Line a cookie sheet with parchment paper. Set aside.
Place white chocolate chips in a glass or ceramic bowl and microwave for 1 minute. Add 1/3 cup peanut butter to the bowl and microwave for an additional 30 seconds. Stir until smooth.
Drop 1 mini pretzel at a time into peanut butter mixture. Turn to coat. You can dip using a fork, but I prefer using a Wilton Dipping Tool. Makes it even easier! Tap fork on the side of the bowl to help excess drip off. Transfer coated pretzel to parchment lined pan.
Repeat process with remaining pretzels. Let cool on pan until set.
Place semi-sweet chocolate chips in a sandwich sized bag. Microwave for 1 minute. Cut a corner of the bag and drizzle melted chocolate on pretzels. Let cool to set.(Or, as an alternative, online semi-sweet chocolate drizzle & sprinkle with chocolate jimmies instead.)
Store in an airtight container on the counter top & try to not eat them all at once!
Recipe yields about 100 mini pretzels, roughly 25 servings of 4 pretzels each.
