In a large saucepan, stir together corn syrup, honey and peanut butter. Bring to a boil, then remove from heat and stir in vanilla. Add cornflakes and toasted coconut to saucepan and stir until cereal is well coated with peanut butter mixture.

Drop cornflake mixture by heaping teaspoons onto a foil-lined baking sheet. Transfer to refrigerator and let cool until firm, at least 20 minutes. Store in refrigerator in an airtight container.
