Step 1

Put the cornflakes in a bowl big enough to stir and set aside.

Step 2

Melt chips and peanut butter in a microwave-safe bowl in 30-second intervals, stirring between bursts. Repeat just until it's all smooth and melty, then stir in a teaspoon of vanilla.

Step 3

Pour the warm mixture over the cornflakes, and working gently, use a rubber spatula to coat the cornflakes evenly with the creamy mixture.

Step 4

Drop by tablespoons onto waxed or parchment paper-lined baking sheets and cool.

Step 5

Keep in a tightly covered container in the refrigerator or a cool place.
