How To Make Peanut Butter Cornflake Cookies

Tear off two large sheets of waxed paper (about 12 x 16 each) and spray them lightly with cooking spray. Set aside on a table or countertop.

Place sugar and corn syrup (or light honey/maple syrup) in a large pot over medium-high heat.

Stir constantly as it comes to a boil. As soon as it comes to a boil, remove it from the heat.

Immediately stir in peanut butter until smooth.

Pour the entire box of cornflakes in and stir rapidly until coated.

Like this.

Drop spoonfuls of the cornflake mixture onto the greased waxed paper and allow them to cool completely before storing them in an airtight container.

These are so chewy and good!

All of your peanut butter lovers will flip and those who remember these from their childhood might even tear up a bit after the first bite.

Enjoy!
