What’s in the Bowl

• Graham cracker crumbs – the base layer that creates a crunchy, buttery crust
• Unsalted butter – melted, to bind the crust and add richness
• Brown sugar – for sweetness and a subtle molasses flavor
• Pumpkin puree – the star ingredient bringing moistness and seasonal flavor
• Pumpkin pie spice – a fragrant blend of cinnamon, nutmeg, ginger, and cloves
• All-purpose flour – to give structure to the bars
• Baking powder – a leavening agent to keep the bars tender
• Granulated sugar – for balanced sweetness
• Egg – to bind the ingredients together
• Vanilla extract – for a hint of warmth and depth
• Chocolate chips – semi-sweet or milk for melty, chocolatey goodness
• Marshmallows – mini or chopped large marshmallows for gooey topping

Tools & Equipment Needed

• 8×8-inch baking pan – perfect size for these bars to bake evenly
• Mixing bowls – separate bowls for wet and dry ingredients make combining easier
• Measuring cups and spoons – for accurate ingredient portions
• Spatula – to fold ingredients gently and spread the batter
• Whisk – to blend wet ingredients smoothly
• Cooling rack – to cool the bars properly without sogginess

Build Pumpkin Spice S’mores Bars Step by Step

Step 1: Prepare the Crust

Preheat your oven to 350°F (175°C). In a medium bowl, combine the graham cracker crumbs, melted butter, and brown sugar. Stir until the mixture resembles wet sand. Press this mixture firmly into the bottom of your greased 8×8-inch baking pan, creating an even crust layer. Bake for 8-10 minutes until set and fragrant.

Step 2: Mix the Pumpkin Batter

While the crust bakes, whisk together the pumpkin puree, egg, granulated sugar, and vanilla extract in a large bowl. In a separate bowl, sift together the flour, baking powder, and pumpkin pie spice. Gradually add the dry ingredients to the wet mixture, stirring until just combined. Avoid overmixing to keep the bars tender.

Step 3: Assemble the Bars

Once the crust is slightly cooled, spread half of the pumpkin batter evenly over the crust. Sprinkle a generous layer of chocolate chips over the batter. Then, carefully spread the remaining pumpkin batter on top. Top everything with marshmallows, pressing them lightly into the batter.

Step 4: Bake to Perfection

Bake the bars for 25-30 minutes, or until the marshmallows are golden and the pumpkin batter is set around the edges but still soft in the center. Keep an eye on the marshmallows; you may want to switch to the broil setting for the last 1-2 minutes for a perfectly toasted top.

Step 5: Cool and Slice

Allow the bars to cool completely in the pan on a cooling rack. This helps them set and makes slicing easier. Once cooled, cut into squares and serve.

Season-by-Season Upgrades

• Fall: Add chopped pecans or walnuts to the batter for extra crunch and a nutty flavor.
• Winter: Drizzle warm caramel sauce over the bars for a festive touch.
• Spring: Incorporate a handful of dried cranberries or chopped dried apricots for a tart contrast.
• Summer: Use white chocolate chips and sprinkle toasted coconut flakes on top for a tropical twist.

Notes on Ingredients

• Pumpkin puree: Use pure pumpkin, not pumpkin pie filling, for the best texture and flavor.
• Marshmallows: Mini marshmallows work best for even melting, but chopped large marshmallows create gooey pockets.
• Chocolate chips: Semi-sweet chocolate pairs well with pumpkin spice, but feel free to use milk or dark chocolate based on preference.
• Butter: Unsalted butter lets you control the salt content, but salted butter can be used if preferred.

Freezer-Friendly Notes

These Pumpkin Spice S’mores Bars freeze beautifully, making them an excellent make-ahead treat. After baking and cooling completely, wrap individual bars tightly in plastic wrap and store them in an airtight container or freezer bag. They can be kept in the freezer for up to 3 months.

When ready to enjoy, thaw bars at room temperature or warm them gently in the microwave for 15-20 seconds to revive that gooey marshmallow texture.

Pumpkin Spice S’mores Bars FAQs

Can I use canned pumpkin pie filling instead of pumpkin puree?

It’s best to use plain pumpkin puree because canned pumpkin pie filling contains added sugars and spices that can alter the sweetness and flavor balance of the bars.

What’s the best way to toast the marshmallows evenly?

Baking the bars in a preheated oven will toast the marshmallows nicely, but if you want a more golden top, switch to the broiler for the last 1-2 minutes. Watch closely to prevent burning.

Can I substitute the graham cracker crust with something else?

Yes! You can use crushed digestive biscuits or even a mixture of crushed cookies and nuts for a unique twist. Just make sure to adjust the butter quantity to bind the crust properly.

How do I store leftover Pumpkin Spice S’mores Bars?

Store leftovers in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate for up to a week or freeze as described above.
