Bake a whole pan of s’mores cookie bars in just 35 minutes… I dare you to eat just one!!

titled: Snickerdoodle S'mores Bars


S’mores Bars

Whenever we have friends and family coming over, I get all amped up about planning the menu… and I use it as an opportunity to test out new recipes!

The meal comes together in a snap, especially for a barbecue, but dessert dessert dessert. Does anyone else have this problem?

Nothing says cookout like roasting marshmallows, so s’mores are where I started.

And since I’ve already got recipes for cones, cake, and even hand pies, I knew I needed to come up with something truly unique!

One thought led to another, I circled back to cookies, and then it hit me… snickerdoodles!

Soft, chewy, not too sweet — the perfect complement to rich chocolate and marshmallow…

And that’s how this s mores bars recipe was born!!

Ingredient Notes and Substitutions

  • All-Purpose Flour – Stick with the classic! Everyone’s got it in their pantries, and you have control over the leavening ingredients too.
  • Unsalted Butter – This needs to be softened before you cream it with the sugar. Let it sit at room temp or microwave for 10 seconds at 50% power.

    You can use salted butter for greasing the pan and making the marshmallow drizzle, but unsalted is a must for the dough.
  • Brown Sugar – I love the hint of caramel flavor this adds to snickerdoodle s’mores bars, plus it makes the dough extra tender and moist too!
  • Cinnamon & Nutmeg – Yes, nutmeg!

    Feel free to leave it out if you’re not a fan, but it helps balance out the sweetness from the snickerdoodle, chocolate, and marshmallow flavors.
  • Eggs – You’ll get a smoother s’more bars dough if these are at room temperature first. Simply let them sit on the counter for 30-45 minutes before getting started.
  • Chocolate & Marshmallows – Use classic Hershey’s bars or your favorite alternative, so long as it melts easily.

    I love mini marshmallows for this s mores bars recipe, but you could easily swap in marshmallow creme for something extra gooey!

    It also doubles as the drizzle on top when softened in the microwave.

  • Use butter to grease your baking pan.

Instead of the usual nonstick spray, run a stick of butter all along the bottom and sides — and don’t forget the corners!

But that’s not all! Then, you’ll dust the buttered pan with granulated sugar so every inch of your s’mores cookie bars has that signature sugary coating.

  • Press the dough gently into the pan.

You don’t want to press down too hard and compact it, or the cookie layers will be tough.

Sometimes, it’s easier to place the dough in the pan and add a layer of plastic wrap on top.

You can smooth out the dough without it sticking to your fingers, then remove the plastic before continuing.

And if you’re fine with a more rustic look, you can drop in small pieces of dough at the end instead of creating a smooth top layer.

Just be sure there aren’t any huge gaps between each piece.

  • Cool completely before slicing.

Desserts that are baked in deep pans, like these s’more bars, cool faster on a wire rack than sitting flat on the stove or counter.

That doesn’t mean remove them from the pan! Just place the whole pan on top of the rack so cooler air can reach the bottom too.

Prep Ahead

  • Grease baking pan
  • Bring butter and eggs to room temp
  • Mix cinnamon sugar topping
  • Preheat oven to 350°F

Kitchen Tools You Will Need

  • 8×8 Pan – It needs to have high sides or your s mores cookie bars will spill out over the top.
  • Stand Mixer or large mixing bowl with a Hand Mixer to thoroughly mix the dough.
  • Microwave-Safe Bowl – Not only does it make melting chocolate or marshmallows easier, but you can use it to quickly steam vegetables too!

Storing Leftover S’more Bars

Once cool, cover the pan of s mores cookie bars tightly with foil or plastic wrap, or transfer squares to an airtight container.

Keep these treats at room temperature for up to a week. I don’t recommend storing them in the fridge as they’ll get tough and hard to chew.

S mores Bars Recipe FAQ

Can I make these bars ahead of time?

Sure! They last for up to a week, though they’re best within a few days like any other dessert.

If you plan to make them in advance, wait to add the marshmallow drizzle until just before serving.

How do I keep s’mores bars from sticking to the pan?

Be sure to grease the pan well with butter — and don’t forget a dusting of granulated sugar too!

Still having trouble? Run a knife between the pan and the bars, all around the edge, to help loosen the dessert.

You could also line the pan with parchment so it’s easier to lift the bars out, but you’d still need to add the butter and sugar for that crispy coating.

Can I double this recipe for s’mores bars?

Sure! Assemble s mores cookie bars in a 9×13-inch baking pan and increase the baking time by about 5 minutes.

Keep a close eye to make sure you don’t under- or overbake them, though. The top of the dough should appear matte instead of shiny or wet, and it will spring back when gently pressed.
