Remove foil wrapper from each Chocolate Kiss.
Combine sugar and corn syrup in a large pan. Over medium heat, stir until the sugar is dissolved.
Turn the heat to low. Add the peanut butter and stir until completely combined and creamy.
Remove pan from the heat and add the cereal. Stir to just combine.
Using a small cookie scoop, immediately spoon a few cookies at a time onto the parchment paper.
Add the Kiss to each cookie using your fingers to form the cookie around the Kiss. Continue the process until all the peanut mixture has been scooped (you will need to work fairly quickly as the cookie mixture in the pan will harden.)
Let the cookies cool on the parchment paper.
Store in an airtight container on the counter or the refrigerator.
