Granulated Sugar (Crust) – Adds sweetness; adjust according to personal preference.
Unsalted Butter – Binds the crust and enhances flavor; always use unsalted to control saltiness.

Step‑by‑Step Instructions for Sweet Potato Pie Bars

Step 1: Preheat and Prepare Your Pan
Begin by preheating your oven to 350°F (175°C). Meanwhile, take an 8×8-inch metal baking pan and line it with aluminum foil, allowing some overhang for easy removal later. This will ensure your Sweet Potato Pie Bars come out smoothly and maintain their shape.

Step 2: Make the Graham Cracker Crust
In a food processor, combine graham crackers, sugar, and a pinch of salt, processing until fine crumbs form. Next, melt unsalted butter and pour it into the crumb mixture, blending until thoroughly combined. Press this mixture firmly and evenly into the bottom of your prepared pan, creating a solid base for the bars.

Step 3: Bake the Crust
Place the crust in the preheated oven and bake for about 10 minutes, until it is golden and fragrant. Once done, remove the pan and let the crust cool completely on a wire rack. This cooling step is crucial to ensure your sweet potato filling doesn’t become too soggy.

Step 4: Prepare the Sweet Potato Filling
In a large mixing bowl, add the sweet potato purée, sugar, eggs, milk, heavy cream, bourbon or vanilla extract, sea salt, and the spice blend. Beat with an electric mixer until the filling is smooth and well combined, about 2-3 minutes. This creamy mixture will be the heart of your Sweet Potato Pie Bars.

Step 5: Bake the Filling
Pour the sweet potato filling evenly over the cooled crust in the baking pan. Bake in the preheated oven for approximately 40 minutes, or until the filling is just set and a toothpick inserted in the center comes out clean. It should have a slight jiggle when ready to come out.

Step 6: Prepare the Marshmallow Topping
While the filling bakes, prepare the marshmallow topping. In a large bowl, beat the egg whites with cream of tartar until soft peaks form, about 3-4 minutes. In a saucepan, combine sugar, corn syrup, water, and a pinch of salt; bring to a boil over medium heat until it reaches 240°F (115°C).

Step 7: Combine and Whip
Once the syrup reaches the desired temperature, gradually drizzle it into the whipped egg whites while continuing to beat on high speed. Whip the mixture until it thickens and becomes glossy, which should take another 5-6 minutes. This dreamy mixture will top your Sweet Potato Pie Bars beautifully.

Step 8: Assemble and Toast
Spread the marshmallow topping generously over the cooled sweet potato layer in the pan. For a delightful finish, use a kitchen torch to toast the top until golden, or broil for about 1 minute—watch closely to avoid burning. This adds a luscious caramelized flavor to your bars.

Step 9: Cool and Slice
Allow the assembled Sweet Potato Pie Bars to cool at room temperature for about 30 minutes. Then, refrigerate for at least 1 hour to firm up. Once chilled, lift the bars from the pan using the foil overhang, slice into squares, and prepare for serving. Enjoy this delightful fall treat!

How to Store and Freeze Sweet Potato Pie Bars

Room Temperature: Best consumed fresh, but can be kept at room temperature for up to 2 hours if serving at a gathering.

Make Ahead Options

These Sweet Potato Pie Bars are an excellent choice for busy home cooks looking to save time during the holiday hustle! You can prepare the graham cracker crust and sweet potato filling up to 24 hours in advance. Simply bake the crust and let it cool completely before storing it in an airtight container. The sweet potato filling can be mixed and stored in the refrigerator until it’s time to bake. When ready to serve, pour the filling over the crust and bake as directed. Finally, prepare the marshmallow topping while the bars are cooling to ensure a perfectly fluffy texture. With these make-ahead tips, you’ll have a stress-free dessert ready to impress your guests!

Expert Tips for Sweet Potato Pie Bars

Crust Consistency: Ensure the graham cracker crust is pressed firmly into the pan to avoid crumbling when sliced. Use a flat object for even pressure.
Avoid Canned Sweet Potatoes: Fresh sweet potato purée enhances texture and flavor significantly. Opt for fresh sweet potatoes for the best results.
Monitor Baking Time: Keep an eye on the sweet potato filling while baking; overbaking can lead to a dry texture. It should be set but still slightly jiggly in the center.
Whip Egg Whites Properly: For a fluffy marshmallow topping, ensure the egg whites are at room temperature and whipped to soft peaks before adding the sugar syrup.
Perfect Broiling: When toasting the marshmallow topping, watch carefully to prevent burning. Broil for just 1 minute, or use a kitchen torch to achieve that golden finish.
Storage Tip: Store leftover Sweet Potato Pie Bars in an airtight container in the refrigerator for up to 5 days. Enjoy them chilled for a refreshing treat!
