Monster Rice Krispie Treats are a playful, chaotic mix of crispy cereal, gooey marshmallows, and melty chocolate, creating a treat with a sticky, crunchy, and slightly messy texture.

Ingredients Equipment Method Notes

Ingredients
  

  • 1/2 cup unsalted butter or salted, if preferred
  • 4 cups mini marshmallows or broken large marshmallows
  • 6 cups crispy rice cereal fresh for maximum crunch
  • 1/2 cup chocolate chips optional, for melty sweetness
  • 1 teaspoon vanilla extract optional, for depth of flavor
  • Sprinkles or candies optional decorations for visual chaos

Equipment

  • Large mixing bowl
  • Medium saucepan
  • Spatula
  • 9x13 inch pan
  • Parchment paper

Method
 

  1. Line your 9x13 inch pan with parchment paper to prevent sticking and set aside.
  2. Melt the butter in a medium saucepan over medium heat, stirring occasionally until it smells nutty and turns a light golden color, about 3-5 minutes.
  3. Add the mini marshmallows to the melted butter and stir continuously, watching as they melt into a shiny, gooey mixture. Keep stirring until completely melted and smooth, about 3 minutes.
  4. Remove the saucepan from heat and stir in the vanilla extract, if using. This enhances the sweetness and adds a subtle depth of flavor.
  5. Pour the crispy rice cereal into the marshmallow mixture. Quickly fold everything together with a spatula until all the cereal is evenly coated and shiny with marshmallow goo.
  6. If desired, sprinkle in chocolate chips or candies and gently fold them into the mixture, distributing evenly for bursts of sweetness and colorful chaos.
  7. Transfer the mixture into the prepared pan and press down firmly with a spatula or your fingers to create an even, compact layer. Don’t press too hard—just enough to set everything in place.
  8. Let the treats cool at room temperature for about 30 minutes, allowing them to set and become firm but still chewy.
  9. Once cooled, lift the treats out of the pan using the parchment paper and cut into squares or irregular shapes for that wild, rebellious look.
  10. Enjoy your imperfect, chaotic Monster Rice Krispie Treats — crunchy, sticky, and full of fun!
