Mix corn syrup, peanut butter and sugar in large saucepan.
While stirring constantly, over medium heat, bring to a boil.
Immediately remove from heat when boiling, and stir in cornflakes, until completely covered.
Drop by spoonfuls onto wax paper or parchment paper quickly.
When fully cooled, store in a air tight container, placing a sheet of waxed paper between each layer.
Makes 4-5 dozen pieces, depending on size you spoon out. I make mine rather large. You can also spray hands with non sick spray or rub with butter and roll into balls.
