  • 20 cups Rice Krispies Cereal just shy of 2-12-oz boxes
  • 2 sticks salted butter
  • 2 10 oz bags Jumbo marshmallows
  • 2 10 oz bags Mini marshmallows
  • 1/2 teaspoon kosher salt
  • 2 teaspoons pure vanilla


  • Line a large baking sheet with foil or parchment paper, then butter or spray with cooking spray; set aside.
  • Measure out 20 cups of cereal into TWO large bowls, dividing evenly; set aside.
  • In a large stock pot, melt butter over medium heat.
  • Once melted, stir in 2 bags of Jumbo marshmallows, melt, stirring often.
  • When melted, stir in 2 bags of Mini marshmallows and remove from heat. (The marshmallows will not be fully melted)
  • Stir in salt and vanilla.
  • Pour melted marshmallow mixture evenly over BOTH bowls of cereal.
  • Working quickly, use a rubber spatula to fold and mix the cereal and marshmallow mixture until all cereal is thoroughly coated.
  • Pour all coated cereal onto the prepared baking sheet.
  • Wet your hands with cold water, shaking off the excess, and press the cereal mixture firmly and evenly into pan.
  • All this to cool and firm up. (I place mine in the refrigerator for 30 minutes or so for faster results)
  • Lift out of the pan using the sides of the foil and cut into desired size squares.
