I honestly don't remember where I got this recipe. I do know it's easy and really yummy! It's one of Austin's favorites. I've had the same treat, made with rice krispies instead of corn flakes. I've never done that but I would assume you use the same amount. It definitely gives a different texture.
1 cup sugar1 cup corn syrup
1 ½ cup peanut butter
5 cup corn flakes
Bring corn syrup and sugar to a boil over medium heat. Remove from heat, add peanut butter and stir together. Add corn flakes. Spread on wax paper to cool, cut into pieces. You can drop them on wax paper in individual cookies if desired.
