Ingredients

individual ingredients for pumpkin spice smore bars laid out against a white background.
  • Butter: I always use organic salted butter. But unsalted butter is fine if you prefer, just add 1/4 teaspoon of salt.
  • Brown Sugar: I use my Homemade Dark Brown Sugar, store bought also works. Using dark brown sugar gives a more rich depth of flavor to these s'more bars. Light brown sugar will work, but you just won't have as dark of a color or rich of a flavor.
  • Vanilla Extract: Use a high quality vanilla extract, not imitation.
  • Pumpkin Spice: I use my Homemade Pumpkin Pie Spice Mix, which is just a mix of cinnamon, ginger, cloves, and nutmeg. But you can use a store-bought pumpkin spice mix too.
  • Heavy Whipping Cream: This is used as an egg replacer. I love using this for s'more bars because you can make them super gooey without the worry of under baking a dough with eggs!
  • All Purpose Flour: My favorite is Cairnspring Mills.
  • Baking Soda: Use baking soda, not salt. Be sure to check out my post the Difference Between Baking Soda and Baking Powder for more info on leavening agents.
  • Marshmallow Creme: I use Toonie Moonie Marshmallow Crème, which is basically a fluffy marshmallow version of fluff.

Baker's Tips

  • Always weigh ingredients for the best results.
  • Make sure you are using soft butter. I like to soften butter naturally on the countertop. But, if you must microwave it, be sure to only do 10 second intervals per ½ cup. As the weather gets cooler, I like to leave butter out overnight too!
  • Vegan: Replace the butter with vegan butter. I recommend Miyoko's, this is what I used for testing.
  • I like to use gloves when forming the cookie dough into the pan. Maybe it’s my commercial bakery past, but kitchen gloves are so helpful for things like this! The dough should not be too sticky that you can’t handle it, but if you don’t want to use your hands, you can also grease a spatula and use that to press it down.
  • I use dark chocolate chips, but feel free to use milk chocolate if you want more of a traditional s’more flavor. You can also use semi-sweet chocolate chips or even white chocolate. They would all be delicious!
  • If you want these a bit crispier as opposed to soft and gooey, then bake them for about 5 minutes longer.
  • Be sure to store these in an airtight container so they stay fresh. They are best when eaten within the first couple days of being baked but will be good for up to 5 days.

Recipe FAQ's

Can I use another kind of chocolate?

Yes, if you want to use milk chocolate or even dark chocolate bars, those would work too. If you're using chocolate bars, just be sure to chop them into small pieces before adding to the pan.

Can I make these vegan or dairy-free?

Yes, just use your favorite vegan butter in place of butter. I recommend Miyoko's, this is what I use for testing.

Does pumpkin make cookie bars more cakey?

Pumpkin has a lot of moisture, so it can make cookie bars more cakey. But, we're using it as an egg replacer and I feel like it doesn't do this as much when there are no eggs! I always use Farmer's Market Organic Pumpkin Puree and I never strain or blot the moisture out. But, if you are using a different brand and you notice it's very wet, you may want to blot out some of the moisture with paper towels.

Can you taste the pumpkin in these bars?

Yes, there's pumpkin and pumpkin spice, making these a perfect fall treat!

Why are my pumpkin s’more bars so soft or gooey?

S'mores bars are incredibly soft and gooey. If you want them more well done, you can bake a few extra minutes.

Does marshmallow fluff stay gooey after baking?

I'm using Organic Toonie Moonie Marshmallow Creme, which stays good after baking. I don't know about fluff as I don't use that.

Should pumpkin bars still be soft when done baking?

They will look a little jiggly when coming out of the oven. Let them cool completely before removing or cutting so they don't break.

How do I know when pumpkin s’more bars are done baking?

Look for golden brown edges, they will still be a little jiggly in the center when they come out of the oven.

What texture should pumpkin s’more bars have?

They are soft, chewy and gooey!

Why are my bars dry instead of gooey?

This can happen if you over bake them. And also if you use too much flour probably from incorrect measuring. Be sure to use a digital food scale for the best results.

Why are my bars falling apart when sliced?

If you don't let them cool completely before slicing, they can break.

How do you store s'more bars?

Store in an airtight container at room temperature for up to 5 days.
