In a skillet, melt butter and Caramel Creams together over medium-low heat. Stir and mix together until the Caramel Creams are totally melted into sauce.
Divide the caramel evenly among the heart molds, pressing the candy firmly to fill each mold.
Let the caramel cool over night or refrigerate it for one hour.
Cover a baking tray with parchment paper.
When the candy has hardened, remove it from the mold, and place it on the parchment paper.

Dip each candy heart in chocolate.
Decorate each candy heart with pretzel salt. Give the candies about an hour for the chocolate to cool and harden.
