Gooey marshmallow-filled, chocolate-layered, graham-cracker crumb coated oatmeal cookie bars.
So did you all notice the whole new-and-improved site? I’ve been dying in anticipation for it to go live because I love it so much.
It’s be a long time in the coming…I’ve wanted to get one done for a while now, but just haven’t found what I was looking for. Until I got referred to Julie from Deluxe Designs. (Thanks Karen!!)
If anyone is looking for any kind of designer, here’s my official shout-out. Julie is awesome! Not only is she supa talented, but she’s also quick. She had my site ready to go in about two weeks! She designed all the fun elements throughout the site and the different pages and went WAY over and beyond. I’m so happy about it! P.S. Do you love the whisks everywhere? 🙂
But enough about design since you are probably here about the food.
And oh.my.gosh. do I have a dessert for you! This is officially my favorite S’mores dessert ever. Truly, my absolute favorite. I’m such a sucker for melty chocolate, gooey marshmallows, and oatmeal cookies – of course this would be my favorite.
When I was brainstorming for S’mores week, I wanted to make some kind of S’mores gooey bars. When I started to create and think more about the idea, it kind of morphed from one of my favorite desserts on this site – cookie butter oatmeal bars.
I took the base from that recipe, changed it a bit, and then added lots of marshmallows and chocolate for the center.
More oatmeal cookie pieces on top makes for the perfect finishing touch.
These bars are also SO quick to make. Faster than making a batch of oatmeal cookies and waiting for the dough to chill… And don’t be intimidated by the layers – it’s just one layer of the cookie dough, then chocolate chips sprinkled on top, then marshmallows, and finally the remaining cookie dough on top. SO easy, SO delicious, and S’MORES!!
- 1 cup old-fashioned oats
- 1 cup all-purpose flour
- 1/2 cup light-brown sugar packed
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup butter softened
- 1 teaspoon vanilla extract
- 1 and 1/4 cups semi-sweet or milk chocolate chips
- 1 and 1/2 cups miniature marshmallows
- 6 tablespoons light brown sugar
- 6 tablespoons butter softened
- 3/4 cup old-fashioned oats
- 3/4 cup (3 full) graham crackers crushed
- 6 tablespoons all-purpose flour
- Optional: handful of miniature chocolate chips
-
Preheat the oven to 350 degrees F. Line an 8 x 8 baking pan with parchment paper and set aside.
-
In a small bowl, combine all of the ingredients for the base layer. Stir until a crumbly type of dough has been formed. Press this "dough" into the bottom of an 8 x 8 baking pan.
-
Cook for 10 minutes or until lightly browned on top and remove from the oven.
-
Sprinkle the chocolate chips on top to melt.
-
Sprinkle the marshmallows on top of the chocolate chips.
-
Beat together the brown sugar and butter until light and creamy. Stir in the oats, coarsely crushed graham crackers, and flour.
-
Scoop the dough (with a cookie scoop) over the marshmallow layer. The dough doesn't cover it completely, but will cook together somewhat. Just evenly disperse scoops of dough on top of the marshmallows and briefly spread out the scoops.
-
Return to the oven for about 5 minutes (it will still be a bit gooey), then remove and allow to cool. These taste great right out of the oven, but take a good hour to fully set. If you don't mind messy bars, then dig in!
-
If desired, top the mostly cooled bars with a handful of miniature chocolate chips

Can I double the recipe and put in 9×13 pan?
Hi Rach! I haven’t tried it, but I don’t see why that wouldn’t work. You will just need to watch the baking times and adjust for a larger pan!
I made these bars this weekend and they are SOOOOOOOO GOOD!!! I had to add a few minutes in the oven (4 minutes first time in the oven, 6 minutes second time in the oven) because my oven runs cooler than it’s supposed to. But other than that, I followed the recipe exactly and they were perfect. My fiance, who doesn’t like S’mores, begrudgingly took a bite because I forced him, but then proclaimed that the bars were delicious. My father stated that the bars were the best thing he’s tasted in a long time. Thank you so much for the recipe!
Thank you SO much Sarah for taking the time to review these and I so appreciate all your kind words! Glad you fiance liked them – haha my husband was the same 🙂 He says he doesn’t really like s’mores desserts but loved these!
Making these tomorrow morning, to take & share with friends at dinner. And a great way to use up the leftover s’mores ingredients from camping this summer! Thanks for the recipe!
Yummmmmmm……I need to stop going onto foodgawker in the morning! Although this has oats in it, it is not breakfast! This is like carmelitas (http://onlyfitinjustenough.blogspot.ca/2014/01/carmelitas.html) meets s’mores….it looks so good, and this has taken first place and bumped a few things down on my list of things to make! I have a love of
s’more-ified foods, so you may be a blogging kindred spirit (if that’s o.k.!)! 🙂
I agree with Chelsea – my favorite S’mores dessert ever! I followed instructions exactly, and they turned out perfect. I refrigerated them after they cooled to make them easier to cut into bars. This one is a keeper. Just fantastic.
Yay! So great to hear they are your favorite S’mores dessert!! Still my favorite too 🙂 Thanks for the tip about putting them in the fridge for easier slicing! And thanks for the kind comment!
Hi! I’m just wondering what will happen if I sub in peanut butter instead of regular butter, then cut out sugar completely. I’ve made s’mores bars without sugar, but I used butter at that time. If I use peanut butter and a little milk, will the cookie part taste like peanut butter?
I’m sorry to not be of more help, but as I haven’t tried any of those swaps in this particular recipe I really couldn’t say if they would work out like you are thinking. I do think they would taste like peanut butter if you used that in place of the butter though.
Chelsea!!! oh my gawd, these look so good!!! After last night, you’d think I’d be all “sweets” out . . but I’m not!! Pinned!!
I made these tonight and while tasty, the top never formed a “dough” and didn’t bake into the other layers. I followed the recipe exactly. Any thoughts?
The top doesn’t really bake into the layers – it’s definitely it’s own layer that tends to mesh with the marshmallows as they get melted. I’ve never had any problems with it not baking all the way in all the times I’ve made these, so I’m not quite sure what’s going on. Did the bottom layer bake for you or was that not all the way baked either? Because that may suggest a cooler oven? Perhaps a few more minutes in the oven could bake it a little more. However, you’ll want to be careful that you don’t overcook it because the marshmallows will not be great.
can this recipe be doubled for a 9×13 pan?
I haven’t personally tried that, but I don’t see why that wouldn’t work 🙂
These look delicious! I wanted to make them ahead to bring camping this weekend. Do they keep for a couple of days? Would I have to keep them refrigerated or is room temperature okay?
They actually aren’t the best after a couple of days or so just because of the marshmallow layer (gets hard and blah tasting). If you do make them ahead wrap them SUPER tightly and room temperature is fine as long as it’s not too hot they will be great 🙂 ENJOY!
Been making these for nearly 3 years, always a 10 from everyone. I call it Death by Bob, hope that’s ok, Chelsea the real mvp. Really is the best.
Haha!! This comment made my day! I’m so happy to hear it’s a hit and I love your name for it 🙂 Thanks Bob!

I don’t see why not, but I haven’t ever tried it myself.
