Ingredients for america's test kitchen pumpkin bread

Precision meets tradition in this science-tested pumpkin bread with signature spiced swirls.

Ingredient Amount Notes
Canned Pumpkin Puree 🎃 1 ½ cups Unsweetened, 100% pumpkin
All-Purpose Flour 🌾 2 ½ cups Sifted, spooned and leveled
Light Brown Sugar 🍯 1 ½ cups Packed firmly, not compacted
Granulated Sugar 🍚 ½ cup For balanced sweetness
Unsalted Butter 🧈 1 cup Cold, cubed, not melted
Large Eggs 🥚 2 whole Room temperature
Pure Vanilla Extract 🌸 1 tbsp High-quality, not imitation
Ground Cinnamon 🌶️ 2 tsp Freshly ground, not pre-mixed
Ground Nutmeg 🌿 ½ tsp Freshly grated preferred
Ground Ginger 🌶️ 1 tsp Freshly ground for potency
Salt 🧂 1 tsp Diamond Crystal preferred
Molasses 🍯 ¼ cup Unsulphured, dark variety
Spiced Swirl Mixture 🎃 1 cup Cinnamon, nutmeg, ginger mix

The pumpkin puree is non-negotiable—Libby’s 100% pure canned pumpkin is the gold standard, but any unsweetened brand works. For the flour, King Arthur or Bob’s Red Mill are ideal due to their protein consistency, which ensures proper crumb structure. Brown sugar should be packed firmly but not compacted—use a 16-ounce measuring cup for accuracy. The molasses adds depth; Annie’s or Brer Rabbit unsulphured molasses deliver the richest flavor. Store your spices in airtight containers away from light—they lose potency fast, especially nutmeg, which is critical for that warm autumnal note.

No vanilla extract? Vanilla bean paste at half the amount works beautifully, though it adds texture. Short on molasses? Maple syrup at a 1:1 ratio is a decent swap, but the flavor profile shifts slightly. The spiced swirl mixture should be made fresh—Penzeys brand spices are worth the investment for this recipe. If you’re gluten-sensitive, King Arthur gluten-free flour blend works, though texture will differ. For the butter, Plugrá or Land O’Lakes unsalted are reliable choices, but avoid salted—it throws off the delicate balance. The eggs must be room temperature to ensure even blending and proper rise.

This bread stays moist for 5 days at room temperature, wrapped in foil. For longer storage, freeze slices in a sealed bag for up to 3 months. The swirl technique is key—don’t overmix the batter, as this can lead to a dense crumb. For a restaurant-quality finish, brush the warm loaf with simple syrup (equal parts sugar and water, heated until dissolved) before serving. The bread reheats beautifully—wrap a slice in foil and warm in a 350°F oven for 5-10 minutes to restore its softness.

Step-by-step instructions for america's test kitchen pumpkin bread

Master the science of moist pumpkin bread with these precision techniques.

1

👨‍🍳 Step 1: Cream Butter and Sugars for Optimal Texture

In a stand mixer fitted with the paddle attachment, combine the 1 cup unsalted butter (cold and cubed) with the 1.5 cups light brown sugar and 0.5 cup granulated sugar. Beat on medium speed for 3-4 minutes until the mixture is light, fluffy, and nearly doubles in volume. You're looking for a pale, ribbon-like consistency that leaves clean streaks when the paddle is lifted.

This creaming process incorporates air into the butter, creating a tender crumb. I press down on the butter mixture with a spatula during the first minute to break up any large lumps—this prevents grainy texture. The butter should be fully emulsified with the sugars but not melted into a liquid state.

2

👨‍🍳 Step 2: Incorporate Wet Ingredients for Perfect Moisture Balance

Add the 1.5 cups canned pumpkin puree, 2 whole large eggs (room temperature), 1 tbsp pure vanilla extract, and 0.25 cup molasses to the butter-sugar mixture. Beat on medium speed for 1-2 minutes until fully combined and smooth. The batter should be thick but pourable—like heavy pudding.

Here's where the molasses comes into play: it adds depth of flavor and helps prevent dryness. I like to scrape down the sides of the bowl with a rubber spatula every 30 seconds to ensure even mixing. The pumpkin puree should be completely incorporated without any streaks remaining.

3

👨‍🍳 Step 3: Combine Dry Ingredients and Prepare Swirl Dough

In a separate bowl, whisk together the 2.5 cups all-purpose flour, 2 tsp ground cinnamon, 0.5 tsp ground nutmeg, 1 tsp ground ginger, and 1 tsp salt. Gradually add this dry mixture to the wet ingredients, mixing on low speed just until combined—about 30 seconds. Overmixing develops gluten, which can make the bread tough.

For the spiced swirls, take 1 cup of the batter and set it aside in a small bowl. To this reserved batter, add 1 cup spiced swirl mixture and mix until just combined. The swirl dough should be slightly thicker than the main batter but still smooth.

4

🍳 Step 4: Layer and Bake for Even Moisture Distribution

Preheat your oven to 350°F and grease two 9x5-inch loaf pans thoroughly with butter. Divide the main batter evenly between the pans, spreading it out to the edges. Drop spoonfuls of the spiced swirl dough onto each loaf, spacing them about 1 inch apart. Use a knife to gently swirl the dough through the batter in a circular motion.

Bake for 50-60 minutes until a toothpick inserted in the center comes out clean and the top is deep golden brown. The bread is done when the edges pull away slightly from the pan and the internal temperature reaches 205-210°F. I like to tent the pans with foil after 30 minutes to prevent over-browning if my oven runs hot.

5

⏰ Step 5: Cool and Slice for Maximum Moisture Retention

Remove the bread from the oven and let it cool in the pans for 10 minutes. Then transfer to a wire rack to cool completely. This gradual cooling prevents cracking and allows the crumb to set properly. The bread should be moist but not gummy—if it feels too dense, it likely needs a few more minutes in the oven.

Slice the bread while still slightly warm for clean cuts and maximum moisture. Store wrapped at room temperature for up to 3 days or freeze for longer storage. The molasses and pumpkin combination keeps this bread moist for days, while the swirls add beautiful contrast with every bite.

Pro Tips For Making America'S Test Kitchen Pumpkin Bread

  • Mix Dry First: Combine the flour, spices, baking soda, and salt before adding wet ingredients—this prevents lumps in the pumpkin puree. I used to toss them in one by one, and the batter always ended up thicker than the recipe intended. Save yourself the headache and weigh the dry ingredients together first.
  • Butter at Room Temp: Let the butter sit out for 30–45 minutes before creaming—this ensures it blends smoothly with the sugars. Cold butter creates pockets of air that don’t dissolve, leading to a denser loaf. (Yes, even if you’re impatient like me.)
  • Don’t Overmix the Batter: Stir just until the flour disappears—overmixing develops gluten, which makes the bread tough. I learned this the hard way after a batch turned out like a dense brick. Use a spatula and stop when it’s just combined.
  • Test for Doneness Early: Check the bread at 50 minutes with a toothpick—it should come out clean but slightly moist. The recipe’s 55–60 minute range is a guideline, not a rule. Ovens vary, and waiting too long dries out the crumb. (Your future self will thank you.)

Perfect pairings for this recipe

Buttercream Frosting

Top your pumpkin bread with a smooth vanilla buttercream made from ½ cup unsalted butter, 2 cups powdered sugar, 2 tbsp milk, and 1 tsp vanilla extract.

Beat until fluffy and spread evenly over the cooled loaf. For extra richness, I add 1 tbsp pumpkin puree to the frosting to complement the bread’s natural sweetness. 🎃

Cream Cheese Glaze

A tangy cream cheese glaze elevates the bread’s flavors perfectly. Mix 4 oz cream cheese, ½ cup powdered sugar, and 1 tbsp lemon juice until smooth.

Drizzle over the warm loaf for a bright contrast to the spiced swirls. This glaze also keeps the bread moist for days when stored properly.

Caramel Drizzle

For a decadent touch, drizzle warm salted caramel over the top of the bread. Use ½ cup store-bought caramel sauce (like Smucker’s) or homemade caramel made with 1 cup brown sugar and ¼ cup heavy cream.

Sprinkle with flaky sea salt for a sweet-salty balance that pairs beautifully with the pumpkin’s natural sweetness. ✨

Whipped Cream

Serve slices of pumpkin bread with a dollop of lightly sweetened whipped cream for a dessert-like finish. Whip ½ cup heavy cream with 1 tbsp powdered sugar and a pinch of cinnamon for extra warmth. This adds a cloud-like texture that contrasts the bread’s dense crumb.

Spiced Whipped Cream

For a flavor boost, infuse the whipped cream with spices. Warm ½ cup heavy cream with ½ tsp cinnamon and ¼ tsp nutmeg, then chill before whipping. The spices meld beautifully with the pumpkin bread, creating a cohesive autumnal flavor profile. This is my go-to for holiday gatherings! 🌿

Coffee or Tea Pairings

Enhance your experience by pairing this bread with a dark roast coffee or chamomile tea. The bitterness of coffee cuts through the sweetness, while the warmth of tea complements the spices. For a festive touch, try spiced chai—the cardamom and cloves mirror the bread’s warm flavors. 💫

Frequently asked questions

1

Why does this pumpkin bread stay moist for days?

The secret lies in the combination of molasses and pumpkin puree, which retain moisture better than traditional recipes. The precise ratio of brown sugar to granulated sugar also creates a tender crumb that resists drying out. Plus, the swirled spice mixture adds flavor without altering the moisture balance.

2

Can I make this recipe without molasses?

Yes, but the flavor will be slightly different. Replace the 0.25 cup molasses with 0.25 cup maple syrup or 0.25 cup honey for a similar sweetness level. The molasses adds depth and helps maintain moisture, so you may need to add 1 extra tablespoon of liquid (like milk or pumpkin puree) if substituting.

3

What's the best way to store leftover pumpkin bread?

Wrap the cooled loaf tightly in plastic wrap or foil and store at room temperature for up to 5 days. For longer storage, slice the bread and freeze individual portions in a sealed bag for up to 3 months. To reheat, wrap a slice in foil and warm in a 350°F oven for 5-7 minutes for maximum softness.

4

How do I fix a dense or dry pumpkin bread?

Density often comes from overmixing the batter—mix dry ingredients just until combined (30 seconds max). For dryness, ensure you used unsweetened pumpkin puree and didn't overbake. If it's already baked, try brushing warm slices with simple syrup (equal parts sugar and water) to restore moisture.

5

Can I add nuts or chocolate chips to this recipe?

For texture, fold in 1 cup chopped walnuts or pecans with the dry ingredients. For sweetness, add ½ cup mini chocolate chips or chopped dark chocolate. Just reduce the flour by 2 tablespoons to maintain the proper batter consistency. The swirl technique will still work beautifully with these additions.
