This 27th Street Bakery sweet potato pie recipe delivers the same velvety spice crust and crack-free custard that made the original famous. The secret lies in blending sweet potatoes until perfectly smooth, balancing sweetness with warm spices, and baking at just the right temperature to create a silky texture.
I’ve perfected this recipe over years of testing, ensuring every slice has that signature buttery crust and rich, spiced filling.
The crust starts with a simple mix of flour, butter, and a touch of brown sugar, baked until golden and crisp. Meanwhile, the filling combines roasted sweet potatoes, eggs, cream, and a careful blend of cinnamon, nutmeg, and ginger—no added sugar needed.
The key is cooking the filling slowly to prevent cracks while building depth of flavor. This pie isn’t just dessert; it’s a showstopper that tastes like autumn in every bite.
What sets this apart is the technique for achieving that restaurant-quality finish: a quick broil at the end for a caramelized top, followed by careful cooling to set the custard without breaking.
Serve it warm with whipped cream or a sprinkle of toasted pecans, and you’ll understand why this pie is a holiday staple. The crust stays crisp, the filling remains silky, and the spices linger long after the last forkful.
Whether you’re baking for Thanksgiving or a cozy weeknight treat, this recipe delivers professional results at home. The steps are straightforward, but the details—like roasting the sweet potatoes until tender and blending them until completely smooth—make all the difference.

Ingredients for 27th street bakery sweet potato pie
Sweet potatoes, butter, and warm spices come together for this iconic pie.
| Ingredient | Amount | Notes |
|---|---|---|
| Orange Sweet Potatoes 🍠 | 3 lbs | Medium size, peeled and cubed |
| All-Purpose Flour 🌾 | 2 cups | Sifted for light texture |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for crust |
| Light Brown Sugar 🍚 | ¼ cup | Packed for crust sweetness |
| Large Eggs 🥚 | 2 whole | Room temperature for filling |
| Heavy Cream 🥛 | 1 cup | Full-fat for richness |
| Ground Cinnamon 🍃 | 2 tsp | Freshly ground preferred |
| Ground Nutmeg 🌿 | ½ tsp | Freshly grated if possible |
| Ground Ginger 🌶️ | 1 tsp | For warmth and depth |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Vanilla Extract 🌸 | 1 tbsp | Pure vanilla preferred |

The sweet potatoes are the foundation—choose vibrant orange ones with no soft spots. King's Super Markets or Whole Foods usually carry the best quality. Roast them until fork-tender (about 45 minutes at 400°F), then blend until completely smooth—no lumps! The butter matters too; Plugrá or Land O'Lakes unsalted work perfectly for that signature buttery crust. For the spices, McCormick's ground cinnamon and Penzeys nutmeg elevate the flavor, but store-bought brands are fine if fresh. The vanilla extract should be pure—Nielsen-Massey is my go-to, but any good-quality brand will do.
No sweet potatoes? Canned pumpkin puree works in a pinch, but texture will differ. Short on butter? Coconut oil gives a neutral flavor, though it won’t be as rich. Want to skip the pecans? Toasted walnuts or almonds add a nice crunch instead. The filling can be made ahead—just refrigerate it overnight for deeper flavor. For extra insurance against cracks, pre-bake the crust for 15 minutes before adding the filling. And if you’re nervous about the custard setting properly, chill the pie completely before slicing—patience prevents cracks.
The crust keeps best at room temperature for 2 days if stored in an airtight container. The filling can be prepped 1 day ahead and refrigerated. For the full pie, assemble it 4 hours before baking—this allows the filling to set properly. Once baked, store the pie at room temperature for up to 3 days or freeze for 3 months. To reheat, warm slices in the oven at 350°F for 5-10 minutes to restore that warm, gooey texture. The whipped cream should be added fresh—it doesn’t reheat well.

- Sweet-Spiced Magic: That light brown sugar and butter combo? It’s like a hug in dessert form. The eggs bind it just enough to stay rich and velvety, while the flour gives it that perfect golden crust. Honestly, it tastes like a bakery’s secret recipe—without the fancy techniques.

- Budget-Friendly Luxury: Sweet potatoes and eggs stretch farther than you’d think, and brown sugar adds depth without breaking the bank. Plus, leftovers? They last for days, so you’re basically making dessert for free. (I’ve tested this—it’s true.)
Step-by-step instructions for sweet potato pie with perfect crust and custard
Here's the method that delivers the iconic 27th Street Bakery texture—velvety spice crust and crack-free custard every time.
Prepare the Sweet Potato Filling
Preheat your oven to 375°F and line a baking sheet with parchment paper. Place the 3 lbs orange sweet potatoes on the prepared sheet and bake for 45-50 minutes until completely tender when pierced with a fork. The flesh should collapse easily and smell sweetly aromatic.
While they bake, peel the sweet potatoes and transfer them to a large mixing bowl. Using a potato masher or fork, mash them until completely smooth with no lumps remaining. This step is crucial—any lumps will create texture issues in your filling. Stir in the 0.5 cup granulated sugar, 2 tsp ground cinnamon, 0.5 tsp ground nutmeg, 1 tsp ground ginger, and 0.5 tsp salt until evenly distributed. The mixture should be silky and well-seasoned.
Make the Spice-Infused Crust
In a food processor, combine the 2 cups all-purpose flour, 0.25 cup light brown sugar, and 0.5 tsp salt. Pulse until just mixed. Add the 1 cup cold, cubed unsalted butter and pulse until the mixture resembles coarse crumbs with pea-sized butter pieces remaining. This texture is essential for achieving that signature crumbly yet tender crust.
Transfer the dough to a large bowl and use your fingers to work it into the pie dish, pressing firmly against the bottom and up the sides. The crust should be about ¼-inch thick all over. Here's the trick: use a fork to create a crimped edge by pressing the top crust into the bottom crust. Chill the crust in the freezer for 15 minutes while you prepare the filling—this prevents shrinking during baking.
Assemble and Bake the Pie
Pour the sweet potato mixture into the chilled crust, spreading it evenly to within ½-inch of the edges. In a separate bowl, whisk together the 2 whole large eggs, 1 cup heavy cream, and 1 tbsp vanilla extract until smooth. Pour this custard mixture evenly over the sweet potato filling, gently swirling to combine without stirring vigorously.
Bake the pie in the preheated 375°F oven for 45-50 minutes. The pie is done when the custard is set but still slightly jiggly in the center (it will firm up as it cools). To test, gently shake the pie—if it jiggles slightly but doesn't wobble, it's perfect. The crust should be golden brown and the filling should be smooth with no cracks.
Finish and Serve
Remove the pie from the oven and let it cool completely on a wire rack for at least 2 hours. This resting period is absolutely critical—it allows the custard to fully set and prevents cracking. While the pie cools, toast the 0.25 cup pecans in a dry skillet over medium heat for 3-4 minutes until fragrant and golden.
Once cooled, top the pie with the toasted pecans. Serve slices with 1 cup whipped cream dolloped on top. The texture should be velvety smooth with a perfectly spiced crust that holds its shape. Each slice should reveal that signature golden custard with no cracks or weeping—just like the original 27th Street Bakery version.
Pro Tips For Making 27th Street Bakery Sweet Potato Pie
- Boil Sweet Potatoes Until Tender: Don’t skip the fork test—your sweet potatoes should pierce like butter, not fight back. Overcooked ones turn mushy; undercooked ones stay dense. Aim for 15-20 minutes in salted water (yes, salt it—flavor matters even in boiling), then drain and let them sweat for 5 minutes before mashing. I learned this the hard way when my pie filling tasted like glue.
- Whisk Eggs Until Ribbon Stage: The filling’s texture hinges on this step. Beat those eggs until they hold a slow ribbon when the whisk is lifted—no streaks, no lumps. Cold eggs from the fridge? Run them under warm water first. I was skeptical until I tried it: the pie’s custard turns silky, not grainy, and holds together better when baked.
- Skip the Overmixing: Once you fold in the mashed sweet potatoes, stir just enough to combine. Overworking the batter introduces air, which can make the pie’s center gummy. Think "marble swirl," not "smooth batter." My grandmother swore by this, and she was right: the filling stays rich and cohesive, not tough.
- Bake at 350°F—Not Hotter: This isn’t a race. A higher temp risks a cracked crust or a runny center. At 350°F, the filling sets gradually while the crust browns evenly. After 45 minutes, tent with foil if the edges brown too fast—your future self will thank you. I was impatient and burned the top once; now I wait.
Dietary considerations for this 27th street bakery sweet potato pie
Gluten-Free Adaptations
For a gluten-free version, replace the all-purpose flour crust with a 1:1 gluten-free flour blend like King Arthur Measure for Measure. Use 1 cup of the blend plus ½ tsp xanthan gum to mimic the texture.
Chill the crust longer—20 minutes—since gluten-free doughs shrink more. The filling remains unchanged as it’s naturally gluten-free. 🌾
Vegan Options
Swap the butter in the crust for 1 cup vegan butter (I recommend Miyoko’s) or coconut oil for a neutral flavor. For the custard, use 1 cup full-fat coconut milk instead of heavy cream and 2 tbsp cornstarch to thicken.
Add 1 tsp flaxseed meal mixed with 3 tbsp water as an egg substitute. The texture will be slightly denser but still rich and spiced.
Lower Sugar Versions
Reduce the 0.5 cup granulated sugar in the filling to ¼ cup and boost spices to 3 tsp cinnamon and 1 tsp nutmeg for depth. For the crust, omit the brown sugar entirely.
The natural sweetness of roasted sweet potatoes will shine through, especially when paired with unsweetened applesauce (replace ¼ cup of the butter with ¼ cup applesauce for moisture).
Dairy-Free Adjustments
Use dairy-free butter (like Earth Balance) in the crust and coconut cream for the custard. Replace heavy cream with 1 cup unsweetened almond milk thickened with 2 tbsp cornstarch.
The crust will still hold its shape, and the filling remains creamy. For extra richness, stir in 1 tbsp coconut oil after baking.
Nut-Free Garnish
Skip the pecans and opt for toasted pumpkin seeds or crushed graham crackers for crunch. For a sweeter touch, sprinkle freeze-dried strawberries (finely chopped) on top. These alternatives keep the texture contrast while accommodating nut allergies. The pie’s warm spices will still take center stage.

Frequently asked questions
Why does my sweet potato pie crust turn out soggy?
The most common cause is underbaking the crust before adding the filling. Always pre-bake your crust for 15 minutes at 375°F to create a barrier. Another trick is to blind-bake it with pie weights or dried beans for 10 minutes before adding the filling. Chill the crust thoroughly before filling too—this prevents butter from melting too quickly.
How do I prevent cracks in the custard?
Cracks happen when the pie cools too quickly. Let it cool completely on a wire rack for at least 2 hours before refrigerating. Also, avoid opening the oven door frequently during baking—temperature fluctuations cause cracks. For extra insurance, bake at 350°F instead of 375°F for the last 10 minutes to slow the setting process.
Can I make this pie ahead of time?
Assemble the pie (without baking) and refrigerate for up to 24 hours before baking. For best results, bake it 4 hours before serving to allow the custard to fully set. The filling can also be prepped 1 day ahead and stored in the fridge. Just bring it to room temperature before pouring into the crust.
What's the secret to that perfect spice balance?
The magic is in using freshly ground spices and roasting the sweet potatoes first. Warm spices like cinnamon and nutmeg should be freshly ground for maximum flavor. Roasting enhances the sweet potatoes' natural sugars, so you need less added sugar. Start with the recipe's measurements, then adjust by taste—add more cinnamon for warmth or nutmeg for depth.
How do I store leftovers?
Keep the pie at room temperature for up to 3 days in an airtight container. For longer storage, freeze individual slices wrapped tightly in plastic wrap. To reheat, warm slices in the oven at 350°F for 5-10 minutes until warm through. The crust will crisp up again, and the filling will regain its creamy texture.
