Ingredients Equipment Method Notes

Ingredients
  

  • 4 cups Marshmallows Feel free to use vegan marshmallows if preferred
  • 6 tablespoons Butter Salted or unsalted
  • 6 cups Rice Krispies
  • 1 teaspoon Vanilla extract Optional, boosts sweetness
  • Optional Chocolate chips, sprinkles, crushed cookies Add-ins for extra fun

Equipment

  • Large mixing bowl
  • Saucepan
  • Spatula
  • 9x13-inch pan
  • Wax paper

Method
 

  1. Gather all your ingredients and tools to keep the process smooth and enjoyable.
  2. Add the butter to a large saucepan and melt over low heat, stirring gently until it’s fully melted and fragrant, about 2 minutes. You’ll notice a bubbling, golden mixture.
  3. Add the marshmallows to the saucepan and continue stirring until they melt completely, creating a smooth, glossy, sticky mixture. The marshmallows should be fully melted and bubbling gently.
  4. Remove the saucepan from heat and stir in the vanilla extract for a fragrant boost. Mix well to distribute evenly.
  5. Pour the Rice Krispies into the marshmallow mixture and stir quickly with a spatula to coat each puff evenly. The mixture will be thick and sticky, starting to set as you work.
  6. Transfer the mixture to a greased 9x13-inch pan. Use a spatula or wax paper to press down firmly and evenly, creating a large, compact layer. Press gently to avoid dense, tough treats.
  7. If desired, sprinkle chocolate chips, sprinkles, or crushed cookies over the top for extra fun. Press them slightly into the surface so they stick.
  8. Let the treats cool completely at room temperature for about 30 minutes, or until firm and set. The surface should become shiny and slightly sticky to the touch.
  9. Once cooled, cut into squares or rectangles with a sharp knife. The treats will be thick, sticky, and satisfyingly chewy with a crispy crunch on the outside.
  10. Serve your monstrous Rice Krispie Treats immediately and enjoy their chaotic, nostalgic goodness. Perfect for sharing or indulging in a sweet, crunchy mess!

Notes

For extra chaos, mix in your favorite add-ins before pressing into the pan. Store in an airtight container for up to 3 days to keep them fresh and chewy.
