These s’more cookie bars are everything you could ever want in a dessert. You will love ooey gooey marshmallows, decadent chocolate drizzle, and chocolate chip graham cracker cookie base. These irresistible flavors combine to make addicting bars!

I am a huge fan of s’more flavored anything. Unfortunately, I don’t often find myself roasting marshmallows around a fire… These bars provide all of the classic s’more flavors with no fire necessary. Not to mention no campfire smell you can never seem to get rid of!

I developed this recipe based off of my basic chocolate chip cookie recipe. To the base recipe I added crushed graham crackers and chopped graham crackers. Then I toasted some marshmallows on top and finished them with a chocolate drizzle. Et voila! S’more cookie bars!

Ingredient Line Up

  • Unsalted, room temperature butter – Your butter is the perfect temperature when you can easily press an indention into it with your finger with a bit of pressure.
  • Brown sugar – Make sure your sugar is packed well into your measuring cup!
  • Pure vanilla extract
  • Large, room temperature eggs – If you need to bring your eggs to room temperature quickly, put them in a bowl of warm (not hot) water for 5-10 minutes.
  • Unbleached, all purpose flour – Spoon and level your flour.
  • Baking soda
  • Salt
  • Graham crackers – This recipe uses both crushed and chopped graham crackers. To crush your graham crackers, place them into a zip lock bag and roll them with a rolling pin. No mess!
  • Chocolate chips – These are incorporated into the cookie dough and the chocolate drizzle.
  • Mini marshmallows
  • Coconut oil – This is optional, but I highly recommend it any time you are melting chocolate! Adding coconut oil to your melted chocolate chips will help the chocolate harden like a shell.

How to Make S’more Cookie Bars

This recipe starts off like a typical chocolate chip cookie recipe. After the dough is prepared, press it into a 9 x 13 inch pan. I lined mine with parchment paper for easy removal! Bake the cookie bars about 12-13 minutes.

After the bars have baked a bit, spread a thin layer of marshmallows on top of the bars. Try to not let them overlap much. Bake them an additional 8-10 minutes.

If your marshmallows don’t have a nice golden layer on top, broil them for about 2 minutes. Watch them carefully so they don’t burn!

Let the bars cool, and then add a chocolate drizzle on top! Yes there are chocolate chips already in the batter.. No I do not believe you can have too much chocolate in a s’more!

Let the chocolate harden, and then cut them into squares! I eat them as is, but if you are like my husband, you might want to nuke yours in the microwave a few seconds so the marshmallows get melty again. S’more cookie bars for the win!
