Ingredients Equipment Method Notes

Ingredients
  

  • 6 cups Crispy Rice Cereal
  • 1 10-ounce bag, plus 1 cup Mini Marshmallows Use a fresh bag for best results
  • 4 tablespoons Unsalted Butter
  • 1 large Lemon zested and juiced
  • 1 teaspoon Vanilla Extract
  • 1/4 teaspoon Salt

Equipment

  • 1 Large Pot or Dutch Oven
  • 1 9x9 inch baking pan
  • 1 Spatula

Method
 

  1. Grease a 9x9 inch baking pan with butter or non-stick spray. For extra-easy removal, line the pan with parchment paper, leaving some overhang to use as handles.
  2. In a large pot or Dutch oven, melt the butter over low heat. Add one 10-ounce bag of mini marshmallows and stir continuously until they are completely melted and smooth. Be careful not to overheat.
  3. Remove the pot from the heat. Immediately stir in the lemon zest, lemon juice, and vanilla extract until well combined.
  4. Add the crispy rice cereal and the remaining 1 cup of mini marshmallows to the pot. Gently fold everything together with a greased spatula until the cereal is just coated.
  5. Transfer the mixture to your prepared pan. Using the back of the greased spatula or a piece of wax paper, gently press the mixture into an even layer. Do not press down too firmly. Let them cool at room temperature for at least 1 hour before cutting and serving.

Notes

Use Fresh Ingredients: Always use a fresh bag of marshmallows for the best texture.
Low and Slow Heat: Melt marshmallows over low heat to prevent them from getting hard.
The Gentle Press: Do not compact the treats into the pan. A light press is all that's needed for soft, chewy results.
