Instructions

1. Line a large cookie sheet with wax or parchment paper and set aside.
2. Place the cornflakes into a large mixing bowl and set aside.
3. Add the sugar and Karo syrup to a medium saucepan.  Heat under medium heat, occasionally stirring, until the sugar is completely dissolved (about 1 minute).  Remove from heat.
4. Add the Nutella spread and stir until incorporated with the sugar mixture.
5. Pour the Nutella mixture on top of the cornflakes and gently mix to coat the cereal.
6. Spoon the mixture onto the lined cookie sheet.  I used an ice cream scoop to keep the treats uniform in size.
7. Chill for 30 minutes before enjoying.
