Soft and chewy cookie layers sandwich gooey marshmallows, melted chocolate chips and crushed graham crackers in these easy cookie s'mores bars. They only require 4 ingredients and take 10 minutes to prep.
Ask me any day what my favorite dessert is (to eat and to make), and I will always tell you cookies. Our chocolate chip pudding cookies are famous on the internet and I love creating new cookie recipes. Or an edible cookie dough recipe if that's your style (like my husband). But sometimes you need store bought dough to keep it simple. So for those times I created these cookie s'mores bars!
The combination of chocolate, cookies, marshmallow and graham crackers is unmatched in flavor. The melty chocolate and marshmallow ooze out of the sides with each bite of these delicious bars. They're so great this time of year (summer), but they're really the perfect treat anytime you need something quick and easy, but still delicious.
4 Simple Ingredients for S'mores Bars
- Cookie dough: the base is a thick layer of soft and chewy cookies while the top is more scattered to let the marshmallow peak through. I recommend using a store bought cookie dough to keep it simple. We used Sweet Loren's cookie dough because it's gluten and dairy free, but Tollhouse works great too. If you want to make homemade cookie dough, follow our pudding cookie recipe and use that.
- Chocolate chips: The chocolate chips go on top of the first layer and when they're in the oven they melt into an even layer of gooey chocolate. Use milk chocolate chips if you want the true s'mores flavor (or even hershey’s chocolate bars), but we used dark chocolate chips to keep them dairy free.
- Graham crackers: grab your favorite graham (gluten-free if you want) and crush them up over the chocolate chips.
- Marshmallow creme: this is marshmallow fluff that comes in the jar. Do not swap this for mini marshmallows because they will get too hot and melt into the cookies and you won't be able to see them at all.
How to Make S'mores Bars
- Press half of your dough in a single layer in the bottom of the prepared pan. We used about 2 packs of cookie dough fro this. Use your fingers to press the dough into the pan to create one layer of dough, without any holes in between.
- Sprinkle the chocolate chips evenly on top and spread them out so the cookies are almost covered in chocolate.
- Crumble the graham crackers up and sprinkle them on top of the chocolate layer.
- Scoop the marshmallow fluff on top and use a spatula to spread it out into an even layer. Spray the spatula with nonstick spray before spreading if you're having trouble with it sticking.
- Finish by spreading a thing layer of the remaining cookie dough on top. Press the dough out flat between your fingers and lay them in rows on top of the marshmallow. It's ok if the marshmallow is showing through. This is actually what you want so the marshmallow seeps through when they're baking so you can see the top when you cut them.
- Bake them for 25-30 minutes, until the cookies are set and just golden brown. Keep a close eye on them the last 10 minutes to make sure the edges of the cookies and the marshmallow don't burn.
Expert Tips
Keep the layers in the order described. The graham cracker's don't stick to the cookies when they're baked so the s'mores bars will fall apart if the graham isn't in between the mallow and the chocolate
Don't use real regular marshmallows. They will get too hot and melt into the cookies and you won't have that thick layer of gooey marshmallow seeping oout.
Underbake them slightly because they will keep baking when you take them out of the oven. Over-baking could result in a hard cookie bar and we're looking for
Spray a spatula with non stick spray to make it easier to spread the marshmallow
