½ cup (113 g) unsalted butter, melted and cooled
½ cup (110 g) packed light brown sugar
⅓ cup (65 g) granulated sugar
1 teaspoon (5 ml) alcohol-free vanilla extract
1 large egg yolk
1½ teaspoons (7 ml) honey
⅓ cup plus 1 tablespoon (90 ml) pure pumpkin puree, blotted dry
1 teaspoon pumpkin pie spice
¼ teaspoon baking powder
¼ teaspoon baking soda
½ teaspoon kosher salt
1⅓ cups (190 g) all-purpose flour
½ cup (85 g) halal-suitable dark chocolate chips
15 large halal-certified marshmallows, cut in half
¾ cup (113 g) halal-suitable dark chocolate chips or chunks
½ cup (35 g) roughly crushed halal-suitable graham crackers, approximately 5 squares
2 additional graham cracker squares, roughly crushed, for topping

Instructions

Step 1: Preheat the oven

Preheat your oven to 350°F (175°C).

Line an 8×8-inch square baking pan with parchment paper, allowing approximately 1 inch of parchment to extend over the edges.

The overhanging parchment will make it easier to lift the baked bars out of the pan once they have cooled.

Set the prepared pan aside.

Step 2: Prepare the pumpkin puree

Place the pumpkin puree on a plate lined with several layers of paper towels.

Gently press additional paper towels over the pumpkin to absorb excess moisture.

Continue blotting until the pumpkin looks noticeably thicker and less watery.

Measure the required amount before blotting so the recipe maintains the intended balance of ingredients.

Step 3: Combine the butter and sugars

In a large mixing bowl, combine the melted and cooled butter, packed light brown sugar, granulated sugar, and alcohol-free vanilla extract.

Whisk until the mixture is smooth and evenly blended.

The brown sugar will help create a rich flavor and soft, chewy texture.

Step 4: Add the wet ingredients

Add the egg yolk, honey, and blotted pumpkin puree to the butter mixture.

Whisk until the ingredients are fully incorporated and the mixture becomes smooth.

Scrape down the sides of the bowl as needed to make sure everything is evenly combined.

Step 5: Add the spices and leavening ingredients

Sprinkle the pumpkin pie spice, baking powder, baking soda, and kosher salt over the wet mixture.

Whisk gently until evenly distributed.

The pumpkin pie spice adds a warm combination of cinnamon and other aromatic spices that complement the chocolate and marshmallows.

Step 6: Incorporate the flour

Add the all-purpose flour to the bowl.

Using a spatula, gently fold the flour into the wet ingredients until no dry streaks remain.

Avoid overmixing, as this can make the finished cookie bars tough rather than tender and chewy.

The dough should be thick and soft.

Step 7: Fold in the chocolate and graham crackers

Add the ½ cup of dark chocolate chips and the ½ cup of roughly crushed graham crackers.

Fold gently until they are evenly distributed throughout the pumpkin cookie dough.

Reserve the additional chocolate chunks and graham crackers for layering.

Step 8: Press the dough into the pan

Transfer approximately three-quarters of the pumpkin cookie dough into the prepared baking pan.

Using your fingers or the back of a spoon, press the dough into an even layer across the bottom.

Reserve the remaining quarter of the dough for the topping.

Step 9: Add the marshmallows

Arrange the halved halal-certified marshmallows over the cookie dough, placing them cut-side down.

Position the marshmallows close together so they cover most of the surface.

Gently press them into the dough to help them stay in place.

Step 10: Add the chocolate and graham crackers

Scatter the remaining ¾ cup of dark chocolate chips or chunks over the marshmallows.

Sprinkle the two additional crushed graham cracker squares evenly over the chocolate.

These layers give the pumpkin chocolate marshmallow bars their classic s’mores flavor and texture.

Step 11: Add the remaining cookie dough

Break the reserved pumpkin cookie dough into small pieces.

Scatter the pieces over the marshmallow and chocolate layers, gently pressing them into place.

Leave some open spaces so the marshmallows can peek through as the bars bake.

This creates a beautiful rustic topping with golden cookie dough, melted chocolate, and toasted marshmallow.

Step 12: Bake the bars

Place the pan in the preheated oven.

Bake for 24–28 minutes, or until the cookie dough is golden brown around the edges and the center looks set.

The marshmallows should be puffed and lightly toasted, while the chocolate becomes soft and melted.

Your Pumpkin S’mores Bars are ready when the cookie portions are baked through and the edges have developed a beautiful golden color.

Step 13: Cool before slicing

Remove the baking pan from the oven and place it on a wire rack.

Allow the bars to cool completely in the pan.

This cooling time is important because the melted chocolate and marshmallow filling need time to settle.

Once cooled, use the parchment paper overhang to lift the bars out of the pan.

Step 14: Slice and serve

Place the cooled bars on a cutting board.

Using a sharp knife, cut into 12 squares or 16 smaller portions.

For cleaner slices, wipe the knife between cuts.

Serve at room temperature or warm individual bars slightly before enjoying.

Tips & Tricks

Blot the pumpkin puree thoroughly

Pumpkin naturally contains a significant amount of moisture. Removing some of that moisture helps prevent the cookie dough from becoming overly soft or cakey.

Use paper towels to gently absorb excess liquid before adding the pumpkin to the batter.

Use pure pumpkin puree

Choose plain pumpkin puree rather than pumpkin pie filling.

Pumpkin pie filling contains added sugar and spices that can change the flavor and texture of the recipe.

Allow the melted butter to cool

The butter should be melted but not hot when combined with the sugars and egg yolk.

Hot butter can affect the texture of the dough and may begin cooking the egg.

Don’t overmix the flour

Mix only until the flour disappears into the dough.

Overmixing can develop too much gluten and make the bars firmer than intended.

Choose good-quality dark chocolate

Dark chocolate balances the sweetness of the marshmallows and brown sugar.

You can use semisweet chocolate if you prefer a slightly sweeter dessert.

Use halal-certified marshmallows

Many conventional marshmallows contain animal-derived gelatin.

Choose marshmallows made with halal-certified gelatin or another suitable halal-friendly formulation.

Cut the marshmallows in half

Halving the marshmallows helps distribute them evenly and creates more consistent pockets of gooey filling.

Kitchen scissors make this step especially easy.

Leave some marshmallows exposed

When adding the final layer of cookie dough, avoid covering every marshmallow.

The exposed marshmallows will puff and toast during baking, creating the beautiful s’mores appearance.

Avoid overbaking

The bars will continue to firm up as they cool.

Remove them when the cookie dough is golden and set rather than waiting until the center becomes completely firm.

Let the bars cool before cutting

Freshly baked marshmallow and chocolate are extremely soft and sticky.

Cooling helps the layers settle and makes slicing much easier.

FAQ

1. Why do I need to blot the pumpkin puree before baking?

Pumpkin puree contains a significant amount of water, which can affect the texture of baked goods.

Removing excess moisture helps create chewy pumpkin bars rather than a soft, cake-like dessert.

To blot the pumpkin, spread the measured puree over several layers of paper towels and gently press with additional towels.

The pumpkin should become thicker and less watery before being added to the dough.

2. Can I make pumpkin s’mores bars ahead of time?

Yes! These bars are a great make-ahead dessert.

Bake them according to the recipe and allow them to cool completely.

Store them in an airtight container at room temperature for up to 2 days, or refrigerate them for longer storage.

The chocolate and marshmallow layers will become firmer when chilled, but you can warm individual bars slightly before serving.

3. Can I use milk chocolate instead of dark chocolate?

Absolutely.

Milk chocolate creates a sweeter, creamier filling, while dark chocolate provides a richer flavor that balances the sweetness of the marshmallows.

Semisweet chocolate is another excellent option.

You can also combine different types of chocolate for a more complex flavor.

4. How do I keep pumpkin cookie bars chewy instead of cakey?

The most important step is removing excess moisture from the pumpkin puree.

Using the correct amount of flour, avoiding overmixing, and not overbaking also help maintain a chewy texture.

Allow the bars to cool completely before slicing, as they continue to firm up after leaving the oven.

5. Can I make these pumpkin graham cracker bars without pumpkin pie spice?

Yes.

The pumpkin pie spice adds warmth and seasonal flavor, but the bars will still be delicious without it.

You can replace it with ground cinnamon or a combination of cinnamon, ginger, nutmeg, and cloves.

For a milder flavor, simply reduce the amount of spice.

6. How do I know when the marshmallow chocolate bars are fully baked?

Look for golden brown cookie dough around the edges and a center that appears set rather than wet.

The marshmallows should be puffed and lightly toasted, and the chocolate should be melted.

Avoid relying on a toothpick test because the melted chocolate and marshmallows can make the toothpick appear wet even when the cookie dough is baked.

Storage

Room Temperature

Allow the bars to cool completely before storing.

Place them in an airtight container, separating layers with parchment paper to prevent sticking.

Store in a cool, dry place for up to 2 days.

Refrigerator

For longer storage, transfer the cooled bars to an airtight container.

Refrigerate for up to 5 days.

The chocolate and marshmallow filling will become firmer when chilled, so allow the bars to sit at room temperature briefly before serving if you prefer a softer texture.

Freezer

Wrap individual bars tightly in plastic wrap or parchment paper.

Place them in a freezer-safe container or bag.

Freeze for up to 2 months for the best quality.

The marshmallow texture may change slightly after freezing and thawing.

Thawing

Transfer frozen bars to the refrigerator and allow them to thaw overnight.

Alternatively, thaw individual bars at room temperature for a short period before serving.

Reheating

For a warm, gooey texture, place an individual bar on a microwave-safe plate.

Heat for approximately 10–15 seconds, checking frequently.

The marshmallow and chocolate filling can become very hot, so allow the bar to cool slightly before eating.
