Course: Dessert
Cuisine: American
Servings: 12 ice cream sandwiches

Ingredients

  • 1 cup light corn syrup divided
  • 1 cup creamy peanut butter divided
  • 8 cups Rice Krispies cereal divided
  • quarts vanilla ice cream

Instructions

  • Line a 13- x 9-inch freezer-safe pan with heavy duty foil, overlapping the sides by a couple of inches. Coat the foil with nonstick cooking spray and set it aside.
  • In a large mixing bowl, use a spoon to combine ½ cup creamy peanut butter with ½ cup corn syrup. Add 4 cups Rice Krispies and mix until well combined. Pour the cereal mixture into the foil-lined dish. Spray your hands with a little nonstick cooking spray and pat the mixture down evenly into the dish. Alternately, use a small piece of wax paper to pat the mixture down. Place the pan in the freezer for about 15 minutes, or until cereal mixture is firm.
  • In a large bowl, mix together the remaining ½ cup peanut butter and ½ cup corn syrup with the remaining 4 cups Rice Krispies. Combine well and set it aside.
  • Remove ice cream from freezer and allow to soften at room temperature for about 5 minutes.
  • Remove the pan from freezer and spread the softened vanilla ice cream evenly over the top. Pour out the 2nd layer of cereal mixture over the top and pat it down on top of ice cream in same manner as before. Return the pan to the freezer and freeze until firm, about 2 hours.
  • Remove the pan from freezer and use the foil overhang to lift the giant ice cream bar from the pan and transfer it to a cutting board. Use a sharp knife to cut it into bars. Wrap the bars individually in wax paper, plastic wrap, or foil and store them in the freezer. To prevent freezer burn, place the individually wrapped ice cream bars in a gallon-size freezer-safe zippered plastic storage bag.

Notes

  • Crushed Oreo cookies
  • Chopped peanuts
  • Toffee bits
  • Mini chocolate chips
  • Chopped candy bars (Butterfinger, Snickers, etc.)
