S’mores Rice Krispie Treats

  • 6 tablespoons butter
  • ¼ cup brown sugar
  • 7 cups mini marshmallows divided (5 cups to be melted with butter and 2 cups mixed in whole)—see notes
  • 1 teaspoon vanilla
  • ¾ teaspoon salt
  • 1 - 7 ounce container marshmallow cream about 2 ¼ cups
  • 3 cups rice krispies
  • 2 cups graham cracker crumbs about 11 full graham cracker sheets
  • ¾ cup chocolate chips I like to use mini semi-sweet chocolate chips or half milk-half semi-sweet, but you decide what kind of chocolate to use!


  • ¼ cup chocolate chips I like semi-sweet, but you choose!
  • ½ teaspoon oil or butter
  • 1 cup mini marshmallows
  • sea salt


  • In a very large saucepan over low heat (see notes), brown your butter. Once butter is browned, add in your brown sugar. Mix until completely dissolved,
  • Then, add in 5 cups of mini marshmallows and
    coat in butter-brown sugar mixture. Keep stirring until butter and marshmallows are completely melted, then remove from heat.
  • Stir in the vanilla, salt, graham cracker crumbs, and Rice Krispies until completely coated.
  • Mix in marshmallow cream. Once marshmallow creamis completely incorporated, let cool until just barely warm and then stir in the reserved 2 cups mini marshmallows and chocolate chips.
  • Line a 9x13 pan with parchment paper and spray with cooking spray. Pour all of the mixture into the 9x13 pan. Using the back of the spoon evenly distribute the mixture throughout the pan. Spray your hands
    with cooking spray (so the mixture doesn’t stick to your hands) and press the mixture down so the treats have a smooth surface.
  • Once cool, start your topping. In a microwave safe bowl, heat your oil (or butter) and chocolate chips together in 15 second increments, stirring in between. Repeat this until you have a smooth mixture.
  • Sprinkle your mini marshmallows over top of your S’mores Rice Krispie treats, then drizzle the chocolate over top, and sprinkle your sea salt over the top. Let cool completely, then slice and enjoy!


  • Mini marshmallows—you’ll need about 14 ounces of mini marshmallows, I buy 2-10 ounce bags
  • If you don’t have a very large sauce pan, you can either melt the butter and marshmallows down in the largest saucepan you have and then pour them into a large mixing bowl or you can microwave them in a large microwave-safe bowl and then our into an even large mixing bowl to mix in the cereal.
  • PLEASE NOTE: I doubled this recipe as shown in photos to get an extra thick rice krispie treat. The recipe listed above is half the thickness of the rice krispie treats. If you would like  them as thick as the photos, double the ingredients for the base, but do not double the ingredients for the topping
