    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.

    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.
