Line a large baking sheet with parchment paper.

In a medium bowl, combine the white chocolate chips and coconut oil or butter, then microwave until fully melted, stirring in between.

In a large bowl, combine the crushed pretzels, peanut butter, and chopped peanuts (if using).

Pour the melted chocolate mixture over the pretzel mixture and fold until well coated.

Drop heaping spoonfuls of the mixture onto the prepared baking sheet.

Sprinkle with sea salt if desired.

Refrigerate for at least one hour until firm.
