S'mores Cookie Bar Ingredients
Here's all the yummy extras inside of these cookies that give them that true s'mores flavor:
- graham crackers, pulsed - these get mixed in to the flour, substitute a bit of flour for pulsed graham crackers so the cookies really taste like a s'mores
- graham crackers, crumbled - big chunks of graham crackers, gives you lots of graham cracker flavor, delicious!!
- white chocolate chips - these give the cookies a nice sweetness
- semi sweet chocolate chips - no s'mores is complete without chocolate
- mini marshmallows - for the ooey gooey marshmallow goodness you have to have mini marshmallows
Baking With Marshmallows
Baking with marshmallows can turn into a big glob of gooey marshmallow mess all over your cookie sheet. So doing cookie bars instead of a drop cookies keeps the marshmallow fluff contained.
If you think about a marshmallow, roasting over an open flame, it puffs up and expands. So when you bake them in the oven it's the exact same way.
How To Make S'mores Cookie Bars
The easiest way (in my opinion) to make cookies is by making them in bar form! All you need is an 8x8 baking pan and some parchment paper.
Start by creaming together butter, white sugar and brown sugar. You are looking for a pale white color, almost like a whipped butter. Then add in the vanilla extract and egg. The egg will mix easier with the butter if you have a room temperature egg.
For the graham crackers, it's best to use a mini food processor. I love mine and use it for all sorts of recipes! Sift together (mesh colander works great) all the dry ingredients. Dump everything in to the bowl and mix together but not fully combined.
Add in the mini marshmallows, white chocolate chips, chocolate chips and chunks of graham crackers. Mix it all up.
For the 8x8 baking pan, line it with parchment paper so your s'mores cookie bars don't stick to the pan. Press the cookie dough in to the pan and bake for 20-22 minutes. Then let it cool in the pan before transferring to a wire rack to continue cooling.
If you want them extra extra chewy then you only need to let them cool briefly. But if you like your cookies to be more set up, than let them cool an hour.
You can cut these into bite size cookies, little finger food size. Or you can leave them giant cookie bar size and cut them into 9 or 12 squares. I think 16 squares is the perfect size for an individual portion.
FAQ
No, because the marshmallows will expand and be all over the baking sheet. Cooking them in a square pan allows the marshmallows to expand without getting stuck to the bottom of a cookie sheet.
Of course! Get creative.
With gluten free alternatives to the flour and graham crackers, you can. I've had multiple friends have success in making these gluten free.
You will need an 8x8 baking pan to make the cookie bars.
Make sure to use the correct amount of brown sugar. Brown sugar has more moisture in it than white, which gives cookies the gooey texture. If you only use only white sugar then you get a crispy cookie that isn't as chewy ooey and gooey.

Hi- Can you freeze these after they're cooked? I'm getting married and making a ton of desserts ahead of time. Can they last in the freezer for a couple months? Thanks!
Tara Moore
Hi Andrea, I would only keep them frozen a few weeks for best taste. 3 months I find cookies start to taste old.
