These S’mores Cookie Bars are so much easier than making individual cookies and they have perfect flavours for summer baking enjoyment. Makes a large pan, so great for picnics, BBQs or bake sales, too.
I don’t do as much baking in the warmer months, but there’s always room for a little bit. These S’mores Cookie Bars are a great summer treat, with the classic S’mores flavours in a quick and easy bar form. The recipe makes a large 9×13 pan, which will yield 24 bars, so it’s great for feeding large groups and summer entertaining.
I like to make these with semi-sweet chocolate chunks (available in with the chocolate chips at most grocery stores). Regular chocolate chips work as well though. Once cooled, these bars are nice and sturdy, so they travel well. These freeze well, too!
I like to trim the outside edges of bars like this, then cut into even squares. Makes for a nice neat bunch of squares, plus you get to eat the trimmings (hate to waste ;)
Cook’s Notes for S’mores Cookie Bars
Don’t be to skimpy when measuring out the mini marshmallows. I say “generous” 2 cups in the recipe, which means heap it up a bit :)
I find bars like these easiest to cut cold, so I like to pop the pan into the refrigerator for a bit before cutting. That said, these bars are best enjoyed at room temperature or slight warm (pop them into the microwave for a few seconds!).
I prefer semi-sweet chocolate in my S’mores, as I find milk chocolate to be too sweet (and that’s something I rarely say ;). That said, if you prefer, milk chocolate works just fine, as well. As I mention above, I like chocolate chunks, for a chunkier finish, but chips will again, also work just fine.
Don’t need a big pans worth? Cut the recipe in half and bake up in a 8×8-inch square baking pan. Baking time will be slightly less.
S'mores Cookie Bars
Quick, easy and delicious, these bars have all the flavours of S'mores, in cookie bar form. Great for BBQs, picnics or bake sales.
Ingredients
- 2 cups all purpose flour
- 2 cups graham cracker crumbs
- 1 tsp baking powder
- 1/4 tsp salt
- 1 cup unsalted butter at room temperature
- 1 1/2 cups light brown sugar packed
- 2 large eggs lightly beaten
- 2 cups mini marshmallows heaping
- 1 1/2 cups semi-sweet chocolate chunks a bit more if using chocolate chips
Instructions
-
Preheat oven to 350 F. and grease and line a 9x13 baking pan with parchment paper, ensuring that the paper along the long sides extends above the pan a bit, to act as handles to remove from the pan later. Set aside.
-
In a large bowl, whisk together the flour, graham cracker crumbs, baking powder and salt. Set aside.
-
In a large bowl with an electric mixer or in the bowl of a stand mixer with a paddle attachment, beat together the butter and brown sugar until light and fluffy, about 2 minutes. Scrape down sides of bowl. Add eggs and beat until well combined. Reduce mixer to low and slowly beat in the flour mixture until combined.
-
Remove and set aside about 1/4 of the dough. Press the remaining dough into the prepared pan to form a thin, even layer on the bottom of the pan. Top with chocolate chunks, then marshmallows. Scatter the reserved dough over-top in clumps. It won't/shouldn't cover the entire top, as you want the chocolate and marshmallows to show through the top.
-
Bake in preheated oven until golden brown, about 30-35 minutes. Set pan on a wire rack to cool completely, then lift out of pan by grabbing the parchment paper. Remove to a cutting board. Trim the outside edges, if desired, then cut into squares.

All I have to say is I have a new favourite square!!!! Sooo delicious and I have to confess I increased the marshmallows even more;) Thank-you so much for sharing!
So glad you are enjoying them, Kristen! Thanks so much :)
Found this recipe as I was searching for a s’mores bar and I have to say they are delicious! They were a big hit along with my other cookies I make during Christmas time and everyone agreed that they need to be on my normal rotation. I actually just put another batch in the oven for my niece’s birthday party. Thank you for sharing it!
So glad you are enjoying these, Krista :) Thanks!
These became part of my annual Christmas cookie baking list last year – everyone loves them. I made them vegan by using Earth Balance (vegan butter) instead of regular butter, and by substituting about 1/4 cup of soy yogurt for each egg. (Also used vegan marshmallows). They have turned out so well every time. Great recipe! :D
So glad to hear, Sarah! Thanks :)
These were ridiculous great! :) Thank you for sharing! I doubled recipe for a 18x13x1 pan for a large group and it worked so well!
So glad to hear, Ashley :) Thanks!
These look awesome! Can these be made with Reese’s mini’s?
I’ve never tried it Allison, but it’s worth a try :)
These are so good! I ended up reducing the sugar by half (I tend to reduce the sugar in cookies that have a lot of sugary mix ins) and bumped up the salt to 1tsp. It’s just my husband and I so I put most in the freezer once cut and we love eating them cold like that – they’re super good!
So glad you enjoyed them, Alice! Thanks :)
I make these when I go to BBQ’s or potlucks and they are always a hit! They are absolutely delicious!
Glad to hear that, Jennifer :) Thanks!
Mine didn’t look quite the same, as I was heavy handed on the marshmallows and could have saved a bit more dough for the top. but the taste is great and they look awesome on my tray. Taking them to a church pot luck today with instructions on how to get the full experience with a few seconds in the microwave. I think that will be fun…it IS February. :)
So glad to hear and yes, February needs S’mores! :)
Just made these gorgeous s’mores! What a great recipe. Actually, I am sort of addicted to all your sweet posts ;-)….made butter tart muffins and the peach cake earlier this week. Will I ever get out of the kitchen (and when will e stop eating all these delicious treats!). Thank you for sharing, very much appreciated. With love from Amsterdam.
So glad and I don’t think my sweet tooth is going anywhere, so there will surely be more sweets to come :)
Wow this looks so amazing! I definitely need this in my life!
Thanks so much, Eden :)
S’mores in a bar form…now that is the perfect answer for those of us without a fire pit. :D
Thanks Karen. We have a fire pit, but I still like to have these around ;)
Yes yes and YES! S’mores anything calls my name but I think your recipe is one of the best ones I’ve seen. Love it.
Thanks Sarah and I can tell you, these are deliciously addictive little cookie bars:)
There is always room for baking if it involves bars… and especially if it involves S’mores flavors! These look scrumptious, Jennifer!! I actually think I would prefer these to traditional S’mores… but shh don’t tell the classic I said that. ;) Cheers, friend!
Thanks so much, Cheyanne and I think I prefer them, too ;)
Oh I love that melted chocolate and gooey marshmallows! I’ve been thinking about s’mores lately – and these would cure that craving for sure. A beautiful cookie bar Jennifer! Sharing!
Thanks Tricia :)
Oh my gosh, that close up picture is amazing Jennifer. I’m lusting for one (or two) of these bars, they look amazing!
Thanks Chris. Hard to stop at one of these :)
I love these gooey s’mores bars, such a perfect weekend treat!
Thanks Laura :)
Making today for a friend’s Eagle Scout ceremony! Just in time! Thanks!
So glad! Enjoy :)
I love anything that involves gooey marshmallows, these bars are pretty much my ultimate dessert!
Thanks Sara. I’m always all in with gooey marshmallows, too :)
Thanks Sue and yes, I love the convenience, too. Seems we never have the s’mores stuff around when we have a campfire. (Not very organized here :)
We make these every summer, well, actually we make them every season, who am I kidding? I love the convenience, and I think they taste better than the campfire version! Your photos make my mouth water :)
Jennifer these are the ULTIMATE summer treat! I cannot wait to make these! Summer would not be complete without something s’mores! And that photo of the stacked bars!! OMGee!!
Thanks Mary Ann :)
I love that these freeze well, Jennifer. I can make these ahead of time and take them camping. Perfect for the rainy days when no one wants to sit around the fire!
I seriously want some photography lessons – gorgeous!
Thanks Robyn :) These would be perfect for a camping treat!
