Here are the ingredients you need to make this s’mores bar recipe!

  • Butter – use unsalted butter
  • Brown sugar
  • Egg
  • Vanilla extract
  • Milk – any type of milk works – 2%, 1%, fat free.
  • All-purpose flour
  • Baking soda – this is rising agent use to get a slight rise in the crust mixture.
  • Graham crackers – this goes into the crusts and is also a topping for the S’mores Bars.

So as you can see, s’mores bars are made with pantry-friendly ingredients, and it comes together in no time!

How to make S’mores Bars

To make these s’mores cookie bars, you will also need a 9″x13″ rectangular baking dish, or something very similar in size.

Start by greasing the dish with cooking spray. Then set it aside and let’s get working on the graham cracker crust, which will be the bottom of the s’mores bars.

Bring softened or melted butter, brown sugar, egg, vanilla extract, milk to a big bowl and whisk to combine. Then add the dry mixture – flour, baking soda, and crushed graham crackers.

Make sure graham crackers are crushed finely so that it will incorporate well to form the crust. I typically bring graham crackers into a zip lock bag and use a meat tenderizer to beat it until they are in small fine pieces.

Once the mixture is combined, bring it to baking dish and spread it out evenly using a spatula.

It is a fairly thin layer but it will rise when baked because there’s baking powder in it.

Let the crust bake and rise for about 10 minutes, then remove the baking dish from the oven and add the rest of the toppings to it.

This is the fun part as we turn the crust into actual S’mores Bars! We will be adding all the important S’mores ingredients to it and then melting them in the oven so they are warm, gooey, and taste like S’mores you make in a campfire.

First comes the chocolate chips….

Then comes the marshmallows and graham crackers!

Note that graham crackers on top are in bigger pieces than the finely crushed graham crackers in the crust. What I do is I simply use my hands to break them into smaller pieces.

At this point, your kitchen will probably be filled with the aroma of chocolate combined with sugar and graham crackers, but hang in there with me for a little bit and bring that baking dish bake into the oven.

Bake it for 5-7 minutes, or until the chocolate and marshmallows are melted.

If you want the char the tops of the marshmallow, broil it for an additional 1-2 minutes in the oven.

I highly recommend that we continue to practice patience and let the S’mores Bars cool completely because this is the thing, it is messy to cut into these S’mores Bars when it is warm.

We want everything to set and slightly harden before cutting into it.

Now if your patience is running out and you desperately need to stuff your face with S’mores Bars asap, have at it and go for it, just know that you won’t get nice clean cuts of the squares when doing that.

I take one bite into this yum thing and I’m transported to summer nights sitting by the campfire roasting s’mores. Layers of chocolate, marshmallows and graham crackers are distinct yet merge together beautifully.

S’mores bars are crumbly, buttery, gooey, rich, and everything your s’mores-loving heart will ever need! 💛

  • Spray the baking sheet with cooking spray or line with parchment paper before adding ingredients to the dish.
