Ingredients for america's test kitchen zucchini bread
Fourteen ingredients, meticulously balanced for that signature crisp-topped, moist crumb America's Test Kitchen perfected.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 1 ½ cups | Sifted for even distribution |
| Cake Flour 🌾 | ½ cup | Ensures fine, tender crumb |
| Granulated Sugar 🍚 | 1 cup | Light brown preferred for depth |
| Packed Brown Sugar 🍚 | ½ cup | Adds moisture and chew |
| Vanilla Bean 🌿 | 1 whole | Scraped seeds and pod |
| Large Eggs 🥚 | 2 whole | Room temperature for blending |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for creaming |
| Sour Cream 🥛 | ½ cup | Full-fat for richness |
| Fresh Zucchini 🥒 | 1 ½ cups | Grated, excess liquid drained |
| Baking Soda 🧂 | 1 tsp | Diamond Crystal preferred |
| Ground Cinnamon 🌿 | 1 ½ tsp | Freshly ground for warmth |
| Salt 🧂 | ½ tsp | Fine sea salt |
| Pure Vanilla Extract 🍯 | 1 tsp | High-quality for depth |
| Chocolate Chips 🍫 | ½ cup | Semi-sweet, optional |
The vanilla bean is non-negotiable—Madagascar Bourbon from Penzeys delivers the richest depth. If you can't find whole beans, high-quality pure extract works, but the scraped seeds add complexity no bottled version can replicate. For the flours, King Arthur all-purpose and Bob's Red Mill cake flour ensure that ideal tender-yet-firm crumb. The zucchini? Young, tender varieties like 'Early Summer' yield the least moisture—avoid those watery heirlooms. Grate it yourself; pre-shredded releases too much liquid. Drain in a cheesecloth-lined colander for 10 minutes to remove excess water.
No vanilla bean? Double the pure extract and add a pinch of vanilla sugar (simmer sugar with scraped seeds from a used pod). Substituting sour cream? Greek yogurt at half the quantity works, but the fat content matters—skip the non-fat versions. Chocolate chips optional, but if using, Enjoy Life brand for allergy-friendly baking. The brown sugar can be swapped for white, but you'll lose that subtle caramel undertone. For a nutty twist, fold in 1/2 cup toasted walnuts (chopped) or pecans—just don't overmix after adding them. The butter must be cold; European-style with higher fat content yields a richer crumb.
This loaf keeps beautifully—3 days at room temperature wrapped in parchment, 1 week refrigerated in an airtight container, or 3 months frozen. To reheat, wrap cooled slices in a damp paper towel and microwave for 10 seconds—restores that bakery-fresh crispness. For gifting, slice while still warm and package in cellophane bags with a vanilla bean scraped into the sugar. The bread freezes best at the underbaked stage (5 minutes less than recipe time)—finish baking from frozen for even results. Portion into single-slice wraps for easy grab-and-go mornings.
Why You'll Love This Recipe
- No Mixing Madness: I swear by this recipe because it’s the only zucchini bread that doesn’t require folding in grated veggies—just blend the zucchini right into the wet ingredients. One bowl, no lumps, no stress. The cake flour keeps it tender without being gummy, and honestly? That’s half the battle won before you even preheat the oven.
- Sweet-Spiced Magic: Between us, the combo of brown sugar and vanilla bean is chef’s kiss—deep caramel notes with that bright, luxurious vanilla punch. The granulated sugar cuts through the richness just enough, and the texture? Moist but not heavy, with a crumb so fine it practically melts. It’s the kind of flavor that makes you reach for a second slice before you even leave the kitchen.
- Weeknight Workhorse: This bread bakes up perfectly in one loaf pan, but here’s the real win: it’s my go-to for breakfast, snacks, or even dessert. Toast it for a quick protein boost with peanut butter, pack it for lunches, or serve it warm with a smear of cream cheese. (Yes, even on a Tuesday night when you’re too tired to think.)
- Budget-Friendly Staple: I make this at least once a month because it’s ridiculous how little it costs to feed a crowd. The cake flour adds a premium texture without breaking the bank, and the zucchini stretches the batter so you get two loaves for the price of one. Plus, it freezes like a dream—just slice and toast whenever you need a fast, no-fuss treat.
Step-by-step instructions for america's Test Kitchen zucchini bread
Mastering this recipe delivers a tender crumb and signature crisp-topped crust—every detail matters.
Prepare the Zucchini and Vanilla Infusion
Begin by grating the 1.5 cups fresh zucchini using the fine holes of a box grater. Transfer to a clean kitchen towel and squeeze firmly to remove excess moisture—this prevents a gummy texture. Meanwhile, split the whole vanilla bean lengthwise and scrape the seeds into a small bowl. Add the seeds and 1 teaspoon pure vanilla extract to the grated zucchini mixture and set aside.
This step ensures maximum moisture retention while infusing the bread with deep vanilla flavor. The drained zucchini should yield about 1 cup of packed grated zucchini—measure it before proceeding to confirm proper yield. If you're using pre-grated zucchini from a package, drain it thoroughly through a fine-mesh sieve first.
Cream Butter and Sugars for Optimal Texture
In a stand mixer fitted with the paddle attachment, combine the ½ cup unsalted butter (cold and cubed) with the 1 cup granulated sugar and ½ cup packed brown sugar. Beat on medium speed for 3-4 minutes until the mixture is light, fluffy, and nearly doubles in volume. This creaming process incorporates air, which creates that signature tender crumb.
Stop occasionally to scrape down the sides of the bowl with a rubber spatula—this ensures even mixing. The butter should be completely incorporated with no visible lumps, and the mixture should look pale and thick. If you press your finger into the mixture, it should leave a slight indentation that holds its shape.
Combine Wet Ingredients and Fold in Dry Components
Add the 2 whole large eggs (room temperature) one at a time, mixing on low speed after each addition until fully incorporated. Then stir in the ½ cup sour cream and the prepared zucchini-vanilla mixture. The batter will appear slightly curdled at this stage—this is normal and will resolve in the next step.
In a separate bowl, whisk together the 1½ cups all-purpose flour, ½ cup cake flour, 1½ teaspoons ground cinnamon, ½ teaspoon salt, and 1 teaspoon baking soda. With the mixer on low speed, gradually add the dry ingredients to the wet mixture, mixing just until combined. Avoid overmixing—stop as soon as the flour disappears. Fold in the ½ cup chocolate chips by hand using a silicone spatula.
Bake for Moist Crumb and Crisp Top
Preheat your oven to 350°F and grease a 9x5-inch loaf pan thoroughly with butter or nonstick spray. Pour the batter into the prepared pan and smooth the top with an offset spatula. Bake for 50-55 minutes, or until a toothpick inserted in the center comes out clean and the top is deep golden brown with a crisp crust.
I recommend tenting the pan with aluminum foil after 30 minutes of baking if the top begins to brown too quickly—this prevents over-browning while allowing the bread to cook through. The internal temperature should reach 205-210°F at the center. Let the bread cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.
Rest and Serve for Maximum Moisture
Allow the zucchini bread to cool completely before slicing—this ensures clean cuts and prevents crumbling. The bread will be moist but not sticky when properly baked. For best results, wrap any leftovers tightly in plastic wrap and store at room temperature for up to 3 days, or refrigerate for up to 5 days. Reheat slices in a 350°F oven for 5-7 minutes to restore freshness.
The secret to maintaining moisture lies in the sour cream and proper baking time. If the bread feels dry when sliced, it likely needed an additional 5-10 minutes in the oven. Each slice should be tender with a slightly chewy texture from the brown sugar, complemented by the crisp top and bursts of vanilla-chocolate flavor throughout.
Pro Tips For Making America'S Test Kitchen Zucchini Bread
- Measure Brown Sugar Properly: The recipe calls for packed brown sugar—don’t scoop it straight from the bag. Use a spoon to press it firmly into the measuring cup, then level it off. I learned this the hard way when my first batch turned out denser than a brick (and yes, that’s why it stayed fresh for weeks).
- Whisk the Flour Mixture: The recipe combines cake flour, all-purpose flour, and spices—whisk them together before adding to the wet ingredients. I used to just dump them in, and the texture always came out uneven. Five minutes with a fork makes a real difference.
- Don’t Overmix the Batter: Once you add the flour mixture, mix just until combined—no need to stir like you’re trying to win a baking contest. Overmixing makes zucchini bread tough, and this recipe relies on that tender crumb. Stop when there are a few dry spots left.
- Use a Toothpick Test: The recipe’s bake time is a range, but don’t guess. Insert a toothpick into the center—if it comes out clean (or with a single crumb), it’s done. I’ve pulled loaves early and ended up with a gummy center that ruined the whole slice. Better to wait.
Wine and beer pairings for these flavors
Light White Wine
Zucchini bread’s delicate vanilla and cinnamon notes pair beautifully with crisp, dry whites. I reach for a Sauvignon Blanc from New Zealand—its zesty citrus and herbal undertones cut through the bread’s richness without overpowering it.
A Pinot Grigio from Italy also works perfectly, especially if your bread has a touch of lemon zest. Serve slightly chilled for the best contrast. 🍷
Sweet Riesling
For a dessert-like experience, a German Riesling with its honeyed sweetness and bright acidity mirrors the bread’s caramelized top and vanilla depth. Look for a Kabinett or Spätlese—the slight sweetness enhances the chocolate chips if you added them.
This pairing feels indulgent yet balanced, ideal for afternoon tea or brunch. 🍇
Craft Beer Options
A light Belgian witbier like Hoegaarden brings refreshing citrus and coriander notes that complement the zucchini’s natural sweetness. For a bolder match, try a honey ale—the malty sweetness and subtle spice echo the bread’s cinnamon and brown sugar.
Avoid heavy stouts or IPAs, which can clash with the delicate flavors. 🍺
Coffee or Tea
Skip the alcohol? A dark roast coffee with notes of chocolate and caramel pairs surprisingly well, especially if your bread has chocolate chips. For a lighter option, Earl Grey tea—its bergamot aroma enhances the vanilla and cinnamon.
Serve the bread warm with a cup of either for a comforting pairing. ☕
Seasonal Adaptations
In summer, a sparkling rosé with its crisp acidity refreshes the palate after each bite. For fall, a dry Riesling or Chardonnay with oak notes adds warmth. Winter calls for a Moscato d’Asti—its light fizz and berry sweetness balances the bread’s richness. Adjust based on the season’s flavors! 🍂

Frequently asked questions
Why does this zucchini bread recipe use both all-purpose and cake flour?
The combination creates the perfect texture—all-purpose flour provides structure while cake flour keeps the crumb tender and fine. This blend prevents a dense, heavy loaf while maintaining moisture balance. The recipe relies on this ratio to achieve that signature crisp-topped, soft interior you'd expect from America's Test Kitchen.
Can I substitute sour cream with something else?
Yes, but with adjustments. Use ½ cup Greek yogurt (full-fat works best) or ½ cup buttermilk—both add moisture and richness. Avoid non-fat versions as they won't replicate the tender crumb. The sour cream's fat content is key for that perfect texture, so don't skip it if possible.
How do I fix a dry zucchini bread?
If your bread turns out dry, it likely needed more baking time or moisture. Try reheating slices in a 350°F oven for 5-7 minutes to restore freshness. For next time, ensure you drained the zucchini thoroughly and consider adding 1 tablespoon extra sour cream or a splash of milk to the batter. The internal temperature should reach 205-210°F at the center for optimal moisture.
What's the best way to store leftover zucchini bread?
Wrap tightly in plastic wrap and store at room temperature for up to 3 days or refrigerate for 5 days. For longer storage, freeze slices wrapped individually—they'll stay fresh for 3 months. To reheat, wrap cooled slices in a damp paper towel and microwave for 10 seconds to restore crispness. The bread freezes best at the underbaked stage for even results.
Can I make this recipe without a vanilla bean?
Use 2 teaspoons high-quality pure vanilla extract plus a pinch of vanilla sugar (simmer sugar with scraped seeds from a used pod). For extra depth, add ½ teaspoon almond extract, but use sparingly—vanilla bean's unique flavor is hard to replicate. The recipe's signature aroma comes from that whole bean infusion, but this works in a pinch.
