Ingredients

  • 30 graham cracker sheets (2 packs)
  • ¼ cup brown sugar
  • 2 cup salted butter melted (4 sticks)
  • 12 ounces mini marshmallows divided (1 bag)
  • 9.3 ounces Hershey's chocolate (6 (1.55-ounce) bars)
  • 1 cup semisweet chocolate chips

Instructions

    Cup of Yum
  1. Preheat oven to 350°F.
  2. Line a 9x13-inch baking pan with parchment paper. Add a few drops of water underneath to help keep the paper in place. Set aside.
  3. Crush the graham cracker sheets into crumbs (I like to use a food processor to help with this, but you can also place the crackers in a sealed Ziplock bag and crush them with a rolling pin), then mix the sugar with the crumbs.
  4. Add the melted butter and continue to mix until well combined.
  5. Remove about ½ cup of this mixture and keep to the side.
  6. Using the rest of the crumbs press into the baking dish to form a tightly packed base. Use the back of a measuring cup to help press evenly down into the dish.
  7. Bake in the oven for 10 minutes.
  8. Remove and top with about ¾ of the marshmallows. Bake again for 10 minutes.
  9. Remove and allow to cool for about 5 minutes.
  10. Layer the chocolate bars on top of the marshmallow layer.
  11. Evenly sprinkle the remaining marshmallows on top of the chocolate bars, then add the chocolate chips.
  12. Top all this with the remaining graham cracker crumbs.
  13. Bake again for a further 10 minutes.
  14. Cool completely before slicing. For completely clean cuts refrigerate, but allow to get back to room temperature before eating.

Notes

  • Storage: Store s'mores bars in an airtight container at room temperature for up to 5 days, in the refrigerator for up to 1 week, or in the freezer for up to 3 months.
  • You can use 1½ cups of semisweet chocolate chips (or the chocolate chips of your choice) in place of the chocolate bars. If you are feeling adventurous, you could try your favorite chocolate bar, like cookies and cream bar, Heath bar, Mr Goodbar, or Hershey’s milk chocolate with almonds.
  • You could use regular-sized marshmallows in place of the mini marshmallows; however, I would recommend cutting them at least in half.
  • You can use marshmallow creme in place of the mini marshmallows, but the bars may be more difficult to slice.
  • Instead of graham crackers, use your favorite cookies for the base, such as Oreos or vanilla wafers.
  • Top s’mores bars with peanut butter chips or chopped up Reese’s peanut butter cups for peanut butter s'mores bars.
  • Make minty s'mores by using a mix of chocolate chips and mint baking chips in place of the chocolate chips, and top with crushed candy canes.
  • Line the pan with parchment paper or foil for easy removal.
  • The marshmallows will brown slightly in the oven. If you'd like more browning, place the bars under the broiler for a few minutes or use a kitchen torch to toast the marshmallows even more. Watch carefully, as they can burn quickly.
  • Eat these straight out of the oven for a classic, melted chocolate, warm marshmallow experience or wait until they cool down and set up for a more “candy bar” like experience.
