So let’s get into it now and make S’mores Cookie Bars that feel just as magical as the classic treat we all grew up loving.

Ingredients

Here’s what I use for this recipe. You can always make substitutions if you prefer!

• Graham cracker crumbs – They create the base and add that signature honey-toasted flavor.
• All-purpose flour – Helps bulk up the dough and adds structure.
• Brown sugar – Adds sweetness and extra moisture for a soft chewy texture.
• Granulated sugar – Lifts the sweetness and helps the top layer brown beautifully.
• Butter – Binds the graham mixture and creates a rich tender crust.
• Egg – Gives the dough structure and helps everything set as it bakes.
• Vanilla extract – Enhances the flavor and brings a warm aroma.
• Chocolate bars – These melt into perfect creamy pockets of chocolatey goodness.
• Marshmallows – Toast and puff in the oven to create the classic s’mores gooey layer.
• Baking powder – Helps lighten the cookie dough mixture.
• Salt – Balances sweetness and enhances every flavor in the bar.

Tools You’ll Need

• Mixing bowls – I use them to separate wet and dry ingredients so the dough mixes evenly.
• Whisk – Perfect for blending dry ingredients and preventing lumps.
• Rubber spatula – Helps fold and spread the dough without overmixing.
• 9×9 baking pan – Shapes the bars into thick even layers.
• Parchment paper – Makes lifting the finished bars out clean and easy.
• Measuring cups and spoons – Ensure accuracy in every layer.
• Hand mixer or stand mixer – Makes creaming the butter and sugars quick and smooth.

Instructions

Step 1: Prepare the Pan

I start by lining a 9×9 baking pan with parchment paper so I can lift the bars out easily after baking.

Step 2: Combine the Dry Ingredients

I whisk together the graham cracker crumbs, flour, baking powder, and salt until everything looks evenly combined.

Step 3: Cream the Butter and Sugars

In another bowl I beat the butter, brown sugar, and granulated sugar until they’re light and fluffy because this creates that soft cookie-like texture.

Step 4: Add Egg and Vanilla

I mix in the egg and vanilla extract until everything looks smooth and well blended.

Step 5: Bring the Dough Together

I slowly add the dry mixture into the wet mixture and stir until the dough forms without overmixing.

Step 6: Press the Bottom Layer

I press about two-thirds of the dough into the bottom of the lined pan making sure the layer is even and reaches every corner.

Step 7: Add the Marshmallow and Chocolate

I spread marshmallows over the dough then lay the chocolate pieces across the top making sure every bite gets both.

Step 8: Add the Top Layer

I crumble the remaining dough over the top leaving some marshmallow and chocolate peeking through for that rustic s’mores look.

Step 9: Bake

I bake the bars at 350°F until the edges are golden and the top looks lightly crisp.

Step 10: Cool and Slice

I let the bars cool completely so they slice neatly without melting everywhere.

Tips

I like to refrigerate the dough for ten minutes before layering because it makes it easier to crumble the top evenly. I also love adding a sprinkle of flaky salt on top before baking because it enhances the chocolate and cuts through the sweetness beautifully. And if you prefer extra gooey bars I sometimes add a handful of mini marshmallows under the chocolate layer for an extra melt effect.

Ways to Serve

I enjoy serving these S’mores Cookie Bars slightly warm because the chocolate stays soft and the marshmallows stay gooey. These bars pair beautifully with a scoop of vanilla ice cream which melts into all the layers. They also taste amazing chilled if you prefer a firmer cookie texture and they travel well for picnics parties and potlucks making them a fun treat to share anywhere.

Storage Instructions

I store leftover S’mores Cookie Bars in an airtight container at room temperature for up to three days. If I want them to last longer I refrigerate them and they keep fresh for about a week. They also freeze well and I wrap each bar individually before storing them in a freezer-safe bag for up to two months. When I’m ready to enjoy one I thaw it at room temperature or warm it in the microwave for a few seconds.

Frequently Asked Questions

How do I keep S’mores Cookie Bars from becoming too crumbly?

Can I use chocolate chips instead of chocolate bars in S’mores Cookie Bars?

Yes you can swap the chocolate bars for chips and they melt nicely while adding extra chocolate pockets.

Can I double this S’mores Cookie Bars recipe?

Absolutely doubling works well in a 9×13 pan just keep an eye on the baking time.
