Sweet potatoes are the star—look for vibrant orange ones with no soft spots. Trader Joe's often has the best organic selection, but any grocery store's fresh produce section works. The key is peeling and mashing them smooth (no lumps!) before mixing. For the crust, graham crackers from the bulk section give the best texture—just pulse them in a food processor until crumbly. If you're watching points closely, reduce the butter to 2 tbsp for the crust and use parchment paper instead.
No almond milk? Soy milk or coconut milk works just as well for creaminess. Swap maple syrup for agave or monk fruit sweetener if preferred. The spices are non-negotiable—freshly ground nutmeg and ginger make all the difference. For extra richness, add 1 tbsp of Greek yogurt to the filling (it blends right in). If you're making this ahead, prepare the filling and crust separately and assemble just before baking—prevents soggy bottoms.
Assembled pies keep for 3 days in the fridge, but honestly they taste better the next day. Reheat slices in the microwave for 20-30 seconds to restore that warm pie feeling. The crust can be made a week ahead and stored in the freezer—just press it into the pie dish and freeze. For serving, lightly toasted pecans add crunch without many points. Portion into individual slices for easy grab-and-go dessert options.

Step-by-step instructions for Weight Watchers crustless sweet potato pie
Here's how to create a velvety, spice-packed sweet potato pie without the guilt of a heavy crust.
Prepare the Sweet Potato Base
Preheat your oven to 375°F and grease a 9-inch pie dish with nonstick spray. Peel and chop the 2.5 lbs large sweet potatoes into 1-inch chunks—you want even cooking. Place them in a microwave-safe bowl and cover with water by about 1 inch.
Microwave on high for 10-12 minutes until the sweet potatoes are fork-tender. Drain the water completely and transfer the potatoes to a food processor or large bowl. Mash until completely smooth—no lumps should remain. This texture is key for that silky pie filling. Set aside to cool slightly while you prepare the other ingredients.
Mix the Filling Ingredients
In a large mixing bowl, combine the mashed sweet potatoes with the 0.5 cup light brown sugar, 0.5 cup unsweetened almond milk, and 0.25 cup pure maple syrup. Stir well to evenly distribute the sweetness. The mixture should be thick but pourable.
In a small bowl, whisk together the 2 whole large eggs, 1 tsp vanilla extract, 2 tbsp ground cinnamon, 0.5 tsp ground nutmeg, 0.5 tsp ground ginger, and 0.5 tsp salt. Gradually pour this spice mixture into the sweet potato mixture while stirring continuously. The warm spices will infuse beautifully into the filling, creating that classic sweet potato pie flavor without overpowering sweetness.
Create the Graham Cracker Crust Alternative
While the filling cools slightly, melt the 0.25 cup unsalted butter in a small saucepan over low heat. Once fully melted, remove from heat and stir in the 1.5 cups graham cracker crumbs until evenly coated. The mixture should resemble wet sand.
Press this crumb mixture firmly into the bottom of your prepared pie dish, creating an even layer. Use the back of a spoon to smooth it out. This crust alternative adds a subtle graham cracker flavor and helps prevent the filling from sticking to the dish. Bake the crust for 5 minutes at 375°F to set it slightly before adding the filling.
Assemble and Bake the Pie
Pour the sweet potato filling into the pre-baked crust, spreading it evenly with a spatula. The filling should come about ¾ of the way up the sides of the pie dish. Place the pie on the middle rack of your oven and bake for 45-50 minutes.
You'll know it's done when the filling is set but still slightly jiggly in the center (like gelatin). The edges should be golden brown, and the top should have a slight crust. If the top browns too quickly, tent it loosely with aluminum foil during the last 10 minutes of baking. Remove from the oven and let it cool completely at room temperature before serving.
Add the Whipped Cream Topping (Optional)
While the pie cools, whip the 0.5 cup light whipping cream with the 2 tbsp powdered sugar until soft peaks form. This light topping adds a creamy contrast to the spiced filling without overpowering the flavors.
Once the pie has cooled completely, spoon the whipped cream over the top and serve. Each slice of this crustless sweet potato pie delivers all the comforting flavors of traditional pie with a fraction of the calories and guilt. The texture is velvety smooth, the spices warm and inviting, and the graham cracker crust alternative adds just the right amount of crunch.
Pro Tips For Making Weight Watchers Crustless Sweet Potato Pie
- Boil Until Fork-Tender: Sweet potatoes should give slightly when pierced with a fork—no mushy centers, no rock-hard cores. I used to overcook them, and the pie turned gloppy. Aim for 20-25 minutes in boiling water, then let them cool before mashing.
- Whisk Eggs First: Mix the eggs with the almond milk before adding them to the sweet potato mixture. This prevents curdling later. I learned this the hard way—lumpy filling is a nightmare to fix.
- Measure Sugar Precisely: Light brown sugar packs differently. Scoop it into the measuring cup, then level it off with a knife—don’t just eyeball it. Too much makes the pie cloyingly sweet; too little leaves it bland.
- Bake Until Center Jiggles: The pie’s done when the edges are set but the center still wobbles slightly—like Jell-O. Overbaking turns it dry. Cover with foil halfway if your oven runs hot.
Common mistakes when making this recipe
Overmixing the Filling
I’ve ruined more sweet potato pies than I’ll admit by overmixing the filling after adding the eggs. Once you combine the eggs with the sweet potato mixture, stir just until fully incorporated—about 10-12 strokes with a spatula.
Overmixing introduces too much air, which can cause the pie to sink in the center as it bakes. The filling should look smooth but not bubbly. 🌟
Skipping the Cooling Step
Rushing to bake the pie immediately after mixing the filling is a recipe for disaster. The filling needs to sit at room temperature for at least 15-20 minutes before going into the oven.
This allows the starches to fully hydrate and the spices to meld, resulting in a velvety texture rather than a grainy one. Trust me, this small wait makes a huge difference.
Uneven Crust Pressing
The graham cracker crust alternative is where many people struggle. Press it too lightly, and the filling will leak out during baking. Press it too firmly, and it might crack or burn.
Aim for an even, ¼-inch thick layer—firm enough to hold its shape but not so dense that it becomes a brick. Use the bottom of a measuring cup to create a smooth, even surface.
Baking Time Guesses
Every oven behaves differently, so don’t rely solely on the 45-50 minute baking time. The pie is done when the center jiggles slightly like gelatin and the edges are set. Insert a knife near the center—if it comes out clean (or with just a few moist crumbs), it’s ready.
Underbaking leaves a runny filling, while overbaking turns it dry. Tent with foil if the top browns too quickly.
Ignoring the Water Bath
If you’re baking this pie in a glass or ceramic dish, consider giving it a water bath to prevent cracking. Place the pie dish in a larger roasting pan, then add 1 inch of hot water to the bottom of the pan.
This creates steam that keeps the filling moist and prevents the edges from drying out. It’s especially helpful if your kitchen runs hot or dry.
Storing Improperly
Leftover pie stored incorrectly can turn soggy or develop a skin. Always cool the pie completely before covering it with plastic wrap or an airtight container.
Store it in the fridge for up to 3 days, and if freezing, wrap it tightly in plastic and foil to prevent freezer burn. When reheating, microwave individual slices for 20-30 seconds—never reheat the whole pie at once. 💫

Frequently asked questions
Can I make this crustless sweet potato pie without eggs?
For a vegan version, replace the 2 eggs with 2 tablespoons ground flaxseed mixed with 6 tablespoons water (let it sit for 5 minutes to thicken). Alternatively, use ¼ cup unsweetened applesauce or 2 tablespoons cornstarch mixed with 2 tablespoons water. The texture will be slightly denser but still delicious.
How many Weight Watchers points is this pie per serving?
Each slice (1/6 of the pie) typically earns about 3-4 points on the current WW program, depending on your personal plan settings. The crustless version cuts points significantly compared to traditional pies. For exact tracking, enter the ingredients into the WW app—this recipe prioritizes low-calorie, high-flavor ingredients to keep it guilt-free.
What if I don't have graham crackers for the crust?
No problem! Try these alternatives: 1.5 cups crushed digestive biscuits (like Digestive or Lotus), 1 cup crushed vanilla wafers, or even ½ cup crushed pretzels mixed with 1 tbsp melted butter. For a nutty option, use 1 cup crushed pecans or walnuts. Just adjust the butter to 2 tbsp for better binding.
Can I make this pie in a different size dish?
Yes, but adjust baking times accordingly. For an 8-inch dish, bake 35-40 minutes (filling will be slightly thicker). For a 9x13-inch baking dish, spread the filling ½-inch thick and bake 30-35 minutes. Always check doneness with the knife test—underbaking is better than overbaking for custard-style pies.
How can I make this pie extra protein-rich?
Boost the protein by stirring ½ cup Greek yogurt (plain or vanilla) into the filling or adding ¼ cup powdered peanut butter for a nutty twist. For a chocolate version, mix in 2 tablespoons unsweetened cocoa powder with the spices. These additions add 3-5g protein per serving while keeping the pie's signature flavor.
