Ingredients You’ll Need

You’ll be amazed at how just a handful of simple, well-chosen ingredients can come together to create such an extraordinary treat. Each component plays a crucial role, from the buttery graham cracker crust to the spiced pumpkin layer, creating a symphony of textures and flavors.

1 cup unsalted butter, melted: This binds the crust and adds a smooth, rich flavor that’s essential for that buttery base.
2 cups graham cracker crumbs: The foundation of your s’mores taste, providing that crisp, slightly sweet crunch.
1/4 cup granulated sugar: Just enough sweetness to balance the crust without overpowering the pumpkin.
1/4 teaspoon salt: Enhances all the flavors and keeps the sweetness in check.
1 cup canned pumpkin puree: The star of the show, delivering moisture, earthiness, and that beautiful autumn hue.
1 cup sweetened condensed milk: Adds a luscious creaminess and natural sweetness to the pumpkin layer.
2 teaspoons pumpkin pie spice: This magical blend infuses those signature fall spices like cinnamon, nutmeg, and cloves.
1 teaspoon vanilla extract: Elevates every flavor with a subtle, aromatic sweet note.
1 large egg: Helps bind the pumpkin mixture and gives the bars their perfect texture.
2 cups semi-sweet chocolate chips: Melts into gooey pockets of chocolate that pair wonderfully with pumpkin.
2 cups mini marshmallows: The crowning glory, toasted golden on top for that classic s’mores finish.

How to Make Pumpkin S’mores Bars

Step 1: Prepare the Base

Start by preheating your oven to 350°F (175°C) and greasing a 9×13-inch baking pan. Mixing the melted butter, graham cracker crumbs, sugar, and salt creates a buttery, crisp crust that captures the essence of classic s’mores. Press it firmly into the baking pan to build a sturdy, flavorful foundation for your pumpkin layer.

Step 2: Whisk the Pumpkin Mixture

In a separate bowl, whisk together the creamy pumpkin puree, sweetened condensed milk, pumpkin pie spice, vanilla extract, and egg until the mixture is smooth and well combined. This fragrant blend is what elevates these bars beyond the ordinary, embodying all the smells and tastes that make pumpkin so beloved in fall desserts.

Step 3: Assemble the Layers

Pour the pumpkin mixture evenly over the prepared graham cracker crust, smoothing it out so every bite is packed with that spicy, creamy goodness. Then, sprinkle the semi-sweet chocolate chips evenly on top. This layer will melt into luscious pockets of chocolate, blending perfectly with the pumpkin and bringing a rich contrast.

Step 4: Bake and Add the Marshmallows

Bake your creation for about 15 minutes until the pumpkin layer begins to set. Remove from the oven and generously scatter the mini marshmallows over the top. These will toast to a beautiful golden brown during the final baking, offering that iconic toasted marshmallow flavor that defines s’mores.

Step 5: Final Bake and Cool

Return the pan to the oven for another 10 to 15 minutes, until the marshmallows are perfectly toasted and the edges appear set. Allow the bars to cool completely on a wire rack before cutting them into squares—this step ensures they hold together beautifully and each piece is as delicious as the first.

How to Serve Pumpkin S’mores Bars

Garnishes

For a touch of elegance and extra flavor, consider sprinkling a pinch of cinnamon or pumpkin spice on top just before serving. A drizzle of melted chocolate or a light dusting of powdered sugar can add an extra decorative and tasty element. These bars are already wonderfully indulgent, so simple garnishes work best.

Side Dishes

Serve Pumpkin S’mores Bars alongside a scoop of vanilla ice cream or a dollop of whipped cream for a classic pairing that cools the warm spices and adds creaminess. A hot cup of coffee, chai latte, or spiced cider is a perfect beverage companion that complements the dessert’s fall flavors beautifully.

Creative Ways to Present

Cut the bars into bite-sized squares and arrange them on a rustic wooden board for a cozy autumn gathering. For a party, pop some on decorative skewers alongside roasted marshmallows and cinnamon sticks to create a delightful fall s’mores platter. These bars also work wonderfully packaged in a pretty box or wrapped in parchment for gifting to friends and loved ones.

Make Ahead and Storage

Storing Leftovers

Once cooled, store your Pumpkin S’mores Bars in an airtight container at room temperature for up to three days. They remain moist and delicious, though the marshmallow topping might soften slightly over time, which some folks love even more — think gooey and comforting!

Freezing

If you want to keep these heavenly bars for longer, freeze them in a single layer on a baking sheet first, then transfer to a freezer-safe container or bag. They freeze beautifully for up to two months and make a fantastic grab-and-go treat when you’re craving a seasonal snack in the future.

Reheating

To enjoy them warm, simply thaw bars at room temperature and then pop them in a low oven (around 300°F or 150°C) for 5 to 7 minutes to revive the gooey marshmallows and melted chocolate. You can also microwave a single bar for about 15 seconds for an instant warm-up if you’re in a hurry.

FAQs

Can I use fresh pumpkin instead of canned?

Absolutely! If using fresh pumpkin, roast and puree it until smooth before measuring out one cup. This will provide a fresher flavor but keep the texture and moisture level similar to canned pumpkin.

What can I substitute for sweetened condensed milk?

If you don’t have sweetened condensed milk, you can use evaporated milk combined with extra sugar or try a sweetened coconut milk concentrate for a dairy-free twist, although it will slightly change the flavor profile.

Can I make Pumpkin S’mores Bars vegan?

Yes, with some ingredient swaps like using vegan butter, a flax egg instead of a regular egg, dairy-free chocolate chips, and marshmallows that are vegan-friendly, you can create a delicious plant-based version.

How do I prevent the marshmallows from burning?

Keep a close eye during the final baking stage, and if the marshmallows start to brown too quickly, you can loosely tent the pan with aluminum foil to prevent burning while allowing them to toast gently.

Can I add nuts to the recipe?

Of course! Chopped pecans or walnuts would add a lovely crunch and delicious earthy flavor that pairs well with pumpkin, chocolate, and marshmallows. Sprinkle them on top with the chocolate chips for the best distribution.

Final Thoughts

These Pumpkin S’mores Bars are truly a celebration of all things autumn and comfort food, perfectly capturing the playful spirit of traditional s’mores with a seasonal pumpkin twist. Once you try them, I promise they’ll become a beloved staple in your fall dessert repertoire. So go ahead and bake up a batch—you’ll be sharing joy, warmth, and smiles with every delectable square!

Instructions

Preheat and Prepare Pan: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan thoroughly and set it aside to get ready for the crust.
Make the Crust: In a mixing bowl, combine the melted unsalted butter, graham cracker crumbs, granulated sugar, and salt. Stir until well blended. Press this mixture firmly into the bottom of the prepared pan to create an even crust layer.
Mix Pumpkin Filling: In a separate bowl, whisk together the canned pumpkin puree, sweetened condensed milk, pumpkin pie spice, vanilla extract, and the large egg until the mixture is smooth and fully combined.
Assemble the Bars: Pour the pumpkin filling evenly over the graham cracker crust in the baking pan, spreading it to cover the surface completely.
Add Chocolate Chips: Sprinkle the semi-sweet chocolate chips evenly over the pumpkin layer to ensure every bite has chocolate goodness.
First Bake: Place the pan in the preheated oven and bake for about 15 minutes to set the pumpkin layer and slightly melt the chocolate chips.
Add Marshmallows: Remove the pan from the oven and scatter the mini marshmallows evenly over the top of the chocolate layer.
Final Bake and Toast: Return the pan to the oven and bake for an additional 10-15 minutes, or until the marshmallows are golden brown and the edges of the bars are set.
Cool and Serve: Allow the bars to cool completely in the pan on a wire rack. Once cool, cut into squares and serve for a delicious fall dessert treat.

Notes

Use full-fat canned pumpkin puree for the best flavor and texture.
If you prefer less sweetness, reduce the sugar in the crust slightly.
Keep an eye on the marshmallows while toasting to avoid burning.
Store leftover bars in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
These bars can be frozen for up to 2 months; thaw overnight in the refrigerator before serving.
