Preheat the oven to 325°F and line a baking sheet with parchment paper.
Place the shortbread cookies on the baking sheet at least ¼ inch apart.
Slice the caramels in half and place on each cookie. Bake 6-8 minutes, or until caramels melt. Cool 20 minutes.
Once the caramel is hard enough to touch, microwave chocolate wafers at 30-second intervals until melted, stirring in between.
Drop cookies caramel side down in the chocolate then use a fork to gently flip them and scoop them out of the bowl. Scrape off excess chocolate before placing back on baking sheet to set.
Top with sprinkles or sea salt before the chocolate hardens.
Store in an airtight container at room temperature for up to 1 week.
