Start by measuring out all your ingredients. Chop any large mini Reese's Peanut Butter Cups into smaller pieces if preferred.
In a large mixing bowl, add the peanut butter-filled pretzels, Reese's Pieces, and peanuts. Toss to mix them together evenly.
Add the mini Reese's Peanut Butter Cups, semi-sweet chocolate chips, and peanut butter chips to the bowl. Stir carefully to avoid breaking up the pretzels and Reese's.
If desired, melt the semi-sweet chocolate chips and peanut butter chips together in a microwave-safe bowl. Drizzle over the mixture and stir to coat evenly.
If melted, spread the mix out on a baking sheet lined with parchment paper and let it cool until set. Break apart any clumps and transfer to an airtight container.
