How to Make Fudge Sundae Ice Cream Cake

  1. In a medium saucepan, combine 1 cup light corn syrup, 1 cup granulated sugar, and 1/2 cup (1 stick) unsalted butter. Bring to a boil over medium-low heat, stirring constantly until sugar dissolves and mixture is smooth.
  2. Remove from heat and immediately stir in 4 cups Rice Krispies cereal until well coated.
  3. Press the Rice Krispies mixture firmly into the bottom of a greased 9x13 inch baking pan.
  4. In a separate bowl, combine 1 cup creamy peanut butter, 1 cup fudge sauce (store-bought or homemade), and 1/4 cup light corn syrup. Mix until smooth and well combined.
  5. Spread half of the peanut butter fudge mixture evenly over the Rice Krispies crust.
  6. Freeze for at least 2 hours, or until completely firm.
  7. Once firm, spoon approximately 2 quarts of slightly softened ice cream (your choice of flavor!) evenly over the frozen peanut butter layer.
  8. Warm the remaining peanut butter fudge mixture gently in the microwave or on the stovetop until pourable.
  9. Drizzle the warm fudge mixture over the ice cream layer.
  10. Freeze for at least 4 hours, or preferably overnight, until solid.
  11. Let the cake stand at room temperature for about 10-15 minutes before serving to allow for slightly softer ice cream.
  12. Garnish with shaved chocolate, crushed peanuts, chopped maraschino cherries, marshmallow fluff, sliced bananas (optional), or any other desired toppings.
  13. For an extra burst of flavor, consider drizzling strawberry jam over the top before adding other toppings.
