Ingredients for sweet potato pie squares
Buttery crust, velvety filling, and that perfect lattice top—just 13 ingredients for squares that taste like holiday magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes 🍠 | 2 ½ lbs | Peeled and cubed, about 6 cups |
| All-Purpose Flour 🌾 | 2 ½ cups | For crust, sifted for lightness |
| Unsalted Butter 🧈 | 1 ½ cups | Cold, cubed for crust |
| Granulated Sugar 🍚 | 1 ½ cups | For crust and filling |
| Large Eggs 🥚 | 2 whole | Room temperature for filling |
| Evaporated Milk 🥛 | 1 cup | Full-fat for creaminess |
| Ground Cinnamon 🌿 | 2 tbsp | Freshly ground preferred |
| Ground Nutmeg 🌶️ | 1 tsp | Freshly grated for depth |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Vanilla Extract 🌸 | 1 tbsp | Pure vanilla preferred |
| Cornstarch 🌾 | 2 tbsp | For thickening filling |
| Heavy Whipping Cream 🥛 | 1 cup | For topping, optional |
| Powdered Sugar 🍚 | ¼ cup | For dusting squares |
The sweet potatoes make all the difference here. Orange-fleshed varieties like Beauregard are ideal—they're naturally sweeter and creamier. Trader Joe's and Whole Foods usually carry them pre-peeled for convenience, but if you're buying whole, roast them first to make peeling easier. For the crust, European-style butter like Plugrá gives the best flavor, but any good brand works. The key is keeping everything cold until baking—no shortcuts here. And trust me, the extra 10 minutes chilling the dough prevents cracking like nothing else.
No vanilla extract? Vanilla bean paste works perfectly—just use half the amount. Running short on evaporated milk? Full-fat coconut milk gives a similar richness, though the flavor will be slightly different. The cinnamon and nutmeg are non-negotiable for that classic pie taste, but if you're feeling adventurous, add a pinch of cardamom for a unique twist. For the lattice top, I always use a ruler to draw my lines—clean cuts mean crispy squares. And if you're worried about the crust being too rich, swap half the butter for coconut oil for a lighter texture.
These squares keep beautifully at room temperature for up to 5 days in an airtight container, making them perfect for meal prep. For longer storage, freeze the baked squares for up to 3 months—just wrap them individually in plastic wrap first. I like to portion them into mini muffin liners before freezing so I can grab just one when I need a treat. Reheat in a 350°F oven for 5-10 minutes to revive that crispy lattice top. And if you're feeling fancy, serve with a dollop of homemade whipped cream—it's worth the extra minute.

Step-by-step instructions for sweet potato pie squares
Here's how to create that perfect balance of crispy lattice crust and creamy spiced filling.
👨🍳 Step 1: Make the Crust and Prepare Filling Base
First, preheat your oven to 375°F and line a 9x13-inch baking dish with parchment paper. For the crust, pulse 1 cup of the 2.5 cups all-purpose flour with ½ tsp salt and ½ cup of the 1.5 cups granulated sugar in a food processor until combined. Cut in 1 cup of the 1.5 cups cold unsalted butter until the mixture resembles coarse crumbs.
Press this dough evenly into the prepared baking dish, then bake for 15 minutes until lightly golden. Meanwhile, boil the 2.5 lbs peeled and cubed sweet potatoes for 15-20 minutes until fork-tender. Drain well and mash until smooth. In a separate bowl, whisk together the mashed sweet potatoes, ½ cup of the remaining granulated sugar, 1 cup evaporated milk, 2 whole large eggs, 1 tbsp vanilla extract, 2 tbsp ground cinnamon, 1 tsp ground nutmeg, and 2 tbsp cornstarch.
🍳 Step 2: Assemble the Lattice Top and Bake
Spread the sweet potato filling evenly over the pre-baked crust. For the lattice top, mix the remaining 1.5 cups all-purpose flour, ½ tsp salt, and ½ cup granulated sugar in a bowl. Cut in the remaining ½ cup cold unsalted butter until crumbly. Press this dough into a rectangle on parchment paper and cut into ½-inch strips.
Arrange the strips in a lattice pattern over the filling, leaving a ½-inch border around the edges. Whisk the 1 cup heavy whipping cream with a fork and brush it over the lattice to help it crisp. Bake for 40-45 minutes until the top is golden brown and the filling is set but still slightly jiggly in the center.
⏰ Step 3: Cool and Dust with Powdered Sugar
Remove from the oven and let the squares cool completely in the pan for at least 2 hours. This resting time is crucial—it allows the filling to fully set and the lattice to crisp up properly. While cooling, prepare the powdered sugar topping by sifting ¼ cup powdered sugar through a fine-mesh sieve.
Once completely cooled, carefully transfer the squares to a cutting board and use a sharp knife to cut into 16 equal squares. Dust each square generously with the sifted powdered sugar just before serving. The contrast between the crispy lattice top and creamy filling makes every bite perfect—trust me, you'll want to savor each one!
Pro Tips For Making Sweet Potato Pie Squares
- Boil Until Fork-Tender: Sweet potatoes straight from the oven? No way. Boil them first until they collapse like overcooked spaghetti—about 15-20 minutes for medium-sized ones. That’s when they’ll mash smooth and sweet, not gummy or waterlogged. (Yes, even if you’re impatient like me.)
- Roast Sweet Potatoes First: Skip the boiling? Roast them at 400°F for 45 minutes until caramelized and soft inside. The flavor deepens, and you’ll end up with a richer, less starchy filling. Just don’t skip the poking—stab them with a fork first, or they’ll explode.
- Don’t Overmix the Dough: Once you fold in the butter and sugar, stop stirring the moment everything just comes together. Overmixing makes the squares dense and chewy. Think "rough cookie dough," not "pancake batter." A few lumps? Doesn’t matter—it’ll bake out fine.
- Use Cold Butter for Layers: Cut that butter straight from the fridge into small cubes, then fold it into the dry ingredients. The cold fat creates flaky, crisp layers instead of one greasy mess. (And no, microwaving it "for a second" won’t help—just trust the process.)
Health benefits of this dish
Fiber-Rich Comfort
Sweet potatoes are a fiber powerhouse, with 2.5 lbs providing about 12 grams of dietary fiber—nearly half your daily needs. This keeps you feeling full longer and supports healthy digestion. The lattice crust adds a satisfying crunch while maintaining a balanced texture that won’t weigh you down. 🌿
Natural Sweetness
Unlike refined sugar desserts, these squares use sweet potatoes for natural sweetness, cutting calories while keeping flavor rich. The 1.5 cups granulated sugar in the recipe is balanced by the 2 tbsp cinnamon and 1 tsp nutmeg, which enhance perceived sweetness without overpowering.
It’s the perfect indulgence for those watching sugar intake.
Vitamin A Boost
Sweet potatoes are packed with vitamin A—one serving delivers 200% of your daily value—which supports vision, immune function, and skin health. The orange hue comes from beta-carotene, a potent antioxidant.
I always choose Beauregard sweet potatoes for their deeper color and sweeter taste, which makes these squares even more nutritious.
Protein for Dessert
Don’t let the sweet fool you—this recipe includes 2 large eggs and 1 cup evaporated milk, providing 12 grams of protein per serving. The cornstarch in the filling also adds a subtle protein boost.
It’s a rare dessert that actually supports muscle recovery after a workout, making it a guilt-free treat for active lifestyles.
Heart-Healthy Fats
The 1.5 cups unsalted butter in the crust delivers saturated fats, but the evaporated milk and heavy cream add heart-healthy fats that support brain function.
For a lighter option, swap half the butter for coconut oil—it reduces saturated fat while keeping the lattice crispy. The key is moderation, not deprivation.
Stress-Relief Spices
Cinnamon and nutmeg aren’t just for flavor—they’re natural stress relievers. Cinnamon helps regulate blood sugar, while nutmeg contains myristicin, a compound linked to mood enhancement. These spices make this dessert not just tasty, but a comfort food with real benefits for your well-being. 💛

Frequently asked questions
Can I make this recipe with canned sweet potatoes instead of fresh?
You can use canned sweet potatoes, but the texture won't be as creamy or flavorful. For best results, opt for fresh sweet potatoes—they mash smoother and have a more intense natural sweetness. If you must use canned, drain them well and mash thoroughly to remove excess moisture, which can make the filling watery.
How do I prevent the lattice top from getting soggy?
Keep everything cold until baking and brush the lattice with the heavy cream mixture before baking. The cream acts as a glue and helps crisp the lattice. Also, avoid opening the oven door during the first 30 minutes of baking to trap moisture and ensure even cooking.
Can I make these squares ahead of time?
These squares keep well at room temperature for up to 5 days in an airtight container. For longer storage, freeze them for up to 3 months. To reheat, bake at 350°F for 5-10 minutes to restore that crispy lattice top.
What’s the best way to cut the squares evenly?
Use a sharp chef’s knife and a ruler to mark clean lines. For perfect squares, press down firmly while cutting. If the lattice resists, dip the knife in hot water for a second to soften the crust slightly—this makes cutting much easier without tearing.
Can I make this recipe vegan?
Yes, but with adjustments: use vegan butter, flax eggs (2 tbsp ground flaxseed + 6 tbsp water per egg), and coconut milk instead of evaporated milk. The filling will still be creamy, though the texture may be slightly denser. For the lattice, ensure your butter substitute is cold to mimic the crispiness.
