S’Mores Bars

These bars start with a graham cracker cookie dough base that’s soft and chewy but still sturdy enough to hold all the gooey layers. You press half the dough into the pan, then layer it with milk chocolate and marshmallow fluff (or mini marshmallows), then top it all off with the rest of the dough and bake until golden and bubbling.

They slice up perfectly, are easy to pack or serve at parties, and they taste like summer wrapped in a bar cookie.

Ingredients

For the Graham Cracker Cookie Dough:

• 1½ cups graham cracker crumbs (about 10 full sheets)
• 1 cup all-purpose flour
• ½ teaspoon baking powder
• ½ teaspoon salt
• ½ cup (1 stick) unsalted butter, softened
• ⅓ cup granulated sugar
• ⅓ cup brown sugar
• 1 large egg
• 1 teaspoon vanilla extract

For the Filling:

• 2 full-sized milk chocolate bars (like Hershey’s), or 1 cup chocolate chips
• 1 cup marshmallow fluff (or 1½ cups mini marshmallows)

Optional Add-Ins

• Peanut butter or Nutella swirled into the filling
• Use dark chocolate for a richer flavor
• Add a sprinkle of sea salt on top before baking

Step-by-Step Instructions

Step 1: Prep

• Preheat oven to 350°F (175°C).
• Line an 8×8-inch baking pan with parchment paper, leaving a little overhang on the sides for easy lifting.

Step 2: Make the Dough

1. In a medium bowl, whisk together graham cracker crumbs, flour, baking powder, and salt.
2. In a large bowl, beat butter and both sugars together until light and fluffy (about 2 minutes).
3. Add the egg and vanilla, and mix until combined.
4. Gradually mix in the dry ingredients until a soft dough forms.

Step 3: Layer It Up

1. Press a little more than half the dough into the bottom of the prepared pan to form the crust.
2. Lay the chocolate bars on top in an even layer, breaking them to fit if needed (or sprinkle chocolate chips evenly).
3. Gently spread the marshmallow fluff over the chocolate. (If using mini marshmallows, scatter them evenly across the chocolate.)
4. Crumble the remaining dough over the top and lightly press down—don’t worry about covering everything completely. A little marshmallow peeking through is perfect.

Step 4: Bake

• Bake for 20–25 minutes, or until the top is golden brown and the edges are set.
• Let cool completely before slicing—seriously, this helps them set up and hold their shape.

Tip: For extra clean cuts, chill the bars in the fridge for 30 minutes before slicing.

How to Serve

• Classic: Slice into squares and serve at room temp.
• Warm it up: Pop a square in the microwave for 10 seconds for extra gooey vibes.
• With ice cream: Top a warm bar with vanilla or chocolate ice cream and a drizzle of chocolate syrup.
• On a dessert platter: Pair with brownies and cookies for a sweet sampler.

Additional Tips

1. Use parchment: It makes lifting and slicing these bars so much easier.
2. Marshmallow fluff vs. minis: Fluff gives a smooth, gooey layer while mini marshmallows toast and puff up a bit—both work, it’s just personal preference.
3. Chill to slice clean: These bars cut best when fully cooled or even chilled.
4. Double it: Use a 9×13-inch pan and double the recipe for a crowd.
5. Want toasted tops? Throw them under the broiler for 1–2 minutes to get that fire-roasted marshmallow look.

Recipe Variations

• Peanut Butter S’mores Bars: Add a layer of peanut butter between the chocolate and marshmallow.
• S’mores Blondies: Mix chopped graham crackers, chocolate chips, and marshmallows into a blondie batter instead.
• S’mores Cookie Bars: Use your favorite chocolate chip cookie dough as the base and top.
• Gluten-Free: Use gluten-free graham crackers and flour for a GF-friendly version.
• Vegan: Use plant-based butter, egg substitute, dairy-free chocolate, and vegan marshmallows or fluff.

Storage & Freezing

• Room Temp: Store in an airtight container for up to 3 days.
• Fridge: Keep chilled for up to 5 days if you prefer a firmer bar.
• Freezer: Freeze for up to 2 months. Wrap tightly and thaw at room temp before serving.

FAQ

Can I use regular cookie dough instead of graham cracker dough?
You can, but the graham cracker flavor is what gives these bars that classic s’mores vibe.

Do I have to use marshmallow fluff?
Nope! Mini marshmallows work just as well—they just give you more of that toasted effect.

Can I make these ahead of time?
Yes! They taste just as good (if not better) the next day once the layers have had time to set.

Can I use chocolate chips instead of bars?
Absolutely. Just sprinkle about 1 cup evenly across the bottom layer.
