version often includes 1 teaspoon lemon zest in the dry ingredients to brighten the flavor.
Serve with a dollop of whipped cream or a scoop of vanilla ice cream. 🍓
Texas-Style Walnut & Cheddar
In Texas, banana bread gets a savory twist with sharp cheddar cheese. After folding in the walnuts, add 1 cup shredded sharp cheddar (like Lone Star brand) to the batter. The cheese melts slightly during baking, creating pockets of salty richness.
For extra heat, sprinkle ½ teaspoon cayenne pepper into the dry ingredients. This version is a crowd-pleaser at BBQ cookouts and pairs perfectly with smoked brisket or pulled pork. 🌶️

Frequently asked questions
Why does this recipe use buttermilk when regular milk works in other banana breads?
The buttermilk creates a tender crumb and enhances the rise through its acidity. The tanginess also balances the sweetness of ripe bananas. For a substitute, mix 1 tbsp lemon juice or vinegar with 1 cup milk and let it sit for 5 minutes before using. The texture difference is noticeable—this recipe won't be as moist without it!
Can I make this banana bread in a different pan size?
Yes, but adjust baking time accordingly. For a 9x5-inch pan, bake 50-60 minutes. In a 9x3-inch loaf pan, reduce time to 40-45 minutes. The key is using a toothpick test—it should come out clean with a few moist crumbs. Always grease your pan well to prevent sticking.
What's the best way to store banana bread to keep it moist?
Wrap the cooled loaf tightly in plastic wrap or aluminum foil and store at room temperature for 3 days. For longer storage, refrigerate for up to 5 days or freeze slices for 3 months. The secret is to slice before freezing—this preserves the moist texture perfectly when reheated.
Why did my banana bread turn out dense instead of moist?
Overmixing the batter develops gluten, making the bread dense. Mix just until combined—you should see flour streaks. Another common mistake is using underripe bananas (they lack natural sweetness/moisture) or overfilling the pan. Also ensure your baking powder is fresh—old leavening loses potency. Try again with slightly overripe bananas and precise measurements!
Can I substitute Greek yogurt for sour cream?
Yes, use a 1:1 ratio of plain Greek yogurt. The protein content will give similar tenderness, though the flavor will be slightly tangier. For best results, choose full-fat yogurt to maintain richness. If your yogurt is thick, whisk it first to achieve a smooth consistency similar to sour cream.
