Step‑by‑Step Instructions for Pumpkin S’mores Bars
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While it warms up, prepare a 9×9-inch baking dish by lightly spraying it with cooking spray. This ensures easy removal of the delicious Pumpkin S’mores Bars once they’re baked and cool.
Step 2: Mix Base Ingredients
In a large mixing bowl, combine the pumpkin puree, light brown sugar, granulated sugar, melted unsalted butter, and the egg. Whisk the ingredients together until the mixture is smooth and creamy. Then, gently mix in the ground cinnamon, kosher salt, baking powder, and all-purpose flour until just combined, ensuring a rich base for your bars.
Step 3: Layer Base in Dish
Once your batter is ready, pour half of it into the prepared baking dish. Use a spatula to spread the batter evenly across the bottom. Make sure it reaches the corners and is leveled, creating a solid foundation for your Pumpkin S’mores Bars that will bake beautifully.
Step 4: Add Fillings
Sprinkle the chopped Hershey Bars, graham cracker pieces, and mini marshmallows generously over the base layer. Then dollop the Marshmallow Fluff over the toppings, ensuring a gooey texture that will melt deliciously during baking. This layering of sweet goodness is essential for that classic s’mores experience!
Step 5: Cover with Remaining Batter
Carefully spoon the remaining pumpkin batter over the marshmallow mixture. Spread it gently to cover all the fillings, ensuring they’re hidden beneath a delicious layer that will seal in flavors. This step is key to achieving the perfect gooey Pumpkin S’mores Bars.
Step 6: Freeze Bars
Before baking, place the assembled dish in the freezer for at least 30 minutes. This chilling step helps maintain the integrity of the marshmallows during baking, ensuring that they stay fluffy and gooey. It’s a crucial tip for achieving a delightful texture in your final treat.
Step 7: Bake
After chilling, transfer your dish to the preheated oven. Bake the Pumpkin S’mores Bars for approximately 28-30 minutes. You’ll know they’re ready when the top is golden brown and set, and a toothpick inserted comes out mostly clean. Enjoy the rich aroma wafting through your kitchen as they bake!
Step 8: Cool and Slice
Once baked, remove the dish from the oven and let the bars cool completely in the pan. This cooling period is essential for them to set properly. Once cool, slice the Pumpkin S’mores Bars into squares and serve, either warm or at room temperature, to share the comfort of fall flavors with family and friends.

Expert Tips for Pumpkin S’mores Bars

Pumpkin S’mores Bars Recipe FAQs
How do I choose the right pumpkin puree?
Absolutely! When selecting pumpkin puree, look for brands that contain 100% pumpkin without added sugars or spices. If fresh is more your style, you can roast sugar pumpkins, scoop out the flesh, and blend until smooth. Just ensure the puree isn’t watery; too much moisture can affect the texture of your bars.
What’s the best way to store Pumpkin S’mores Bars?
You can store your Pumpkin S’mores Bars at room temperature in an airtight container for up to 3 days. If you want them to last longer, refrigerate them for up to 5 days, but note that they may become firmer. If you’d like to freeze them, wrap individual portions tightly in plastic wrap, then place in an airtight container for up to 1 month. Thaw in the fridge before serving for optimal texture.
Can I freeze Pumpkin S’mores Bars?
Yes! To freeze, first cut the bars into squares. Wrap each piece tightly in plastic wrap, followed by aluminum foil to prevent freezer burn. Store them in a freezer-safe container. They can be frozen for up to 1 month. When you’re ready to enjoy, simply let them thaw in the refrigerator overnight or at room temperature for several hours.
What if my bars are too gooey after baking?
No worries! If your Pumpkin S’mores Bars are too gooey after baking, it could be due to excess moisture in the pumpkin puree or not allowing them to cool completely. You can try placing them back in the oven for an additional 5-10 minutes at the same temperature to firm them up. Additionally, pressing the puree beforehand to remove excess liquid can help in future batches.
Are there any allergy considerations with this recipe?
Absolutely! If you’re making these bars for someone with dietary restrictions, I recommend using a flax egg instead of a regular egg for a vegan option. For those with gluten sensitivities, a gluten-free flour blend works just as well in this recipe. Also, be mindful when choosing chocolate and marshmallows, as some brands may contain allergens like nuts or dairy.
Can pets eat Pumpkin S’mores Bars?
Not at all! While pumpkin itself is safe for dogs, the sugar, chocolate, and marshmallows in these bars are not safe for pets. It’s best to keep these delightful treats away from your furry friends. If you want to share pumpkin with your pet, consider making a simple pumpkin puree treat without sugar or additives just for them!
