Heat oven to 375 degrees F

Line a baking sheet with parchment paper

Place pretzels in a single layer on baking sheet

Unwrap caramels, placing one on each pretzel (you can also cut the caramels in half if you want them to be less sugary)

Place baking sheet into oven on the middle rack and leave in for about 3 minutes (less if you halved the caramels)

After 3 minutes, the caramels should be quite soft

Remove the baking sheet and press one Smartie into each caramel

Place in the freezer to set for about 5 minutes

Enjoy these at room temperature and store in an airtight container (not that you'll have many left to store...)
