Ingredients
  

Base Ingredients
  • 6 cups crisped rice cereal
  • 10 oz mini marshmallows about 1 standard bag
  • 0.25 cup unsalted butter half a stick
  • 1 cup graham crackers roughly chopped
Flavorings & Add-ins
  • 2 tbsp key lime juice freshly squeezed
  • 1 tbsp key lime zest finely grated
  • 0.5 cup white chocolate chips optional
  • 1 pinch kosher salt

Equipment

  • 9x13 inch baking pan
  • Large heavy-bottomed pot
  • Silicone spatula
  • Parchment paper

Method
 

  1. Line a 9x13 inch baking pan with parchment paper, leaving an overhang on the sides. Lightly grease.
  2. In a large pot, melt the butter over medium-low heat.
  3. Reduce heat to low. Add marshmallows and stir continuously until completely melted and smooth. Remove from heat immediately.
  4. Stir in the fresh key lime juice, key lime zest, and a pinch of salt until well combined.
  5. Gently fold in the crisped rice cereal and chopped graham crackers until everything is evenly coated.
  6. Let the mixture cool for just a minute or two, then fold in the white chocolate chips if using.
  7. Transfer the mixture to the prepared baking pan. Using lightly greased hands, gently press into an even layer without packing it down tightly.
  8. Let set at room temperature for 30-60 minutes before slicing into squares and serving.
