Some types of Hershey Kisses melt quicker than others. The classic milk chocolate one takes about 3-4 minutes. I’ve found the Hershey’s Hugs take 2-3 minutes and don’t hold their shape as well as the classic. If you prefer, you can place them on different sheet pans so you can watch the timing and pull the Hershey’s Hugs ones out sooner.
You can use any sprinkles that you like for this recipe. I prefer the nonpareils because they’re tiny and really crunchy.
You can store these at room temperature in an airtight container for 5 days. The pretzels will start to get stale after that. For longer storage, you can refrigerate them, but again the pretzel will begin to get stale after 5 days.
