Mix corn syrup and sugar in a microwave safe bowl.
Microwave for 4 minutes.
Spray a rubber spatula or spoon with cooking spray and stir in peanuts.
Microwave for 3 minutes.
Meanwhile spray a baking sheet with cooking spray.
As soon as the peanut mixture is done quickly stir in baking soda and vanilla and using a rubber spatula coated in cooking spray pour onto a baking sheet and spread as fast as you can before it hardens.
Once it hardens and cools, use a butter knife and roughly chop into smaller pieces.
Store in a covered container.
I like to wrap mine in decorative saran wrap or baggies, tie with ribbon, and give as gifts.
