Preheat oven to 250 degrees.

Arrange the square pretzels evenly on a baking sheet lined with parchment paper.

Unwrap each Hershey Kiss and place one on in the centre of each pretzel.

Place the baking sheet in the oven on the middle rack for exactly 4 minutes.

Remove the tray from the oven and immediately place a pink or red Smartie or M&M in the centre of the chocolate kiss. Slightly press the candy into the chocolate.

Allow the chocolate to cool completely before transferring to a bowl or a cellophane bag.
