Every time I bake a batch, the smell of toasted marshmallows and chocolate instantly takes me back to summer campfires, even if it’s the middle of winter.

Why You’ll Love This S’mores Cookie Bars (Recipe + Video)

• They’re incredibly easy to make – no campfire needed!
• You get that perfect gooey s’mores experience, but in a neat, portable bar.
• The graham cracker cookie base is soft and chewy, a dream come true.
• They’re a guaranteed crowd-pleaser for any gathering or just a cozy night in.

Ingredients You’ll Need

• Unsalted butter: Make sure it’s softened to room temperature. This helps it cream beautifully with the sugar, giving your bars a tender texture.
• Brown sugar: Either light or dark packed brown sugar works wonders here. It adds a lovely caramel note and keeps the bars moist.
• All-purpose flour: Always spoon and level your flour, don’t scoop directly from the bag. This prevents adding too much and making your bars dry.
• Graham cracker crumbs: These are essential for that classic s’mores flavor! You can buy them pre-crushed or crush about 8 full-sheet graham crackers yourself.
• Marshmallow creme: This is the secret to gooey, melty marshmallow goodness without the mess. Store-bought “Fluff” is perfect and easy to find.

How to Make S’mores Cookie Bars (Recipe + Video) Step by Step

First things first, let’s get our oven ready! You’ll want to preheat it to 350°F (177°C). While that’s warming up, grab your 8-inch or 9-inch square baking pan and line it with parchment paper. Make sure to leave some overhang on the sides – trust me, those little “handles” will make lifting the cooled bars out a breeze later.

Next, in a large bowl, we’re going to cream together the softened butter and brown sugar. Use a handheld or stand mixer on medium-high speed for about 3 minutes until it’s light and fluffy. Don’t rush this step, it’s key for a tender bar! Then, add your egg and vanilla extract, beating until they’re just combined. Don’t worry if the mixture looks a little curdled at this point; it’s totally normal and will come together.

In a separate medium bowl, whisk together your dry ingredients: the flour, graham cracker crumbs, baking powder, and salt. Once combined, slowly add this flour mixture to your wet ingredients, beating on medium speed until everything is just mixed. Now for the fun part! Press about two-thirds of this delicious cookie dough into your prepared pan. It will be a thin layer and a bit sticky, so don’t be afraid to use your hands to get it evenly spread. Then, spread that wonderful marshmallow creme on top – it’s sticky, but do your best to get an even layer. Sprinkle with chocolate chips, and then carefully mold the remaining cookie dough into flat pieces and layer them on top. It won’t cover everything, and that’s perfectly okay; some peeking chocolate and marshmallow just adds to the charm!

My Top Tips for Success

• I always make sure my butter and egg are at room temperature. It really helps everything combine smoothly.
• In my experience, lining the pan with parchment paper is a non-negotiable for easy removal and clean-up.
• Trust me on this one: don’t overbake! You want the top to be just lightly golden brown for that perfect gooey center.
• Cooling completely is crucial before cutting. Warm bars will be a gooey mess, but patient cooling leads to perfect squares.
• If your marshmallow creme is too stiff to spread easily, you can very lightly warm it in the microwave for a few seconds to make it more pliable.

Common Mistakes to Avoid

• Overmixing the dough: This can lead to tough bars. Mix until just combined after adding the flour.
• Overbaking: If you bake them too long, the bars will lose their gooey center and become dry. Keep an eye on that lightly golden top.
• Not cooling completely before cutting: Cutting warm bars will result in a sticky, crumbly mess. Patience is a virtue here!
• Not using room temperature ingredients: Cold butter and eggs won’t cream together properly, affecting the texture of your cookie base.
• Skimping on the parchment paper overhang: Without enough overhang, lifting the bars out can be a real struggle.

Frequently Asked Questions

Can I use different types of chocolate?

Absolutely! While semi-sweet chocolate chips are traditional, milk chocolate or even chopped dark chocolate would be delicious. Feel free to experiment!

Can I make these in a different size pan?

You can, but you’ll need to adjust the baking time. A larger pan might mean a shorter bake, and a smaller pan (like a 9×13) might make thinner bars, so keep an eye on them.

What if I don’t have graham cracker crumbs?

You can easily make your own! Just crush about 8 full-sheet graham crackers in a food processor or by hand until fine crumbs form.

Can I freeze these S’mores Cookie Bars?

Yes, you can! Once completely cooled, wrap individual bars tightly in plastic wrap and then place them in an airtight freezer-safe container for up to 2-3 months. Thaw at room temperature.

My marshmallow creme is really sticky, any tips for spreading it?

Try lightly greasing your offset spatula or the back of a spoon with a tiny bit of non-stick spray or butter before spreading the marshmallow creme. It helps a lot!
