Why You’ll Love This Graham Cracker S’mores Bars Recipe

  • These bars have that irresistible gooey, chewy texture you crave in a s’more, all baked into one delightful bite.
  • It’s so easy to make! You don’t need any fancy equipment, just a mixer and a baking sheet.
  • The flavors are spot on—rich chocolate, sweet marshmallow, and that signature graham cracker crunch.
  • They’re perfect for parties, potlucks, or just a cozy night in. Everyone loves a s’mores bar!

Ingredients You’ll Need

  • Unsalted Butter: Make sure it’s at room temperature! This helps it cream beautifully with the sugars, creating a light and fluffy base for your bars. Don’t use cold butter, or your dough won’t be as smooth.
  • Granulated Sugar and Brown Sugar: The combination gives these bars both sweetness and a lovely chewiness. Brown sugar adds a deeper, molasses-like flavor.
  • Eggs: These bind everything together and add moisture.
  • Vanilla: Always use good quality vanilla extract. It enhances all the other flavors.
  • Flour: Regular all-purpose flour works perfectly here.
  • Salt: Don’t skip the salt! It balances the sweetness and really makes the flavors pop.
  • Baking Soda: This is our leavening agent, helping the bars rise just a bit and keeping them tender.
  • Cinnamon: Just a touch of cinnamon adds a wonderful warmth that complements the graham crackers and chocolate. Trust me, it’s a secret ingredient that makes these bars extra special.
  • Mini Marshmallows: We use these both in the dough and on top for that classic gooey s’mores effect. Mini ones melt perfectly.
  • Semi-Sweet Chocolate Chips: A mix of regular and mini chips ensures chocolate in every single bite!
  • Hershey’s Bars: Breaking these into squares and pressing them on top is key for that iconic s’mores chocolate melt.
  • Honey Graham Crackers: These form the perfect crunchy base and provide that essential s’mores flavor. You’ll need about two sleeves.

How to Make Graham Cracker S’mores Bars Recipe Step by Step

First things first, preheat your oven to 375°F (190°C). You’ll also want to line a standard baking sheet with parchment paper or a baking mat. This makes cleanup so much easier and prevents sticking!

Now for the dough! In a stand mixer, or with a hand mixer in a large bowl, you’re going to cream together your room temperature butter, granulated sugar, and brown sugar. Beat them for about two minutes until the mixture is light and fluffy. This is where you’re building the foundation for a tender bar. Then, add your eggs and vanilla extract and beat until everything is well combined.

In a separate medium bowl, whisk together your dry ingredients: flour, salt, baking soda, and cinnamon. With your mixer on low speed, gradually add these dry ingredients to your wet mixture. Once it’s just combined, gently fold in one cup of mini marshmallows, the chocolate chips, and the mini chocolate chips. Try not to overmix here! This is where the magic happens and your dough comes together.

Next, arrange your graham crackers on the prepared baking sheet. Lay them out so they cover the entire sheet, touching each other. They should be pretty snug! Then, use a standard cookie scoop to place balls of dough onto each cracker. Don’t worry if it looks like a lot of dough; you want it to spread and cover the whole sheet. If you have any gaps, just use the remaining dough to fill them in.

Bake the bars for 6-7 minutes. Then, take them out of the oven. This is the fun part! Immediately press the Hershey’s bar pieces into the top of the partially baked dough. Sprinkle the remaining 1/4 cup of mini marshmallows into any gaps. Pop them back into the oven for another 6-7 minutes, or until the dough is golden brown and the marshmallows are lightly toasted. Once they’re done, let them cool on a wire rack for about 20 minutes. Then, transfer the whole sheet into the refrigerator for another 20 minutes to help them solidify before cutting them into perfect squares!

My Top Tips for Success

  • I always make sure my butter is truly at room temperature. It makes a huge difference in the texture of the dough.
  • Don’t overmix the dough once you add the dry ingredients or the chocolate and marshmallows. Just mix until combined to keep your bars tender.
  • Trust me on this one, arranging the graham crackers snugly is key. It creates a solid base for your bars.
  • When you pull them out halfway, work quickly to add the chocolate and marshmallows. The dough is warm and ready to receive them!
  • Cooling on a wire rack first, then chilling in the fridge, helps them set up perfectly for clean cuts.

Common Mistakes to Avoid

  • Using cold butter: This will result in a lumpy dough that doesn’t cream properly, affecting the final texture of your Graham Cracker S’mores Bars Recipe. Make sure it’s softened!
  • Overmixing the dough: Overmixing can develop the gluten in the flour too much, leading to tough bars instead of tender ones. Mix until just combined.
  • Not lining the pan: The sticky s’mores ingredients will make cleanup a nightmare if you don’t use parchment paper or a baking mat.
  • Skipping the chilling step: These bars are gooey when warm, which is great for eating! But for neat squares, a quick chill in the fridge is essential.

How to Store Graham Cracker S’mores Bars Recipe

  • Countertop: Store in an airtight container at room temperature for up to 2-3 days.
  • Refrigerator: Keep in an airtight container for up to 5 days. They’re great chilled too!
  • Freezer: Wrap individual bars tightly in plastic wrap, then place in a freezer-safe bag or container for up to 1-2 months. Thaw at room temperature.

Frequently Asked Questions

What kind of chocolate works best for s’mores bars?

Semi-sweet chocolate chips are perfect for the dough, and classic Hershey’s milk chocolate bars are ideal for pressing on top to get that authentic s’mores melt.

Can I use different types of marshmallows?

Mini marshmallows work best for melting evenly both in the dough and on top. Larger marshmallows might not melt as nicely into the bars.

Do I have to chill the bars?

While you can eat them warm and gooey, chilling them in the refrigerator for about 20 minutes makes them much easier to cut into clean, neat squares.

Can I double this recipe?

Yes, you can double the recipe! You might need two standard baking sheets or bake them in batches, depending on the size of your oven.

Why did my graham crackers get soggy?

If your graham crackers seem soggy, it might be that the dough was too wet or they were baked for too long. Ensure your butter is at room temperature and don’t overmix the dough.
