Ingredients

  • 3 cups golden grahams or 12 sheets of graham crackers plus extra for the top
  • 1 cup salted butter
  • 24 oz mini marshmallows divided (20 oz, 3 oz mixed in, 1 oz on top)
  • ½ teaspoon vanilla
  • ½ teaspoon kosher salt
  • 5 ½ cups rice krispies cereal
  • 3 oz milk chocolate chopped roughly (2 regular or dark hershey bars)

Instructions

  • Line a 9x13 pan with foil all the way over the edges for easy removal, then grease with non-stick spray.
  • Put the cereal or graham crackers in a ziploc bag and use a rolling pin or other object to break up the cereal into chunky pieces, small, medium, and big.
    3 cups golden grahams or 12 sheets of graham crackers
  • In a large pot, melt the butter over medium heat. Continue cooking until the butter is foamy and a light golden brown.
    1 cup salted butter
  • Turn the heat to low and immediately add 20 oz marshmallows, vanilla, and salt. Stir with a rubber spatula until the marshmallows are completely melted and smooth. Remove from the heat onto a counter or surface that isn’t hot.
    24 oz mini marshmallows, ½ teaspoon vanilla, ½ teaspoon kosher salt
  • Add the rice krispies and cereal/graham crackers and stir until mostly combined. Add another 3 oz of marshmallows. Mix gently until everything is combined. Careful not to overmix.
    5 ½ cups rice krispies cereal
  • Pour the mixture into the prepared pan, then use the spatula to press gently until it’s roughly even across the pan. Be sure to press very gently for soft rice krispie treats.
  • Sprinkle with the remaining 1 oz marshmallows.
  • Optional: Broil, watching carefully until they are toasted.
  • Gently press the remaining graham crackers pieces and chocolate pieces around. Allow to cool to room temperature (or just dig in while they’re warm!), then cut and serve.
    3 oz milk chocolate

Notes

Tips & Tricks
  1. Work quickly. Once it cools even a bit, it gets really hard to handle and mold. 
  2. Use fresh marshmallows!
  3. Broiling is optional. They look cute, but will get a crispier layer on top that is a bit tougher to cut through. 
  4. To get them perfectly flat, you can spray a piece of plastic wrap lightly with non-stick spray. Lay it across the rice krispie treats and finish pressing with a flat-bottomed measuring cup until they are even. Don’t press too firmly or it will make them tough and hard. 
  5. Spray rubber spatula with nonstick spray or wipe with oil to keep it from sticking and slowing down the process.
