Ingredients

  • 3½ tablespoons unsalted butter or salted butter, omitting the salt

My Favorite Halloween Candy Mix:

  • 4 snack-size Reese's Peanut Butter Cups
  • 3 fun-size Hershey's bars
  • 3 Milky Way minis
  • 5 Snickers minis

Instructions

  • Line an 8×11½-inch baking dish with parchment paper; set aside.
  • Place butter in a microwave-safe bowl and microwave for 30 seconds until melted.
  • In a separate large microwave-safe bowl, combine marshmallows and melted butter, tossing until marshmallows are well coated. Microwave for 2-3 minutes until marshmallows are completely melted.
  • Quickly stir in vanilla extract and salt until well combined.

  • Add remaining Rice Krispies and mix until well combined.
  • Fold in half of the chopped Halloween candy, incorporating completely into the mixture.
