S’mores Cookie Bars

Close up of hands breaking a s'mores cookie bar in half with the marshmallows pulling and green plant in the background.

These s’mores cookie bars are the epitome of summer! They are based off my S’mores Cookies, but in bar form! All you need is one bowl and mostly ingredients you might already have. Fluffy from the marshmallows, perfect chewy and doughy. All the best flavors from s’mores but in cookie form, yes please! Such a great recipe to feed a crowd as well, just double the recipe! Also delicious when topped with vanilla ice cream, but isn’t everything?

  • Unsalted butter- You can use salted as well but I always go for unsalted in baking. If you use salted, you don’t even have to change anything. Make sure the butter is at room temperature, it makes a huge difference!
  • Brown sugar- Brown sugar gives it that caramel note and adds the perfect sweetness as well as giving them that deep rich brown color.
  • Granulated sugar- A classic in any recipe. You can use white sugar, cane sugar, whatever you prefer. I haven’t tested coconut sugar.
  • Egg- The egg helps bind the recipe and really help give it taste and texture. Make sure these are room temperature as well (on the counter for at least an hour) to help the recipe bind together better. I don’t know if flax eggs would work as an alternative.
  • Vanilla extract- No cookie recipe is complete without vanilla extract in my opinion. It’s key!
  • All-purpose flour- I typically bake with all-purpose flour. Almond and coconut flour do not have the same measurements so they will not work for this. However, gluten-free 1:1 all-purpose flour should work just fine. Make sure to find one with xantham gum, I love Bob’s Red Mill, but any should do.
  • Baking soda- Helps to produce a light and fluffy and perfectly cooked cookie bar.
  • Sea salt- Salt is key in a baked good, because it really helps to bring out the flavor!
  • Chocolate chips– I used semi-sweet for this recipe, but feel free to use anything. Dark, milk, or even your favorite chocolate bar chopped up!
  • Marshmallows- You have to have marshmallows for s’mores! I used mini marshmallows, because they work best in these s’mores cookie bars!
  • Graham crackers- Adds the perfect extra sweetness and flavor to make them s’mores.

  • Make sure to take the s’mores cookie bars out of the oven around 20 minutes. They will definitely seem undercooked a little, but you want them nice and soft. Over baking would be so sad!
  • Let them cool completely before cutting. I know, I know no one ever likes this because who the heck can wait? But if you want them to be able to cut into bars, then they have to cool completely! However, if you want to dig in, just cut and enjoy the gooey warm goodness!

  1. The recipe list calls for an 8” square pan but the text says that is too small.

  2. What size crumbs do we want with the graham crackers?

    • Hi!! So I typically just crush them in a plastic bag with a wooden spoon. They don’t have to be perfect, you may want some thicker crumbs for texture and then more fine ones 🙂
