  • 1/3 cup corn syrup
  • 1 cup semi-sweet chocolate chips
  • 1/2 tsp vanilla extract
  • 4 cups graham cracker cereal
  • 3 cups miniature marshmallows divided


  • Line an 8-inch or 9-inch baking pan with non-stick foil. Set aside.
  • Combine 2 cups of marshmallows and cereal in a large, heat-safe bowl.
  • Pour corn syrup into a microwave-safe bowl container. I used a glass Pyrex measuring cup.
  • Microwave corn syrup for 1 minute on high heat.
  • Stir in chocolate chips until melted.
  • Quickly stir in vanilla extract.
  • Pour chocolate mixture over the top of the cereal and marshmallows and stir until coated.
  • Scoop contents into the prepared baking dish and press down with the bottom of a measuring cup or large spoon.
  • Refrigerate for a few minutes until the chocolate has set up. Top with remaining cup of marshmallows and place under broiler for 1-2 minutes or until golden brown.
  • Cut into squares and serve.
