America's Test Kitchen Ultimate Banana Bread Recipe: Moist Crumb and Perfect Rise Every Time

America's Test Kitchen ultimate banana bread recipe delivers a moist crumb and perfect rise that rivals any bakery—no special equipment or tricks required. After testing dozens of variations, I've found the precise technique that ensures tender, flavorful loaves every single time.

The secret lies in precise ingredient ratios and a specific mixing method that develops gluten just enough for structure without overworking the dough.

What sets this recipe apart is the balance between moisture and structure—overmixed dough leads to tough bread, while undermixed results in a dense loaf.

I use ripe bananas (the spottier, the better) and a combination of all-purpose flour and a touch of cornstarch for that signature moist texture that keeps slices tender for days. The recipe also includes a simple butter-and-sugar creaming step that creates air pockets for that ideal rise.

By the time it emerges from the oven, you'll have a loaf with a golden-brown crust, a tender crumb that's neither dry nor gummy, and a subtle banana flavor that's balanced by warm spices.

The aroma alone will have everyone heading to the kitchen, and the first slice will confirm this is the ultimate banana bread. It's the kind of recipe that becomes a household staple, perfect for breakfast with coffee or an afternoon tea treat.

For those who love customization, you can easily add walnuts, chocolate chips, or even a swirl of peanut butter—but the classic version stands on its own. Let's get baking with this foolproof method that delivers professional-quality results at home.

Ingredients for america's test kitchen ultimate banana bread

Ripe bananas, warm spices, and precise ratios create America's Test Kitchen's ultimate banana bread—moist crumb guaranteed.

The bananas are non-negotiable—spottier means sweeter. Grab the heaviest ones at the store; they're packed with flavor. I always buy organic at Whole Foods when possible, but any grocery store's ripe bananas work. For the flour, King Arthur is my go-to—it's finely milled and perfect for baking. The cornstarch is what gives this loaf its signature moisture, so don't skip it. If you're short on time, Bob's Red Mill sells it in bulk bins, and it keeps indefinitely in the pantry. The butter? Plugrá is my absolute favorite—it's European-style and stays soft without turning greasy.

No vanilla extract? Seeds from a vanilla bean steeped in warm milk work beautifully—just crush the seeds and let them sit for 10 minutes. Short on milk? Greek yogurt at half the amount adds tang and moisture. The nutmeg can be tricky to find; Penzeys carries pre-ground if you don't want to grate it yourself. For the sugar, I use Domino brand because it's consistently fine and dissolves perfectly. If you're feeling fancy, swap half the granulated sugar for turbinado sugar—it adds subtle crunch. The baking soda needs to be fresh; if it's more than 6 months old, toss it—it loses potency fast.

This loaf keeps beautifully—3 days at room temperature wrapped in foil, or up to 5 days in the fridge. For longer storage, slice and freeze portions on a tray before bagging—3 months in the freezer with zero texture loss. I always bake two loaves; one gets eaten in a day, and the other gets sliced and frozen for quick breakfasts. The crust stays crisp even after reheating—just wrap a slice in foil and microwave for 20 seconds. Trust me, the second slice is even better than the first.

Step-by-step instructions for america's Test Kitchen ultimate banana bread recipe

Here's the method that guarantees a moist crumb and perfect rise every time—no dry, dense loaves here.

Start by peeling the 3 medium ripe bananas and mashing them thoroughly in a medium bowl using a fork or potato masher. You want a smooth, lump-free consistency—this ensures even distribution throughout the batter. The black spots on the bananas are perfect; they indicate peak sweetness and ripeness.

In a separate large bowl, cream together the 0.75 cup unsalted butter, 1 cup granulated sugar, and 0.5 cup light brown sugar on medium speed with an electric mixer until light and fluffy, about 3-4 minutes. This step incorporates air into the mixture, which creates that signature tender crumb. The butter should be at room temperature—if it's too cold, it won't cream properly, and if it's too soft, it'll make the batter greasy.

In a small bowl, whisk together the 2 cups all-purpose flour, 0.25 cup cornstarch, 0.5 tsp baking soda, 1.5 tsp ground cinnamon, 0.25 tsp ground nutmeg, and 0.5 tsp salt. Sifting these ingredients removes lumps and ensures even distribution in the batter. The cornstarch is key here—it creates that ultra-moist texture that sets this recipe apart from others.

With the mixer on low speed, gradually add the dry ingredients to the wet mixture, alternating with the 0.5 cup whole milk. Start and end with the dry ingredients to prevent a floury batter. Mix just until combined—overmixing develops gluten, which can make the bread tough. The batter should be thick but pourable, with a few small lumps still visible.

Add the mashed bananas and 2 whole large eggs to the batter, mixing on low speed until just combined. The bananas should be fully incorporated, but don't overmix—this is where the magic happens. The eggs bind everything together while adding richness. Stir in the 1 tsp pure vanilla extract last, letting its warm aroma infuse the batter fully.

Here's the thing—this batter is thick and may look like it's too much. But trust me, it's exactly what you need for that perfect rise and moist crumb. If you're worried, let it rest at room temperature for 10 minutes while you preheat your oven. This allows the flour to fully hydrate and the gluten to relax, ensuring a tender final texture.

Preheat your oven to 350°F and grease a 9x5-inch loaf pan thoroughly with butter or line it with parchment paper. Pour the batter into the prepared pan and smooth the top with a spatula. The batter will fill about 2/3 of the pan—this is intentional, as it allows for maximum rise and a domed top.

Bake for 50-60 minutes, or until a toothpick inserted into the center comes out clean. The bread is done when the top is golden brown and springs back slightly when pressed gently. Don't overbake—banana bread continues to cook as it cools, and overbaking leads to dryness. If the top browns too quickly, tent the pan loosely with aluminum foil after the first 30 minutes.

Remove the bread from the oven and let it cool in the pan for 10 minutes. This resting period allows the residual heat to finish cooking the center and sets the structure. Then, transfer the bread to a wire rack to cool completely. I know it's tempting to slice into it immediately, but resisting this urge is crucial—it ensures clean slices and prevents the bread from falling apart.

Once fully cooled, slice the bread into 1-inch thick pieces. Each slice should reveal a moist, tender crumb with a perfect balance of sweetness and spice. The cornstarch does its job, keeping the bread moist for days, while the baking soda ensures a light, airy texture. Serve warm with a pat of butter or a drizzle of honey for the ultimate indulgence.

Pro cooking tips for this recipe

Butter Temperature Matters

The butter's texture is non-negotiable for this recipe. Use Plugrá European-style butter at room temperature—it should be soft enough to press with a finger but not greasy. If your butter is too cold, it won’t cream properly, and the crumb will be dense.

If it’s too soft, the batter may become greasy. I recommend letting it sit at room temperature for 30-45 minutes before starting. Pro tip: Place your butter bowl in warm water for 10 minutes to speed up the process. 🧈

Banana Ripeness is Key

Those black-spotted bananas are your secret weapon—they’re sweeter and more flavorful than their yellow counterparts. I always buy the heaviest, spottiest bananas I can find at Whole Foods or my local grocery store.

For the best texture, mash them until completely smooth—no lumps allowed. If your bananas aren’t ripe enough, toss them in a paper bag with an apple overnight to speed up the ripening process.

Mix Just Until Combined

Overmixing is the enemy of tender banana bread. Once the dry ingredients are incorporated, stop mixing as soon as the batter comes together. The cornstarch and flour should still have a few small lumps—this prevents gluten from developing too much, which keeps the crumb soft.

If you’re using a stand mixer, switch to low speed and mix for just 10-15 seconds after the dry ingredients are added. 💡

Rest the Batter Before Baking

Let the batter rest for 10 minutes at room temperature before pouring it into the pan. This short rest allows the flour to fully hydrate and the gluten to relax, which results in a more tender loaf.

I often use this time to preheat my oven to 350°F and grease the pan. Skipping this step can lead to a denser texture, so don’t rush it—patience pays off here.

Don’t Overfill the Pan

The batter should fill the 9x5-inch loaf pan only about 2/3 full. Overfilling can cause the bread to spill over or bake unevenly. If your batter is very thick, use a spatula to smooth the top gently—this helps create a domed shape as it rises.

I also recommend lining the pan with parchment paper for easy removal and a cleaner slice. 🍞

Test for Doneness Properly

Insert a toothpick into the center of the loaf—it should come out clean or with a few moist crumbs, but no wet batter. The bread is done when the top is golden brown and springs back slightly when pressed gently.

If the top browns too quickly, tent the pan loosely with aluminum foil after 30 minutes to prevent over-browning. Overbaking is the fastest way to turn moist banana bread into a dry, sad loaf.
