Easy S’mores Bars, the best summer potluck cookie recipe! Loads of graham crackers, chocolate, and marshmallow all in one cookie and no fire pit needed!
Do you like s’mores? I love them, but not always convenient to have a fire when you’re in the mood for one. These Easy S’mores Bars will help with those s’mores cravings. I made them late at night so unfortunately I didn’t take any pictures while I was going along, but they’re easy to make I swear!
Yes, I know there are many s’more bar recipes out there. The ones I have seen are all made in small pans. A small pan is not going to cut it. I made these in a 13×9-inch pan and trust me, go with the 13×9 inch pan version! These s’more cookies will go FAST! If you want to spruce these cookies up a bit you could add all sorts of things like nuts, peanut butter, bananas, toffee bits, coconut, etc.
Some recipes call for the king size chocolate bars, but I used regular sized chocolate bars. Unfortunately, you do need quite a few to fill a 13×9-inch pan (like 9 chocolate bars…) so look for a multi-pack in the candy section of your grocery store.
You could also just use chocolate chips if you want or melt the chocolate chips, spread on wax paper, cool until hard, and use that instead of the chocolate bars. If you do just use chocolate chips, it may take some extra effort spreading the marshmallow fluff on top since you won’t have a flat surface like the bars. Hope you enjoy these Easy S’mores Bars as much as we do!
Hope you enjoy!
Easy S'mores Bars Cookie Recipe
Ingredients
- 2 1/2 cups all-purpose flour
- 1 1/2 cups graham cracker crumbs
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1 cup unsalted butter softened
- 3/4 cup light brown sugar
- 3/4 cup granulated sugar
- 2 eggs
- 2 teaspoons vanilla
- 9 regular size chocolate bars (such as Hershey's)
- 16 ounce tub marshmallow fluff
Instructions
- Preheat oven to 350 degrees F. Lightly grease a 13x9-inch baking dish with shortening or nonstick spray.
- In a medium bowl, mix together flour, graham cracker crumbs, baking soda, and salt until well combined.
- In a separate large bowl, mix together butter and sugars with an electric mixer on medium speed until well combined. Mix in egg and vanilla until well combined then flour mixture.
- Spread half of cookie batter on bottom of baking dish using your fingers or back of a fork. Top with chocolate bars in a single layer. Break chocolate bars as needed to cover cookie dough. Spread marshmallow fluff on top of chocolate. Take remaining cookie dough in small amounts and flatten in hand then place on top of marshmallow fluff covering as much of the marshmallow as possible.
- Bake cookie bars for about 25 to 30 minutes or until golden brown around edges.
Recipe Notes
SNAPPY TIPS: The top layer of cookie dough can take a little practice. Be sure to flatten in your hands rather than trying to spread the dough over the marshmallow.
SNAPPY SUBSTITUTIONS: Instead of regular size chocolate bars, you can use the king size bars or chocolate chips. Do NOT substitute marshmallows for the fluff. Marshmallows will melt in the oven and the cookie bars will not turn out well.

Lisa, these look AWESOME and so yummy! Perfect for summer and no camp fires required! : )
allie @ Through Her Looking Glass says
Dear Lisa, these bars are pure decadence! You are so right. A small pan just ain’t gonna cut it. Not in our household of four boys anyway….can’t wait to try this awesome recipe!
Ally's Sweet & Savory Eats says
I make this same recipe (or it’s very similar), they are always a hit, especially in the summer!
Leah says
These bars didn’t work for me. Maybe because I used marshmallow instead of fluff?
Lisa Huff says
Yep, that would do it. You can not substitute marshmallows for fluff. Marshmallows melt very quickly in the oven and definitely would not work well in this recipe.
Heather says
I’ve made these before using a slightly different recipe. These just came out of the oven and I can’t wait to try them! My little tip: spread the to layer of cookie dough out on a sheet of wax paper, then lay over the marshmallow fluff. Easy peasy!
Misty Colby says
This is the same recipe from 8/26/14 on Cooking Classy. You just doubled it to make a larger pan. tsk tsk
Lisa Huff says
There are hundreds of S’mores cookie/bar recipes on the internet so I can see how they would all be similar. I’ve never seen that particular one until today and although similar they are not exactly the same. Thanks for letting me know of the similarities.
Anna-Marie says
I’m making these for the 4th time. Easy and freaking delicious……
Lisa Huff says
4th time, oh my goodness that’s fabulous! Happy to hear you enjoy them!
Jess says
Just made 3 batches for a graduation celebration tomorrow! So far so good, I’m waiting til they cool to cut into one for a taste test. Pressing the top layer of dough on wax paper is definitely the way to go-I can’t imagine trying to spread it onto that gooey marshmallow fluff.
Lisa Huff says
Oh wow, 3 batches! They are delicious so I’m sure they’ll go fast! Hope the graduation celebration goes well!
NL says
How far in advance can you make/keep these? Any suggestions for storing?
Lisa Huff says
I haven’t had to store them long because they typically go fast, but I would suggest keeping them in the pan (so they don’t try out), cover well, and I’d put them in the fridge (although they’d be fine on the counter, I just like to put things in the fridge in the summer when it’s hot), and I’m sure they’d be fine at least a few days if not longer.
Jessica says
Is it better to serve them straight out of the oven or cooled? I’m making them tonight.
Lisa Huff says
Hi! Sorry, just seeing this. I would suggest letting them cool otherwise the center will be really mushy. I personally like them cold and put them in the fridge sometimes. :) Hope you liked them!
Diane D. says
I would love to try this recipe. Is the marshmallow fluff easy to spread on top of the chocolate bars or can it go in the microwave for 30 seconds or so to help it spread easier?
Lisa Huff says
It’s not bad to spread. I would suggest putting smaller spoonfuls around the pan then use an offset spatula to spread. Since the chocolate bars are flat it’s not too hard to spread but if you use chocolate chips instead it may be a bit more difficult. You could also put the chocolate bars upside down so they’re even more flat. I would not suggest putting it in the microwave because it may melt too much.
Liz says
These are AMAZING. Thank you for the recipe. (I patted out the upper crust on a flexible cutting board, thanks to other bakers for the idea).
Lisa Huff says
Thank you! So happy to hear you enjoyed!
