There’s just something so incredibly yummy about s’mores. Whether you’re eating them in the forms of cookies or the traditional way, no matter the method, the bite is always filled with nostalgic memories.

Sometimes, it’s not always realistic to have a fire at home. Because we couldn’t make a fire, I decided to try out these amazing s’more cookie bars in the oven instead.

Why This Recipe Works

  • So easy to make
  • Perfect for all seasons
  • Minimal ingredients

BAKE: Bake for 30 minutes or until lightly golden on top. Cool bars completely or refrigerate before slicing and serving.

Tips for Easy S’mores Bars

  • Make both of the cookie layers at the same time before layering all the ingredients. This uses an extra piece of parchment paper, but I found it to work the best!
  • If your house is on the warm side or the bars or not incredibly firm, then you can place them in the freezer or refrigerator to harden them up.
  • Marshmallow creme is crucial to this recipe. Mini marshmallows do not work well, but I have not tried the jumbo marshmallows.


Can you freeze cookie bars?

Yes! You can freeze these s’mores cookie bars. Make sure you place them in an airtight storage container or bag.

How long do these s’more cookie bars last?

If you can manage to keep them around, these cookie bars will last in an airtight container at room temperature for a week.

How many bars does this make?

This recipe makes nine nicely sized cookie bars, but feel free to cut them into smaller sizes if you would prefer!

    • Thank you very much!! In step #3 it tells you to “Divide dough in half and press one half of the dough into the bottom of the pan. Lift the parchment paper and dough out of the pan and set aside (this is the top layer).”
