Before getting started, make sure to gather all of your ingredients and measure everything out. Line a couple of large baking sheets with parchment paper
Add sugar and syrup in a saucepan over medium heat. Stirring often, bring to a low boil and cook for one minute.
Remove from heat and add the vanilla and peanut butter. Stir until peanut butter is melted and the mixture is smooth.
Stir in the cereal and mix until all of the cereal are coated with the mixture and everything is well combined.
Drop spoonfuls of the mixture onto the prepared baking sheets. Allow to cool for about 1 hour or until the cookies have firmed up. The cookies will continue to firm up more the longer they cool. Enjoy!
Sprinkle with salt if desired
Store in an airtight container on the countertop for 1 week.
