Sweet Potato Pie Bars Ingredients

For the Crust
• Graham Crackers – Structure is key; for a richer flavor, try digestive biscuits or Biscoff cookies as substitutes.
• Granulated Sugar – Adds sweetness; feel free to reduce the amount in the sweet potato filling for a less sugary bite.
• Fine Sea Salt – Enhances flavor; table salt can be used as a substitute, just avoid anything coarse for consistency.
• Unsalted Butter – Provides binding and richness; make sure it’s melted for easy mixing.

For the Filling
• Fresh Sweet Potato Puree – The main component that gives these bars their signature flavor; fresh is best for a creamy texture.
• Large Eggs – Three eggs provide structure and stability; don’t skip them for proper binding.
• Whole Milk – Adds moisture; almond milk can work as a dairy-free alternative.
• Heavy Cream – Ensures creaminess; you can substitute with whipping cream if needed.
• Bourbon (or Vanilla Extract) – Infuses flavor; bourbon brings depth, but vanilla is a tasty non-alcoholic substitute.
• Ground Spices (Cinnamon, Ginger, Cloves) – Creates a rich flavor profile; adjust these spices based on your taste preferences.

For the Marshmallow Topping
• Egg Whites – Two egg whites, beaten to soft peaks, give the marshmallow its airy texture.
• Cream of Tartar – Stabilizes the egg whites for a fluffy topping; don’t omit this essential ingredient.
• Light Corn Syrup – Prevents sugar crystallization, yielding a smooth marshmallow texture; alternatives should be tested for best results.
• Water – Used for dissolving sugar in your marshmallow mix; the key to getting it just right.

These Sweet Potato Pie Bars are not just a delight for your taste buds but an experience to share. With each bite, you’re sure to bring the spirit of fall into your home. Enjoy creating these delicious treats!

Step‑by‑Step Instructions for Sweet Potato Pie Bars

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While that’s warming up, grab an 8×8-inch metal baking pan and line it with foil, allowing some overhang on the sides for easy removal later. This will help make your Sweet Potato Pie Bars easy to lift out once they are baked.

Step 2: Prepare the Crust
In a food processor, pulse together the graham crackers, granulated sugar, and fine sea salt until they become fine crumbs. Next, pour in the melted unsalted butter and blend until the mixture resembles wet sand. Press this mixture evenly into the bottom of your prepared pan and bake for 10 minutes, or until slightly golden. Allow it to cool completely.

Step 3: Make the Sweet Potato Filling
In a large mixing bowl, combine fresh sweet potato puree, large eggs, whole milk, heavy cream, bourbon (or vanilla extract), and the ground spices: cinnamon, ginger, and cloves. Blend everything together until the filling is smooth and creamy. Pour this mixture over your cooled crust and spread it evenly, then bake for approximately 40 minutes until the filling is set with a slight wobble in the center.

Step 4: Cool the Bars
Once the filling is baked, remove them from the oven and let your Sweet Potato Pie Bars cool to room temperature in the pan. This will help the filling firm up and make cutting easier later. Take your time—the cooling process may take about an hour.

Step 5: Prepare the Marshmallow Topping
While the bars cool, you can prepare the topping. In a bowl, beat the egg whites and cream of tartar until soft peaks form. In a saucepan, combine granulated sugar, light corn syrup, water, and a pinch of salt. Bring this mixture to a boil and cook until it reaches 240°F (115°C), then slowly drizzle it into the beaten egg whites while continuing to beat until the mixture becomes thick and glossy.

Step 6: Assemble the Bars
Spread the marshmallow topping evenly over the cooled sweet potato layer, creating a fluffy layer on top. To finish, use a kitchen torch or a broiler to lightly toast the marshmallow until golden brown and bubbly. Be sure to keep a close eye on this step as it can burn quickly!

Step 7: Chill and Slice
Finally, place the Sweet Potato Pie Bars in the refrigerator for at least 1 hour. This will help the marshmallow topping set perfectly. Once chilled, lift the bars out using the foil overhang, slice them into squares, and serve!

Make Ahead Options

These Sweet Potato Pie Bars are a lifesaver for busy home cooks looking to save time! You can prepare the graham cracker crust and the sweet potato filling up to 24 hours in advance. Simply follow the recipe steps up to baking the filling, then cover it tightly with plastic wrap and refrigerate. The marshmallow topping should be made fresh on the day you plan to serve them for the best texture. When you’re ready to serve, just toast the marshmallow topping, let it chill for an hour, and you’ll be enjoying a delicious fall treat with minimal effort. This way, you can savor both the flavors and the moments with your loved ones!

Storage Tips for Sweet Potato Pie Bars

Fridge: Store your Sweet Potato Pie Bars covered in an airtight container in the refrigerator for up to 5 days. This keeps them fresh, though flavors may meld over time.

Freezer: To freeze, wrap the bars tightly in plastic wrap and then in aluminum foil. They can be frozen for up to 3 months—just thaw in the fridge overnight before serving.

Reheating: If you prefer them warm, reheat bars in the oven at 350°F for about 10-15 minutes. This will revive that delightful texture and flavor.

Serving: For the best experience, enjoy them fresh or shortly after slicing. The marshmallow topping may weep if stored too long, so serve soon after chilling!

Expert Tips for Sweet Potato Pie Bars

Sweet Potato Pie Bars Recipe FAQs

How do I select the best sweet potatoes for this recipe?
Absolutely! Look for medium-sized sweet potatoes that feel firm to the touch with smooth skin. Avoid those with dark spots or soft areas, as they may be overripe. Fresh sweet potatoes typically have a slightly sweet smell, indicating they are ripe and ready to use. You’ll achieve the best flavor and texture for your Sweet Potato Pie Bars when you start with high-quality ingredients!

How should I store leftover Sweet Potato Pie Bars?
To keep your Sweet Potato Pie Bars fresh, store them covered in an airtight container in the refrigerator for up to 5 days. This helps maintain their texture, but keep in mind that flavors may meld over time. Best enjoyed within the first few days for that delightful burst of freshness!

Can I freeze Sweet Potato Pie Bars, and if so, how?
Certainly! To freeze your Sweet Potato Pie Bars, first wrap them tightly in plastic wrap, ensuring no air pockets are left. Next, cover them with aluminum foil for added protection against freezer burn. They can be frozen for up to 3 months. When you’re ready to enjoy, simply thaw them in the refrigerator overnight before slicing and serving.

Why did my marshmallow topping deflate?
Very! If your marshmallow topping deflated, it could be due to a few reasons. First, ensure you whip the egg whites to stiff peaks before adding the hot sugar mixture. Also, make sure the sugar syrup reaches the proper temperature of 240°F (115°C)—be careful not to undercook it. Lastly, avoid overmixing once you’ve added the syrup; you want to maintain volume. If you follow these steps, your topping should turn out fluffy and light!

Is there a safe alternative for corn syrup in the marshmallow topping?
Using corn syrup is crucial for achieving the right consistency in your marshmallow topping. However, if you’re looking for an alternative, you can try using golden syrup. Keep in mind that the flavor may differ slightly, and it’s essential to test out this substitution as results can vary. I recommend sticking with corn syrup for the best outcome in your Sweet Potato Pie Bars!

Are there any dietary considerations I should keep in mind for this recipe?
Absolutely! For those with dietary restrictions, using almond milk is a fantastic dairy-free option. You may also substitute the eggs with a suitable egg replacement if you’re vegan, but this will require some trial and error for the best texture. If you’re serving to guests with allergies, be cautious with the graham crackers, as some brands might contain gluten or nuts. Always check labels to ensure all ingredients meet their dietary needs!
