Ingredients Equipment Method Notes

Ingredients
  

  • 10 cups large marshmallows preferably fluffy, skip mini marshmallows for stretchiness
  • 1/2 cup unsalted butter adds richness and gloss
  • 6 cups crispy rice cereal toasted for extra flavor, optional
  • 1 cup chocolate chips milk or dark, for ooziness
  • to taste sprinkles or candies for colorful chaos
  • a pinch sea salt optional, brightens sweetness

Equipment

  • Large saucepan
  • Spatula
  • 9x13 inch baking dish
  • Cooling rack
  • Measuring cups and spoons

Method
 

  1. Measure out all your ingredients, lining up marshmallows, butter, and cereal for an easy flow.
  2. Heat your large saucepan over medium heat, and melt the butter until it’s bubbling and fragrant.
  3. Add the marshmallows to the melted butter, stirring constantly until they melt into a glossy, gooey mixture, about 3 minutes.
  4. Remove the pan from heat once the marshmallows are fully melted and shiny—your kitchen will smell sweet and buttery.
  5. Quickly fold in the cereal and toppings using a spatula, ensuring everything gets coated evenly in the marshmallow goo.
  6. Transfer the sticky mixture into a prepared 9x13 inch dish lined with parchment paper, pressing down firmly but gently to shape the giant treat.
  7. Press extra toppings or sprinkles into the surface for colorful chaos, then let it rest at room temperature for about 30 minutes to set.
  8. Once set, use a sharp knife to cut into large, messy squares—clean the knife between cuts for neat slices.
  9. Serve immediately or store in an airtight container for a delightfully gooey, chewy, and crunchy chaos that everyone will love.
