Ingredients

  • 3/4 cup (170g; 12 Tbsp) unsalted butter
  • two 10-ounce bags (566g; 11 heaping cups) mini marshmallows
  • 1/2 teaspoon pure vanilla extract
  • pinch salt
  • 9 cups (270g) crispy rice cereal

Directions

  • Line a 9×13-inch baking pan with parchment paper. Lightly grease the parchment. I always use a very light mist of nonstick spray. Set aside.
  • Melt the butter over medium heat in a very large pot. Once melted, add the marshmallows. Stir the mixture until the marshmallows are completely melted.
  • Remove from heat, then immediately stir in the vanilla extract and salt. Finally, fold in the cereal. Make sure each piece of cereal is coated with the marshmallow mixture.
  • Transfer mixture to prepared pan. Using a silicone spatula (greasing it lightly helps), gently spread mixture to fit the pan. Lightly grease the back of a flat spatula and very gently press the mixture down into the pan. Do not pack it down with force, just lightly press down until it is secure in the pan.
  • Allow treats to set for at least 1 hour at room temperature, and up to 1 day. Cover tightly if leaving out for more than a few hours.
  • Lift the rice krispie treats as a whole out of the pan using the edges of the parchment paper. Cut into squares.
  • Cover and store leftover treats at room temperature for up to 3 days. To store, place in an airtight container, with sheets of parchment or wax paper between layers.
