What Ingredients You Will Need

This recipe uses simple ingredients you probably already have in your pantry. Here’s what you’ll need:

• All-purpose flour: The base of the cookie dough. You can use a 1:1 gluten-free blend if needed.
• Graham cracker crumbs: Adds that signature s’mores flavor.
• Baking powder: Helps give the dough a slight lift.
• Salt: Balances the sweetness.
• Unsalted butter, softened: The key to a rich, buttery dough.
• Brown sugar: Adds moisture and a subtle caramel flavor.
• Granulated sugar: For a touch of sweetness and structure.
• Large eggs: Bind everything together.
• Vanilla extract: Enhances all the flavors.
• Chocolate chips: Semi-sweet or milk chocolate works great. Use a mix for extra indulgence!
• Mini marshmallows: The gooey layer that makes these bars irresistible.
• Additional graham crackers: Broken into pieces for that classic s’mores texture.

You can always get creative with substitutions, like swapping graham crackers for digestive biscuits or using dark chocolate for a less sweet option. The possibilities are endless!

Equipment Needed

You don’t need fancy gadgets for this recipe. Here’s what you’ll want to have on hand:

• 9×13-inch baking pan: The perfect size for thick, chewy bars.
• Parchment paper: Makes lifting the bars out of the pan a breeze.
• Mixing bowls: One for the dry ingredients, one for the wet.
• Electric mixer: A hand or stand mixer to cream the butter and sugars together.
• Spatula: For folding in the chocolate chips and spreading the dough evenly.

If you don’t have parchment paper, you can grease the pan well, but trust me, parchment makes cleanup so much easier!

Preparation Method

1. Preheat your oven: Set it to 350°F (175°C). Line your baking pan with parchment paper, leaving some overhang for easy removal.
2. Mix the dry ingredients: In a medium bowl, combine 2 cups (250g) of flour, 1 cup (120g) of graham cracker crumbs, 1 tsp baking powder, and 1/2 tsp salt. Set aside.
3. Cream the butter and sugars: In a large mixing bowl, beat 3/4 cup (170g) of softened unsalted butter, 1 cup (200g) of brown sugar, and 1/2 cup (100g) of granulated sugar until light and fluffy.
4. Add the wet ingredients: Beat in 2 large eggs, one at a time, followed by 1 tsp of vanilla extract.
5. Combine the mixtures: Gradually add the dry ingredients to the wet, mixing just until combined.
6. Add the chocolate chips: Fold in 1 1/2 cups (270g) of chocolate chips. Reserve a handful for sprinkling on top.
7. Assemble the layers: Press half of the dough into the prepared pan. Sprinkle with 2 cups (100g) of mini marshmallows and broken graham cracker pieces.
8. Top with remaining dough: Spread the rest of the dough over the marshmallows. Don’t worry if some marshmallows peek through—it’s part of the charm!
9. Bake: Bake for 25-30 minutes, or until the edges are golden brown and the center is set.
10. Cool and cut: Let the bars cool completely in the pan before lifting them out and slicing into squares.

Pro tip: For clean cuts, use a sharp knife and wipe it down between slices.

Cooking Tips & Techniques

• Use room temperature butter and eggs for a smoother dough.
• Don’t overmix the dough once you add the dry ingredients—this keeps the bars tender.
• Let the bars cool completely before slicing; this prevents them from falling apart.
• Sprinkle extra chocolate chips on top right after baking for a pretty finish.
• If you like your marshmallows extra toasty, pop the pan under the broiler for 1-2 minutes. Watch closely!

Variations & Adaptations

• Peanut Butter Twist: Swirl in a few dollops of peanut butter before baking.
• Nut-Free Option: Use allergy-friendly chocolate chips and check your graham crackers for cross-contamination.
• Dark Chocolate Lovers: Replace semi-sweet chocolate with dark chocolate for a richer taste.
• Seasonal Flair: Add a sprinkle of cinnamon or pumpkin spice to the dough for a fall-inspired treat.
• Gluten-Free: Use gluten-free flour and graham crackers.

I’ve even tried adding caramel drizzle once, and it was a game-changer!

Serving & Storage Suggestions

These bars are best served slightly warm or at room temperature. Pair them with a tall glass of milk, or better yet, a scoop of vanilla ice cream for an extra indulgent treat.

Store leftovers in an airtight container at room temperature for up to 3 days. For longer storage, freeze the bars in a single layer, then transfer to a freezer-safe bag. They can be frozen for up to 2 months. Just thaw at room temperature when ready to enjoy!

FAQs

Can I make these S’mores Cookie Bars ahead of time?

Yes! These bars keep well for up to 3 days at room temperature, making them a great make-ahead dessert.

Can I use large marshmallows instead of mini ones?

Mini marshmallows work best because they melt evenly, but you can chop large marshmallows into smaller pieces as a substitute.

How do I prevent the marshmallows from sticking to the knife?

Use a sharp knife and grease the blade lightly with non-stick spray before slicing.

Can I double the recipe?

Absolutely! Use two 9×13-inch pans, or bake in a larger sheet pan. Keep an eye on the baking time.

What’s the best way to reheat these bars?

Pop a bar in the microwave for 10-15 seconds to make it warm and gooey again!
