In a large mixing bowl combine the coconut and cornflakes. Mix well and set aside
Bring the sugar and corn syrup to a boil over medium heat, stirring constantly
Boil until the sugar reaches “soft ball” stage, which is 235 degrees Fahrenheit.
Remove from heat and add the vanilla and peanut butter, Stir until smooth
Pour peanut butter mixture over cornflake/coconut mixture
Mix thoroughly and spread into a greased 9×11 baking dish
Cut into squares and prepare for a sugar rush like none other.
Notes
If you don't have a candy thermometer, you can drizzle a little of the boiled sugar into a glass of cold water. If it forms a soft ball that holds it's shape when you pinch it together, it’s done.
