Last weekend, I dug out my favorite autumn-themed apron, cranked up a pumpkin spice latte playlist, and got to work on these bars—my kitchen smelled like the coziest café in town. The graham cracker crust crunched under my fork, giving way to a velvety pumpkin layer that held just the right balance of brown sugar sweetness and classic pumpkin pie spice warmth. Then, when the marshmallows puffed up in the oven and the milk chocolate chips began to melt, I couldn’t resist grabbing a warm square before they’d even cooled. This recipe is a true beginner-friendly dessert gem: no fancy equipment required, just a 9×13 pan, a few bowls, and heaps of enthusiasm. Whether you’re planning a Halloween party, a fall potluck, or a quiet night curled up with a movie, these bars deliver that sweet nostalgia we all crave—without the campfire.
KEY INGREDIENTS IN PUMPKIN S’MORES BARS
Before we dive into the step-by-step magic, let’s talk about the simple ingredients that make these bars shine. Each item brings its own character and purpose, building layers of flavor and texture that will have everyone coming back for seconds.
- Graham cracker crumbs
These finely crushed crackers form the crunchy base of our bars, giving each bite that classic s’mores foundation. They also absorb the butter and sugar, ensuring a sturdy crust that won’t crumble under the pumpkin layer.
- Unsalted butter
Melted and mixed in with the crumbs, butter adds richness and moisture. It binds the crust together and provides a silky mouthfeel that balances the spices in the filling.
- Granulated sugar
A touch of sugar in the crust gives a gentle sweetness that complements the pumpkin filling. It also helps to caramelize the graham cracker base, enhancing its golden color and crispness.
- Ground cinnamon
This warming spice lends a subtle, fragrant note to the crust that ties in beautifully with the pumpkin pie spice in the filling.
- Canned pumpkin puree
The star of the show, pumpkin puree delivers that smooth, creamy body we associate with fall desserts. It’s packed with natural sweetness and moisture, making the pumpkin layer lush and velvety.
- Brown sugar
With its molasses undertones, brown sugar deepens the flavor of the pumpkin filling and contributes a hint of caramel richness.
- Vanilla extract
Vanilla adds a fragrant backdrop that elevates both the pumpkin and chocolate flavors, weaving them together in perfect harmony.
- Pumpkin pie spice
A proprietary blend of cinnamon, nutmeg, ginger, and cloves, this spice mix gives the filling a true autumnal character and an irresistible aroma.
- Large eggs
Eggs act as the binding agent in the pumpkin layer, creating structure and ensuring that the filling sets up just right without turning soggy.
- Mini marshmallows
Scatter these on top for that classic s’mores moment. As they toast, mini marshmallows become light, pillowy, and slightly caramelized, adding a dreamy texture.
- Milk chocolate chips
Sprinkled over the warm marshmallows, these chips melt into gooey pockets of sweetness, completing the ultimate chocolate-marshmallow combo.
HOW TO MAKE PUMPKIN S’MORES BARS
Let’s walk through how to transform these pantry staples into a show-stopping autumn dessert. Follow each step closely, and you’ll be rewarded with perfectly layered bars that highlight every flavor—from the spicy pumpkin to the decadent chocolate-marshmallow topping.
1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish or line it with parchment paper for easy removal of the bars once they’re set.
2. In a medium bowl, combine the graham cracker crumbs, melted butter, granulated sugar, and ground cinnamon. Mix thoroughly until the crumbs are evenly moistened, then press the mixture firmly into the bottom of the prepared dish to form an even crust.
3. In a large bowl, whisk together the pumpkin puree, brown sugar, vanilla extract, pumpkin pie spice, and eggs. Continue until the mixture is completely smooth and there are no streaks of sugar or spice.
4. Pour the pumpkin filling over the graham cracker crust, then use a spatula to spread it into an even layer, ensuring full coverage from edge to edge.
5. Bake in the center rack of the preheated oven for 20–25 minutes, or until the pumpkin layer is set and doesn’t jiggle when you gently shake the pan.
6. Carefully remove the dish from the oven and sprinkle the mini marshmallows evenly across the top of the warm pumpkin layer.
7. Return the pan to the oven and bake for another 5–7 minutes, keeping an eye on the marshmallows as they puff and turn a light golden brown.
8. Once toasted, remove from the oven and immediately sprinkle the milk chocolate chips over the hot marshmallows. Allow the residual heat to melt the chips into smooth, gooey rivers of chocolate.
9. Let the bars cool in the dish on a wire rack for about 30 minutes, then refrigerate for at least 1 hour to firm up for easy slicing.
10. Cut into bars and serve, delighting in the layered combination of pumpkin, marshmallow, and chocolate in every bite.
SERVING SUGGESTIONS FOR PUMPKIN S’MORES BARS
When it’s time to share these Pumpkin S’mores Bars, presentation and pairing can take them from “yum” to “wow.” Whether you’re hosting a fall gathering or simply treating yourself, these ideas will ensure your dessert steals the show.
- Warm with a Scoop of Ice Cream
Serve slices while still slightly warm, accompanied by a scoop of vanilla or cinnamon ice cream. The contrast between the chilled ice cream and the still-warm marshmallow makes every bite feel indulgent.
- Drizzle with Caramel or Chocolate Sauce
Elevate the sweetness factor by lightly drizzling warmed caramel or chocolate sauce over each bar. This adds an extra layer of gooey richness and makes them look beautifully gourmet.
- Garnish with Toasted Nuts
Sprinkle roughly chopped pecans or walnuts on top just before serving. The crunch adds a delightful textural contrast and nutty flavor that complements both pumpkin and chocolate.
- Create a Rustic Dessert Platter
Arrange bars on a wooden board with small bowls of extra mini marshmallows, chocolate chips, and graham crackers. Guests can customize their own bite-sized s’mores creations for interactive fun.
HOW TO STORE PUMPKIN S’MORES BARS
Keeping these bars fresh ensures you can enjoy their layered goodness throughout the week. With a bit of care, you’ll maintain the perfect balance of creamy pumpkin filling and melty marshmallow topping.
First, allow the bars to cool completely and chill in the refrigerator so the layers set firmly. Then:
- Refrigerate in an Airtight Container
Place the cooled bars in a single layer or separate layers with parchment paper. Seal them in an airtight container to prevent drying out and to keep the marshmallows soft. They’ll stay fresh for up to 5 days.
- Freeze for Longer Storage
To freeze, wrap individual bars in plastic wrap, then place in a freezer-safe bag or container. This double-wrapping prevents freezer burn. Thaw in the fridge overnight before serving; they’ll keep for up to 2 months.
- Avoid Room-Temperature Storage
Because of the pumpkin filling, these bars are best stored cold. Leaving them out for more than a few hours can soften the crust and affect the texture of the filling.
- Layer with Parchment Paper
If stacking bars in a container, place a sheet of parchment paper between layers. This prevents them from sticking together and makes serving easier.
