Ingredients Equipment Method Notes

Ingredients
  

  • 4 cups Rice Krispies Puffed cereal
  • 1/2 cup butter Salted butter recommended
  • 10 cups mini marshmallows For gooeyness and binding
  • 1 cup chocolate chips Melts into decadent pockets
  • 1/2 cup mini marshmallows Extra gooeyness and texture
  • 1/2 cup colorful candies Add chaos and color
  • 1 teaspoon vanilla extract Optional but adds sweetness

Equipment

  • Large saucepan
  • Large mixing bowl
  • Spatula or buttered spatula
  • 9x13-inch baking pan
  • Parchment paper or butter for greasing

Method
 

  1. Gather all your ingredients and prepare your equipment, including a large saucepan, mixing bowl, and a greased 9x13-inch pan.
  2. Melt butter in the large saucepan over low heat, hearing the sizzle and watching it turn glossy and golden.
  3. Add mini marshmallows to the melted butter, stirring constantly until they melt completely, creating a smooth, gooey mixture that bubbles softly and smells sweet.
  4. Pour the melted marshmallow mixture over the Rice Krispies in the large mixing bowl, then gently fold with a spatula until the cereal is evenly coated and sticky.
  5. Add chocolate chips, the remaining mini marshmallows, and colorful candies to the mixture, folding gently to distribute all the add-ins evenly and keep the treats vibrant and chaotic.
  6. Transfer the mixture into the prepared pan, pressing down firmly with a buttered spatula or parchment paper to create a dense, even layer.
  7. Allow the treats to cool at room temperature for at least 30 minutes, until they are set, firm, and slightly shiny on top.
  8. Once cooled, cut into squares or fun shapes, revealing the gooey, chocolatey, colorful chaos inside, ready to enjoy immediately or store for later.

Notes

For extra fun, add pretzels or sprinkles for additional crunch and visual chaos. Keep the mixture pressed tightly into the pan to ensure clean cuts and a cohesive treat.
