S’mores Bars are a great way to enjoy s’mores all year round, and you don’t even need to build a fire. This tasty treat is made with a graham cracker cookie dough sandwiched around melty milk chocolate and gooey marshmallow.

Like hot s’mores dips’mores peanut butter cups, and Nutella stuffed cookies, this recipe is every bit as gooey, sweet & crunchy as the traditional campfire version.

The Perfect Trio

  • Graham crackers.
  • Melty milk chocolate.
  • Sticky, gooey, even slightly crisped marshmallow.

Also known as s’mores, are a fun treat associated with Girl Scout campfires. It’s a chocolate bar topped with a roasted marshmallow that is sandwiched between two graham crackers! The name is part of the charm, because after eating one, it won’t be long before you’ll ask for “some more”.

To Make S’Mores Bars

Kids can have almost as much fun making s’mores bars in the kitchen as they do eating them! Like millionaire’s shortbread bars, these slightly messy, multi-layered dessert bars are always a favorite.

  1. Dough: In separate bowls, combine the wet and dry ingredients, then gradually mix together.
  2. Layer: Press 2/3 of dough in bottom of pan, layer marshmallow fluff and chocolate bars on top. Then drop and spread the remaining dough on top.
  3. Bake: Sprinkle with chocolate chips and bake until ooey gooey and the cookie layer is fully cooked.

Allow the s’mores bar to cool before cutting and serving.

Tip: When making the top cookie layer, don’t try to cover the entire pan. The chocolate and marshmallow will ooze through the gaps, becoming slightly crisp, like the charred outside of a campfire-roasted marshmallow!

Can You Make These in Advance?

You can absolutely make s’mores bars in advance! They are a welcome addition to any picnic or potluck. Just cool the pan completely, cut and store in the refrigerator to allow them to firm up.

A s’mores cookie bar is the perfect dessert to bring to a simple burger and hotdog cookout or chili fest!

How to Store S’mores Bars

Make an extra pan to keep s’more bars around whenever you need a quick and convenient dessert or after school snack.

  • Refrigerate: Cool completely and place in freezer bags or air tight containers and store in the fridge for up to a week.
  • Freeze: Place in freezer bags or air tight containers in the freezer for up to four months.
  • Thaw: leave out on the counter until room temperature, then serve.

  1. I also make a s’more bar recipe and it is alot easier than yours. Ingredients are oatmeal, flour, brown sugar, butter, soda, salt and milk. Also, milk chocolate chips, mini marshmallows and semi sweet chips melted for glaze.

  2. This came out ok for me. The flavor is not what I expected. One small piece is plenty, I will be trying it again with vanilla ice cream on top! Yum! It’s not overly sweet which was nice!3 stars
