Ingredients Equipment Method Notes

Ingredients
  

  • 4 tablespoons unsalted butter or salted, as preferred
  • 10 cups marshmallows preferably large, mini marshmallows work too
  • 6 cups rice cereal white or brown rice cereal for crunch
  • 1 teaspoon vanilla extract
  • optional add-ins chocolate chips, spicy nuts, pretzels, etc.

Equipment

  • Large saucepan
  • Rubber spatula
  • Greased baking pan
  • Parchment paper
  • Sharp Knife

Method
 

  1. Gather all your ingredients and tools. Have your greased pan and parchment paper ready for easy cleanup and shaping.
  2. Melt the butter in a large saucepan over low heat until it’s silky and melted, filling the kitchen with a warm, buttery aroma.
  3. Add the marshmallows to the melted butter and stir constantly, allowing them to melt completely into a glossy, sticky goo that bubbles softly and smells sweet and toasted.
  4. Once the marshmallows are fully melted and smooth, stir in the vanilla extract for a bright, fragrant note.
  5. Pour in the rice cereal all at once and quickly fold it into the marshmallow mixture with your spatula, coating each piece evenly until it turns shiny and sticky, like a glossy mountain of crunch.
  6. If you’re adding extras like chocolate chips or spicy nuts, sprinkle or fold them in now for bursts of flavor and texture.
  7. Transfer the mixture into your prepared pan, using a greased spatula or parchment paper to press it down firmly and evenly, creating a thick, compact layer.
  8. Let the treats cool at room temperature for at least 30 minutes. As they set, they will firm up and develop a satisfying crunch on the edges.
  9. Once cooled and firm, use a sharp knife to cut into even squares or rectangles. The edges should be crisp, with a chewy center that pulls apart satisfyingly.
  10. Enjoy your monster Rice Krispie treats as a fun, nostalgic snack that’s perfect for sharing or enjoying solo—crunchy, chewy, and totally addictive.

Notes

Feel free to customize with your favorite add-ins or spices for a personal twist. For extra crunch, press in some crushed pretzels or spicy nuts before cooling.
