S’more Bars are the ultimate chewy gooey bar. Not quite cookie, not quite cake. All kinds of delicious. No campfire needed!
Whenever Summer rolls around (or a cold winter day when I’m longing for summer) I get a s’more craving. The graham, the chocolate, the mallow. Gahhh it is all so good. It’s one dessert that brings back all kinds of childhood memories of campfires and watching the Sandlot over and over of course.

For this recipe, I decided take all of the childhood nostalgia of S’mores and put them into one delectable ooey, gooey, chewy bar. There is a chocolate graham cookie layer, a layer of chocolate candy and a top layer of gooey marshmallows broiled to perfection.

My kiddo took one bite and said “Mama, this isn’t good….THIS IS AMAZING.” He wasn’t wrong! But don’t just take our word for it, you’ve got to try them yourselves. And today I’m showing you how.
What ingredients do you need to make S’more Bars?
These are a lot like your traditional cookie bar so you’ll find a lot of ingredients that you’d find in them: Flour, granulated sugar, brown sugar, baking soda, salt, eggs, vanilla extract and cocoa powder.
This s’mores bar recipe has a couple other ingredients to give us that classic s’mores taste.

GRAHAM CRACKERS: Instead of doing a layer of graham crackers like some s’more bar recipes, I wanted to add even more chocolate to the mix. So this recipe has a chocolaty cookie layer with graham crackers mixed in. You want to break them up into pieces but don’t make them into fine grounds. You still want pieces of graham cracker throughout the bar.
DARK CHOCOLATE CHUNKS: I used the Private Selection Dark Chocolate Chunks from my local Fred Meyer (Kroger store). If you don’t like dark chocolate you can use semi-sweet instead.
MINI MARSHMALLOWS: It’s not a s’mores recipe without marshmallows!
Step by step Photos and Instructions:
Making s’mores bars is pretty straight forward but I’ve included step by step photos and instructions here to help ensure yours turn out perfect!

- STEP #1: Beat together butter, granulated sugar and brown sugar together until fluffy. Beat in eggs one at a time. Beat in vanilla.
- STEP #2: In another bowl combine flour, baking soda, salt and cocoa powder. Slowly add dry ingredients to wet ingredients. Beat in milk. Fold in graham crackers. Batter will be thick and sticky.
- STEP #3: Press batter into the prepared baking pan. Sprinkle dark chocolate chunks in a single layer over the top. Bake in preheated oven for 15 minutes.
- STEP #4: Remove from oven. Top with marshmallows. Bake for an additional 5 minutes, turn on the broiler and broil for 30 seconds – 1 minute or until marshmallows brown slightly. Allow to cool before cutting.
Storing s’more bars:
You’ll want to store these covered on the counter. They will be freshest for a few days. And a 10 second warm up in the microwave will also give them the perfect gooey chocolaty bite.
The hardest part about this S’more Bars Recipe is trying to decide what your favorite layer is. The chocolaty graham layer, the melty chocolate candy layer or the marshmallow layer.

Or..I mean..all of the above is an acceptable answer.

[…] These have a nice spice flavor to them from the cookie butter and the cookies. I think it really makes you think of smores, without needing a fire! I want to thank Des at Life’s Ambrosia for the inspiration with her bars here. […]
I’ve been looking all over for a recipe just like this! Your s’mores bars look so delicious and easy, I love it! Thanks for sharing.
