Living in Florida means fall looks a little different around here. September may be here, but the weather still feels like summer for a few more months. I've learned to embrace it, and honestly, some of my favorite recipe ideas have come from mixing those two seasons together. These s'mores pumpkin bars are a perfect example.

S'mores are one of my favorite summer treats, but once fall arrives, I start craving pumpkin. So I thought, why not combine the two? This way, I can enjoy a bit of both seasons in one dessert with a fun fall twist.

The base for these pumpkin bars actually came from my peanut butter s'mores blondies. I swapped the peanut butter for a full cup of pumpkin puree, and it made these bars soft and slightly cake-like.

Next, I sprinkled on chocolate chips and marshmallows and popped the pan under the broiler for a few minutes. One bite of the soft bars with golden marshmallows and melty chocolate, and I knew I had a winner.

Why You'll Love This Pumpkin S'mores Bar Recipe

The best of summer and fall. Pumpkin bars and s'mores topping might sound a little unexpected, but somehow they work SO well together!
That gooey s'mores topping. Chocolate chips and toasted golden marshmallows make these bars extra special. No campfire needed!
Perfect for sharing. A 9x13 pan makes plenty of bars for parties, potlucks, or just having dessert around for a few days. Although they tend to disappear pretty quickly!
Even better the next day. This dessert gets softer, and the flavors really come together if you let it sit overnight. Good luck waiting that long! LOL!

Ingredient Notes

Simple pantry ingredients and a bag of chocolate chips and marshmallows are all you need to make this fun fall recipe. Scroll down to the printable recipe card for the exact amounts.

Three pumpkin bars with s'mores toppings stacked on a white plate.

Unsalted Butter: Softened butter gives the bars a rich, tender base. Set it out about 30 minutes before baking, so it's soft.
Brown Sugar: Adds sweetness and a little caramel flavor.
Pumpkin Puree: Gives the bars a soft texture and delicious fall flavor. Be sure to use pure pumpkin puree, not pumpkin pie filling, which has added sugar and spices.
Large Eggs: Help bind everything together and add richness.
Vanilla Extract and Salt: Add flavor and balance out the sweetness.
Baking Powder: Gives the bars a little lift as they bake.
All-Purpose Flour: Provides structure. For the best results, spoon the flour into your measuring cup and level it off.
Cinnamon and Nutmeg: Add that warm fall flavor. You can also use pumpkin pie spice instead.
Chocolate Chips: Sprinkle them over the hot bars so they get melty. Milk chocolate gives you that classic s'mores flavor, but semi-sweet or dark chocolate is good too.
Marshmallows: Pile them over the chocolate chips and broil until golden and gooey. Mini marshmallows work best because they cover the top evenly and toast quickly.

How To Make S'mores Pumpkin Bars

This pumpkin bar recipe is easy and comes together in no time. Just follow the simple steps, and you will be digging into a delicious fall dessert in no time.

Two s'mores pumpkin bars stacked on a white plate.

Make the batter. Beat the softened butter and brown sugar in a large bowl until creamy. Add the pumpkin, eggs, and vanilla and mix until smooth.
Add the dry ingredients. Stir together the flour, baking powder, salt, and spices. Add them to the wet ingredients and stir just until combined. Spread the batter evenly in a prepared baking dish.
Bake. Place the pan in a preheated oven and bake until set.
Add the s'mores topping. Sprinkle the chocolate chips over the hot bars immediately, then cover with the mini marshmallows.
Broil. Place the dish under a broiler for about 2 minutes. Watch very closely until the marshmallows are golden brown. Don't walk away! They can go from perfectly toasted to burnt very quickly. Cool completely before cutting.

Recipe Variations

Add graham crackers. For an even bigger s'mores flavor, add graham crackers to the bottom of the pan before you add the batter, just like I did in this chocolate s'mores pudding cake.
Try marshmallow fluff. Instead of marshmallows, spread marshmallow fluff over the chocolate. This gives you an extra-gooey topping.
Finish with Hershey's chocolate. Press a few small pieces of Hershey bars into the toasted marshmallow for a fancy finish, just like this gooey s'mores pie.

BruCrew Tips

Add the toppings right away. As soon as the bars come out of the oven, sprinkle on the chocolate chips and marshmallows. The heat from the bars helps the chocolate start melting underneath the gooey marshmallows.
Watch the marshmallows closely. Seriously, do not walk away! They can go from golden to burnt in seconds. Pull the pan out as soon as they're toasted to your liking.
Let the bars cool completely. I know it's hard to wait, but cutting them while they are warm can get messy.
Use a wet knife. Run a sharp knife under water and rewet it between cuts. The water helps the knife glide through the sticky marshmallow topping better.

Storing and Freezing

Store the bars in a sealed container at room temperature for 3-4 days. You can also keep them in an airtight container in the refrigerator for up to a week. Let them come to room temperature before serving for the best texture.

Wrap individual bars in parchment paper and plastic wrap, then place them in a freezer-safe bag for up to 3 months. Thaw to room temperature before serving. The marshmallows may change texture slightly after freezing.
