Cost: $5


  • 8 tablespoons unsalted butter
  • 15 ounces marshmallows use mini or regular sized; about 1 1/2 (10 ounce) bags
  • 2 teaspoons vanilla extract
  • 9 cups Rice Krispies Cereal
  • 1 cups Halloween M&Ms
  • 1/2 cup Halloween Sprinkles
  • 1 cups candy corn


  • Line a 9x13-inch baking pan with foil and spray with cooking spray. Set aside.
  • Melt the butter and the marshmallows in a medium sized saucepan over medium-low heat. Once the marshmallows are melted, remove from heat and stir in the vanilla. Quickly stir in the cereal. Stir in the candy and sprinkles.
  • Pour the marshmallow-cereal mixture into the prepared baking dish. Press to flatten. (I like to spray my hands with cooking spray and use them to press the treats into the pan – just be careful not to burn yourself.) Cool completely before cutting into squares.
