Ingredients

  • 10 cup crisped rice cereal freshly opened for maximum crunch
  • 20 oz mini marshmallows divided into two portions
  • 1 cup unsalted butter high quality, divided
  • 2 tsp vanilla bean paste substitute with extract if needed
  • 0.5 tsp sea salt fine grain
  • 7 oz marshmallow fluff for the frosting layer
  • 0.5 cup powdered sugar sifted
  • 2 tbsp heavy cream cold

Notes

Store in an airtight container at room temperature for up to 3 days. Do not refrigerate as it will make the cereal soggy. For a chocolate version, drizzle melted dark chocolate between the layers.
