Preheat oven to 200°F. Line a cookie sheet with a parchment paper or a silpat mat. Line pretzels on cookie sheet in a single layer then top each pretzel with one square of the Hershey's bar. Bake in preheated oven for 4-5 minutes, just until chocolate is shiny and soft.

Remove from oven and sprinkle with crushed candy canes. You may need to push the candy canes down gently into the melted chocolate to make sure they stay. Place in refrigerator or freezer to set for about 5 minutes. Store in an airtight container for up to 7 days or in the freezer for up to 3 months.
