In a small microwave-safe bowl combine butterscotch chips and peanut butter. Microwave the mixture for 30 seconds at a time, stirring in between each, until it is smooth.

In a large bowl combine peanuts and chow mein noodles. Pour the melted butterscotch mixture over them, gently stirring until everything is well coated.

Drop the mixture onto parchment paper to form 2-2.5 inch piles. Let them cool until the butterscotch is fully hardened.

Serve or store in an airtight container for up to 1 week.
