  • 1/2 cup unsalted butter
  • 10.5 ounces mini marshmallows
  • 6 cups Rice Krispies cereal
  • 20 Oreo cookies crushed (I used Heads or Tails Double Stuff)
  • 1/2 cup rainbow sprinkles


  • Liberally butter a 9x13 baking pan. Set aside.
  • Combine cereal, crushed cookies, and sprinkles in a large bowl.
  • In a saucepan set over low heat, melt butter. Add marshmallows and stir with a rubber spatula until marshmallows are completely melted and smooth.
  • Pour melted marshmallow over cereal and stir until everything is completely coated and begins to clump. Transfer mix to prepared baking pan and gently press treats down, creating an even layer.
  • Allow treats to cool completely (35-60 minutes) before cutting into 12-16 squares.
  • Treats are best enjoyed the same day. Wrap any extras in plastic wrap - they're great in lunchboxes!
