S'mores Cookie Bars

S'mores Cookie Bars Super Hungry? Jump to the Recipe

I live for ooey-gooey s'mores. The messier, the better! While I love roasting marshmallows over an open fire, baking s'mores indoors can be just as tasty. These s'more bars are oozing with marshmallow and chocolate deliciousness.

The secret to soft and chewy s'mores bars is the homemade marshmallow cream - but you can totally cheat and use the store bought stuff in a pinch.

It's also best to let the bars set until they've reach room temperature before cutting - but let's be honest, if you can manage to wait that long before digging in...well, you've got more self control than I do!

  1. Preheat the oven to 350 F. In a small bowl, stir together the white sugar, brown sugar, egg, and butter until smooth. Stir in the graham cracker crumbs.
  2. Pour in the flour and baking soda. Stir until a thick dough has formed then set aside.
  3. Fill a pot of water and bring to a boil. Place a metal bowl over the boiling water to create a double boiler. Add the marshmallows and stir with a wooden spoon until sticky, then pour in the corn syrup. Stir until smooth, about fifteen minutes.
  4. Grease a 9x9 pan. Divide the dough in half. Spread half of the dough across the bottom of the pan, then place 4-5 graham crackers on top followed by the chocolate bars.
  5. Pour the marshmallow cream on top of the chocolate bars, then top with the remaining graham crackers. Tear the remaining dough into pieces to cover the exposed marshmallows (it will spread to cover the rest).
  6. Place into the oven and bake for fifteen to twenty minutes, or until golden brown on top. Remove from the oven and let set for at least an hour prior to cutting. (Optional: skip the setting and dig right in!) Enjoy!
