How to Make Sweet Potato Pie Bars Recipe
Step 1: Prepare and Bake the Crust
First up, preheat your oven to 350°F and line an 8×8-inch metal baking pan with foil so you can easily lift the bars out later. Blend the graham crackers, sugar, and salt in a food processor until finely ground, then mix in melted butter. Press this buttery mixture evenly into the pan and bake for 10 minutes until golden and fragrant. Once done, place it on a cooling rack and let it cool completely while you prepare the filling.
Step 2: Whip Up the Sweet Potato Filling
In a large bowl, beat together your fresh sweet potato puree with sugar, eggs, whole milk, heavy cream, bourbon (or vanilla), salt, and warming spices. Mix until everything is fully combined and smooth. Pour this luscious filling over the cooled crust, spreading it evenly, then bake for 40 minutes. You want the filling to be mostly set but still with a slight wobble in the center – this guarantees a perfectly creamy texture once cooled.
Step 3: Create the Fluffy Marshmallow Topping
While the filling cools, start the marshmallow magic by whisking egg whites and cream of tartar to soft peaks. Simultaneously, heat the sugar, corn syrup, water, and salt in a saucepan until the mixture reaches 240°F on a candy thermometer. Slowly drizzle this hot syrup into the egg whites with the mixer running low, then crank the speed up to medium-high and whisk until thick, glossy, and marshmallow-fluff perfect – this takes about 7 minutes. Add vanilla to finish.
Step 4: Top and Toast
Spread the marshmallow topping evenly over your cooled sweet potato filling. For a gorgeous finish, use a kitchen torch to lightly toast the surface until golden. If you don’t have a torch, placing the pan under the broiler for about a minute works, but watch it closely – it can go from perfect to burnt in seconds! Once toasted, refrigerate the whole pan for at least 1 hour before slicing.
Pro Tips for Making Sweet Potato Pie Bars Recipe
- Use Fresh Sweet Potatoes: Fresh puree gives the best texture and flavor; canned can be watery and less vibrant.
- Don’t Overbake the Filling: The center should still wobble a bit when you take it out to keep it creamy.
- Temperature Matters in the Topping: Cooking the syrup to exactly 240°F ensures the perfect marshmallow consistency.
- Watch Your Broiler Closely: The marshmallow topping can burn in seconds, so stay attentive during toasting.
How to Serve Sweet Potato Pie Bars Recipe
Garnishes
Simple garnishes like a sprinkle of cinnamon, a few toasted pecans, or even a drizzle of caramel sauce can add a lovely finishing touch to these bars without overpowering the cozy flavors. Fresh whipped cream on the side is always a winner too!
Side Dishes
These bars shine as a stand-alone dessert, but if you’re crafting a full spread, serve them alongside vanilla ice cream or a scoop of cinnamon-spiced Greek yogurt. For a brunch vibe, pair with savory omelets or a fresh fruit salad to balance sweet and savory.
Creative Ways to Present
Cut these bars into mini squares for bite-sized party treats, or stack them with layers of whipped cream and roasted sweet potato chunks for a trifle-style presentation that’s sure to impress your guests visually and tastefully.
Make Ahead and Storage
Storing Leftovers
Store your Sweet Potato Pie Bars covered in an airtight container in the refrigerator. They’ll stay fresh and delicious for up to 5 days, though the marshmallow topping tastes best if eaten within the first couple of days.
Freezing
You can freeze these bars wrapped tightly in plastic wrap and then foil for up to 2 months. Thaw them overnight in the fridge before serving, but keep in mind the marshmallow topping might lose some texture when frozen.
Reheating
If you want to warm them up, pop a bar or two in the microwave for about 15–20 seconds. Avoid heating too long to keep the marshmallow topping soft and the filling creamy without melting it all away.
FAQs
-
Can I use canned sweet potato puree instead of fresh?
While you can substitute canned sweet potato puree in a pinch, fresh sweet potatoes provide a superior flavor and creamier texture that really make these bars stand out. If you do use canned, make sure to drain off any excess liquid to avoid a soggy filling.
-
Is there a way to make the marshmallow topping without egg whites?
Yes! You can use store-bought marshmallow fluff and spread it over the filling, then toast lightly under the broiler. Alternatively, a vegan marshmallow recipe or coconut whipped cream can offer a similar fun and fluffy finish.
-
How can I tell when the sweet potato filling is done baking?
The filling should be mostly set with just a slight wobble in the center when you gently shake the pan. Overbaking will dry out the custard, so it’s best to err on the side of a little undercooked since it firms up as it cools.
-
Can I make Sweet Potato Pie Bars Recipe ahead of time?
Absolutely! You can prepare everything up to and including baking the sweet potato layer a day in advance. Add the marshmallow topping and toast just before serving to keep it fresh and fluffy.
Final Thoughts
This Sweet Potato Pie Bars Recipe is pure comfort wrapped in a festive package, perfect for sharing with loved ones or savoring solo during a quiet moment.

- 1/2 teaspoon fine sea salt
- 12 tablespoons unsalted butter, melted (169 grams)
Filling
- 2 cups fresh sweet potato puree (16 ounces or 454 grams)
- 1/4 cup granulated sugar (50 grams)
- 3 large eggs
- 1 1/2 cups whole milk (356 grams)
- 1/2 cup heavy cream (119 grams)
- 1 tablespoon bourbon (or 1 teaspoon vanilla extract)
- 1 teaspoon fine sea salt
- 1 1/2 teaspoons ground cinnamon
- 1/2 teaspoon ground ginger
- 1/4 teaspoon ground cloves
Topping
- 2 large egg whites
- 1/4 teaspoon cream of tartar
- 3/4 cup granulated sugar (150 grams)
- 1/2 cup light corn syrup (120 grams)
- 1/4 cup water
- 1/4 teaspoon fine sea salt
- 1 1/2 teaspoons vanilla extract
Instructions
- Prepare the crust: Preheat your oven to 350°F (175°C). Line an 8×8-inch metal baking pan with foil, leaving an overhang for easy removal. Place the graham crackers, sugar, and salt in a food processor and pulse until finely ground. Add the melted butter and pulse again until the mixture is evenly moistened. Press this mixture firmly into the bottom of the prepared pan. Bake in the oven for 10 minutes, then set aside on a cooling rack to cool completely while maintaining the oven temperature.
- Make the filling: In a large mixing bowl, combine the fresh sweet potato puree, sugar, eggs, whole milk, heavy cream, bourbon or vanilla, salt, cinnamon, ginger, and cloves. Beat with an electric mixer until everything is well combined and smooth. Pour the filling over the cooled graham cracker crust and return the pan to the oven. Bake for 40 minutes, or until the filling is set but slightly wobbly in the center. Remove from oven and let cool to room temperature.
- Prepare the marshmallow topping: Fit an electric mixer with the whisk attachment and beat the egg whites and cream of tartar together until soft peaks form. Meanwhile, combine sugar, corn syrup, water, and salt in a small heavy-bottomed saucepan over medium-high heat. Bring to a boil and cook until the syrup reaches exactly 240°F (soft-ball stage) on a candy thermometer. Immediately remove from heat.
- Combine syrup with egg whites: Turn the mixer to low speed and slowly drizzle the hot syrup into the egg whites in a thin, steady stream. Increase the mixer speed to medium-high and continue beating until the mixture is thick, glossy, and resembles marshmallow fluff, about 7 minutes. Add the vanilla extract and beat to incorporate.
- Assemble and toast topping: Spread the marshmallow topping evenly over the sweet potato filling. Use a kitchen torch to gently toast the marshmallow layer until lightly golden. Alternatively, place the pan under a preheated broiler for about 1 minute, watching closely to prevent burning.
- Chill and serve: Refrigerate the bars for at least 1 hour to set before cutting into squares. Store leftovers in an airtight container in the refrigerator for up to 5 days, though they are best enjoyed fresh.
Notes
- Use fresh sweet potato puree rather than canned for the best texture and flavor.
- Maintain careful attention when using the broiler to toast the marshmallow topping to avoid burning.
- The bourbon in the filling can be substituted with vanilla extract for a non-alcoholic version.
- Bars are best served within a few days, as the marshmallow topping may lose its texture over time.
