S’mores Cookie Bars. Yes. Can we talk about how this might be the most perfect dessert for literally any time of year? Summer cookouts, fire pit nights, random Tuesday cravings — these s’mores cookie bars show up and show out every single time. If I could only eat one dessert for the rest of my life… Well, I wouldn’t be able to choose between a S’more and a Chocolate Chip Cookie. Honestly. So, in the event I’m ever cruelly and inhumanely forced to choose between the two, I’ve come up with a contingency plan: these s’mores cookie bars, which basically take traditional s’mores and chocolate chip cookie bars and smoosh them together into one glorious bar dessert. Easy recipes like this are exactly why I keep this blog, you guys. Voila. Crisis averted. The Inspiration for S’mores Cookie Bars The inspiration for this mores cookie bar recipe actually came from the S’mores bars that my family is obsessed with at a nearby lunch place we frequent. They have the best chicken salad and sweet potato fries and DESSERTS. In all honesty, I’ve only ever tried a few of the many dessert bars they have — I tend to find something I like and obsessively eat only that one thing until I’ve completely exhausted my taste for it. And for the past year or so, it’s been these Peanut Butter Swirl Cookies that they make in-house. In fact, when I asked my husband to go grab a dessert after our meal (translation: go get me a peanut butter cookie!), I was actually irritated when he returned with a gigantic S’mores bar the size of my face. I know — who am I?? Anyway, I refused to even try a piece until he and Emma had demolished almost the entire thing. I grabbed the last little piece fully expecting to be underwhelmed. Instead… the clouds parted and angels sang and I sent my husband back for another. That I ate all on my own and never looked back.

Most of the time, the copycat recipes I attempt at home take a few tries and at least a little tweaking. I was thrilled to discover that this mores bars recipe turned out PERFECTLY on the very first try. How I Built These S’mores Cookie Bars All I had to do was make a few moderate alterations to my favorite chocolate chip cookie recipe. In a large bowl, I creamed unsalted butter with dark brown sugar and white sugar, then beat in a large egg and vanilla extract. In a separate medium bowl, I used a food processor to pulse graham cracker squares into fine crumbs, then whisked that cup of the graham cracker crumbs right into my flour mixture before I combine flour and dry ingredients with the wet. This gives the graham cracker cookie dough an on point graham cracker taste in addition to a little crispy crunchy texture in every bite — way more interesting than your average oatmeal cookie bars! To build the bars, I sprayed my square pan with cooking spray and lined it with parchment paper for easy lifting later. I pressed half of the dough into an even layer across the bottom of the pan to form the cookie base, then spread marshmallow fluff (regular marshmallows or mini marshmallows work in a pinch) right over that bottom layer. Next came a generous pile of chocolate bar pieces — I like to chop up real hershey bars for that melty chocolate, hershey’s chocolate flavor you just can’t fake. Then I pressed the remaining cookie dough into small pieces and scattered them over the top in a single layer, not worrying too much about full coverage since it spreads as it bakes. Important note: don’t skip chilling your dough if your kitchen runs warm, or you’ll have a hard time getting clean layers once you spoon marshmallow creme over that bottom cookie layer. Heat oven to 350°F, and bake until the top is golden brown and the gooey marshmallows are just barely peeking through. These seriously could not have turned out any better. I am so excited for you to try them! Like squealing-hovering-over-your-shoulder-in-the-kitchen kind of excited. If you’re into bar-form desserts as much as I am, don’t miss these Nutella Brownie S’mores Cookie Bars or the Nutter Butter S’mores Magic Cookie Bars for your next new recipe obsession. You must tell me when you try these and how much you liked them!! We like to keep ours chilled in the refrigerator, just because that’s how they’re served at the restaurant. But you can totally keep these at room temperature for a soft, gooey, perfect cookie. Once they’ve cooled completely, store leftovers in an airtight container so that graham cracker crust stays nice and intact. Tips For The Best Mores Cookies A few quick notes before you grab your mixing bowl and baking dish: use simple ingredients you probably already have on hand — purpose flour, melted butter, milk chocolate chips or semi-sweet, and a good combination of marshmallows and graham crackers for that true s’mores flavor. If you don’t have a rolling pin handy for crushing your own graham cracker crumbs, store-bought crumbs work beautifully too. Keep an eye on bake time, since every baking pan and pan size bakes just a little differently, and pull them when the edges look set but the center still looks slightly underdone — they’ll firm up as they cool. Trust me, this scrumptious s’mores bar recipe is forgiving, so don’t stress over perfection! Happy Friday, friends! S’mores Cookie Bar FAQs Can I make these bars gluten free?
