Sweet Potato Pie Bars Ingredients

Graham Crackers – Structure the crust and provide a sweet crunch; you can substitute with digestive biscuits for a unique flavor.
Granulated Sugar – Adds sweetness; feel free to reduce or omit for a less sweet crust.

Unsalted Butter – Binds the crust ingredients; coconut oil is a great dairy-free substitute.

For the Filling

Fresh Sweet Potato Puree – Provides a smooth and creamy filling; avoid canned options for the best taste.
Eggs – Essential for binding the filling; flax eggs can be substituted for a vegan option.
Whole Milk – Adds creaminess; almond milk works as a dairy-free alternative.

Bourbon (or Vanilla Extract) – Flavors the filling beautifully; you may omit for a non-alcoholic version.
Ground Spices (Cinnamon, Ginger, Cloves) – These enhance the fall flavors; adjust to your personal taste preference.

For the Marshmallow Topping

Egg Whites – Create the fluffy marshmallow topping; ensure they achieve soft peaks before adding syrup.

Step‑by‑Step Instructions for Sweet Potato Pie Bars

Step 1: Prepare the Crust
Preheat your oven to 350°F and grease an 8×8-inch metal pan with foil for easy removal. In a food processor, pulse together graham crackers, granulated sugar, fine sea salt, and melted unsalted butter until combined. Press this mixture firmly into the bottom of the pan, creating an even layer. Bake for 10 minutes until set and slightly golden.

Step 2: Blend the Filling
In a large mixing bowl, combine fresh sweet potato puree, granulated sugar, eggs, whole milk, heavy cream, bourbon, fine sea salt, and ground spices. Beat this mixture until smooth and creamy, ensuring all ingredients are well incorporated. Once your crust has cooled, pour the sweet potato filling over it, then bake for 40 minutes. The filling should be set with a slight wobble in the center.

Step 3: Make the Marshmallow Topping
While the filling cools, prepare the marshmallow topping. In a clean mixing bowl, beat egg whites and cream of tartar until soft peaks form. In a saucepan, combine sugar, corn syrup, water, and a pinch of salt. Bring this mixture to a simmer and cook until it reaches 240°F, using a candy thermometer to check the temperature.

Step 4: Combine and Whip
Gradually drizzle the hot syrup into the whipped egg whites while continuing to beat at medium speed. This should take about 2 minutes. Keep whipping until the mixture thickens and becomes glossy, forming stiff peaks. Finally, gently fold in vanilla extract, ensuring it’s evenly distributed within the marshmallow.

Step 5: Finish the Bars
Once the sweet potato layer is completely cool, spread the marshmallow topping evenly across it, creating a beautiful layer. To achieve a toasted finish, use a kitchen torch to caramelize the marshmallow, or place it under the broiler for a minute or two, watching closely to prevent burning. Once toasted, allow the bars to cool in the refrigerator for at least one hour.

Step 6: Serve and Enjoy
After chilling, carefully lift the bars out of the pan using the foil edges. Cut into squares for serving. These Sweet Potato Pie Bars are now ready to be enjoyed! Their delightful combination of creamy filling, buttery crust, and fluffy marshmallow topping will surely impress your family and friends at your next gathering.

Expert Tips for Sweet Potato Pie Bars

Crust Consistency: Ensure your graham cracker crust is tightly packed. Press it down with a measuring cup for a firm base that won’t crumble.
Avoid Canned Sweet Potatoes: For the best flavor and texture, use fresh sweet potato puree instead of canned. The difference is truly remarkable!
Pay Attention While Broiling: When toasting the marshmallow topping under the broiler, keep a close eye. It can burn quickly and ruin your beautiful dessert.
Perfect Marshmallow Texture: Don’t skip the corn syrup in the marshmallow topping. It’s crucial for achieving that smooth, fluffy texture, so be sure to include it.
Cool Completely: Allow the sweet potato filling to cool completely before adding the marshmallow topping to avoid melting and messiness.
Use Foil for Easy Removal: Line your pan with foil instead of parchment paper; it makes for easier removal and avoids any flammable issues during high-heat toasting.

Make Ahead Options

Preparing your Sweet Potato Pie Bars ahead of time is a fantastic way to save time and reduce stress during busy gatherings! You can make the graham cracker crust up to 3 days in advance and store it in an airtight container at room temperature to maintain its crunch. Additionally, the sweet potato filling can be prepared up to 24 hours ahead; simply refrigerate it in an airtight container until you’re ready to bake. When you’re set to finish the bars, pour the filling over the crust and bake as instructed. The marshmallow topping should ideally be whipped fresh right before serving for the best texture, giving your Sweet Potato Pie Bars that delightful, fluffy finish just in time for your guests to enjoy!

Sweet Potato Pie Bars Recipe FAQs

What type of sweet potatoes should I use for the filling?
Absolutely! I recommend using fresh sweet potatoes for this recipe. Look for firm, blemish-free sweet potatoes without dark spots all over. These yield a richer flavor and smoother texture compared to canned options, which can be watery and less flavorful.

How should I store leftover Sweet Potato Pie Bars?
For the best taste, store your Sweet Potato Pie Bars in an airtight container in the refrigerator for up to 5 days. This keeps the rich filling and fluffy marshmallow topping fresh and delightful. I often make them ahead of time so they’re ready for gatherings!

Can I freeze Sweet Potato Pie Bars?
Yes, indeed! To freeze, wrap each bar tightly in plastic wrap and then place them in a freezer-safe container. They’ll maintain their delicious flavor for up to 2 months. When you’re ready to enjoy them, simply thaw in the fridge overnight and, if desired, microwave for 10-15 seconds to serve warm.

What if my marshmallow topping doesn’t set correctly?
Very! If your marshmallow topping is too runny, it could be due to not beating the egg whites to soft peaks properly or not reaching the right temperature (240°F) during syrup cooking. If this happens again, try reheating the marshmallow mixture gently while continuously beating until it thickens. Also, ensure to add the corn syrup for the right consistency.

Are there any dietary considerations for Sweet Potato Pie Bars?
Absolutely, if you’re be mindful of allergies or dietary restrictions! To make a dairy-free version, substitute whole milk and heavy cream with almond milk and coconut cream, respectively. Additionally, you can use flax eggs in place of regular eggs for a vegan option without losing that delightful texture!
