Over the past few years, s'mores bars (any combo of chocolate, marshmallow, and graham cracker) have skyrocketed in popularity. They've been featured everywhere from cooking shows to bakery windows—and even on fancy restaurants' dessert menus. The most exciting part about them, though, is that no two s'mores bars are exactly the same. Some use chocolate bars, while others use brownies; some are layered, while others are a conglomeration of all the ingredients in one.

Recently, I have perfected my own take on the s'mores bar (complete with three tasty layers), so I thought I'd share the wealth. This recipe is easy enough to make in a dorm kitchen, and provides you with enough servings to feed all your neighbors.

  • Step 1

    Preheat the oven to 350ºF and spray a 9-in x 13-in pan with Pam or another cooking spray.

    #SpoonTip: Use a disposable pan, or line your pan with non-stick tin foil. Otherwise, the marshmallows will create a sticky mess.

    Mix the bowl contents evenly, so that the crust sticks to itself. Pack the crust into the bottom of the pan.

    Melt the chocolate chips and the remaining 12 ounces of butter on the stovetop at a very low heat. Be patient, and stir constantly to avoid burning the chocolate.

  • Step 7

    Add the flour, stirring gently to make sure all flour is mixed in.

    #SpoonTip: Too much mixing will make the batter very tough, so go easy.

  • Step 9

    Put the pan in the oven and bake for about 30 minutes, or until brownies are fully cooked.

    #SpoonTip: To test if they're cooked, insert the tip of a fork into the brownies. If it comes out clean, you're good to go.

  • Step 10

    Allow the crust and brownies to fully cool. This may take about 20 minutes.

    Put the pan in the oven on broil for about one minute. Carefully watch as the marshmallows brown because it does not take long for them to burn.

    That's it! Remove the pan from the oven, and let your bars cool before cutting into them. Enjoy!
