Step 1

Butter a couple of baking sheets or cover with parchment paper; set aside.

Step 2

Combine sugar and corn syrup in a large saucepan and cook, stirring regularly, over medium to medium high heat just until mixture begins to boil. Do not continue to boil to avoid overcooking the sugar to a hard candy stage.

Step 3

Immediately remove from the heat; blend in the peanut butter and vanilla. Add cornflakes, a cup at a time until mixture thickens.

Step 4

Working quickly, drop by spoonfuls on the prepared baking sheet and set aside to cool.

Step 5

Yield will depend on how large you make the clusters.

Step 6

May also press out on a buttered 9 x 13-inch baking pan and cut into squares. Once dried and fully set, place into cupcake liners or bag individually.
