Make this easy snack in the microwave. Measure cereal into large bowl. Butter rectangular pan, 13x9x2 inches. Microwave 5 cups marshmallows, the chocolate chips, corn syrup and butter uncovered in large microwavable bowl on High 2 minutes to 3 minutes 30 seconds, stirring after every minute, until melted and smooth when stirred. Stir in vanilla. Continue as directed in recipe.
If you spray your bowl with cooking spray before using it, you'll have less mess to clean when you're done.
Just for fun, use Cinnamon Grahams cereal instead of Golden Grahams.
