Frequently asked questions – FAQ
How to store these s’mores cookie bars
You can store these bars in an airtight container at room temperature for up to 3 days.
Can I freeze these cookie bars?
Yes! You can either wrap the whole cooled-down baking pan and freeze it for up to 2 months. Or you can wrap each individual cookie bar with plastic wrap and place them in an airtight container or freezer bag and store them in the freezer for up to 2 months.
Once you are ready to enjoy them, allow them to thaw at room temperature for a few hours before enjoying them again.
Is there any way to simplify this recipe?
If you want to simplify this recipe even more, you can use the premade dough for the top and bottom layer of cookie dough and fill the center as you would the regular one. The cool thing is that you can use the store-bought chocolate chip cookie dough or any other cookie dough you like for this!
Can I use regular marshmallows instead of marshmallow fluff?
This is a great recipe because of the marshmallow fluff in the center. Even though I don’t recommend using mini marshmallows or any other size for that matter because you wouldn’t get the same melty effect with those. You gooey cookie bars would have more of a chewy vibe because of the set marshmallows but they would still be delicious nonetheless.

My kid’s birthday’s are one day apart so we had a cookout and I made these instead of cake. Needless to say everyone loved them!!
Going to make them next time we go camping or to future cookout’s. Definitely recommend
Thank you so much and glad they were a hit!
oh my god these are sooo good, i am afraid of how fast i may eat this entire pan…
I struggle with the same problem lol!
These were good, but looked nothing like the photo. No nice layers. It seems like the fluff disappeared, and I used more than the recipe called for. And 10 minutes to make? It took 10 minutes to get the first sticky layer spread out in the pan, probably 30 minutes total to put it together. I’m a seasoned baker and had a hard time with this. Next time I will add slightly more crushed graham crackers to the dough. I will definitely give them another try!!
Hmm, the layers may have disappeared from pressing too hard when putting on the top layer, or if you sliced them into layers if they weren’t fully cooled. Give it another shot and let me know 🙂
Delish!! Working on new recipes for my son’s cookie table at his wedding and these are fab. Only thing I need is moar fluff!!!
Ahh that’s so special!! I love that you’re making treats for his cookie table, such a fun tradition. I’m so glad you enjoyed these!
Made these for a gathering and they were a huge hit! Very rich so a small piece was plenty for each person, and I’ll definitely be making them again.
Recipe was amazing, family loved! Thank you for putting the measurements with the directions!🙌🏻 scrolling back and forth is so frustrating.
I’m glad it was helpful!
can you make this with marshmallows instead of the fluff?
Fluff is best just because it’s easier to spread.
can you make the cookie part and freeze it ahead of making it?
Yes you can 🙂
Haven’t made these yet, but HUGE shout out to you for putting the ingredients with each step!!! It’s such a pain to keep scrolling up and back each time!! Awesome!! Trying these tomorrow for 4th of July 😊
I’m glad that was helpful! I hope you liked them!
Can you toast the fluff? Also, do you freeze the top and bottom layer, or just top?
Sure you could use a torch to toast the fluff before putting on the top cookie layer, that’s a pretty good idea actually! And it’s only the layer that goes on top that gets frozen. It’s just to prevent it from burning while the layers underneath cook.
Oh my god! These were sooooo good! And super easy to make. Mine didn’t take 5 bars and I made the mistake of not buy enough fluff (I was missing half a cup) but it turned out amazing.
