For the Marshmallow Topping
• Large Egg Whites – Essential for creating a fluffy marshmallow topping; must be whipped until soft peaks form.

Step‑by‑Step Instructions for Sweet Potato Pie Bars

Step 1: Preheat and Prepare the Pan
Begin by preheating your oven to 350°F (175°C). While the oven warms up, take an 8×8-inch metal baking pan and line it with foil, leaving some overhang on the sides. This will make it easy to lift the Sweet Potato Pie Bars out once baked. Set the pan aside as you prepare your buttery graham cracker crust.

Step 2: Make the Graham Cracker Crust
In a food processor, blend together graham crackers, sugar, and a pinch of sea salt until finely crushed. Pour in the melted unsalted butter, mixing until the texture resembles wet sand. Press this mixture firmly into the bottom of your prepared pan. Place the pan in the oven and bake for 10 minutes, then allow it to cool completely.

Step 3: Prepare the Sweet Potato Filling
For the filling, combine fresh sweet potato puree, large eggs, whole milk, heavy cream, bourbon (or vanilla), fine sea salt, and your choice of ground spices in a blender. Blend until all ingredients are thoroughly combined and the mixture is smooth and creamy. Once the graham cracker crust has cooled, pour the sweet potato filling over the crust, spreading it evenly.

Step 4: Bake Until Set
Slide the baking pan into the still-heated oven and bake the Sweet Potato Pie Bars for about 40 minutes. You’ll know they’re done when the edges look set but the center retains a slight wobble—this ensures a creamy, delicious texture. Once baked, remove the pan from the oven and allow it cool at room temperature for at least 30 minutes.

Step 5: Prepare the Marshmallow Topping
To make the marshmallow topping, start by beating large egg whites and cream of tartar in a clean mixing bowl until soft peaks form. In a saucepan, combine light corn syrup, sugar, water, and a pinch of salt, and cook over medium heat until it reaches 240°F (115°C). Carefully drizzle this hot syrup into the egg whites while continuing to whip until the marshmallow mixture is fluffy and glossy.

Step 6: Spread and Toast the Marshmallow
Once your marshmallow topping is ready, spread it generously over the cooled sweet potato filling, ensuring even coverage. For the finishing touch, use a kitchen torch or place the bars under the broiler for 2-3 minutes, watching closely until the marshmallow is golden and toasted to perfection.

Step 7: Cool, Slice, and Serve
Finally, let the Sweet Potato Pie Bars cool for at least 1 hour at room temperature. This will help them set completely and make slicing easier. Once they are ready, lift the bars out of the pan using the foil overhang, cut them into squares, and serve them plain or drizzled with caramel sauce for an extra indulgence.

Make Ahead Options

Preparing Sweet Potato Pie Bars in advance is a fantastic way to save time during busy holidays! You can make the graham cracker crust and sweet potato filling up to 24 hours ahead of time. Simply prepare the crust, bake, and cool, then pour in the filling and store it in the refrigerator (covered) until you’re ready to bake. For the marshmallow topping, whip it up right before serving to maintain its light and fluffy texture. Toast the marshmallow just before serving for that freshly toasted flavor. By prepping ahead, you’ll find yourself enjoying the festivities without the last-minute rush while still delivering delicious, homemade Sweet Potato Pie Bars!

Expert Tips for Sweet Potato Pie Bars

Cool Before Slicing: Allow the bars to cool for at least 1 hour before slicing to ensure clean, neat cuts and make serving easier.

Sweet Potato Pie Bars Recipe FAQs

How do I select the perfect sweet potatoes for this recipe?
Absolutely! Look for fresh sweet potatoes that have smooth skin and are free of dark spots or blemishes. Heavier sweet potatoes will generally have a richer flavor and a creamier texture, which is what you need for this bar recipe. Aim for medium-sized sweet potatoes, around 2 to 3 inches in diameter, as they tend to have the best balance of sweetness and starchiness for pureeing.

What is the best way to store Sweet Potato Pie Bars?
To keep your Sweet Potato Pie Bars fresh, store them in an airtight container in the refrigerator for up to 5 days. This helps maintain their creamy filling and the integrity of the marshmallow topping. Keep in mind that they may lose a bit of crispness over time, so they are best enjoyed sooner rather than later.

Can I freeze Sweet Potato Pie Bars?
Yes! To freeze your Sweet Potato Pie Bars for future enjoyment, first, let them cool completely. Wrap each bar tightly in plastic wrap, and then in aluminum foil to prevent freezer burn. They can be frozen for up to 2 months! When you are ready to enjoy them, transfer them to the fridge for several hours or overnight to thaw. Reheat in an oven preheated to 350°F for a few minutes to restore their lovely fluffy texture.

What should I do if my marshmallow topping isn’t fluffy enough?
If your marshmallow topping doesn’t achieve the desired fluffiness, don’t fret! Make sure your egg whites are at room temperature before whipping them; it helps them achieve maximum volume. Additionally, be patient while gradually adding the hot sugar syrup to the whites. If needed, continue to beat the mixture for a few more minutes after adding the syrup, until you achieve soft peaks that hold their shape.

Are there any dietary considerations I should know about?
While these Sweet Potato Pie Bars are a delightful treat, keep in mind that they contain common allergens such as eggs, dairy (whole milk and heavy cream), and gluten (graham crackers). For non-dairy options, you can substitute whole milk with almond, coconut, or oat milk. If you have a gluten allergy, using gluten-free graham crackers or alternative crusts like almond flour is a great option!
